Premise

The coastal town of Bristol Cove, Washington, known for its legends of once being home to mermaids and mermen for centuries, is turned upside down when a mysterious young woman named Ryn Fisher ( Eline Powell) appears and begins wreaking havoc upon the small fishing town to look for her captured older sister Donna ( Sibongile Mlambo) who was abducted at the hands of the local military. Marine biologists Ben Pownall ( Alex Roe) and Maddie Bishop ( Fola Evans-Akingbola) work together to find out who and what drove this primal hunter of the deep sea to land.

By Season Two, more merpeople started appearing in Bristol Cove due to the pollution in the nearby waters and the sonic waves from the oil rig. Additionally, Pownall's paralysis is gradually being counteracted by Ryn's mermaid stem cells.

In Season Three, Ben, Maddie and Ryn contend with the mermaid Tia (Tiffany Lonsdale) who plans to coerce all merpeople tribes/colonies to join her in her fight to overthrow humanity. And Ryn's daughter, who has been carried by a surrogate, must be protected at all costs. To further escalate matters, Ted Pownall has finally acknowledged the existence of merpeople and seems to be on a dangerous path, just as his paternal great-great-great-great-grandfather Charles had.

Cast and characters

Main

• Alex Roe as Ben Pownall, a marine biologist who helps Ryn when she first comes to shore. He is entranced by her melodious, irresistibly hypnotic siren song, which she deploys on him as a defense mechanism without knowing the full extent of its effects on humans. Ben later becomes Ryn's lover, and his struggle to untangle his affection for her from the obsessive thoughts that result from hearing her siren song becomes a significant part of his character arc. To help Ryn and her kind, he resorts to injecting himself with the stem cells of a partially transformed mermaid corpse and subsequently develops abilities found in merpeople – heightened hearing and reflexes, accelerated healing, and the ability to hold his breath for extended periods of time. At the end of season 3, following the fight against Tia, Ben goes missing in the ocean.
• Eline Powell as Ryn Fisher, a strange young adult mermaid with a dark secret. She comes ashore in search of her elder sister, who has been accidentally captured by fishermen of the North Star fishing vessel. She eventually comes to realize that not all humans are murderous, and becomes Ben and Maddie's lover. To help Ben's mother Elaine, she willingly donates her aquatic stem cells to help counteract the paralysis in Elaine's legs. Upon mating with a bearded merman of another colony when she couldn't find Levi, she has a daughter named Hope.
• Fola Evans-Akingbola as Maddie Bishop, a marine biologist and Ben's girlfriend in season one and two. She works at Bristol Cove Marine Research Center with Ben. Her father is the sheriff of Bristol Cove. Her estranged mother is Susan, who returns after nine months in Season 2. Like Ben, Maddie is entranced by Ryn's melodious, irresistibly hypnotic siren song but doesn't seem to develop the same feelings of possessiveness as a result. She later becomes Ryn's lover.
• Ian Verdun as Xander McClure, a deep-sea fisherman who seeks to discover the truth about the existence of mermaids and mermen. He eventually joins the Bristol Cove Sheriff Department in an attempt to save those he cares about more against the enemy merpeople. In season 3, following the death of Dale, Xander is sworn in as the new Sheriff of Bristol Cove.
• Sibongile Mlambo as Donna (season 1; special guest star season 3), a mystical and deceptively powerful mermaid who is Ryn's older sister. She was unintentionally caught in a fishing net and taken by the military. She was killed, unintentionally, by Xander. Her spirit eventually contacts Helen from the merpeople's version of the spirit world when her body has been grave-robbed. Her ghost later instructs Cami and those on Ryn's side to help Ryn fight Tia.
• Rena Owen as Helen Hawkins, an eccentric woman who seems to know much more about the merfolk than she claims. It is revealed that she is descended from merfolk and shares ancestry with Ben and the other Pownalls. She eventually learns that she has a long-lost relative from the Marzdan family, most of whom are known as hybrids. She discovers that her mother Daphne was one of the merpeople/human hybrids who was promised to fellow hybrid Johnathon Rooney, but had chosen Helen's human father instead. This resulted in the death of Mr. Hawkins, a few weeks before Helen was born. She is eventually contacted by the spirit of her merman love Sarge and, later, Donna's. It is later revealed that she is, in fact, the great-granddaughter of the half mermaid/human daughter of Charles Pownall and his mermaid lover, from her mother's side.
• Tiffany Lonsdale as Tia (season 3), ^[6] a new mermaid from another colony/tribe of the northern seas around Bristol Cove, Washington. The human locals refer to her as a "sea monster". Her intent on arriving on land is to coerce all other merpeople tribes and colonies to join her in putting an end to humans or perish by her wrath. She choose her name from Tiamat, Water Deity of the Seas. In the past, Tia was caught by humans while she was pregnant and she lost her unborn child as a result of how she was treated. As of "Survivor" and "Life and Death," she has since gained leadership of her own colony and is now bent on unifying all fellow merpeople colonies/tribes to eradicate humanity. To symbolize her higher status as the alpha female, she has orange markings on her tail and chest. She learns of Ryn's infant daughter Hope from Hunter, who she threatens with death if she does not join her and her colony. According to Helen, she is a tyrant. During the final battle, Tia is killed by Ryn causing the rest of Tia's followers to stop fighting and acknowledge Ryn as their new leader.

