Little Oars Jr. is an abnormally-large giant, about as large as two full grown giants[4], his nickname coming from the fact that he is still shorter than Oars who was four giants tall. His overall shape and silhouette resembles his ancestor greatly. His skin is yellow-green and he has orange hair reaching down to his legs, which are quite small in comparison to his large belly and hairy forearms. He has large fangs and horns pointing upward, black triangle-like marks just above his eyes, and some stubble on his chin. He also wears three skulls on a beaded necklace rather than a belt, but the most notable item among his effects is a gigantic kasa hat that Ace made for him,[5] which is usually seen resting on his back in a similar fashion to Luffy.
He also sports a black, open indument that looks like a jacket, samurai-like armor plates protecting his chest and back, linked together by chains, and a loincloth with a mimetic pattern on it which looks like the Marine's battleships' hull and which is held up by a fur-lined belt. He carries around a gigantic sword fitting his size, with a large blade and a long hilt.
In the video game One Piece: Gigant Battle!, his color scheme is the same one like his ancestor Oars (this game was developed before Little Oars Jr.' color scheme was revealed in the anime).
