The following is a listing of fictional characters from Lost Girl, the Canadian supernatural drama television series that premiered on Showcase on September 12, 2010, and ran for five seasons.
Main cast
Bo Dennis
Portrayed by: Anna Silk
A Succubus, she has the power to absorb the life force (the "chi", or Qi) of humans and Fae by drawing it out through their mouths. She feeds from chi intake; and heals from the absorption of chi and from the energy created by sexual encounters. She can also seduce and manipulate both humans and Fae with the touch of her skin. Though at first she could not feed without killing her sexual partners (both male and female), with Lauren's help she learned to control her sexual drive and chi-drawing powers so that she can have sex with both Fae and humans without injuring or killing them. She can only go a few days without feeding before the hunger overcomes her. Absorbing the chi of Faes can increase her strength; however, although Fae are stronger than humans and can better endure her feeding on them, she can drain their chi and leave them comatose or dead. She is best friends with Kenzi and is romantically involved with both Lauren and Dyson. When Lauren's life is threatened in "Death Didn't Become Him", a strange and extremely powerful alternate persona emerges from her, which drains the chi from multiple individuals at a distance of several meters, and she declares "there will be no more dark or light, only me." In the first season, Bo finally meets her birth mother, Aife, who is also a succubus. Towards the end of the second season, she learns that Trick is her maternal grandfather and that she is named after her grandmother, Isabeau. In the third season, Bo willingly enters into a monogamous relationship for the first time in her life when she asks Lauren to be with her.
Dyson Portrayed by: Kris Holden-Ried
A Wolf-Shapeshifter and homicide detective in the human police force. He is 1,500 years old, very strong, possesses a sharp sense of smell, and is acutely knowledgeable about Fae politics. A member of the Light Fae, his true allegiance is to Trick rather than to the Ash. He falls in love with Bo while under orders from Trick to keep an eye on her, and is best friends with Hale, his Light Fae detective partner. In the Season 1 finale, he involuntarily sacrifices his love for Bo when he offers his wolf to the Norn in return for her giving Bo the strength to defeat her murderous and maniacal mother, Aife; but the Norn – who demanded his wolf the first time he asked a favor from her in "Brother Fae of the Wolves" – realizes that his wolf is no longer what he values most and takes his love for Bo and his ability to love anyone else again instead; leaving him with the memory of their relationship but unable to feel his passion for her. He makes efforts to remain friends with Bo, which is initially awkward when Bo can't understand why he is distant (until Bo comes to terms with his detachment and declares to Kenzi in "Can't See the Fae-Rest" that her relationship with Dyson is over). After reuniting with his old love, Ciara, their relationship is hampered by Dyson's reluctance to reveal his encounter with the Norn and what he had lost in the exchange; however, he eventually admits to her that he offered his wolf but it had cost him his ability to love anyone. This ability is restored by the Norn after Kenzi threatens to mutilate and cut down her Sacred Tree in "Into the Dark". Although the idea that a wolf mates for life was ascribed to his relationship with Bo, in "End Of A Line" the voodoo witch Laveau told Dyson that his "prison" (i.e. his love for Bo) was of his own making.
Kenzi Portrayed by: Ksenia Solo
Mackenzie "Kenzi" Malikov: a human and Bo's best friend and sidekick, declared as Bo's "property" and "pet" to allow her to participate in Fae society. She suggests Bo use her neutrality and bewitching powers to her advantage to become a private investigator, with her as partner. Kenzi ran away from home at a young age and lived on the streets and underground for a long time before meeting Bo. A small-time criminal, somewhat compulsive pickpocket, and scam artist with a long rap sheet, she can speak Russian fluently and possesses excellent street-smarts. She prefers to be underestimated at first glance and tends to put up a facade of generic sidekick cowardice, silliness, and uselessness for camouflage and to keep herself out of harm's way. Her plentiful extended family, all local diaspora, provide a steady stream of shady connections, sources, and services, usually exchanged over the phone as "favors owed" or "favors called" (as prevalent in real-world Russian culture). This and her character's Russian streetwise slang lines, swagger, and attitudes are all quite authentic in both scripting and delivery, with in fact the only notable faux-Russianism in the series being Kenzi's name. Despite their differences, she and Bo quickly become close friends, with Bo choosing humanity rather than Fae in "It's a Fae, Fae, Fae, Fae World", after Kenzi risks her life to find out where Bo had been taken by Dyson and Hale, and calls out to Bo to help her break out of a spell she had been put under during the trial to determine her alignment with Light or Dark. She has a vast wardrobe of clothing and wigs to change her appearance at will. Kenzi and Hale became friends, and she frequently teases or assists him; and by the third season she has also endeared herself to Vex. Her character is the show's comic relief and primary source of its trademark banter, but being so far from the typical incompetent and bumbling "weakling human sidekick without any abilities", grants it much of its signature style. It can, however, also be noted that her thieving, though not of supernatural origin, is one of the most regularly used special skillsets in the show. Kenzi sacrificed herself to stop Bo's father returning to Earth in the Season Four finale, but although she was resurrected at the beginning of Season Five, she relocated to Spain as she wanted to get away from the fae world and the memories of Hale's death.
