Galeem

In Super Smash Bros Ultimate, Galeem is the lord of light in the campaign mode called World Of Light. He is a big light surrounded by rainbow-like feathers and is the arch nemesis of Darkhon, the lord of darkness. Spoiler alert! At the end of the game, they have a big fight at the end, either Darkhon wins, Galeem wins, or they both get defeated to get the TRue ending.
