Hmm... an interesting thought, that. Who shall we test this idea on, then? After all, it's for science!
...from the sounds of it, you're still confused. =P
It's kinda neat that Game Freak kept/keep on reusing some stuff from an old game they made before in Pokemon. And Volt Tackle is a nice move (especially in Brawl XD), although I don't have too much interest for what I have dubbed the 'Cancer Pichu'. It's interesting, but...meh. Not unexpected from me that it knows that - but Pain Split? XD
