There are four character in the SF series who are inspired by various characters from the long-running manga series JoJo's Bizarre Adventure:

1.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.

Here is the original manga panel from JoJo's (read it from left from right) :

2. Rose from the Alpha series was inspired by Lisa Lisa: Rose's outfit is almost identical to Lisa Lisa's and both share a similar fighting style that consists of channeling energy into a scarf, both characters are also known for enjoying baths . In addition, Rose's stage in Street Fighter Alpha 2 is Venice, which is the same city where Joseph Joestar meets Lisa Lisa in the story.

In this video by Capcom UK, they admit that Rose is inspired by Lisa Lisa: https://www.youtube.com/watch?v=epRNJVK5yNw#t=1m15s

EDIT:
Rose's Soul Drain move is inspired by a scene in Jojo where Lisa Lisa puts a breathing mask on Joseph Joestar.

Here's a comparison pic, taken from JoJo wiki:

The full scene of Lisa Lisa putting the breathing mask on Joseph can be seen on the previously mentioned "Lisa Lisa's introduction" (start watching at 1:56).


3. Juri Han from Street Fighter IV was inspired by Jolyne Kujo/Cujoh, aspects of Juri's design, such as her hair and chestwear, are resmincent of Jolyne. Along with this, Juri has a spider motif and cleaves a butterfly in her official artwork, while Jolyne has a butterfly motif and spiderweb-patterned clothes, her Stand also turns her body into threads and webs. Both characters also use the same "ora ora ora" battle cry.

4. The fourth one is Guile, thought I don't think it needs to be here. That one has a different source other than this thread. But in short, he was inspired by both Polnareff and Stroheim, with his name coming from J. Geil.

I never thought I would make another entry on this thread almost six years after it was made. Now that I look back, I realize that this is one my most successful threads in terms of viewcount.

Here it is, the FIFTH character.

In Ultra Street Fighter IV, Decapre has a taunt that is identical to Muhammad Avdol's "Yes! I am!" pose. Character Action 10.

EDIT: Why didn't I post this one sooner? I'm sure I already knew about this one years ago. Eh, maybe I just forgot about this trivia.