Recurring

• Chad Rook as Chris Mueller, ^[7] a fisherman who was taken to the military base after being injured by Donna. He was held at the facility where he escaped with Donna, only to later fall under their power-mad influence in harvesting the merpeople and their superhuman abilities for their own purposes.
• Curtis Lum as Calvin Lee, an Asian fisherman who is also a friend and roommate of Xander. His girlfriend is Janine, who works at the Anchor cafe. In Season Three, he proposes to her and she accepts. They get married in "Til Death Do Us Part".

• Gil Birmingham as Dale Bishop, the sheriff of the Bristol Cove Sheriff Department and Maddie's stepfather. He is descended from the Haida people. He is the third human to discover the existence of merpeople and becomes another ally. Since the Season 3 premiere "Borders," he has been looking for Nicole at the behest of Xander. During the sound-based terror attack on Bristol Cove and its neighboring towns, Dale is among those affected. Before succumbing to it, Dale helped a crashed car where a mother driving it was affected. This left Maddie devastated and he is succeeded by Xander.

• David Cubitt as Ted Pownall, Ben's father, head of the town's fishery industry and whose great-great-great-grandfather Charles first discovered merpeople in the mid-1800s. He eventually comes to realization that his family was anything but crazy since "Revelations" when he saw Tia trying to kill him but was saved by Ryn. Now distrustful of mermaids and the probable threat they represent, he seems to have set on a dangerous path as his great-great-great-grandfather Charles had.
• Sarah-Jane Redmond as Elaine Pownall, Ben's mother who became paralyzed after a boating accident a decade earlier. She is eventually given renewed treatment from none other than aquatic stem cells from Ryn's mermaid DNA. As a byproduct, she is capable of holding her breathe underwater for about four minutes, though her legs remain somewhat paralyzed.

Debuting in "Being Human" she expressed her sorrow at her husband's sudden demise by "getting tangled in a fishing net" and blamed Ted Pownall for letting his greed for money lead, if unintentionally, to such a tragedy. Many months later, "Entrapment", she received news that her late husband's corpse had been found and now has found peace. In "Mommy and Me" she expresses her doubts to Ted Pownall.

Merpeople

Besides sisters Ryn and Donna, the following mermaid and mermen characters are:

• Sedale Threatt Jr. as Levi, a merman warrior. Mentored by Ben and considers him and Maddie friends. Levi killed Xander's dad Captain Sean McClure per Katrina's command in retribution for humans detaining and torturing Donna. He eventually learns to trust certain humans and considers Ben Pownall a friend of his kind.
• Aylya Marzolf as Katrina, a mermaid alpha leader who was twice defeated by Ryn in combat. She is the most fierce and independent of the colony, displaying brute force against both humans and mermaids if need be. It is later revealed that she was separated from Tia's own colony/tribe as an infant, and raised by Ryn and Donna's colony. She refuses Ryn's offer to return and takes her own life by slitting her throat with Ryn's spear during the fight on an island.
• Hugo Ateo as Frank, better known as Sarge, a merman protector who becomes infatuated with Helen Hawkins and she with him. He dies during the attack on Klesco Oil Company' oil platform. Many months later, Helen finds a way to contact his essence with the help of Eliza.

• Georgia Scarlet Waters as Eliza, a blonde mermaid from Ryn and Donna's colony. She develops a kind of romantic attraction towards Rick Marzdan.

• Katie Keough as Hunter, an olive-skinned mermaid from Ryn and Donna's colony. First appeared on land in "The Last Mermaid" along with Eliza, she confronted Xander McClure. She is known as a natural born hunter and fierce warrior as seen in Season 3 where she trains Ryn for battle against Tia. To avoid death, she divulges the existence of Ryn's daughter Hope to her, whom she later kidnapped. Tia later left her chained up for Ryn to find so that she can deliver a message.
• Aryeh-Or as Ryn's Mate, an unnamed olive-skinned bearded merman whom Ryn had found in place of Levi who she couldn't find. Wanting to conceive a full-blooded merperson to ensure the survival of their colony/tribe and others, Ryn had taught him how to copulate as humans do. With aid from Helen, his sperm was taken and secretly implanted in Meredith's womb, from which his and Ryn's mermaid daughter is delivered albeit with difficulty. He eventually returns to land with Levi to take his infant daughter back, so he can teach her how to hunt.
• Deniz Akdeniz as Robb Wellens (season 3), a new acquaintance of Madelyn "Maddie" Bishop who is ultimately revealed to be a merman from a colony/tribe from Nome, Alaska. Like Tia, he is more human as Maddie had not the slightest inkling of him being otherwise and had lost his ability to change form.
• Sisse Marie and Ben Sullivan as Yura, the leader of the merpeople colony in Nome, Alaska that uses a special pool that enables a female mermaid of this tribe to become a merman for reproductive purposes. Marie portrays Yura's female form and Sullivan portrays Yura's male form.

