Moves
========

Behold, OU's most defining set. Tyranitar's impeccable stats, unique typing, monstrous Special Defense in sand, and vast movepool enable it to fulfill many different roles simultaneously. Crunch is a reliable STAB attack that maims Pokemon like Starmie, Rotom-A, Celebi, and Latias for tremendous super effective damage. Most foes that it hits neutrally, like Flygon and offensive Suicune, will still sustain quite a bit of damage. Its chance to lower a foe's Defense is also crucial for breaking defensive Pokemon like Zapdos and Clefable. Payback is an alternative to Crunch on much slower variants, as it usually becomes more powerful, but it has fewer PP and forgoes the chance of a Defense drop. Dark Pulse is another interesting alternative to hit Rotom-A hard even in case of a burn, and it also hits Reflect Starmie for more damage; however, Crunch is almost always better.

From there, Tyranitar can use many different moves to accommodate its team's needs. Fire Blast is a fantastic option to hit Skarmory, Breloom, Scizor, and Bronzong for massive damage. In particular, 2HKOing physically defensive Skarmory makes Tyranitar a potent threat against stall builds. As alternatives, Stealth Rock and Ice Beam are great moves. Tyranitar makes fantastic use of Stealth Rock, as its insanely high Special Defense and solid HP actually make it a check to Starmie, despite its weakness to Water-type attacks. In addition, it can put up sand to disrupt Water-types like Suicune and Kingdra, and with Passho Berry it can serve as a soft check to them. Having the ability to keep Stealth Rock up versus Starmie is an incredibly desirable trait, as Starmie is terrifying offensively and also OU's most consistent spinner by far. Ice Beam surprises foes like Gliscor, Flygon, and Dragon Dance Dragonite with an OHKO; it can also hit physically defensive Zapdos for solid super effective damage.

Tyranitar is the best Pursuit trapper in OU thanks to its high Attack and tremendous bulk. Pursuit decimates Psychic- and Ghost-types like Starmie, Rotom-A, Latias, and Gengar on the switch; Tyranitar needs to hold a Choice Scarf to reliably trap Gengar, however. Tyranitar can also use Pursuit to wear down foes as they switch out, like Clefable, Zapdos, and even Jolteon, Suicune, and Draco Meteor-locked Kingdra. For some teams, however, the threat of Pursuit is enough, and Tyranitar can use moves like Fire Blast and Ice Beam in its place to form more dedicated mixed attacking sets.

Stone Edge is Tyranitar's most powerful STAB attack, which hits Gyarados, Dragonite, Zapdos, and Togekiss super effectively. It can also be used to fish for a critical hit against bulkier Pokemon like Clefable, Suicune, and Blissey. Earthquake is a great alternative to reliably cover Nidoqueen, Heatran, Magnezone, Infernape, Calm Mind Jirachi, and Lucario. As a bonus, it can hit Zapdos as it uses Roost, which surprisingly makes a large difference in the matchup. It may be just as effective to use a combination of moves like Crunch + Earthquake versus Zapdos as it is to use Stone Edge, as the latter only has an effective four PP due to Zapdos's ability Pressure. This means that Zapdos may be able to use Roost in succession to reduce Stone Edge's PP. Superpower hits Heatran, opposing Tyranitar, and Lucario for massive damage; it also hits Clefable and Blissey super effectively, often OHKOing the former and coming very close to OHKOing the latter. Using Superpower will make Tyranitar worse off versus Zapdos, however, so it may want to run Ice Beam alongside it.

Set Details
========

It's extremely important to note that this Tyranitar set can run a large number of viable EV spreads. Depending on the moveset, it may want more or less Special Attack investment, more Special Defense investment, or even more Speed. The above EV spread has an emphasis on Special Defense, which Tyranitar uses to even further strengthen its effectiveness versus a large variety of special attackers, like Zapdos, Rotom-A, Latias, Starmie, Heatran, Kingdra, and Suicune. 52 Special Attack EVs allow Fire Blast to OHKO uninvested Breloom and significantly improves the move's damage output versus Skarmory. 80 Speed EVs enable Tyranitar to outpace uninvested Skarmory; however, if you use Fire Blast, you may want to invest more Speed at the expense of Attack or Special Defense to let Tyranitar outpace faster Skarmory, Breloom, and Scizor. The rest of the EVs are invested into Attack to maximize it given the constraints. If you use Ice Beam and Fire Blast, you may want to invest a bit more EVs in Special Attack to allow Tyranitar to shut down Skarmory and Gliscor more effectively.

