Long claws on each hand
"Claw" was the codename of a Dark Hunter who was stationed at Xia.
When Blackout, BoM Master and Kakamu attacked the Dark Hunter fleet, Claw tried to fight Kakamu. His ship was shot down by Kakamu, but Claw saved himself by jumping onto the Makuta's Axalara T9, or so he thought, until he was blasted off and fell into the water.
Because the events of the Battle of Xia were erased from history when Blackout rewound time with the Vahi Cube, Claw may not remember participating in the conflict. He could now also be living on the Red Star.