A few days after her birth, her father and Levi took her into the ocean, so they could teach her how to hunt. After, she was reunited with her mother, she was taught the siren song by Ryn and she was later kidnapped by Hunter in order to bring her to Tia. Hope is rescued by Ben and is reunited with Ryn.

Human/Merpeople Hybrids

When humans and merpeople secretly mated over the centuries, they produce children with a varied blend of bloodlines, from one-eighth, to one-quarter, to half of both species. In addition to Helen, the following characters are:

• Caroline Cave as Beth Marzdan, a long-lost blood relative of Helen and the estranged sister of Rick who leads a community of human/merpeople hybrids.
• Daniel Cudmore as Bryan, a human/merman hybrid, husband of Leena, and father of Meredith, who is associated with Beth and can act hostile towards the Pownalls for their connection to Charles Pownall. When Ryn comes to ask help to have a baby, Bryan arranges for her unborn child to be secretly implanted into his daughter's uterus. After some weeks Meredith suffers from great pain but Bryan refuses to move her to a hospital so, his wife Leena, asks for Ryn's help. When Ryn, along with Cami, arrives at Bryan's house, she stays with Meredith while Cami kills Bryan, when he enters in the house.
• Brendan Fletcher (series 2) as Rick Marzdan, brother of Helen, unknown to her until revealed by a DNA test familial link.

• Kiomi Pyke as Meredith, the secret daughter of Bryan and Dr. Leena who had the embryo of Ryn's unborn child implanted into her uterus in order for her parents to have a full-blooded merperson grandchild of their own. She expressed doubts at what would happen to her carrying a child that is not hers. She eventually manages to deliver Ryn's daughter, but dies as her heart could not take the strain. Ryn then told her niece, Camryn "Cami", to bury her as one of them.

Guest

• Brian Anthony Wilson as Sean McClure, Xander's father and captain of the fishing motorboat The North Star. He was killed by Levi in "Dead in the Water" per orders of the alpha mermaid Katrina. Months later, his corpse accidentally resurfaces.

(November 2020) ( Learn how and when to remove this template message) With more and more people being inflected by Tia's song, it is up to Helen and her fellow hybrids to restore order by turning to Ted Pownall, who is having difficulty accepting his youngest son's transformation. As Tia attempts to convince young Hope to join her in wiping out humanity, Ryn and Ben head off to find her with aid from the military. Maddie asks Robb that he reclaim the same sound waves from the echo chamber of his colony to neutralize the song's agonizing affects. The cure is successful as Xander is the first to recover. He goes to help Maddie in finding her stepfather, but are too late as the song has killed him. Meanwhile, in the depths of the sea, Hope is imprisoned in the crashed airplane as bait to lure Ryn to Tia. On land, the spirit of Donna appears before her daughter Cami and warns her and the others of Ryn's predicament. Cami, Vivian, Levi, Eliza and Ryn's mate ask to use Calvin's motorboat for a sneak attack on the enemy. Ryn is ready to face the rogue mermaid while Ben goes to save Hope with his newfound water-breathing abilities from the stems cells he has been injecting himself with. He succeeds and tells Hope to go to the surface where it is safe. Tia's army has greatly outnumbered Ryn and her remaining colony, but the tide is quickly turned in their favor when Robb's colony arrive with the male Yura in the lead. Ryn ferociously battles Tia and kills her with her spear, thus ending her scourge. All of Ryn's colony, including Robb and Yura, bow down to her in reverence as she is now alpha of all merpeople colonies of the ocean. One week later, the attack is considered to have been from the Russians by the locals. Ted is worried about Ben's sudden absence. Xander becomes the new sheriff of Bristol Cove in place of Dale's tragic death. Maddie decides to travel with Robb to work on the ocean-cleaning project he has started on in order to try and move on from losing her stepfather. She tries to get Ryn to let go of Ben, as all have presumed him dead, but Ryn is certain he will return someday. Atop a rock in the sea, Ryn waits for Ben, who is revealed to be underwater still to parts unknown. However, the shared dream of living together with Hope as a loving family refuses to die.
