(Most of these would take were some PROGRAMMING superpowers, some are about alternate realities, but still :P. Also: excuse my preference for butts. It is an addiction)
For those who enjoy some naked animated booty: the ability to strip ANYTHING off of a humiliated female character (my mind immediately goes to Wonder Woman's star spangled bottoms and the top of Jessica Rabbits dress) in an animated feature just by typing in a command, even if it alters the plot and dialogue spoken.
Those who enjoy videogame booty: The ability to play any game you want, regardless of rating, and pants, shark, etc. whoever the hell you wanted, each NPC with a different reaction, whether you played as the main character or maybe a digital version of yourself
Here's a big one that's very broad and may have been mentioned before: Altering history for the sake of some embarrassing bare lady parts. What if Marilyn Monroe forgot her panties in the famous clip of her skirt blowing up? What if every winner of Miss Universe had her bottoms sn*tched away by (what is now YOUR) altered tradition?
Another big one: Altering laws. By writing in a notebook (no, not death note silly...more like law note
), one could simply make laws on women's clothing. Perhaps they would all be required to remove their top or bottom at the command of any man, no matter how young or old. Maybe the winner of every beauty pageant would have to accept her prize bottomless? What if, depending on if they had big boobs or a big bottom, every test grade under a B would require her to remove her top, bottoms or both? Endless possibilities for innocent women. Bad girls too.
One where every time you turn on the video camera and point it at her...a woman loses at least one article of clothing, instantly capturing you a humiliated babe on tape.
A superpower that causes EVERY attractive woman that angers you or puts you down to at least end up with a bare butt immediately. It's the vengeful/ anti depressant superpower. Also applies to attractive female artists with bad songs, actresses on live TV, etc.
This is a...reversed karma type of power: You slap a woman on the behind, and if she objects at all...(which she likely will), her bottoms basically just fly off of her ass. Same applies to boob grabs and tops.
The ability to replace every picture in a woman's home (maybe even classroom) to a picture of her bottomless, topless, or both (without the hassle of sneaking in, just by thought alone :P)
A power to make every fishing line cast into the water "accidentally" snag onto a lady's top or bottoms, tearing them away.
The ability to write anything about women losing their clothes and have it come true if written as a narrative. (Ex.: She had a perfectly chubby bottom, which was certainly shown off nicely when the shy woman's skirt in front of me was lifted, and her panties soon followed due to a sneaky friend beside her, little did she know her skirt was being blown up as well...her underwear mysteriously ripped off of her hips)
Lastly, the ability to make every woman in the world who is proud of her big bottom...self concious about it
especially after she loses her bottoms from another power.
That's it for now, unless I decide to be an ass and add more soon :P
