 * For the president of the United States, see Olivia Marsdin.
 * For the resident of of Earth Sixteen, see Olivia (Earth Sixteen).

Olivia is a resident of National City and former member of the Cult of Rao. She later became disillusioned with Rao and Supergirl, joining the Worldkillers along with the cult's leader, Thomas Coville. Under the Worldkillers' agenda, she led the Cult of Yuda Kal, which worshipped "the Beast" of the Kryptonian religion and briefly turned into a Worldkiller-like vessel for Yuda Kal.

Involvement with the Cult of Rao
During spring break from school, Olivia found out that her boyfriend and best friend, the people who she thought most trustworthy, were hooking up behind her back. Depressed, she snuck into a rooftop party that night to drink her sorrows away. Whilst drunk, Olivia fell off the ledge and began plummeting down to Earth. She was initially resigned to her fate and hoped it would be quick. However, Supergirl saved Olivia and comforted her, telling her everything was going to be okay.

After being rescued, Olivia got involved in Thomas Coville's Cult of Rao and became a devoted follower of his, with the two of them bonding through their faith. In late 2017 when Kara Danvers, James Olsen and Winn Schott arrived at a cult meeting, Olivia welcomed them and recounted how her first meeting was "transformative." During the meeting, Olivia told her story of how Supergirl saved her, which helped her find her way in life.

Soon after, the cult began to take their faith to the extreme. Olivia even encouraged her new boyfriend to risk his life by setting a building on fire and see if Supergirl saved him. She later attended Coville's gathering under a hockey stadium with the BetaHedron as he promised that Supergirl would save them even now, along with everyone else. However, when Supergirl arrived and tried to disable the BetaHedron, she was weakened by Kryptonite soil inside and cut her palm, proving she wasn't a god. Olivia then questioned whether what Thomas told them of Supergirl was true and ran away in terror with other cult members before the BetaHedron could explode.

Leading the Cult of Yuda Kal
Olivia became disillusioned with Supergirl and grew lost. She began visiting Coville in prison, where he claimed that they were worshiping the wrong God and that Reign was their deliverance, telling Olivia of the Worldkillers' prophecy of darkness. After Coville's escape from prison, Olivia joined his new cult, which was devoted to the Worldkillers and Yuda Kal, the goddess of life on Krypton. The cult had Tanya, Coville's disciple who helped him learn Kryptonese, translate his journal. Coville later disappeared and was believed to have died serving Reign. Olivia then began leading the Cult of Yuda Kal. After the death of Purity and Pestilence and Reign's capture, she aimed to become the fourth Worldkiller and complete their work, using the instructions from Coville's journal.

However, Tanya grew concerned about the cult's intentions and fled with the journal, intending to take it to Supergirl. Olivia and the cult initially tried to make a Worldkiller without the journal, but failed and the heavy metal reaction killed Liza, one of the cult members. Olivia and some followers then tracked Tanya down at CatCo Worldwide Media. Inside, Olivia kept lookout and encountered James, who recognized her and was sheltering Tanya. Olivia distracted him, claiming she and Tanya got separated and weren't safe. When the cult members secured Tanya, Olivia pulled a gun on James so he couldn't interfere. As they drove off, Guardian pursued their vehicle and forced it to stop. Olivia and the followers tried to flee with Tanya on foot, but Guardian caught up to them. After a short scuffle, Olivia was able to shoot off the vigilante's mask, revealing him to be James. As some cops arrived and cornered Guardian, Olivia and the followers escaped but without Tanya. After uncovering video footage of James unmasked, Olivia and the cult sent it to him, threatening to release it if he didn't surrender Tanya and the journal at 5:00 pm.

That evening, Tanya seemingly agreed to return to the cult arrived at Pacific and 1st. After she got into the vehicle, a man named "Mike" (Mon-El in disguise) got on, mistakenly believing it to be his ride. When he realized the cult was kidnapping Tanya, they were forced to take him along.

At the ceremony, Olivia prepared the recipe for a Worldkiller as per Tanya's instructions. As she placed a Harun-El statue of Yuda Kal into the mixture, Mon-El tried to stop her, but she grabbed him, having developed the power of super strength. Olivia's eyes and veins glowed as the Worldkiller persona of Yuda Kal manifested in her. When Supergirl arrived, Olivia tossed Mon-El aside and battled the superheroine. Supergirl stated that the Olivia she saved was a good person, but the latter derided her former self as "weak." When Supergirl was incapacitated after touching the Harun-El, Olivia moved to attack her but Supergirl pleaded for her to listen, explaining she understands what it's like to feel lost and struggle with your identity. However, she stated that Olivia had so much potential, which was why she saved her. Olivia expressed that she didn't know who she was without the cult, but Supergirl assured her she had a lifetime to figure it out. Touched, Olivia tried to let go of the Harun-El but found that it had fused to her hand. Unable to touch the rock, Supergirl was forced to use heat vision to burn it off and soothed Olivia's injured hand with her freeze breath. Olivia broke down in tears, apologizing for what she did as Supergirl hugged her.

Afterwards, Olivia was taken into custody by the NCPD.

Personality
Olivia was struggling with heartbreak and depression over her boyfriend cheating on her with her best friend when she was rescued by Supergirl. Afterwards, Olivia became completely devoted to and in awe of the superhero and joined the Cult of Rao. She is a sweet, caring individual, happy to share her faith with others, and was especially close to the cult's leader, Thomas Coville, due to their similar stories. Through her faith, Olivia was able to move on from her pain and learn to love herself, as Supergirl's rescue reminded her that she had a purpose in the world.

However, Olivia's faith soon began to blind her, as she started encouraging other people, including her new boyfriend, to put themselves in danger and see if Supergirl saves them. She was even willing to let Coville endanger a stadium full of people so they would be rescued by Supergirl and join the cult, though only because she was genuinely confident that Supergirl could save them. Upon seeing Supergirl cut her hand and bleed when weakened by Kryptonite, Olivia was horrified and devastated, her faith having been broken.

Olivia grew disillusioned with Supergirl, whom she started to regard as a "false god", and felt lost and unsure of herself. In this vulnerability, she fell under Coville's influence and began worshipping Yuda Kal, believing it was her destiny to become the fourth Worldkiller. Olivia grew fanatic and ruthless, determined to accomplish her goal to carry on Reign's work through any means necessary, including forcing Tanya's cooperation, blackmailing James Olsen or even threatening civilians.

However, Olivia's misguided actions in the name of the Cult of Yuda Kal were simply an attempt fill the hole in her life, as she was unable figure who she was since losing faith in the one who originally enlightened her. When Supergirl reminded Olivia that she had so much to offer the world and becoming a vessel for Yuda Kal would just destroy it, Olivia was deeply moved and realized her mistakes. She willingly abandoned her Worldkiller mantle, distraught at who she had become.
