Ttar completely dominates 3 gens and is top 7 in the other.
Sleep Talk Vaporeon also hardwalls if Spikes aren't down and is annoying even if they are. Quagsire laughs unless Tar Crunches.GSCTar is the ultimate jack of all trades, master of none. Give him Roar or Curse and he checks Snorlax. Give him Pursuit and he snipes at fleeing foes. Give him DynamicPunch and Snorlax becomes nervous. Give him Fire Blast to roast Skarmory and Exeggutor. Give him Crunch to punish Misdreavus...and so on. Very difficult to switch something not named Machamp or Suicune into Tyranitar, and even then Thunderbolt can deal some damage to Suicune.
ADV and DPP I know about. What's the third gen it "completely dominates"?Ttar completely dominates 3 gens and is top 7 in the other.
I don't know if it completely dominates, but Tyranitar is a really big deal in BW as well. It was actually voted 2nd in the Top 10 Titans of the 5th Gen OU Metagame thing a while back if I remember correctly, and Politoed being voted before it had less to do with Politoed being good and more to do with the fact that Drizzle was so amazing and metagame defining. I'd personally consider Tyranitar to be right up there with Jirachi as one of the best all around Pokemon of BW OU. Jirachee made a good analysis on Tyranitar, so I hate to pretty much repeat what he said, but Tyranitar was a great team player with the various forms of support that it offered. As has been mentioned before, Sand was a valuable form of support in BW1 for things such as Sand Veil users, Excadrill, and even Sand Force Landorus (which was later overshadowed by Sheer Force variants). Even in BW2, Stoutland was a pretty cool Sand abuser, and Sand stall throughout the generation generally just appreciated the extra passive damage which helped to chip away at opponents. Heck, you really didn't need to abuse Sand to take advantage of it. Rain and Sun allowed for a group of very powerful weather-based playstyles, and just having the ability to cancel out the opponent's weather with Sand could ruin your opponent's game plan and turn entire matches around. I often found myself slapping Tyranitar on otherwise completely weather-neutral teams just because it helps in matchups against opposing weather teams. Pursuit is also fantastic. Jirachee already mentioned the Tyranitar + Landorus + Keldeo cores and removing the Lati twins, both of which are notable feats, but it also helped a lot in weather wars as well. For example, max HP Politoed is taking an upwards of ~86% from a Choice Band Pursuit on the switch, which will generally either KO or cause it to die the next time it comes in due to hazard damage and such. It probably goes without saying, but Ninetales doesn't do much better even with significant physical bulk investment. The ability to trap the opponent's weather starter and either KO or weaken them to the point where they won't be able to safely come in and set their weather up anymore is fantastic in a metagame where a solid chunk of teams are running one of Rain or Sun. Tyranitar could also act as a your Stealth Rock user, but I generally preferred to put Stealth Rock on something else. Like BKC mentioned, the lead set seemed to sort of lose its luster near the end of BW, but the specially defensive set could generally find ample opportunities to switch in and set Stealth Rock. Besides the support it offers, Tyranitar also has a nice variety of viable sets such as Choice Band, Choice Scarf, and specially defensive mixed sets. It also just had a great combination of raw power and insane bulk under Sand that made it a great tank in general.ADV and DPP I know about. What's the third gen it "completely dominates"?
Yeah, this. It's one of the better Fires since it has a good Special (only Flareon and Moltres are higher) and a good Speed (tied with Charizard, Rapidash is faster but it sucks) along with Body Slam + Confuse Ray. It's the best anti-lead for Jynx since Charizard's weak to Blizzard and Rapidash sucks (there is also Dodrio but it's also weak to Blizzard). Charizard and Moltres are probably still better though since they both have decent setup options and Ninetales doesn't. Flareon's also competitive with Ninetales outside of the lead spot since it's got fuckoff-huge Attack and Special stats, the same access to Body Slam, and Quick Attack. In reality though you're not going to use any Fires in OU since their STAB burns Starmie and has bad coverage (Steels don't exist yet and all the Ices except Jynx are weak to Electric) and they don't have any good resistances either (Fire doesn't resist Ice yet).Ninetales in RBY OU is an incredibly niche anti lead, as it almost OHKOs Jynx with Fire Blast, and can use CRay T1 to get the extra damage needed. Obviously decent matchup versus Exeggutor too, otherwise nothing to write home about.
The Rocks seen in OU - Rhydon and Golem - are not very effective counters to Fires. They're crippled by burn (and Fire Blast has a 30% burn rate), they're so specially flimsy that they often end up 4HKOed anyway (Moltres can even 3HKO!), and they're slow, which means they can't switch in when they're 2HKOed (which, as I said, is a pretty fair chunk of their health).Ninetales is best RBY OU Fire but that isn't saying much. Since they all get hossed by the Rocks and Waters anyway, Confuse Ray at least gives it the potential to be a huge jerk where Arcanine and friends fail.
Fire Spin's accurate enough if you can spread burns. Which Moltres is pretty good at doing.Well Starmie and Slowbro are the more popular two. Cloyster is ass anyway and doesn't even resist Fire. Even so, Confuse Ray gives Ninetales a valuable tool other Fires don't have to beat these menaces -- hax. Which is the only way you're killing shit in RBY anyway. I don't even like Wrap shit that much in the first place but Fire Spin is too inaccurate, Moltres is a noob.
