Kirby hasn't changed at all really. He's still a "jolly" fellow. Anyway, he appears sometime in Chapter 3 and somehow ends up stuck with Blaze, Captain N, Cosmo, and Vanilla. Unlike the 4kids craptastic localization of the Kirby anime, Kirby can actually talk and often. He is a slight bit sarcastic here and finds Captain N to be, in his words, a doofus with poo hair.
