Most of people said that Gunpowder was guy, but be honest, Gunpowder was: "Female, but identifies as a guy. If anyone but Bluegill were to mention it, he'd have no idea what they were talking about."- Latiass( you know he is one of PurpleKecleon's friend), at Latiass's profile. Someone would found out Gunpowder is female if someone look at Gunpowder's fin was...NO CHIP ON "HIS" FIN! Anyone saw that? If anyone can't remember, GO TO THAT [link](Pokémon)#Gender_differences
No notch in dorsal fin shows GP is a dude, unless there's some way to 'heal' or hide said notch...Yet Bluegill repeatedly calls GP lass and GP never denies it, claiming it's 'over with'...this will be an interesting backstory indeed.
