Vivian "Viv" Fisher is a recurring character on Freeform's series, Siren. She is portrayed by Alvina August.


Being a part of Ryn and the late Donna's colony, Viv is willing to comply with Ryn's orders. She does have a bit of rudeness as she hisses at Cami to force her to make room for her to sit, only to be reprimanded by Helen. She also displays a high level of curiosity as she is mesmerized by the candle flame lit by Maddie who teaches hem about fire. She is the weapons master in her mermaid colony.

Physical Appearance

Viv has dark skin like Cami and long, frizzy, black hair that flows down her shoulders. She has light blue eyes. She also appears to be either the same height or a little shorter than her friend Eliza.

Throughout the Series

Season 2

Viv and the other merfolk arrive on land when Klesco Oil uses sound waves to map the ocean floor. She acquires clothes from Helen and meets up with Ryn who she thought was dead. Viv and the others are then moved to the log cabin where Ted and Elaine Pownall have not visited in ten years.

In the episode "Oil and Water" she receives her own ID courtesy of Jerry, she and Eliza live in Helen's apartment for a while. In "Distress Call", she unhesitatingly joins Katrina's group in order to return to the ocean. After "Primal Instincts", she and the rest of her mermaid colony work together with Ben, Ryn, and Maddie to take out the drill from Kelsco's drillship. After seeing Sarge's neck get slit by the sharp hook, she carries his corpse with her colony and swims back to their home, she is present at Sarge's burial.

Season 3

She returns again in "Mommy and Me" when she, Eliza, Cami, and Katrina learn of how large Tia's tribe. In a plane wreck they are surrounded by Tia and her subordinates, she witnesses Katrina's betrayal as she sides with Tia, she sadly did not survive. Ryn and Cami bury her body soon after.



Eliza seems to be Viv's closest friend in their colony. They are almost never seen without each other and even go so far as to live together at Helen's.


She has had great respect for her former leader, but is eventually forced to follow her as she threatens her with a knife to return home with her to sea, where there are no humans and no Ryn to plague them further.


She is a good friend and possibly a surrogate mother to the daughter of the late Donna and looks out her, as she no longer has her mother by her side.


She now comes to respect and obey her new leader without question as opposed to Katrina.


Upon realizing that she is one-eighth mermaid, she accepts her aid and presence in the cabin.
