* Thundurus-T can act as powerful sweeper once it managed to successfully use its setup moves.
* Thundurus-T also has a huge Special Attack Stat and decent offensive typing; it also has impressive coverage, setting it apart from other Electric-types.
* Base 101 Speed is very good, just enough to outspeed the crowded base 100 Speed Tier, not to mention that its typing allows it to resist most common priority attacks.
* The genie has access to two great setup moves in Nasty Plot and Agility.
* Volt Absorb sets Thundurus-T apart from opposing Electric-types and allows Thundurus-T to soft check many of them, namely Magnezone, Rotom-W, and Thundurus. Tapu Koko also needs use Hidden Power Ice to damage Thundurus-T.
* However, Thundurus-T is weak to Stealth Rock and has very poor defenses, reducing its abilities to take hits. This is compounded by its vulnerability to residual damage from Life Orb and Stealth Rock and lack of recovery outside from Leftovers or Volt Absorb.
* Thundurus-T is generally passed over for Tapu Koko, Thundurus and even Xurkitree to an extent, however, Thundurus-T's niche over them consist of its sweeping capabilities with Nasty Plot and Agility and overall better coverage.
* Base 101 Speed might be underwhelming when unboosted.
name: Setup Sweeper
move 1: Agility
move 2: Thunderbolt
move 3: Hidden Power Ice
move 4: Nasty Plot / Focus Blast
ability: Volt Absorb
evs: 252 SpA / 4 SpD / 252 Spe
* Agility allows Thundurus to hit a very scary Speed tier. Outspeeding the entire unboosted metagame and anything up to maximum Speed Choice Scarf Tapu Koko and +1 maximum Speed Pheromosa.
* Thunderbolt is Thundurus-T's main STAB move, and due to Thundurus-T’s massive Special Attack Stat, it hits very hard.
* Hidden Power Ice forms BoltBeam coverage with Thunderbolt and allows Thundurus-T to break through Landorus-T, Zygarde, and Garchomp.
* Nasty Plot boosts Thundurus-T’s Special Attack to outstanding levels. It also allows Thundurus-T to wallbreak more consistently, since without a boosting move Thundurus-T will most likely still get walled by dedicated special walls.
* Alternatively, Focus Blast allows Thundurus-T to hit Steel-types, Ferrothorn and Heatran are examples of Pokemon that hate this move, and both wouldn't take too much from uninvested Thunderbolt or HP Ice.
* Timid is the preferred nature as it allows Thundurus-T to outspeed +1 maximum speed Pheromosa, and in case Thundurus-T can't afford to set up an Agility, it will still outspeed anything up to maximum Speed base 100s such as Mega Charizard Y and Manaphy.
* Modest could be run for more power, but the extra Speed is very important for Thundurus-T.
* The Speed EVs allows Thundurus-T to go as fast as possible.
* The Special Attack EVs further increase Thundurus-T’s power.
* Leftovers increases Thundurus-T's longevity and allows it to be less vulnerable to passive damage.
* Life Orb could be used for extra power, but the passive damage makes Thundurus-T easier to wear down.
* Thundurus-T works best as a late-game cleaner as it can set up on Pokemon like Magnezone, Celesteela, Skarmory and Tapu Koko.
* It’s important to keep in mind that counter to Thundurus-T, such as Mega Venusaur, Swampert, Seismitoad, Quagsire, and Gastrodon, need to be removed before it attempts to sweep.
* On sets with both Nasty Plot and Agility, its not necessary to set up both for sweeping, and it heavily depends on your opponent's team. Agility is more recommended for being used on faster and frailer teams, mainly hyper offense; Nasty Plot, on the other hand, sees more use on slower and bulkier teams, such as stall teams.
* Use Volt Absorb to your advantage and switch Thundurus-T in on predicted Electric-type moves.