Passho Berry is what largely enables Tyranitar to turn the tide on all Water-types. There is not a single unboosted Water-type move that OHKOes Tyranitar—not even +1 Gyarados's Waterfall or Choice Band Swampert's Torrent-boosted Waterfall with the Defense drop from a Lonely nature. This item is especially effective versus Rain Dance sweepers like Kingdra and Ludicolo, as Tyranitar can come in on a Hydro Pump, set up sand, and still be relatively healthy. Alternatively, Custap Berry takes advantage of Tyranitar's tremendous bulk, which often enables it to survive two attacks and be within Custap Berry's activation range. This can give it an extra chance to attack or set up Stealth Rock, which Passho Berry often doesn't do. Alternative items like Lum Berry and Chople Berry can be used as well. Lum Berry can help Tyranitar to beat Will-O-Wisp Rotom-A, and Chople Berry can be used for Mach Punch Breloom and, more importantly, Focus Blast Gengar. It can often be difficult to justify these options over Passho Berry and Custap Berry, however, as Rotom-A can miss with Will-O-Wisp and often still loses to Tyranitar, and Tyranitar is more reliable versus Gengar with a Choice Scarf.

The choice between a Lonely, Adamant, and Brave nature is mostly set dependent. If you're using Fire Blast without Ice Beam, you may want to invest more Speed without lowering Tyranitar's Special Attack with an Adamant nature, so a Lonely nature fits best in these situations. An Adamant nature is best when you don't opt for any special attacks, such as with a moveset like Stealth Rock / Pursuit / Crunch / Earthquake. A Brave nature is a decent alternative to Lonely, reducing Tyranitar's Speed rather than Defense, which is often a good choice; however, a Lonely nature allows Tyranitar to just barely outspeed Clefable, which can be quite significant depending on the team.

Usage Tips
========

Switch Tyranitar in on special attackers like Zapdos, Rotom-A, and Latias. When facing Water-type special attackers like Starmie, Kingdra, and Suicune, try to pivot into a Water-resistant teammate before switching into Tyranitar so there's less likelihood of Tyranitar sustaining a Water-type attack as it switches in. If you're using a less expected move like Ice Beam or Fire Blast, keep it concealed until Tyranitar lures the right target in, like Skarmory or Gliscor. If you notice that Rotom-A has Leftovers, it almost certainly has Will-O-Wisp, so try to play around that by switching into a Fire-type Pokemon or a burn absorber like Clefable, Blissey, or Roserade. When you are sure your foe will switch out, Pursuit is very often a great option to wear it down, even against Dark-resistant Pokemon like Heatran and Magnezone.

If you're using a Custap Berry, pay close attention to Tyranitar's HP as it gets lower. Be cognizant of entry hazards and how much HP Tyranitar will have after sustaining damage from Stealth Rock and Spikes. Doing so potentially enables Tyranitar to use its Custap Berry after switching in when it wasn't able to prior. Try to familiarize yourself with how much damage Tyranitar takes from an opposing Pokemon's attack to open up the potential for long-term planning with Custap Berry's activation in mind.

