Dharkon

Dharkon, the lord of darkness, is one of the two main antagonists of Super Smash Bros. Ultimate’s story mode, World of Light, where he sought to create a new world by destroying the old one's inhabitants and creating spirit possessed puppet fighters of the fighters in Super Smash Bros. He leads an army of Crazy Hands which destroy the Master Hands, after Dharkon emerges. Dharkon appears after you defeat Galeem as the main boss of the World of Dark.

Physical Appearance
Dharkon is the dark version of Galeem, however there are some noticeable differences. Instead of blue, red, yellow, and white, Dharkon is purple and black. While you can't see Galeem's pupils in his eyes, you can see Dharkon's. Also, Galeem has shield-like barriers around his eye, but Dharkon has tentacle/branch-like weapons.
