Yuga Khan vs this Demon

Yuga Khan vs this Demon eater...actually Yuga vs Atum the God eater, Demogorge mode...

yeah I jump the waggon.... 😱

Somehow I knew who you meant by "this demon".
Yuga wins.

Yuga Khan escaped from the Source Wall through force of will and uber power. If Atum eats him I'll bet he'll get serious indigestion, assuming he can eat him.