Team Options
========

Tyranitar is the quintessential Pokemon that supports all of its teammates rather than the other way around, and it fits on almost any team. However, there are a few Pokemon that work well to support any set this Tyranitar can run. Infernape and Heatran can switch into Will-O-Wisp. Their devastating Fire-type attacks melt Steel-types like Metagross, Bronzong, Jirachi, and Lucario, which all give Tyranitar trouble. Both can also use Grass coverage to wear down bulky Water- and Ground-types like Swampert, Milotic, Hippowdon, and Suicune. Choice Band Infernape can lure in Starmie, Rotom-A, and Latias and use U-turn to get Tyranitar in freely. Heatran can use Magma Storm to trap, cripple, and even remove foes like Swampert, Milotic, and Zapdos. Gyarados often switches into Infernape and Heatran and sustains significant damage from powerful Fire-type attacks, which helps Tyranitar. In return, Tyranitar can trap and remove Starmie, Choice Scarf Rotom-A, and Latias for Infernape and Heatran, as well as wear down Zapdos and Flygon. Its ability Sand Stream also helps keep Suicune, Zapdos, Gyarados, and Milotic in check by interfering with their Leftovers recovery, which Infernape and Heatran appreciate. Gyarados is a great teammate for Tyranitar as well, as it can switch into Earthquake from the likes of Swampert and Flygon and boost its Attack and Speed with Dragon Dance, setting up for a sweep. Tyranitar wears down Zapdos and checks Choice Scarf Rotom-A, Latias, Choice Scarf Heatran, and Starmie for Gyarados. A Starmie of your own can spin entry hazards away to help keep Tyranitar and Flying-types healthy. Starmie also checks Infernape, Water-types, and Ground-types. Zapdos can spread paralysis with Discharge, switch into Fighting- and Ground-type attacks, and threaten bulky Water-types, all of which makes Tyranitar more threatening. Tyranitar's 4x Fighting-type weakness means that Fighting-immune Pokemon like Gengar and Rotom-A pair quite well to ward off most Fighting-types. Latias resists Fighting-, Water-, and Grass-type attacks, while Tyranitar resists Ghost- and Dark-type attacks. Magnezone's ability to trap Skarmory and Scizor enables Tyranitar to drop Fire Blast for Stealth Rock more easily. Jirachi can support Tyranitar in various ways, whether it paralyzes foes with Body Slam, lures in Tyranitar's checks and removes them with coverage moves like Grass Knot and Thunderbolt, or wears down the opposing team with an Iron Head barrage.

Payback is probably worth a mention somewhere as a possible alternative over Crunch if you are consigning yourself to being slow with a tankier spread. Also worth mentioning that if you are forgoing Fire Blast, Magnezone is a nice partner to get Skarm and Zor.

In particular, 2HKOing physically defensive Skarmory makes Tyranitar a potent threat against stall builds. As alternatives, Stealth Rock and Ice Beam are great moves. Tyranitar makes fantastic use of Stealth Rock, as its insanly high Special Defense and solid HP actually make it a check to Starmie and other Water-types like Suicune and Kingdra, despite its weakness to Water-type attacks. Since Starmie is very frail and dark weak (means it is one-shot by Crunch), Ttar can check it only if it carries passho berry by surviving 2 hydros at full. However, it does not check Kingdra because it usually carries a life orb or a choice specs which makes it considerably stronger than most Starmie and can 2ko passho ttar with hydro pump while not being okoed in return. Same goes for offensive Suicune that can easily 2KO it with one calm mind boost and survive every hit. So I would reword this sentence by saying that Tyranitar's high special defense allows it to survive the strongest water moves of the metagame and can provide support to shut the threats down especialy WITH passho berry. Otherwise, it s a bit difficult. Having the ability to keep Stealth Rock up versus Starmie is an incredibly desirable trait, as Starmie is terrifying offensively and it's also OU's most consistent spinner by far. Ice Beam surprises foes like Gliscor, Flygon, and Dragon Dance Dragonite with an OHKO; it can also hit physically defensive Zapdos for solid, super effective damage.

Tyranitar is the best Pursuit trapper in OU thanks to its high Attack and tremendous bulk. Pursuit decimates Psychic- and Ghost-types like Starmie, Rotom-A, Latias, and Gengar on the switch; it needs to hold a Choice Scarf to reliably trap Gengar, however.

It may be just as effective to use a combination of, say, Crunch and Earthquake versus Zapdos as it is to use Stone Edge, as the latter only has 8 PP, meaning it can only use the move four times due to Zapdos's Pressure. This means that Zapdos may be able to use Roost in succession to reduce Stone Edge's PP. Superpower hits Heatran and Lucario for massive damage, but more importantly it hits Clefable and Blissey super effectively Steel-type coverage is also very appreciated (+ohkoing foe's ttar), I just do not like the wording "more importantly" it s good because it hits both, often OHKOing the former and coming very close to OHKOing the latter. Using Superpower will make Tyranitar worse off versus Zapdos, however, so it may want to run Ice Beam alongside it.

