Arcues and Kyogre come close
Kyogre seems kind of random, is it due to the whole "Rain Pokemon are overpowered" thing?
Kyorge can 2HKO Chansey, unless you are running Groundon or maybe sand in Ubers, there is no reason not to use it.
Normal Arcues is crazy dangerous.
Still, though, Mewtwo
You know, I have been playing a bit of RBY Ubers lately, and honestly I am starting to think RBY Mewtwo is a bit to hyped. Sure it is easily one of the most devastating set up sweepers ever, but IMO it suffers a big problem: It can't beat its self. If a Mewtwo attempts to set up on something of mine, I can switch into my own Mewtwo and Amnesia up, causing a stalemate situation until one Mewtwo freezes the other. This does not happen with other Pokemon, after a swords dance Arcues-N devastates a switched in opposing arcues-n with Extreme Speed, can story with Kyorge but with Thunder.
nice joke man
I feel like we've been over this, Charizard is simply the shit.
Ok I'm gonna leave your serious PKmN thread now. Sorry Kirbx.
better be, Charizard nub
