Prince Huge appears to be a huge and buff man similar to Muscle Prince who wears a dark pink lute suit, an odd shade of blue jester shoes, a crown and a short cane. Also, his skin color is gray, and he has short black hair.
Prince Huge is a friendly, polite, and respectful person. He thanks Finn after Finn kisses him to restore him to his natural form, acknowledging that he does not "know a lot of dudes who'd do that to help a guy out," to which Finn replies, "whatevs." He respects Finn for doing this for him. The prince appears to have a cheerful and jolly disposition. He prides himself on his attractiveness, jubilantly hollering "I'm HOT again!" after Finn transforms him back into his normal body.
- Not counting Neptr, Prince Huge is the first prince to have appeared in the show who is not a gender-swap of a princess until the episode "Jake Suit," because of the appearances of Flame Princess' older brother and her two younger siblings.
- It is confirmed by Steve Wolfhard that he is related to Huge King, who appears in "Walnuts & Rain."
