in marvel comics mighty avengers #2, the first transsexual cyborg is unleashed upon the world. and why would a comic book character become a transwoman, you ask? what else would a “a criminally insane rogue sentient robot dedicated to conquest and the extermination of humanity” become? apparently, marvel’s brian michael bendis felt this would make for a good story. and frank cho renders her accordingly:

via wired’s annalee newitz:

Ultron is a totally awesome android supervillain, and two months ago she became the first male-to-female transsexual cyborg supervillain. Though Ultron has had many forms — my favorite being the giant robot one he had in Runaways — this is the first time Ultron has gone girly. And she’s quite the girl….

I’ve always loved Ultron because he was a giant, flying robot who hated humans and paralyzed his victims with his astonishing encephalo-ray. Now that she’s a chick, I’m just not sure what to expect. Is this just Marvel’s excuse to have a naked chick beat the crap out of the Avengers (not such a bad idea)? Is she actually naked, or is her skin some kind of freaky new armor? Shouldn’t she have a new super power other than nakedness?

based on the reactions of all men who encounter a naked transsexual, i don’t think there is a more powerful super power, for a transwoman anyway.

edited to add:
thinking about it now, i realize it could have been worse. ultron could have been the first cyborg supervillain in a dress.