* Thundurus-T heavily appreciates Stealth Rock being removed, so pairing it with a spinner or Defogger is ideal. Examples includes Latios, Excadrill, Skarmory, and Tapu Fini.
* Physical wallbreakers that can reliably check Chansey, such as Buzzwole, Mega Scizor, and Alolan Marowak can be great partners.
* Teammates that can threaten bulky Ground-types are great partners too; Pokemon that can perform this role well include Serperior, Tapu Bulu, Keldeo, and Tapu Fini.
* Flying-types can help Thundurus-T get past bulky Grass-types, Pokemon that can do this job include Mega Pinsir and Tornadus-T, and Landorus-T and Salamence can also KO most Grass-types with their Supersonic Skystrike. Bulkier Steel-types can also help against bulkier Grass-types; good options include Mega Metagross, Mega Scizor and Magearna.
* Pelipper can set up rain with its ability Drizzle and allow Thundurus-T to run viably Thunder, which is significantly stronger than Thunderbolt. It can also provide a slow U-turn and remove Stealth Rocks from your side of the field with Defog.
* Dugtrio can trap Tyranitar, which is a huge threat to Thundurus-T thanks to its massive Special Defense under sand. It also helps to eliminate Chansey, another thorn in Thundurus-T's side.
* An all-out attacking set with Volt Switch, Hidden Power Ice, Focus Blast, and Sludge Wave or Grass Knot could work, but other fast Electric-types, such as Tapu Koko and Thundurus, tend to outclass Thundurus-T on this role. The same could be said for a Choiced set, Choice Specs provides immediate power whereas Choice Scarf allows Thundurus-T to reach an impressive Speed tier with no set-up, but both sets are prediction reliant and still are outclassed.
* Expert Belt might be a useful alternative to Life Orb to reduce passive damage, but it severely weakens Thundurus-T’s non-super effective moves and doesn’t provide the utility Leftovers does.
* Yache Berry might allow Thundurus-T to take an Ice Shard and keep its sweep going, or maybe set up on a weaker Ice-type, but this option reduces Thundurus-T’s damage output or forces to give up passive recovery in Leftovers.
* Hidden Power Flying can actually give Thundurus-T a Flying STAB attack, which would allow it to break through Grass-types and Alolan Marowak more consistently; however, using Hidden Power Flying over Hidden Power Ice means that most Ground-types will be tanking your hits unless you're running Grass Knot.
* The combination of Flyinium Z and Fly can provide a one-time powerful Flying move coming off Thundurus-T’s average base 105 Attack stat, which can KO defensive Mega Venusaur with some prior damage, but it is generally unreliable and requires a Hasty or Naive Nature to work.
* Knock Off is good for utility and also damages Latios and Latias, but it is usually a waste of a moveslot.
Checks and Counters
**Bulky Ground-types**: Ground-types are immune to Thundurus-T's Electric STAB and require prediction to hit with Hidden Power Ice. Futhermore, Gastrodon and Hippowdon can stomach an Hidden Power Ice, and both wall any set without Grass Knot.
**Bulky Grass-types**: Grass-types resist Thundurus-T's main STAB move and tend to take little from unboosted Hidden Power Ice, due to its low Base Power. Pokemon like Mega Venusaur are especially annoying because of Thick Fat halving Hidden Power Ice's damage output. On sets without Focus Blast, Ferrothorn can be huge threat too, and Assault Vest Tangrowth can also be quite annoying if Thundurus-T isn't packing Sludge Wave.
**Chansey**: Chansey outright walls Thundurus-T. Unless you’re running a set with both Nasty Plot and Focus Blast, Chansey will always be able to bet Thundurus-T one-on-one with the combination of Soft-Boiled and Seismic Toss.
**Alolan Marowak**: Alolan Marowak is immune to Thunderbolt and takes unnoticeable damage from Hidden Power Ice. Furthermore, Thundurus-T takes a ton of damage from Alolan Marowak's Shadow Bone or Fire Punch.
