Obviously Kirby is the best fighter. Meta Knight's pretty good too, but Kirby seems to fight better, even if Meta Knigh helps a little.
lol, Dedede best fighter. XD He doesn't even fight. He's just like "I'm going to order a demon beast and not pay for it because I'm to lazy". It's funny, really.
Return to Dreamland, Mass Attack, and Air Ride are the best Kirby games. In no particular order.
Best Hoshi no Kirby characters:
4. Meta Knight
5. Customer Service.
