Natsuhiko Kishibe was an ordinary high school student, until... a tragic car accident leaves him almost dead. Everyone, himself included, gives up hope for him living. Until... a mysterious, evil organization takes his almost-dead body, twisting it and enhancing it, leaving a supersoldier behind. Natsuhiko escapes with his new powers, and dons a mask to hide his identity and protect his family. With his new identity, he becomes... Masked Lion! Defender of truth and hope!

Alright, thanks.

While I thank you for the idea and suggestion, and I am indeed starting writing one of those, I'm writing a more anti-heroic protagonist, so I don't think it will fit if it's a "heroic good guy" contest.

I can explain the latter: When I say "Henshin Hero", I mean things like Kamen Rider or Power Rangers.

Well, I'd like to know if any exist first, so I can play them.

I like those kinds of stories, and I want to see some of them.
