You know, like Superman or Batman or Wonderwoman or Spawn or the X-Men or the Watchmen or the Justice League...

I'm looking for a manga that has superheroes like that, with similar plots (must remain masked/disguised, must battle against powerful super-villains, must fight crime as vigilantes, etc). The superhero can be male or female, can be alone or with a sidekick/team... That doesn't matter as long as they have the other "typical" superhero characteristics as mentioned above. Superpowers are not a must, because if you recall, Batman was a superhero without any other powers... BUT the superheroes MUST have secret identities! That is why they will be wearing masks or capes or something similar to hide their identities...

Any genre except hentai or extreme ecchi okay. (Mild ecchi is all right, as long as the fanservice is minimal.)

Thanks in advance!

The only superheroes in manga that i can remember are:

zetman kind of like batman meets tha guyver
Ultimate!! Hentai Kamen no its not porn.
Theres one with a guy in a motorcicle and a cape... he uses a white costume and a cresent moon in the mask but i dont remember tha name and ITS OLD.

This is tough for me!! I like to find manga on vigilante costumed heroes, but that's just...not easy.

Sailor Moon and Sailor V are the obvious ones about people trying to keep their secret identities from the general public. Except, some of them fight against demons and aliens.

Tiji-kun! is not quite about a masked guy, but he does fight to protect people, relates to super-heroes in heart, and tries to hide his identity from people in school.

Matsuri Special is about a girl, who tries to hide her wrestling identity from everyone. Wants to be normal but can't. She sometimes use her wrestling identity to help people.

D.N.Angel- main character tries to hide the other soul, who shares his body, from the outside world. Sure, he comes from a family of thieves but it's for good reasons against evil.

Anime-wise, I could recommend the second season of Onegai My Melody, because that has Usamimi Kamen (Bunny Mask Man), but I don't know if you like cute stuff from Sanrio...

You gotta get that Ultimate!! Hentai Kamen, which really isn't porn and is hilarious.

What about Japanese superheroes? Henshin Heroes go about it their costumes fighting criminals(usually generic evil organizations but...) I mean Kamen Rider Spirits and the such are good... Though that's the only non ecchi manga example that I can think of off the top of my head.

Maybe...Wolverine: Snikt?

OOOOH, WOLVERIIIIINE. <3

Thanks to everyone for these awesome recs! I'm pleasantly surprised by how many manga there are that match this request! Please keep recommending.
