What would happen if Kirby ate one of her bombs? Does he get his OG bombs or does he become destroyer of worlds?
Probably bombs. In some of the games like Kirby All-Stars, Kirby gets the basic bomb ability whether he eats a standard bomb enemy or one of the mini-bosses that throws bombs once they're defeated. Any boss or mini-boss he can swallow once defeated always gives whatever power their moveset is closest to in his existing powers.
EDIT: Or rather, that's what Kirby would get if he swallowed Klee. The bombs themselves give no powers (if projectiles can be inhaled at all, you'll just be able to spit it back), you have to swallow the character with the ability to take the ability.
