here's a tip for when playing Cartoon Network's TKO game: use either Duncan or Armodrillo. all you have to do is go > > Z or X for most of the round (and never stop) and you win. that move for them is a ground pound that -for Armodrillo- will cause a metal spike or -for Duncan- spikes of earth to come up under your opponent. i find that a very interesting thing a human can do (it's like something an Earthbender does...) but i'm not really complaining.
oh, and Chef isn't that great in my opinion. the strongest move of his is his special move, throwing a giant sink.
Edit: ok, Chef's ok, Johnny Test's attacks are a little weak.