Heatran can use Magma Storm to trap, cripple, and even remove foes like Swampert, Milotic, Zapdos, and Clefable. For clef, that's not really how heatran supports ttar Gyarados often switches into Infernape and Heatran and sustains significant damage from powerful Fire-type attacks, which helps Tyranitar. In turn, Tyranitar can trap and remove Starmie, Choice Scarf Rotom-A, and Latias for Infernape and Heatran, as well as wear down Zapdos and Flygon. Its Sand Stream helps keep Suicune, Zapdos, Gyarados, and Milotic in check by interfering with their Leftovers recovery, which Infernape and Heatran appreciate.

All those teammates you mentioned are pretty legit. But on top of that, it seems really important to me to highlight the fact that ttar absolutely needs fighting-resistant teammates to switch in the ultra common Mach Punch / Superpower Loom, Close Combat mainly since it s really powerful and ttar's slowness gives them free shots. Here all the mons you mentioned are fine, stuff like gengar, latias, rotom-a also works quite well at doing this.
Also, starmie provides spin support to Dragonite and Gyarados which can act as fighting-type checks in offensive teams and same goes for Zapdos (not sure if mentioning this is worth it, but starmie + ttar + flying is definitely one of the most common archetype).

Nice quality, just added some comments. QCed after you checked.

 

[Bughouse]

While I understand Tyranitar is a fundamentally flexible Pokemon and therefore difficult to write an analysis for, this slashitis is really bad.

Can it not be split into multiple sets?

While I understand Tyranitar is a fundamentally flexible Pokemon and therefore difficult to write an analysis for, this slashitis is really bad.

Can it not be split into multiple sets?

I don't think it should. If it were divided into multiple sets, both sets would play way too similarly to one another and it would be hard to differentiate them. The way it is slashed here, although it's a lot, I don't think it's way too excessive. It demonstrates exactly how an all purpose/supporting set works and where each choice you have within the moveset is. It would only diminish the quality overall, in my opinion, to break it down into two sets.

Implemented both QC checks, thank you! This is now ready for GP.

Crunch is a reliable STAB attack, which maims Pokemon like Starmie, Rotom-A, Celebi, and Latias for tremendous super effective damage. Most foes that it hits neutrally, like Flygon and offensive Suicune, will still sustain quite a bit of damage. Its chance to lower a foe's Defense is also crucial for breaking defensive Pokemon like Zapdos and Clefable. Payback is an alternative to Crunch on much slower variants, as it is more powerful when Tyranitar moves last, (not in a vacuum) but it has less fewer PP and forgoes the chance of a Defense drop. Dark Pulse is another interesting alternative to hit Rotom-A in case of a burn, and it also hits Reflect Starmie for more damage; however, Crunch is almost always better. (Why?)

From there, Tyranitar can use many different moves, which largely to (I think this is what you meant; if I'm wrong, then you can ignore this change) accommodate its team's needs. Fire Blast is a fantastic option to hit Skarmory, Breloom, Scizor, and Bronzong for massive damage. In particular, 2HKOing physically defensive Skarmory makes Tyranitar a potent threat against stall builds. As alternatives, Stealth Rock and Ice Beam are great moves. Tyranitar makes fantastic use of Stealth Rock, as its insanly insanely high Special Defense and solid HP actually make it a check to Starmie, despite its weakness to Water-type attacks. In addition, it can put up sand to disrupt Water-types like Suicune and Kingdra, and with Passho Berry it can serve as a soft check. Having the ability to keep Stealth Rock up versus Starmie is an incredibly desirable trait, as Starmie is terrifying offensively and it's also OU's most consistent spinner by far. Ice Beam surprises foes like Gliscor, Flygon, and Dragon Dance Dragonite with an OHKO; it can also hit physically defensive Zapdos for solid, (RC) (parallelism; there's no comma in "tremendous super effective damage" in the first paragraph) super effective damage.

Tyranitar is the best Pursuit trapper in OU thanks to its high Attack and tremendous bulk. Pursuit decimates Psychic- and Ghost-types like Starmie, Rotom-A, Latias, and Gengar on the switch; it needs to hold a Choice Scarf to reliably trap Gengar, however. Tyranitar can also use Pursuit to wear down foes as they switch out, like Clefable, Zapdos, and even Jolteon, Suicune, and Draco Meteor-locked Kingdra. For some teams, however, the threat of Pursuit is enough, and it Tyranitar can use moves like Fire Blast and Ice Beam in its place to form more dedicated mixed attacking sets.

