Teresa Nielsen-Hayden is on the case of Angle-Grinder Man (superhero with a website), Superbarrio, Terrifica, Mister Twister, and Polarman, Masked Hero of Iqaluit.
"Any parent who gets a phone call from his son saying, `Oh, you might see me in the newspaper; I'm a superhero wheel clamp vigilante' - it might take them a little while to formulate their views," [Angle-Grinder Man] said in an interview. [+]
For the record, "I'm a heterosexual superhero," Angle-Grinder Man said, "although I have no problem being a gay icon." [+]
Teresa's conclusion:
I believe we have enough data to say that real superheroes tend to work in support of single issues, or on behalf of the needs of specific populations. I don't expect the writers at DC and Marvel to take notice of this anytime soon. [+]
