Kolin (コーリン Kōrin?, Russian: Колин), also known by the alias Helen (ヘレン Heren?, Russian: Хелен, Khelen), is a video game character from the Street Fighter series, first appearing in Street Fighter III: New Generation as a non-playable character before making her playable debut in the second season of Street Fighter V. She initially takes on a benevolent persona and acted as if she cared for other people, when in reality she is a conniving and devoted agent of the Secret Society, primarily serving as Gill's personal assistant. Kolin has long 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. This outfit returns as her 'Nostalgia' labeled costume in Street Fighter V. In Gill's character story, she was seen wearing dark pink eyeglasses. 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. 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 supportive figure to Charlie Nash and a helper to her other allies, such as Rashid, and her true self: zealous, ruthless, cruel, and vindictive, seen when she snaps and throws Nash's unavoidable return to the grave in his face upon Nash expressing doubt in his ability to take down Bison. Despite loathing her adversaries, she was open to admitting that Bison was a thorn in her organization's side as much as he was a problem to Nash and Ryu, however she used Nash for her own personal gain regardless. If Kolin is involved in a fight, she lets her true personality show by belittling her opponents and usually identifying them as inferior to her.
