Lead designer of Street Fighter II, Akira Nishitani, stated in a interview with Polygon that the concept of Dhalsim's ability to stretch his limbs comes from the Ripple "Zoom Punch" technique.[40] This is reconfirmed in the comment section of Dhalism's bio in the Street Fighter X Tekken Artworks artbook.
In an interview with producer Noritaka Funamizu, he reveals that Guile's overall appearance was modeled after Jean Pierre Polnareff.[41] Guile's page in Street Fighter X Tekken Artworks goes into detail, explaining that early designs included Polnareff's vertical, yet modest hairstyle, but at the time the sprites were being made for Street Fighter II, the pixel artist jokingly stretched Guile's hair out to the sides. The team found it amusing and decided to give him "the always distinctive Stroheim look" instead. Noritaka also explains that Guile's name was derived from Polnareff's archenemy, J. Geil, though this was apparently the result of a mix up from the development staff at the time.
During early stages of development of Street Fighter II, Guile's "Sonic Boom" attack was originally referred to as "Divine Sandstorm", in reference to the character Wamuu.[42]
Rose was inspired by Lisa Lisa, her outfit is almost identical to Lisa Lisa's and both share a similar fighting style that consists of channeling energy into their scarves (Soul Power in the case of Rose and Ripple in the case of Lisa Lisa). Additionally, both characters like to take baths and Rose's stage in Street Fighter Alpha 2 is Venice, which is the same city where Joseph meets Lisa Lisa in the story. Furthermore, in Capcom Fighting Evolution, the Midnight Bliss attack would turn her into either a masked gondolier or Enya the Hag with a tweaked sprite from JoJo's Bizarre Adventure: Heritage for the Future
Juri Han has hair and clothes similar to Jolyne's. In addition, Juri has a spider motif and cleaves a butterfly in her official artwork; Jolyne has a butterfly motif and her Stand turns her body into threads and webs + she has spiderweb-patterned clothes. Juri even has the same "ora ora ora" battle cry as Jolyne.
In Street Fighter V, the DLC character Seth has many moves based on older Capcom fighting games including JoJo's Bizarre Adventure: Heritage for the Future. His Hecatoncheires move is based on Jotaro and DIO's Blazing Fists, with the EX version of the attack ending with Jotaro's Star Breaker as Seth yells "ora ora ora". Some successful combos can lead to Seth doing DIO's Time Stop pose.
