Kirby

Kirby began his life as a placeholder character sprited by none other than Masahiro Sakurai himself. He is believed to be living in a small round house in Vegetable Valley, a division of Green Greens.

As always, he is famous for his endless appetite for food(and everything else) and his copy abilities. According to Squeak Squad, lately his gluttony seems to be so bad that he can't take having one piece of food being stolen. His wrath for stealing a strawberry shortcake is terrifying.

Nintendo seems to have a thing for not having their protagonists talk. The same applies to KCCh as well, as Kirby only will communicate through gestures. I do agree characters like him shouldn't talk; It'll ruin his image for many if he did.
