Under the direction and watchful eye of the manipulating and controlling new superhero called Hard Drive, a bunch of like minded good Samaratins band together to help protect their fellow man through the liberal use of exciting super-powers and heroic secret identities. They call themselves the Young Heroes. Thunderhead, Offramp, and Monstergirl are all old pals. Thunderhead has a crush on Bonfire. Bonfire has the hots for Frostbite, who has the hots for her right back, which would've been great except Hard Drive brainwashed her into going for Thunderhead for a good reason he keeps to himself for now.
Frostbite has a mysterious background.
Hell, they ALL have mysterious backgrounds except Junior, who's just some shrimpy guy with time on his hands.
