Rapeman

Rapeman is a fictional character, who masks up like a true superhero vigilante, and then rapes the heck out of various cunts who deserves it.

Rapeman has a strong sense of justice, and those who gets pounded, all had it cumming.

Arrow

Spoiled billionaire playboy Oliver Queen is missing and presumed dead when his yacht is lost at sea.

He returns five years later a changed man, determined to clean up the city as a hooded vigilante armed with a bow.

Even thou I recommend you to use a firearm instead, his bow and arrows has the silence thou; however it takes years of practice to master the art of shooting arrows from a bow.

To most of us a crossbow will do the trick, with firearms as back-up when the shit really hits the fan.

The series of Arrow raises some serious philosophical issues about vigilantism, it's pros and cons.

Dexter

Dexter Morgan is a forensics at Miami Metro Homicide, seemingly living an ordinary life.

On his sparetime, he goes vigilante upon assholes deserving it, whacking them mercilessly, and dumping their chopped up corpses into the ocean.

This fictional character is by no means portrayed sympatheticly, at least not initially, but he grows as a person as the series goes by.

The Dexter we leave in season 8, the last one, is by no standards the same person as in the first seasons.

It's not enough forensics working around in the world to make someone like Dexter very likely in real life.

Still, one have to admit, a vigilante like Dexter is absolute possible.

A vigilante using tricks from forensics to cover his tracks, is ofcourse very much within the realms of possibilities.

However, a vigilante outside forensics would have a hard time gathering sufficient evidence.

Even thou Dexter is a coldhearted killer, he seldom misses his mark when it comes down to justice.

Dexter never kills an innocent on purpose.

He lives by a code invented by his father.

And he kills by the same code.

Batman

When all godlike, or alien, or somewhat supernatural vigilantes are set aside, Batman is our man of choice.

As a fictional character, set in a fictional city, to call him "realistic" may be over the top, but still, he's actually possible.

His alter ego, Bruce Wayne, is born rich, hence he got the means to gear up accordingly.

Every rich man on earth could actually be Batman, if he so had wanted.

Batman is well trained, has loyal helpers, and use gear that is flamboyant, but not impossible.

It's not a coincidence, me thinks, that Batman is considered the most admired and popular vigilante from the cultural world.
