Adam is a minor kid in Uncle Grandpa. He first appeared in "Belly Bros" when Belly Bag was telling Belly what Uncle Grandpa is. He officially first appeared in "Brain Game", he needed Uncle Grandpa and Pizza Steve's help beating a video game that he could not beat. He is voiced by Dee Bradly Baker.
He has black hair, black/brown/green eyes, teeth from the top sticking out of his mouth, red shirt, dark blue pants and black shoes.
He's a kind of person that gets hooked on a video game and will not stop playing until he beats it.
