Originally a robotic &#039;space cop&#039;, Junk&#039;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&#039;s strength even further, adding new weapons to his arsenal. While his name is unknown, Sadamitsu refers to him as &#039;Junk&#039; while other characters refer to him as &#039;Helmet&#039;, &#039;Helmet-san&#039; (Mr. Helmet) and the like. Voiced by: Kazuhiro Yamaji (Japanese), Sean Schemmel (English)    

Sadamitsu, a high-school delinguents turned to a masked-hero, while not dealing with his rocky relationship with the strong female protagonist, he puts on a motorcycle-helmet-like mask and becomes a semi-robotic superhero who fights. He is assisted by other possibly- mechanical creatures in order to save the earth from the invasion of 20,000,000 escaped alien convicts.<br><br>
