If you don't remember Poison from the home console versions of Final Fight, you're not alone. Don't worry about it if her name doesn't ring a bell: she and her twin sister, Roxy, were edited out of the SNES and GBA versions in order to make the game a little more family-friendly. She has, however, appeared as both playable and background characters in other Capcom games since her first appearance in Final Fight, with her 1980s hooker-wear largely unchanged over time.
However, Poison has become noticeably more feminine as time's gone on, even though she is one of the few official transsexual characters in gaming history:
According to David Sheffs' book Game Over, Nintendo stated that Capcom could not have a female enemy as that violated Nintendo's ban on violence against women. Capcom countered that there were no female enemies in the game, revealing that the female characters Roxy and Poison were also in fact transsexuals. The characters were nevertheless removed from the SNES version. However, in 1993, Sega obtained the rights to release the game for their Sega CD. In a sign of Sega's more liberal polices, the female enemies could remain in the game, but with less-provocative clothing; also there could be no indication of their supposed transgendered status (Sega of America would later remove a homosexual boss from the Western version of Streets of Rage 3).
Now, you can embrace your inner tramp by snagging this eleven inch-tall beauty from Hobbystock and placing it on your dresser. Just think about it: you could throw on your Dungaree underwear and be twins! Excuse me for a second, but I need to go rinse out my brain for conjuring up that particular image.
