The Yellow Sun God

This is our sun. Well, really he's The Immortals' sun, but they live on Fantasy Earth and we live on Earth Earth so they get Fantasy Sun, which is this guy.

Birth of the Sun God
During The Egg War, the Cosmic Space Gorilla destroys The Black Egg and is consumed by The Evil within. He is driven mad and wreaks havoc across the young universe. The fires set by his rampage incubate The White Egg and The Yellow Sun God is born. He fights off the forces of evil and brings peace back to the universe. During his fight with evil, a sun beam goes astray and strikes The Grey Egg, chipping off a piece. This piece is imbued with The Sun's Light and The Moon Goddess is born..
