The Rainbow King

The Rainbow King.

The Rainbow King is the king of planet Rainbowl, and is identical to and is obviously a Star World counterpart of King Bob-omb. So far, he has appeared only in the movie The Cosmic Crystals IV: Zythurvia, as a boss in Rainbowl who could only give up a Zyther Crystal in 'tick time', meaning under a time limit. He also has an X counterpart, who makes an appearance in OO12345 and the Dark Star X in which Mario has to fight.
