Eggyhead, the character in the picture (if that wasn't obvious), is not actually a beanoid, rather he comes from an alien race of Eggs, but they all died out after a war thingy.
Eggyhead was the only survivor because of literal divine intervention. He lived because God decided he would be important.
He's 200 years old but is pretty young and immature due to his biology and the fact he lost all forms of parenting at a young age. He's also just autistic.
He has superhuman abilities but barely uses them because he doesn't really fight anyone.
