Junk ポンコツ

Originally a robotic 'space cop', Junk's body was destroyed during an encounter with a Rukeitai. His severed head called out to Sadamitsu and, once worn as a helmet, empowered the youth enough to stand up to the superhuman strength of the Rukeitai. While severely damaged towards the end of the anime, upon his revival he increases Sadamitsu's strength even further, adding new weapons to his arsenal. While his name is unknown, Sadamitsu refers to him as 'Junk' while other characters refer to him as 'Helmet', 'Helmet-san' (Mr. Helmet) and the like.
