Leader of the Boston Vampires (2012)
Suren is around 700/800 years old, and her biological father was a Mongol warrior who taught her how to skin animals and humans alike. During the 1930s, Suren was previously being watched over by Aidan and his protégé Henry, forming a relationship with the latter when the former restrained himself from her affections. However, Henry could not keep himself satiated with Suren as a lover, leading to her finding him with another woman at a ball at the Halloway Hotel the night before she and Mother are to leave Boston. Killing the woman in front of a room of human onlookers, all of whom where slaughtered under Mother's order to ensure their kind's existence is not exposed, Suren is punished for jeopardizing all vampires by being placed underground for eighty years.
After Bishop's death, Mother decides to release Suren (feeling that she had served her penance after 80 years) early to take over the Boston vampire instead of Aidan and is stationed in
the hotel where she ironically caused the bloody massacre. Her assigned task has been to rid the city of all the orphan vampires and vampires not loyal to Bishop.
With Aidan as her second in command, Suren first picks a new police liaison in Cecilia and personally sires her when Aidan refuses to. Regardless of her dissatisfaction with Aidan, she throws the Dutch out the trail when Heggeman ends up missing as a result of his death at newly transformed Nora's claws. When Suren decides to bring in a mobster into the vampire fold, Aidan protests, even though the mobster has caught one of Bishop's orphans who attacked children in broad daylight. When Aidan acquiesces later, he begins feasting on the mobster when he should be turning him. Suren is pleased at this turn of events, knowing it is what Aidan needs to become the vampire she knew ages ago and become her lover. However, Mother is less than thrilled that they have been enjoying each other rather than working and orders Suren and Aidan to hunt down Bishop's orphans. Months later, Suren has told Mother that they have culled all of the orphans, leading Aidan to use his renewed relationship with Henry to gather up the orphans. Suren, who has been watching, orders that the owner of a house who gets paid for vampires to pass the threshold to transfer ownership to her human liaison. She then orders the orphans to be uninvited, killing everyone but Henry and Aidan. Aidan later presents Henry to her, and she decides that in order to be properly punished for his actions 80 years ago, she will skin Henry alive, a painful procedure that as a vampire he will survive from.
Later, Aidan convinces Suren to experience the "mundane" aspects of his life, which begins by having dinner with Josh, Julia, and Sally. After impressing Josh with her love of Antiques Roadshow, she realizes that Aidan previously was in a relationship with Julia, but puts off everyone's fears by making the situation better. That night, she expresses her fears that she does not fit in with Aidan's world, but he assuages the fears. The next day, Mother returns to Boston to express her gratitude that Suren was able to shape the city back up. She rewards her by placing her in charge of New England, while excommunicating Aidan from the vampire clans. To escape the oppression, Aidan and Suren run away together to a hotel to start, but Suren soon grows hungry. After Aidan is attacked by other vampires, she asks him to give up, and she will return to Boston. Aidan promises her that he will find a way, and he leaves Suren alone in the hotel, where she goes through withdrawal and thinks about the past. She decides to return to Boston to take her place as its leader, eventually telling Aidan that she did it to save him from Mother's oppression. At Mother's going away party, Mother names Suren as her successor, but gives her one last task to show she is truly strong: Suren must kill Aidan. Suren refuses, as she loves him, and falls to the carpet. As Mother cuddles her, she stakes Suren, and she crumbles to dust in front of Aidan and the vampire council.
- Publicity materials for season 2 indicated that the character was to be named Izumi, but this was apparently changed during production.
