She was also added as a playable character to Ultra Street Fighter IV. Following those aborted attempts, she ended up appearing as a playable character on Street Fighter X Tekken. She was also to appear in both Capcom Fighting All-Stars and Final Fight: Streetwise however, the former was canceled and she was omitted from the latter as development progressed. Poison first appeared as a playable character in Final Fight Revenge. After the Final Fight series, she later appeared alongside wrestler Hugo, acting as his manager, with her schemes revolving around finding a tag team partner for him or developing their own wrestling organization. However, that was not considered satisfactory and both Poison and her palette swap Roxy were replaced by the male characters 'Billy' and 'Sid' and have been for every subsequent North American port of the title on Nintendo consoles and handhelds. Originally conceived as a female thug in Final Fight and part of the game's antagonist group, Mad Gear, concerns during the game's development about reactions from North American audiences to fighting women led to the character being re-imagined as a ' newhalf'. She is voiced by Atsuko Tanaka since the Street Fighter III series and Masae Yumi in SNK vs. Created by Akira Yasuda for Capcom, Poison first appeared in the original Final Fight alongside a similar character, Roxy, later appearing in Capcom-produced games, media and merchandise related to the Street Fighter franchise.