Stone Edge is Tyranitar's most powerful STAB attack, which hits Gyarados, Dragonite, Zapdos, and Togekiss super effectively. It can also be used to fish for a critical hit against bulkier Pokemon like Clefable, Suicune, and Blissey. Earthquake is a great alternative to reliably cover Nidoqueen, Heatran, Magnezone, Infernape, Calm Mind Jirachi, and Lucario. As a bonus, it can hit Zapdos as it uses Roost, which surprisingly makes a large difference in the matchup. It may be just as effective to use a combination of, say, moves like Crunch and + (If you're using the moves in this order, make this change. Otherwise, no change needed, though I presume this is the correct order due to Zapdos using Roost) Earthquake versus Zapdos as it is to use Stone Edge, as the latter only has 8 eight PP, meaning it Tyranitar can only use the move four times due to Zapdos's ability Pressure. This means that Zapdos may be able to use Roost in succession to reduce Stone Edge's PP. Superpower hits Heatran, opposing Tyranitar, and Lucario for massive damage; it also hits Clefable and Blissey super effectively, often OHKOing the former and coming very close to OHKOing the latter. Using Superpower will make Tyranitar worse off versus Zapdos, however, so it may want to run Ice Beam alongside it.

Set Details
========

It's extremely important to note that this Tyranitar set can and should (It can't run multiple EV spreads at once!) run a large number of viable EV spreads. Depending on the moveset, it may want more or less Special Attack investment, more Special Defense investment, or even more Speed. The above EV spread has an emphasis on Special Defense, which it Tyranitar uses to even further strengthen its effectiveness versus a large variety of special attackers, like Zapdos, Rotom-A, Latias, Starmie, Heatran, Kingdra, and Suicune. 52 Special Attack EVs allow Fire Blast to OHKO uninvested Breloom and significantly improve its improves the move's damage output versus Skarmory. 80 Speed enables it EVs enable Tyranitar to outpace uninvested Skarmory; however, if you use Fire Blast, you may want to invest more Speed at the expense of Attack or Special Defense to let Tyranitar outpace faster Skarmory, Breloom, and Scizor. The rest of the EVs are invested into Attack to maximize it given the constraints. If you use Ice Beam and Fire Blast, you may want to invest a bit more EVs in Special Attack to allow Tyranitar to shut down Skarmory and Gliscor more effectively.

Passho Berry is what largely enables Tyranitar to turn the tide on all Water-types. There is not a single unboosted Water-type move that OHKOes Tyranitar——not even +1 Gyarados's Waterfall or Choice Band Swampert's Waterfall with a Torrent boost when opting for a Lonely nature. (It's wordy, but it's also less of a mouthful than "Lonely Choice Band Swampert's Torrent-boosted Waterfall". I'll let this slide) This item is especially effective versus Rain Dance sweepers like Kingdra and Ludicolo, as it Tyranitar can come in on a Hydro Pump, set up sand, and still be relatively healthy. Alternatively, Custap Berry takes advantage of Tyranitar's tremendous bulk, which often enables it to survive two attacks and be within Custap Berry's activation range. This can give it an extra chance to attack or set up Stealth Rock, which Passho Berry often doesn't have do. Alternative items like Lum Berry and Chople Berry can be used as well. Lum Berry can help Tyranitar to beat Will-O-Wisp Rotom-A, and Chople Berry can be used for Mach Punch Breloom and, more importantly, Focus Blast Gengar. It can often be difficult to justify these options over Passho Berry and Custap Berry, however, as Will-O-Wisp Rotom-A can miss with Will-O-Wisp and often still loses to Tyranitar, (If non-Will-O-Wisp sets can beat Tyranitar, then we might have to do some reworking here) and Choice Scarf (Didn't see this coming; why is Choice Scarf mentioned here?) Tyranitar is more reliable versus Gengar.

The choice between a Lonely, Adamant, and Brave nature is mostly set-dependent. If you're using Fire Blast without Ice Beam, you may want to invest more Speed while not lowering your Tyranitar's Special Attack with an Adamant nature, so a Lonely nature fits best in these situations. An Adamant nature is best when you don't opt for any special attacks, such as with attacks—a moveset like Stealth Rock / Pursuit / Crunch / Earthquake. A Brave nature is a decent alternative to Lonely nature, reducing its Tyranitar's Speed rather than Defense, which is often a good choice; however, a Lonely nature allows Tyranitar to just barely outspeed Clefable, which can be quite significant depending on the team.

