Well, this thread looks interesting enough. I'll get the big elephant in the room out of the way first:
Gastly w/Elemental Punches: dafuq?
Gyarados w/Fire Blast: I remember seeing this in Pokemon Stadium as a kid, and I was like "Whaaat? The computer's cheating!" It still makes no sense why he has this. I get that he's somewhat of a dragon, but....he's a water dragon. Like, wth?
Forretress w/Zap Cannon + Volt Switch: How does a metal bagworm generate electricity? Yeah I'm lost here.
