The series as a whole

 * Complete Monster: Certainly Bison would be (as any good wannabe global dictator would aspire to be), but also Seth (since he signs off on the BLECE project, which attempts to use human cells to create a go-anywhere bomb). Vega probably counts too (his hobby as a serial killer probably means he likes being a twisted individual).
 * Getting more specific about Bison: he had to purge himself of all traces of good from within himself in order to harness the full potential of Psycho Power. And he did so very willingly . In addition, there's the fact that he murdered Chun Li's and T. Hawk's fathers, killed Guile's friend Charlie, kidnapped several young girls (the Dolls) from across the world for his own twisted experiments and to turn them into his personal soldiers via Mind Control, and wanted to harness the untapped potential of Satsui no Hado within Ryu for his own plans of global conquest. Not to mention, as Shadaloo's leader he is also responsible for Juri's Start of Darkness.
 * And at least Vega has a Freudian Excuse for his level of crazy (his father, an ugly nobleman, murdered his mother in front of him); Bison doesn't even have an excuse for turning evil beyond Take Over the World.
 * Once you get past the Dark and Troubled Past (specifically, Bison-induced Parental Abandonment) and Evil Is Sexy, Juri Han could be considered one. Considering her winquotes imply she wants to rape and murder her opponents and her general Ax Crazy behaviour...
 * Despite not much being known about him (due to the characters in the SF 3 series not having concretely-outlined back-stories, Urien is implied to be one as well. In Third Strike, he kidnapped one of Chun Li's adopted kids for use in experiments (presumably the same kind that created Necro and Twelve, or something similar), which was only prevented because Chun Li went Mama Bear on him. And while his brother Gill is touted as a Well-Intentioned Extremist despite being the Big Bad, Urien's personality is hinted to be considerably worse.
 * Fan Myopia: Fans have complained about whenever Street Fighter adaptations use Guile as The Hero when M. Bison is the Big Bad instead of Ryu even though Guile is well known as Bison's main archnemesis.
 * Fanon: It's a general consensus in the Fandom that Ken beat Ryu when they met during the events of II. Ken promised not to marry Eliza until he defeated Ryu in a fair fight (during their match in Alpha 2, Ryu was preoccupied with other matters, namely the aftermath of his fight with Akuma) and by the time of IV (one year later), Eliza is expecting a child and actually gives birth to Mel in SSFIV; Mel appears as a child in III.
 * Chun-Li's father is usually referred to as Dorai, which was the name given to him in II V. His Canon Name, if Capcom has even bothered to give him one, has yet to be disclosed. Similarly, she is usually given a surname of Xiang/Zhang (originating from the live-action movie, where all of the characters were given first and last names). It might actually be Chung, but this piece of info reportedly came from a source in the early '90s and was probably forgotten or kicked out of canon by Capcom. Recent games don't bother giving Chun-Li a full name.
 * And from the first live-action movie and American cartoon, several, such as Ryu's last name (Hoshi), Sagat's first name (Victor), Guile's full name and rank (Colonel William F. Guile), and since he was called Dr. Dhalsim in the movie, Dhalsim would be his last name.
 * In the EX series, a common theory claims that EX is meant to be a retelling of Street Fighter Alpha/Street Fighter II.
 * Ibuki is highly subjected to this, particularly in rumors that she's the daughter of Geki from the original Street Fighter.
 * Fans often assume that the Shadow transformation from Marvel Super Heroes vs. Street Fighter happens in the series as well. UDON even used it in the comic.
 * Until Capcom canonized it, Charlie Nash, which is the combination of his American and Japanese names.
 * Fan Preferred Couple: Many fans want R. Mika to at least cross paths with Hakan. Even if their encounter doesn't become romantic, perhaps he can show her the benefits of oil wrestling.
 * Fanon really likes the idea of Ryu/Chun-Li.
 * Memetic Sex God: Or Memetic Sex Goddess, in this case. There are few ladies in this series that don't get this kind of admiration among the fandom.
 * Ruined FOREVER: Basically how the most of the fans react whenever a new numbered iteration comes out that changes the gameplay from the last iteration. The current Berserk Button subject for the "Stop Having Fun!" Guys seems to be Hakan, which is interesting considering how good he is.

The first game
""TIGER! TIGER! TIGER! TIGER UPPERCUT!""
 * Ensemble Darkhorse: Retsu. Despite having appeared only in the original game, he's much more loved by the fanbase than other characters who suffered the same fate, and he has been used prominently in several related media.
 * Narm Charm: The hilariously bad voice acting of the first game. All by one dude.
 * That One Boss: Sagat in the first game.

The American series

 * Big Lipped Alligator Moment:
 * The infamous moment in the first episode when Ryu gets slimed by "Arnold the Pig".
 * In Guile's dream when Escher turns into, of all things, a WEREWOLF. This being the episode "Getting to Guile".
 * The same episode had giant versions of the cast pushing Guile around. That's not even getting into the bacon house monster that Guile and Bison walk inside of in said dream sequence.
 * Every time Blanka flips out in later episodes.
 * Damnd, in the Final Fight episode, sticking electrical equipment into his mouth for what seems to be no apparent reason.
 * Ensemble Darkhorse: Who else but: BISON!!!! *flames rise*
 * Fountain of Memes: "This.is.delicious!", "Bison!", "Naaaooooo!", "Yesh! YESH!", "No! Not the head-bite!"
 * Growing the Beard: The second season has several character arcs through its episodes(i.e. Blanka's accidental further mutation, a growing rivalry between Ken and Ryu, Cammy's brainwashing, and Bison's acquisition of an ancient healing statue that, over the course of the season, drives him to world-destroying insanity). All this and Final Fight, too!
 * Harsher in Hindsight: When Rose looks at her cards, the final one is "Doom", which is portrayed as a flaming tower..
 * Hilarious in Hindsight:
 * "No one has ever defeated Sagat, and no one ever will!" Cut to Street Fighter IV, when Sagat is top tier...
 * Fans cried foul when Akuma merely "injured" Gouken. Then comes Street Fighter IV, which established that Gouken did not die and was simply hiding while recovering all this time.
 * Idiot Plot: In No Way Out, the villains probably would have won if they just used the tanks to bust down the gate first.
 * Memetic Badass: Bison.
 * So Bad It's Good
 * Wangst: Blanka is sometimes criticized as being incredibly whiny about the whole "Mutation" thing. In fairness, he was unwillingly mutated, but literally every single appearance that centered around him had him angsting in some way or another, despite common sense dictating that he get over it.