Usage Tips
========

Switch Tyranitar in on special attackers like Zapdos, Rotom-A, and Latias. When facing Water-type special attackers like Starmie, Kingdra, and Suicune, try to pivot into a Water-resistant teammate before switching into Tyranitar so there's less likelihood of Tyranitar sustaining a Water-type attack as it switches in. If you're using a less expected move like Ice Beam or Fire Blast, keep it concealed until you lure Tyranitar lures the right target in, like Skarmory and or Gliscor. If you notice that Rotom-A has Leftovers, it almost certainly has Will-O-Wisp, so try to play around that by switching into a Fire-type Pokemon or a burn absorber like Clefable, Blissey, or Roserade. When you are sure your foe will switch out, Pursuit is very often a great option to wear it down, even against Dark-resistant Pokemon like Heatran and Magnezone.

If you're using a Custap Berry, pay close attention to Tyranitar's HP as it gets lower. Be cognizant of entry hazards and how much HP Tyranitar will have after sustaining damage from Stealth Rock and Spikes. Doing so potentially enables Tyranitar to use its Custap Berry after switching in when it wasn't able to prior. Try to familiarize yourself with how much damage Tyranitar takes from an opposing Pokemon's attack to open up the potential for long-(AH)term planning with Custap Berry's activation in mind.

Tyranitar is the quintessential Pokemon that supports all of its teammates rather than the other way around, and it fits on almost any team. However, there are a few Pokemon that work well to support any set this Tyranitar can run. Infernape and Heatran can switch into Will-O-Wisp. Their devastating Fire-type attacks melt Steel-types like Metagross, Bronzong, Jirachi, and Lucario, which all give Tyranitar trouble. Both can also use Grass coverage to wear down bulky Water- and Ground-types like Swampert, Milotic, Hippowdon, and Suicune. Choice Band Infernape can lure in Starmie, Rotom-A, and Latias and use U-turn to get Tyranitar in freely. Heatran can use Magma Storm to trap, cripple, and even remove foes like Swampert, Milotic, and Zapdos. Gyarados often switches into Infernape and Heatran and sustains significant damage from powerful Fire-type attacks, which helps Tyranitar. (What exactly are you saying here? Are you saying that Infernape and Heatran can weaken Gyarados and allow Tyranitar to pick it off, type matchups be damned?) In turn return, ("in turn" = "in succession" or "as a result"; it is not a synonym for "in return") Tyranitar can trap and remove Starmie, Choice Scarf Rotom-A, and Latias for Infernape and Heatran, as well as wear down Zapdos and Flygon. Its ability Sand Stream helps keep Suicune, Zapdos, Gyarados, and Milotic in check by interfering with their Leftovers recovery, which Infernape and Heatran appreciate. Gyarados is a great teammate for Tyranitar as well, as it can switch into Earthquake from the likes of Swampert and Flygon and boost its Attack and Speed with Dragon Dance, setting up for a sweep. Tyranitar wears down Zapdos for Gyarados, and checks Choice Scarf Rotom-A, Latias, Choice Scarf Heatran, and Starmie for Gyarados. (This change was to help with the phrasing; I presume that wearing down these foes help Gyarados too, right? I assume so because you mentioned them here, but if I'm wrong, please let me know.) A Starmie of your own can spin entry hazards away to help keep Tyranitar and Flying-types healthy. Starmie also checks Infernape, Water-types, and Ground-types. Zapdos can spread paralysis with Discharge, switch into Fighting- and Ground-type attacks, and threaten bulky Water-types, all of which makes Tyranitar more threatening. Tyranitar's 4x Fighting-type weakness means that Fighting-immune Pokemon like Gengar and Rotom-A pair quite well to ward off most Fighting-types. Latias resists Fighting-, Water-, and Grass-type attacks, (AC) while Tyranitar resists Ghost- and Dark-type attacks. Magnezone's support ability to trap Skarmory and Scizor enables Tyranitar to drop Fire Blast for Stealth Rock more easily. Jirachi can support Tyranitar in various ways, whether it paralyzes foes with Body Slam, lures in and removes Tyranitar's checks with coverage moves like Grass Knot and Thunderbolt, or wears down the opposing team with an Iron Head barrage.

