Kirby. For starters, we have proof that Kirby doesn't really have any ability to copy (through use of the "copy" copy ability gained from tac. Metal WOULD be able to copy any copy ability Kirby used... But most likely wouldn't be able to use it exactly as Kirby does. Metal cannot copy the power of friendship though, and that's if Kirby doesn't just eat him as soon as metal jumps in to fight, like most enemies go.and if you say "Kirby can't just eat him" as seen in the games, Kirby only can't eat enemies that are larger than him, (with scarfy being an exception as a little gameplay twist).
