As a female Zero have an ability to sell own panties.
Girl's orgasms counter in UI.
Regarding Gwen's power.
She's a 4th wall breaking merc, able to 'rewind' reality.
Resetting stats, time, sperm (exists in form of Jube's ability already) or action points doesn't make sense, since she'll just rewind time to that point, removing all progress, and no one except player and her would know that happened. What could probably make sense is the ability to restart the game keeping unlocked abilities, levels and perhaps income; Gwen would also retain her stats and abilities. Alas, it's likely hard to implement, but it would be nice to not start from scratch every new update, unless you use console of course.
Teleporting (as traveling between pages) or traveling not consuming time is rather unnecessary, since traveling is a very small part of the game, and you know where to find a girl thanks to Kitty's ability, or you can just call a girl to come over. Oh, and it's Gwen's innate ability, so why and how would Zero be able to copy it?
Her power boils down to having knowledge about other characters and their secrets. What fits in this category:
- knowing which complements will succeed;
- correct massage sequence (freely availible right now, which doesn't make sense - how Zero knows it right after meeting a girl for the first time);
- when and where Xavier stashed money (also a freeby, but worth considering for raids with Kitty/Storm);
- when girl takes a shower (rather minor, unimplementable if girls are randomized upon entering showers);
- reduction of stat losses from actions.
Granting bonus xp in Danger room is a solid option through and through, as she's a mercenary.
She could also go on missions, gaining xp and bringing back money. But why would she share money though? Unless you 'convince' one or few of the girls to join as support. Basically, yeah, missions, with guaranteed money and xp rewards, lasting for a few days.
In theory, it could be turned into solid minigame with various types of missions (covert or field combat, thievery/rescue or assasination), different challenges (tech, terrain, enemy types), and girls could have different roles, like Kitty - hacker, infiltrator; Laura - brawler, etc. Although, bringing Storm and Jean would render most obstacles obsolete. Oni once promised some combat system, but... oh well. Missions could become a substitute or foundation for combat.
But realistically - well, it's a porn game.
Overall, given her comics power, it is difficult to imagine any fitting fun and meaningful ability for this game. So perhaps it's best to think about ability based on her character (as in who she is in the game or Marvel universe) or her personality. For example, in comics she recieved her costume similar to Deadpool's because tailor misread the order and thought she went under alias "Gwenpool". What if we use another side of her comics origin - Spider-Gwen - and make player's jizz extra sticky, so girls couldn't remove it, only wait until it dissipates the next day. Oh, and make Gwen complain about such misrepresentation for a good measure. Like 'Me being a r63 Deadpool isn't enough, now Prime confused me with Spider-Gwen'.
