Melvin is a character who appeared in the series Uncle Grandpa in the episode "Space Emperor". He is voiced by Jarid Root.
Melvin has blond hair and freckles. He wears a blue shirt with a badge on it, a red towel cape, a cut out cardboard box crown, a pair of clear visors, and shorts with a star pattern on it.
Melvin is very rude, impatient, and demanding when he takes his role as Space Emperor in a game too seriously. He ends up pushing his friends away when he takes his roles too seriously. Later in the Space Emperor episode, he realizes his bossiness annoys people and learns that it is never good to be demanding. After he learns that, he tries to learn to be more generous.
He has a fixation on people making him dinner sandwiches. This must be his favorite food.
This is a error when Uncle Grandpa turns him to normal his hand doesn't have a knife and when he said to his babysitter it's back.
He was featured in the Uncle Grandpa game "Up to Snow Good" on Cartoon Network's official website.
