Gnash is a muscular, friendly shark-reptile Humanoid hybrid with vibrant green skin and a hyper-defined, "bouncy" physique. His broad frame features massive pecs and a deep six-pack, topped with a round head, wide cartoon eyes, and rows of sharp teeth. Despite his fearsome jaw, he radiates a Friendly "himbo" energy. He wears a dark green sports crop top, black athletic shorts, and thick red wristbands. Standing in confident, powerful poses, his exaggerated silhouette is clean, bold, and heroic.
