A little idea I have is that depending on the universe Kirby is in, his appearance changes to fit that universe. And with the change, Kirby gets a new gimmick and maybe possibly the genre of the game gets changed. For example. For the Hollow Kirby one, the genre of the game would be a Metroidvania + Platformer. Here is a list for the gimicks: 1. Normal Kirby Style 2. Can fold into different things (kinda like TTYD) 3. Turn-Based stuff 4. Can Build stuff with resources Kirby inhales 5. Can throw pikmin and gain abilities to power up the pikmin 6. Metroidvania 7. Undertale-like battles. 8. Final Boss
