What is the most impressive psychic Pokemon that you have seen in the anime?
You're asking me to recall stuff I haven't seen in like, 5+ years.. lol. Well, Mewtwo was absurdly powerful in the first movie. Not only could he fight one on one like any other Pokemon, he also had the intelligence to create his island, amass all those devices to clone Pokemon, create that storm, and brain wash Nurse Joy. :O Mew had some impressive moves one normally wouldn't imagine if just playing the games, too. Bubbles. <3
Hmm, the Unown in their movie could also do a lot more than they can in the games.
Oh oh! I think in one of the Battle Frontier episodes, Anabel could telepathically communicate with her Pokemon. Just how awesome would that be. >.<
