Jube has black hair with a pointed-up ponytail, much like Ryuma's. He wears a light blue coat with white linings. He wears the standard Foxy Pirates mask and has a light brown vest, a green sash, and dark purple shorts with fur linings. He also has light pink skin.
His fighting style is to primarily tangle with his opponents. He is personally immune to Robin's powers since, being a mollusk fish-man, he does not have an ordinary skeletal system and thus wasn't affected by her Clutch moves.
Attacks
Mucha Karamete (ムチャ絡め手,Mucha Karamete?, literally meaning "Nonsense Entwining Hand"): Jube entangles his opponent with his eight arms to prevent them from moving.
Ikaros Much, another squid fishman, does not bare any resemblance with Jube, except that they both have same amount of arms. This might be due to the fact that Jube is a non-canon character, introduced long before Ikaros was.
