Kolin

"I didn't quite explain myself before. Let me just say that I utterly despise Bison... but there is another man more suitable to lead this world. That's why I want to destroy Shadaloo. Is that satisfactory?"

- Kolin, as 'Helen'

Kolin (コーリン) (pronounced "Colleen") is a non-playable character, an agent of the Illuminati acting as Gill's assistant and secretary. She first appears in the Street Fighter III series and later returns in Street Fighter V, with a much larger role, using the name Helen (ヘレン).

Appearance
Kolin is an attractive woman of apparent European descent with blonde hair and blue eyes. In her first appearance in Street Fighter III, she is distinguished by her asymmetrical updo hairstyle. Kolin wears a finely-tailored black ladies' suit with matching skirt, and walks in high heels.

As "Helen" in Street Fighter V, she wears her hair loose in a more commonplace long style, under a black ushanka hat with a four-pointed star decoration at the center. Instead of her black suit from III, she wears a black military-style jacket with fur accents, ending in a miniskirt. Thigh high black stockings and fur boots replace the stiletto heels of her secretary outfit. While operating as Helen, she speaks English with a Russian accent. Whether this is her true accent is unknown, as Street Fighter V is set before Kolin's appearance in New Generation/2nd Impact and it is unclear if 'Helen' is an entirely false persona or Kolin's original self.

Personality
In Street Fighter III, Kolin appears primarily in the role of dutiful assistant to Gill. When she interacts with other characters, she is a bit standoffish.

As "Helen" in Street Fighter V, she is depicted as a conniving schemer who seems to alternate between two personalities: a false, kind one, with which she acts as a nursemaid to Charlie Nash and a helper to heroes, and her true self-zealous, ruthless, cruel, greedy, selfish, uncaring, and vindictive, seen when she throws Charlie's unavoidable return to the grave in his face.

Helen is deeply religious and praiseworthy, devoted to the teachings of the Secret Society and entirely convinced that Gill is the prophesied messiah. She carries a copy of the Book of Miraha, the Illuminati holy book, and reads aloud from it for strength when she is disheartened. At the end of A Shadow Falls, she is shocked and honored that despite her failure to satisfy the ancient prophecy with her Nash project, Gill still wishes for her to serve at his side.

Street Fighter V
A Shadow Falls A mysterious Russian woman named Helen revives the corpse of Charlie Nash using the eleventh vessel from Urien's laboratory. She and Urien decide to use Charlie to stop Shadaloo's plans, taking advantage of his desire for revenge on Bison. While Charlie is still weak from his resurrection, Helen tasks him with the unpleasant assignment of taking down his best friend, Guile.

After Charlie secures Guile's piece, Helen reveals she has also recruited Rashid and Juri as part of her operation to take down Shadaloo. Urien arrives, and it becomes clear they have an antagonistic relationship, though she refers to him deferentially as "Lord Urien". Urien attacks Charlie to test his mettle, but is prevented from killing him by Rashid. He tells Helen to prove that Shadaloo is truly defeated. Before they infiltrate Shadaloo to stop the Black Moons, Helen uses some sort of power to charge the green gem on Charlie's forehead and keep him alive.

After an unsuccessful attempt at halting the Black Moons, Helen gives Rashid the riddle from his friend whose answer will stop Operation C.H.A.I.N.S. -- and, excited, asks Charlie if he has killed Bison yet. Charlie answers that he has not, and Helen is enraged, complaining that she worked so hard to revive him and rubbing in his face the fact that his new body is decaying rapidly and he is truly dead. Charlie surprises her by revealing he knew this already, and leaves to perform the mission his own way. Helen is last seen comforting herself by reading a prophecy about Gill from the Book of Miraha while watching the destruction of the surrounding city. Urien castigates her for her failure.

In the mid-credits sequence after the story ends, Helen kneels before Gill and tells him of the fall of Shadaloo and Bison's defeat at the hands of Ryu. She apologises for failing him with her Nash project. Gill rises from his throne and asks her to come with him, addressing her as Kolin and apparently using his cryokinetic powers to transform her from Helen into her familiar design from Street Fighter III (it is left unexplained whether the 'Helen' persona was simply a disguise all along or if her existence as Kolin is a new development). Kolin gazes upon Gill's face with worshipful loyalty as the credits resume.

Street Fighter III
Kolin acts as a personal assistant to Gill, managing aspects of the Third World Warrior Tournament.

Most notably, at Gill's behest she gives Dudley his father's car keys back in his New Generation and 2nd Impact endings.

Udon
Kolin appears in UDON's Super Street Fighter comic book series, an adaptation of Street Fighter III.

Most recently she also appears in the 2015 prequel one-shot Street Fighter V: The Life and Death(s) of Charlie Nash, in which she curiously performs the same plot function she does as Helen in Street Fighter V. Here, instead of operating as Helen, she appears to Nash and the reader unambiguously as Kolin, without a disguise.

Kolin and Urien seemingly discover Nash in the desert, approaching him via helicopter, but later reveal they resurrected him in their laboratory to serve the Illuminati. The desert and helicopter are illusions, and Kolin and Urien are actually speaking to a comatose Nash telepathically, using Illuminati technology. Kolin offers Nash a second chance at life if he will serve her willingly, and Nash agrees.

Street Fighter: Resurrection
Kolin appears in the live-action miniseries Street Fighter: Resurrection, credited as 'Illuminati Agent'. She is portrayed by Amy Olivia Bell.

Trivia

 * "Colleen" is a common Irish name also used as a general term for a girl or woman, from the Irish cailín (caile, countrywoman).


 * "Helen", the name Kolin uses while gathering warriors to serve the Illuminati in Street Fighter V, is perhaps a reference to the mythical Helen of Troy, whose face launched a thousand ships to war. It is an English variation of the Ancient Greek name Helenē (Ἑλένη).


 * Kolin's asymmetrical haircut in Street Fighter III, like her master Gill's two-toned skin, was designed to showcase the graphical power of the new CPS-3 board, which allowed non-mirrored sprites for the first time.


 * Kolin shares her birthday with Ken.


 * While Helen wears Russian garb, operates in Russia, and speaks English with a Russian accent, it is unclear whether Kolin actually has any relationship to Russia. Helen may be an entirely fictional persona.


 * Though she has not yet been seen in combat, Kolin is implied to be a fighter by Juri in Act 2 of A Shadow Falls. At the very least, she displays impressive dexterity and sleight of hand in pick-pocketing two chess pieces from Rashid without his notice.


 * In Street Fighter V, Kolin displays a number of supernatural powers: she vanishes into thin air when Nash looks away in Act 1, and she recharges his body in Act 2 by projecting a blue energy into the gemstone in his forehead. She implies she has the power to "touch souls", but cannot do this with Nash as he is dead.


 * In the UDON comics, Kolin uses Illuminati technology to project herself and Urien telepathically into Nash's mind.
