He appears to be the villain of the story. His body is brown with some visible red highlights. He is said to have nicknames like 'Guardian of Darkness.' Personally, I think he looks cuter than the God Dragon.

A mutant Egg Dragon whose body stopped growing, with only its face, tail, and feet poking out of the shell. He is Nuri's partner. His body is navy blue, and his eggshell is a yellowish-white base with pink spots.
