His first look is similar to that of an Incursion but taller and wears glasses. He has a similar build to the Incursion Warrior. The Omnitrix symbol is hidden somewhere on his chest.

His second and main look looks exactly like his first but he wears green glasses and the Omnitrix symbol is located on a green collar on his chest and his clothes consists of green and black colors.

Powers and AbilitiesEdit

He has a long tongue and has enchanced jumping abilities. He also has good hand-to-hand combat skills.
