I'm not a Kirby fan. All the characters he created that anyone can remember actually having a personality of any kind, he developed with someone else. Kirby tossed out the character designs and maybe some basic situations/motivations, then Stan made them relatable.

When role-playing games came along in the 1970's, there were many thousands of kids who were engaged in the same level of "creating" that Kirby did, which is why I pay attention to Kirby's relative drawing abilities more than his rearranging costume elements and coming up with dopey names.
