Katrina is a recurring character on Freeform's series, Siren, debuting in the first season.. She is portrayed by Aylya Marzolf.

Katrina is a very fierce and strong mermaid, who was once leader/Alpha female of her colony for many years, which meant that all of the colony had to follow her commands without question.

Official Description Edit

An alpha leader of the mermaid colony.[1]

Early Life Edit

For many years, she was alpha female of the entire colony and ruled with a fierce, predatory heart.

Physical Appearance Edit

Katrina has lighter tan skin with freckles across her face, deep violet eyes and shoulder-length light-brown hair.

Like all mermaids, her mouth has sharp fangs and a gray fish tail.

Personality Edit

As a mermaid, Katrina is naturally violent and aggressive. However, she also follows a strict code and feels morally obligated to uphold them when pertaining to her mermaid colony. Katrina was willing to kill Ryn out of fear, derived from Ryn staying on land for a long period of time, which broke her strict moral code. Katrina’s murderous nature, however, got the best of her and caused her to lose her leadership position in her mermaid colony to Ryn, who bested her in combat, but spared her life, once she surrendered to her.

However, she seems to hold resentment for being stripped of her leadership and harbors a desire to return to being the "alpha female" of their colony by battling Ryn again in a tank, with Helen, Maddie and a reluctant Ben as witnesses. Katrina is quite stubborn, but eventually learns that she must trust Ryn and her human allies in order to get what her fellow-mermaids/mermen all want: their oceanic home back. Despite Katrina’s initially-calculating and intolerant behavior, she eventually learned to work with those around her whether she liked/trusted them or not.

Throughout the Series Edit

Season 1 Edit

Katrina rises to the surface with Donna and the warrior merman Levi. The three of them take human form and proceed further onto land.[2]

After putting on the clothes she had stolen, she appears in Helen's shop, where she is intrigued by Helen's keepsakes of the things from the sea. Once she finds Ryn, she and merman Levi attempt to take her by force or kill if necessary to get Ryn to return home. She and Levi reveal their true purpose via hissing; that they are here to eradicate humans for what they had done to Donna while experimenting on her, and kill Ryn because of her attachment to the humans.

She escapes and is pursued by Dale Bishop, but manages to elude capture. Then, after she confronts Ryn, Ben, Xander, and Donna, she, along with Levi, fights against them before retreating. She then acquires some antique spears from Helen's and uses them as weapons for her fight. She then escapes into the cargo hold where she ambushes Ryn. However, her aggressiveness took hold of her, and she gets bested by Ryn and surrenders after a beating. After Donna gets shot by Xander, she helps transport her to Helen's home before Ryn tells her to return to the colony and never return, under orders that she tell the colony that Ryn is dead.

Season 2 Edit

Many months later, she eventually chose to return to the land where the humans dwell, along with Levi and four others: three fellow mermaids and one merman. Accepting Ryn's help, now she is the alpha female, she and her fellow merfolk take Ben's request to dwell in the cottage of his family which his parents have not been in for a whole decade.

Still resentful of losing her role as leader to Ryn, she is more hostile than the other four who came with her. Especially towards Ryn, considering her "weak" like humans. After running off, she encounters the same gray wolf that had attacked Cami earlier, and ended up killing him in a bloody battle. She returns to the abandoned Pownall cottage, carrying the wolf's corpse on her shoulders.

Afterwards, when Ben and Maddie create a tank that serves as an emergency for the merfolk for dehydration, she discovers that Ryn is already weak from the dehydration.

She was somewhat seriously injured in the fight with Ryn and found by Xander, who had then captured her. Imprisoning her in a hatch on his late father's motorboat, he interrogates her about Levi's whereabouts. She tries to escape but Xander shows her the boat of the oil rig that is preventing her and the rest of her people from returning home. He claims that he will help her if she helps him with his "problem."

She eventually succeeds in escaping and intends to have Levi and the other three return to the sea, where there are "no humans and no Ryn", by force if necessary. After seeing Ben's genuine assurance that he would do all in his power to save her and her kind, does she warm up to some. She then takes part in foiling Klesco Oil's plans for drilling in their home, but the plan costs them a member, Sarge. She along with the others swim with him back to their home where he is given a burial. After some time, she brings Cami on a hunting trip and explores a plane wreck. When she pries open a door, she finds, to her surprise, a sickly elderly mermaid inside.