Moves
========

Behold, OU's most defining set. Tyranitar's impeccable stats, unique typing, monstrous Special Defense in sand, and vast movepool enable it to fulfill many different roles simultaneously. Crunch is a reliable STAB attack, which maims Pokemon like Starmie, Rotom-A, Celebi, and Latias for tremendous super effective damage. Most foes that it hits neutrally, like Flygon and offensive Suicune, will still sustain quite a bit of damage. Its chance to lower a foe's Defense is also crucial for breaking defensive Pokemon like Zapdos and Clefable. Payback is an alternative to Crunch on much slower variants, as it is more powerful when Tyranitar moves last, (not in a vacuum) but it has less fewer PP and forgoes the chance of a Defense drop. Dark Pulse is another interesting alternative to hit Rotom-A in case of a burn, and it also hits Reflect Starmie for more damage; however, Crunch is almost always better. (Why?)

From there, Tyranitar can use many different moves, which largely to (I think this is what you meant; if I'm wrong, then you can ignore this change) accommodate its team's needs. Fire Blast is a fantastic option to hit Skarmory, Breloom, Scizor, and Bronzong for massive damage. In particular, 2HKOing physically defensive Skarmory makes Tyranitar a potent threat against stall builds. As alternatives, Stealth Rock and Ice Beam are great moves. Tyranitar makes fantastic use of Stealth Rock, as its insanly insanely high Special Defense and solid HP actually make it a check to Starmie, despite its weakness to Water-type attacks. In addition, it can put up sand to disrupt Water-types like Suicune and Kingdra, and with Passho Berry it can serve as a soft check. Having the ability to keep Stealth Rock up versus Starmie is an incredibly desirable trait, as Starmie is terrifying offensively and it's also OU's most consistent spinner by far. Ice Beam surprises foes like Gliscor, Flygon, and Dragon Dance Dragonite with an OHKO; it can also hit physically defensive Zapdos for solid, (RC) (parallelism; there's no comma in "tremendous super effective damage" in the first paragraph) super effective damage.

Tyranitar is the best Pursuit trapper in OU thanks to its high Attack and tremendous bulk. Pursuit decimates Psychic- and Ghost-types like Starmie, Rotom-A, Latias, and Gengar on the switch; it needs to hold a Choice Scarf to reliably trap Gengar, however. Tyranitar can also use Pursuit to wear down foes as they switch out, like Clefable, Zapdos, and even Jolteon, Suicune, and Draco Meteor-locked Kingdra. For some teams, however, the threat of Pursuit is enough, and it Tyranitar can use moves like Fire Blast and Ice Beam in its place to form more dedicated mixed attacking sets.

Stone Edge is Tyranitar's most powerful STAB attack, which hits Gyarados, Dragonite, Zapdos, and Togekiss super effectively. It can also be used to fish for a critical hit against bulkier Pokemon like Clefable, Suicune, and Blissey. Earthquake is a great alternative to reliably cover Nidoqueen, Heatran, Magnezone, Infernape, Calm Mind Jirachi, and Lucario. As a bonus, it can hit Zapdos as it uses Roost, which surprisingly makes a large difference in the matchup. It may be just as effective to use a combination of, say, moves like Crunch and + (If you're using the moves in this order, make this change. Otherwise, no change needed, though I presume this is the correct order due to Zapdos using Roost) Earthquake versus Zapdos as it is to use Stone Edge, as the latter only has 8 eight PP, meaning it Tyranitar can only use the move four times due to Zapdos's ability Pressure. This means that Zapdos may be able to use Roost in succession to reduce Stone Edge's PP. Superpower hits Heatran, opposing Tyranitar, and Lucario for massive damage; it also hits Clefable and Blissey super effectively, often OHKOing the former and coming very close to OHKOing the latter. Using Superpower will make Tyranitar worse off versus Zapdos, however, so it may want to run Ice Beam alongside it.

