That’s an anti-hero

@Bonkidus.Shwonkidus

Thank you. ‏

Vigilante is also acceptable.

@Dr. Nice

Thank you, only my character is similar to (Spider Man) but from another parallel world, and he literally kills criminals, unless they have a family, he will not be killed. I wrote his story briefly in (Spider-Man Wiki). If you are interested in his story, I wrote it about a month ago

Anti-Hero.

There's a ton of examples.

Deadpool

Venom

Morbius

Elektra

Magneto

@RJ Plotner

Thank you, but I mean a custom name. There is a name assigned to a hero who uses the name of justice and is merciless to his enemies.

Frank Castle wants a few words

@Taronerd Punisher fits as an anti-hero.

Punisher is assuredly a vigilante.

Guys, I don't mean a character name, I mean a custom name, meaning, for example, like Luffy from One Piece. Most of Ya's characters call her (Rubber Man) or (Straw Hat). That's what I mean.
