Obviously, there are lots of things to consider here. First, you want to cater to your player. After you hear more detail, you'll have a better feel for what she expects for her character. At the same time, it's a group game and you don't want to deprive the other characters of their fun or give the impression of overt favoritism of one player. Obviously, you need to know their comfort zones as well. Keep in mind that gender only plays a part in some issues: rape is a tragic happening that effects well beyond the victim. Male gamers might have a mother, sister, aunt, girlfriend or wife who has been a victim (or they themselves may have been sexually assaulted) and would be very uncomfortable or worse at such a topic.
Personally, I would never make such an occurrence a part of my games narrative unless I knew all the players were OK with it...and even then it would not be an active element 'on-camera', so to speak. It also depends on the nature of your game: a four-color punch fest shouldn't be highlighting dark personal tragedies and social issues. If your players are used to 1968 Avengers, don't suddenly drop them into 1986 West Coast Avengers.
So let's attack this from an entirely different angle. We can offer up a super-villain plot without going directly political, per se. Obvioulsy the player wants to reinforce her character concept...but she doesn't want to actually be doing social work, she wants to help women's rights using heat-vision, near invulnerability and telepathy. So let's find ways to make that happen.
How about these for a start?
DATELINE: EMPIRE CITY! City center was terrorized this afternoon by the sudden and shocking appearance of a group identifying themselves as The Savage Front. Claiming to be dedicated to returning society to the Old World Order, these madman destroyed a CIMCO gas station, sabotaged the Deacon Street Power Station and forcibly dressed several citizens, forcing the men into more formal suits and covering the women in blankets to "cover their exposed limbs and remove their sinful shapes". This bizarre cult uses some sort of magic serum to temporarily change themselves in 'Retro-Men'. They have sworn to strike next at the Modern Museum of Art, this station's broadcast center and at Billingsley College, which has just opened it's 'Sojourner Truth' exhibit in their school library.
Our idea here is to present villains who list women's rights as but one of their many offenses. I kind of envision them as villains who change into all sorts of silly or themed villains, like a Cro-Magnon, a Knight, a Gentleman, a barbarian and so forth. They aren't inherently EVIL, so much as massively misguided, perhaps. Some of them may be more sympathetic while others are reprehensible in the extreme. This presents a chance to reform some of them, while still having the problem solved with punches.
NEWSFLASH: EMPIRE CITY! Citizens were stunned today by the sudden and violent appearance of a being claiming to be Dionysus. This cell-phone video shows the at-first harmless looking man walking naked through Clements Park, demanding something in what we believe to be some version of Greek or Latin. As his patience clearly runs out with the taunts of passers-by and onlookers, this man somehow incites several of the women in his immediate presence into berserk rages, attacking everyone in the crowd but him and this pregnant women and some nearby children. We're going to have to cut the video here, I'm afraid. At least two of the women bite and then...I'm sorry, according to our reports they actually ATE some of their victims flesh before they ceased attacking. The women are now all in custody and have identified the man, who disappeared shortly after, as the Greek God Dionysus or the Roman God Bacchus. They claim they are know Maenads and they will help him find his mother. It is unclear if they are being controlled and if so, how they can be restored to normal. Authorities are warning any citizens who encounter this man to avoid him at all costs and to not anger or interfere with him in any way, but to contact authorities IMMEDIATELY. This has been a FMN special report.
The approach here is meant to combine several different ideas that can be used in several ways. Dionysus/Bacchus, like most of the Greco-Roman Pantheon, has a pretty tortured family life. Whether this villain is the actual deity or just a crazy guy who's developed superpowers (who may believe he's the real McCoy), you can use his story to push a superhero story. Dionysus' mother was killed before he was born by gazing directly upon Zeus. Why? Because she was impregnated by a mortal man and then so shamed and unable to admit the truth publicly, so she lied and said that Zeus did it. Zeus was totally not cool with that and appeared in all his glory and accidentally killed her. Realizing that was a dick move, he removed the unborn Dionysus from her body and planted him inside his leg. Don't look at me like that, it's the legend.
Annnyhow...its implied, I think, that King Penthius was responsible.
Dionysus eventually rescues his mom from the afterlife. Other versions of his tale have him as the son of Jupiter, but we're using the play The Bacchae as our inspiration, here. Dionysus has the ability to make people freak out and lose their inhibitions....but he also has the ability to possess his followers and a special subset of his followers become the Meanad, rabid female warrior worshippers who go nuts and kill animals and sometimes people and eat them in tribute. So you've got insta-villains right there, with Dionysus as their leader. Further, you've got lots of angles to play this: his mom, Semele, might be here and he's trying to find her. Or he's trying to enact revenge on someone he thinks is responsible...maybe rich industrialist Alexandros Zeus, shipping magnate. Perhaps he's trying to recreate the Bachhanilia, mad that people have forgotten how to truly PAR-TAY. Even if it's against their will.
I'm sure there are plenty of other avenues that would probably satisfy the dual goals of satisfying this player's desire to feel like she can positively impact the lives of women and all of the players desires to PUNCH THE LIVING HELL OUT OF A DUDE.