Set Details
========

It's extremely important to note that this Tyranitar set can and should (It can't run multiple EV spreads at once!) run a large number of viable EV spreads. Depending on the moveset, it may want more or less Special Attack investment, more Special Defense investment, or even more Speed. The above EV spread has an emphasis on Special Defense, which it Tyranitar uses to even further strengthen its effectiveness versus a large variety of special attackers, like Zapdos, Rotom-A, Latias, Starmie, Heatran, Kingdra, and Suicune. 52 Special Attack EVs allow Fire Blast to OHKO uninvested Breloom and significantly improve its improves the move's damage output versus Skarmory. 80 Speed enables it EVs enable Tyranitar to outpace uninvested Skarmory; however, if you use Fire Blast, you may want to invest more Speed at the expense of Attack or Special Defense to let Tyranitar outpace faster Skarmory, Breloom, and Scizor. The rest of the EVs are invested into Attack to maximize it given the constraints. If you use Ice Beam and Fire Blast, you may want to invest a bit more EVs in Special Attack to allow Tyranitar to shut down Skarmory and Gliscor more effectively.

Passho Berry is what largely enables Tyranitar to turn the tide on all Water-types. There is not a single unboosted Water-type move that OHKOes Tyranitar——not even +1 Gyarados's Waterfall or Choice Band Swampert's Waterfall with a Torrent boost when opting for a Lonely nature. (It's wordy, but it's also less of a mouthful than "Lonely Choice Band Swampert's Torrent-boosted Waterfall". I'll let this slide) This item is especially effective versus Rain Dance sweepers like Kingdra and Ludicolo, as it Tyranitar can come in on a Hydro Pump, set up sand, and still be relatively healthy. Alternatively, Custap Berry takes advantage of Tyranitar's tremendous bulk, which often enables it to survive two attacks and be within Custap Berry's activation range. This can give it an extra chance to attack or set up Stealth Rock, which Passho Berry often doesn't have do. Alternative items like Lum Berry and Chople Berry can be used as well. Lum Berry can help Tyranitar to beat Will-O-Wisp Rotom-A, and Chople Berry can be used for Mach Punch Breloom and, more importantly, Focus Blast Gengar. It can often be difficult to justify these options over Passho Berry and Custap Berry, however, as Will-O-Wisp Rotom-A can miss with Will-O-Wisp and often still loses to Tyranitar, (If non-Will-O-Wisp sets can beat Tyranitar, then we might have to do some reworking here) and Choice Scarf (Didn't see this coming; why is Choice Scarf mentioned here?) Tyranitar is more reliable versus Gengar.

The choice between a Lonely, Adamant, and Brave nature is mostly set-dependent. If you're using Fire Blast without Ice Beam, you may want to invest more Speed while not lowering your Tyranitar's Special Attack with an Adamant nature, so a Lonely nature fits best in these situations. An Adamant nature is best when you don't opt for any special attacks, such as with attacks—a moveset like Stealth Rock / Pursuit / Crunch / Earthquake. A Brave nature is a decent alternative to Lonely nature, reducing its Tyranitar's Speed rather than Defense, which is often a good choice; however, a Lonely nature allows Tyranitar to just barely outspeed Clefable, which can be quite significant depending on the team.

Usage Tips
========

Switch Tyranitar in on special attackers like Zapdos, Rotom-A, and Latias. When facing Water-type special attackers like Starmie, Kingdra, and Suicune, try to pivot into a Water-resistant teammate before switching into Tyranitar so there's less likelihood of Tyranitar sustaining a Water-type attack as it switches in. If you're using a less expected move like Ice Beam or Fire Blast, keep it concealed until you lure Tyranitar lures the right target in, like Skarmory and or Gliscor. If you notice that Rotom-A has Leftovers, it almost certainly has Will-O-Wisp, so try to play around that by switching into a Fire-type Pokemon or a burn absorber like Clefable, Blissey, or Roserade. When you are sure your foe will switch out, Pursuit is very often a great option to wear it down, even against Dark-resistant Pokemon like Heatran and Magnezone.

If you're using a Custap Berry, pay close attention to Tyranitar's HP as it gets lower. Be cognizant of entry hazards and how much HP Tyranitar will have after sustaining damage from Stealth Rock and Spikes. Doing so potentially enables Tyranitar to use its Custap Berry after switching in when it wasn't able to prior. Try to familiarize yourself with how much damage Tyranitar takes from an opposing Pokemon's attack to open up the potential for long-(AH)term planning with Custap Berry's activation in mind.
