I dunno... Metal Sonic's copy ability would probably give him the same deal in a fight against said Iron Giant. Which was the point I was making. If the copy ability works as I believe it does, he'd be truly unstoppable if he were to copy someone or something really dangerous. Like the Iron Giant, The Incredible Hulk, or Unicron.

I got into an argument with someone about the last one, by the way. We agreed that they'd be fighting to a standstill if they actually did battle.
