You know, with the costume, secret identity, and so on?
-FrL-
Well, when I lived in Iqaluit, there was a character who called himself “Polar Man”, who went around in a sort of homemade superhero costume. His good deeds were confined to shovelling snow and informing to the RCMP, and his true identity wasn’t much of a secret, but still…
Lots of jokers in badly fitted tights, a couple of vigilante types, but nobody can fight crime the way they do in comics, because in real life they don’t put people into elaborate death traps: they just shoot them.
We’re done this topic many times before, methinks, but I have to leave in a minute so I won’t try to do a search.
May I introduce you to…Angle Grinder Man!
Here are ten.
If I told you then my identity wouldn’t be a secret anymore.
Oh damn
Darn you, Emilio Lizardo, I came in here specifically to mention him!
Nine, really, as I hardly think a cockblocker counts as a superhero. Supervillian, yes, superhero, no. 
I don’t know about anyone else’s screen, but on mine the phrase “people who desperately need professional help” gets lost between the end of link code and the period.
Back in highschool, being the crazy scientist type, I was approached by a guy inquiring if I could possible make a superhero costume and gadgets. I was rather flattered but nothing came out of it, I explained him some things about the practicality of the whole thing.
Quite a pity really, being the geeky gadget maker of a superhero would fit me very well as a career.
