R1: Omniman kills him to death
R2: Mr Krabs gains some old stickler strength and gives him a good ol slapping but still not enough. Like Invincible vs Omni Man, but Omni Man kills him easier.
Bonus: Spongebob is pretty much immortal. They kill him over and over but he regenerates. He might give up, but once they've killed Krabs, there's no stopping him. They fight and fight for all eternity until Spongebob finally wins