Dr. Lauren Lewis Portrayed by: Zoie Palmer
A Human owned by the Ash as his property, she serves as a doctor and scientist for the Light Fae. She was seduced by Bo during their first meeting and hence fell in love with her. She has extensive knowledge of the different types of Fae and their abilities. In the first season, she helped Bo learn how to control her powers so that she could have sex with both Fae and humans without hurting or killing them. It is later revealed that she had a human girlfriend, Nadia, who had fallen into a coma five years earlier after contracting a mysterious virus while in the Congo with her. In exchange for her servitude, The Ash offered Lauren access to the Light Fae's laboratory and resources to find a cure for Nadia's condition. Lauren learned from Lachlan in "Masks" that she was tricked by the previous Ash: he ordered a Dark Fae Shaman to curse Nadia into a coma to insure that Lauren would do everything in her power to find an antidote to the fever that was killing Fae, and then pulled her into the Light clan's fold. After Bo (unbeknownst to Lauren) removed the curse, Lauren and Nadia reunited; but their relationship was soon shattered when it was revealed that Nadia had been infected by the Garuda and he could control her mind and body. Bo was forced to kill Nadia when she threatened Lauren's life leaving Lauren devastated. Grieving, Lauren seeks comfort in Bo and the two grow closer emotionally. In the Season 2 finale, Lauren relinquishes her chance for freedom from the Light Fae to stay with Bo, despite encouragement from Dyson to leave while she can.
In "Caged Fae", Bo asks Lauren to be together in a committed relationship. However, in "Delinquents", Tamsin visits Lauren to furtively carry out one of her mercenary tasks, and intentionally provokes Lauren by telling her that she and Bo kissed without Bo feeding from her (not knowing that the kiss was caused by Trick and Stella touching the Dawning invitation machine at the moment they shared a first kiss in "Fae-ge Against The Machine", which made the machine spark, and propelled Tamsin towards Bo to kiss her). Overwhelmed by all the stress and loss she had experienced, and feeling inadequate in satisfying Bo's succubus nature, Lauren tells Bo that she needs to take a "break" from the relationship. As time passes, however, Bo becomes concerned that it might not be a temporary separation. In "Adventures In Fae-bysitting", a part of Lauren's past is disclosed and we learn that her real name is Karen Beattie and that she is a fugitive wanted by the International Criminal Offences and Criminal Intelligence Bureau. In addition to English she is also fluent in Spanish, French and Swahili. In "Those Who Wander" Lauren feigns being through with Bo in the presence of Dr. Isaac Taft and rejects her to protect Bo, and herself, from him. After this encounter, Bo and Lauren go their separate ways. Lauren then sabotages Taft's plan to extract Dyson's DNA and transfer the cells into him so as to become a Wolf-Shapeshifter, and turns Taft into a human/Cabbit hybrid instead, making him an easy kill for Dyson. She goes missing thereafter. (The conversation that she and Dyson had during a phone call in "Sleeping Beauty School" showed that Dyson was aware of Lauren's motives for subjecting him to the deceptive procedure.) In "Turn to Stone", Lauren reveals to Crystal that she has a brother, they had been inseparable, and decided together "to change the world", but their cause had turned into blowing up pipelines. Lauren knew how to build pipe bombs and made them for her brother to position; however, one location was supposed to have been deserted but wasn't, and eleven people were killed in the explosion. This led Lauren (then known as Karen Beattie) to go on the run, change her identity, and keep running ever since. Lauren confesses that not a day goes by that she doesn't hate herself for what happened. (By the details in the ICOCIB wanted poster, the incident occurred in 1998, when Lauren was 17 or 18 years old.) In "Let the Dark Times Roll", Bo and Lauren are reunited at a Dark Fae party after the passage of a month, during which Lauren's memory of Bo was removed by The Wanderer. They jump into each other's arms and kiss passionately. Lauren told Bo that she had fled for her life after the Una Mens began to kill humans. The Dark Fae (i.e. The Morrigan) came looking for her, offering refuge, protection, and freedom to come and go as she pleased in exchange for working for the clan. When Bo tells Lauren that she can offer her protection by claiming her, Lauren turns her down. After being owned by The Ash for over five years, Lauren doesn't want to be owned by anyone, even Bo. Bo walks away, stunned and bewildered by Lauren's response. In "Dark Horse", Bo and Lauren reconciled after Bo saved Lauren from Massimo. Lauren saw that Bo was wearing the necklace gift from Lauren she had found in "Turn to Stone". When a defiant Lauren tells Bo that she's not afraid of the Fae, Bo admiringly told her, "You really are Dark"; to which Lauren replied, "No, Bo. I'm yours." Bo starts to leave, but turns around and walks back to Lauren and kisses her.
