My thoughts (although I haven't actually played PBR yet...):
Go hula-hooping Charmander! Lol...
Metapod - darn faker! You're just too lazy to fight!
Lol - the Pidgeot family sure knows how to overdramatize things! They could be actors one day...
Poor Pikachu - you just KNOW it has willpower, but it's too weak to fight... I think that's the saddest one to watch... (actually, it's especially sad to watch all the little Pokemon faint... :()
Poor Raichu; looks like it's choking last second...
Serves Jigglypuff right to get deflated upon fainting with such a quirky animation. That thing is downright ANNOYING in Super Smash Brothers (64, Melee, and Brawl).
I love how Vileplume deflates; hearkens back to Pokemon Stadium 2 when I first saw it...
Meowth's is hilarious!
Machamp: "Wa! Ga! NOOOOOOOOOO!" Lol
Weepingbell's eyes are creepy yet funny...
Poliwhirl gets in a little spin before fainting...
Geodude is all like "What is this feeling? It is strange; I can't comprehend it...!"
Abra either violently shaking or dancing very badly while levitating. Either way, it looks funny.
Kadabra falls down, looks like it's pooping, throws its spoon in the air, and says "Forget it. DOY...!"
Geez, even fainting takes Slowpoke a while. I love its look of strained comprehension; I bet it realizes it fainted a few minutes after it get backs in the Pokeball...!
Slowbro's all like "What do I do, master?" then looks like it got stabbed from behind by a sneak attack...
Magnemite and Magneton's fainting animations look cool, like you just broke an expensive piece of electronics...
Cloyster's all like "WHYYYYYYY?! I wish I hands so I could rip you apart!"
Gengar either looks like it's about to sneeze, or it's like "Ha! Ha! (being cocky) *faints*
OUCH! Onix's head just SLAMMED on the ground. That's got to hurt!
Koffing sputters...
Aww...I liked Jynx's fainting animation better in Pokemon Stadium 2, where its void "collapses" and its clothes clatter on the floor...
Pinsir looks like it's really straining to poop. (And on a side note, those line things on the side of its mouth are the creepiest PBR animations I've seen! It just feels gross looking at those things move... *shudders*)
I like how Dratini straightens out and falls like a board, preserved again from Stadium 2...
LOL at Snorlax's! He gets up, STRUGGLES to inch forward a few feet, becomes wide-eyed, and is like "WHEW! Well, that's all the exercise I'm getting today!"
