Barnaby is a stoic, handsome rookie hero forced to partner with Kotetsu to form the world's first hero team. Motivated by discovering the truth behind his parent's murderer, Barnaby took up his father's name and chose not to adopt a secret identity. He is given the nickname "Bunny" by his new partner, something he does not appreciate.
Barnaby's NEXT power is also Hundred Power, which increases his physical attributes one-hundredfold. However, it only lasts for five minutes, and has a cooldown time of approximately one hour.
