Grenadier is a destroyer class helix that allows the user to fire off powerful explosions at point blank but needs to fuel it with food for it run properly it uses the iron in the blood to be the catalyst then activates it to cause explosions of various degrees the weakest being a flash bang and the strongest being a low range tactical nuke though the major down side to this helix is that the user is almost constantly eating just to be ready to fight
