No. 1 Kabutack (カブタック Kabutakku): The first B-robot and the prototype model, built with a rhinoceros beetle-like appearance and a biochip based on the insect. Being the protoype, his Super Mode can only last for 3 minutes. In Super Mode, he wields a weapon called Shock Stick (ビリットスティック Biritto Sutikku), which is transformed from his helmet in "normal mode". He needs Yuzuru's Friendship Commander, a comm-link-like device, to transform into Super Mode.
