Helena

Helena is a clone of Anglo-Ukrainian origin on Orphan Black. Her "tag number" is 322D02.

Like her twin sister, Sarah, she was taken from the system and thus was unmonitored, unlike the others. She serves as one of the antagonists in the first season, and from the second season onward, a main protagonist.

Helena is at once psychotic and childlike. Despite being a proven killer, capable of firing a sniper rifle and wielding a unique fish pommeled dagger as her close range weapon of choice, she enjoys sugary products and exhibits childlike mannerisms at times. She appears to have spent much of her time in the ramshackle abode with Tomas and Maggie, who possibly trained her cold-heartedly and have been psychologically manipulating her. Helena self-mutilates, and has multiple scars on her back that somewhat resemble wings.

Helena's abusive experience growing up in a Ukrainian convent left a lasting impact on her. She developed a playful and caring nature towards children, and hoped to have children of her own. While at the Johanssen ranch, she let a little girl play with her hair. This prompted Alexis to spank the girl for not listening. Witnessing this, Helena grabbed Alexis by the throat and threatened her, having been reminded of her own childhood in the convent.
