Squirtle is a nasty good WOPer, but he's basically just an inferior Meta Knight. He really annoys me, I don't know why.. I have trouble countering a good Squirtle, I have little to no experience against certain characters, so.. >.>;
He can be pretty annoying when used right, ofcourse. Any WOPer is a pain in the arse. Oh.. And don't forget about his killer D-throw, the most powerful D-throw in the game.
