Kerash.

His mysterious origin lying in the deepest reaches of space, this valiant jade-titan has come to protect us and the small fuzzy critters that reside here from the wrath of the evil beasts that want to do us harm. He is Kerash, the almighty Dimension Warrior!

Based on giant Japanese super heroes like Ultraman, I present to you one of the great protectors of my own fanmade Kaiju-verse.
