Really? I thought since it's in the list of available Pokémon that'd be already proven :/ Ah well.
Anyway, if it's okay I'd like to get her a sig attribute now.
[Faris] Cappun (F)
Ability: Pickup
Sig attribute: Gender Cloak
Piracy is a notoriously male-oriented business. Historically, human pirates were loath to allow women in their crews, a practice that has not been ignored by Pokémon. This discrimination was a big blow to Faris, who since her childhood had dreamed of sailing with a crew of famous Cappun pirates, seeing far-off lands, finding treasure and having amazing adventures. Her disappointment ate away at her until one day, she decided to disguise herself as a male Cappun, run away from home, and join a Cappun crew in hopes she wouldn't be uncovered. As luck would have it, she disguised herself well enough to blend in and was accepted into a crew of the most notorious Cappun on the high seas. For years, she lived her dream, sailing to every corner of the world and seeing places she'd only envisioned in her fantasies. After a while, she left the crew, now a famous pirate with a lifetime's worth of tales and memories of her journies, and was eventually captured by Mike for use in the ASB. Though she no longer practices piracy, she still conceals her gender, fiercely protecting her reputation and secretly fearing that one day her deception would be revealed.
Effects: everyone on the field besides Faris and myself will believe her to be male. Attract, Captivate, and any other moves, attributes etc. requiring a Pokémon to be a certain gender will fail as male opponents will believe Faris to be the wrong gender for them to work, and if a female opponent used one it'd fail regardless. The effects of Rivalry will also be reversed; female opponents with Rivalry will receive an attack boost and males will have their attack reduced. However, this obviously means Faris is unable to use such moves as described above either, as doing so would give the game away. Also, if in any way Faris' true gender should be revealed (for instance, being attracted by something not requiring a Pokémon to know she is female, such as Cute Charm or an arena condition), she will become ashamed and reluctant to attack, meaning there will be a 30% chance she will be too embarrassed to act for three actions from the event that reveals it, and Gender Cloak will cease to function for the rest of the battle.
