In episode 38, it was used by Dragonoid Colossus along with Beamblitzer, Blasteroid, and Nukix Gear. It is now presumed destroyed along with Dragonoid Colossus.
Unlike the other pieces, this one can only be put on after Dragonoid Colossus is completely open, as it usually goes on the neck. It looks like a pair of swords or switchblades. It is Silver and has 80 Gs.
