Reign (Supergirl)

"You are no god, just as I am no devil. All I am is truth. And judgement. And death. And I will REIGN."

- Reign defeating Supergirl in their first fight Samantha "Sam" Arias, also known as Reign and by her title "Worldkiller", is the main antagonist in Season 3 of Supergirl. She is a powerful Kryptonian who was sent by her creators to Earth prior to Krypton's destruction, before growing up to be a mother to her daughter, Ruby. She later discovers her identity and unknowingly becomes a vigilante to spread justice by killing criminals and destroying anything in her path, putting her into conflict with Supergirl.

She is portrayed by Odette Annable.

Origin
On the day of Krypton's destruction, a group of hooded figures placed Samantha, as a baby, in a Kryptonian escape pod and sent her to Earth, saying that she would grow strong there and that she would then reign. When she arrived on Earth.

When her pod landed on Earth, Patricia Arias found her, took her in and raised her as her daughter. At some point prior to turning 18, Samantha became pregnant and after being forced to choose between her life at home and her child, she chose the child, before being kicked out of the house by her adoptive mother and the two of them never spoke since. She eventually had the child and named her Ruby. Unbeknownst to Sam, her pregnancy also delayed her manifestation into the Kryptonian Worldkiller, "Reign".

Learning her powers
Samantha attended the Supergirl statue unveiling by Lena Luthor with her daughter, Ruby. She encountered Alex Danvers there when Ruby ran into her and Samantha made Ruby apologize for it. During the attack at the unveiling, a metal bar fell on Ruby. Samantha, frantic and desperate to save her daughter, lifted the intensely heavy beam, much to her surprise.

That night, she went to bed, but woke up after having a nightmare of Alura Zor-El turning into a hideous monster.

Samantha drove Ruby to her school the next day, and while they waited in the car, Ruby questioned her about what happened at the unveiling. Ruby believed that her mother had superpowers, but Samantha explained to Ruby that it was nothing more than an adrenaline rush, caused by seeing her daughter in danger, and that it happened to a lot of mothers. Ruby didn't believe her, and continued to insist that Samantha had superpowers.

Later that day, moments before entering a meeting, Sam was called by the principal of Ruby's school, and was informed that Ruby had been in a fight. When inquired, Ruby informed her mother that she got into the fight because a girl in her school called her a liar for saying that her mother had superpowers. Samantha tried to convince Ruby again that she didn't have powers, which caused her to yell at Ruby only for her to run off. Sometime afterwards, Samantha received delivery pizza and took it to Ruby's room, only to find her gone.

She messaged Ruby and asked her where she was, and Ruby told her mom, her location. Samantha ran out and found Ruby in the midst of an attack by the telepathic Psi, and moments before they were crushed by a wrecking ball, Supergirl saved them. Samantha talked to Ruby after the attack, and realized that Ruby wanted her to have superpowers so that she wouldn't have to work, and could just save people and spend time with her. Samantha then reassured her daughter that she would always spend time with her, no matter what.

Working at L-Corp
Later that day, she appeared at CatCo where she met Kara Danvers, and revealed that she was hired at L-Corp to be the acting CEO while Lena Luthor adjusted to her new business. At home, Samantha had trouble sleeping and, while searching for light bulbs, found a crowbar. She remembered what her daughter had said and tried to bend it, but failed in doing so, slightly convinced that she did not have superpowers.

Samantha attended one of Ruby's soccer games, and proudly cheered her daughter on from the sidelines. She took a call during the game, and as she was talking, Ruby scored a goal and asked her mom if she saw it, and Sam covered by shouting that she did and that Ruby did a great job. A woman walked up to her and asked which child was Sam's, and Sam pointed her daughter out and jokingly stated that she wasn't sure how Ruby was so coordinated since she herself isn't. She asked the woman which child was her's, but the woman reflected and stated that Ruby was special and was chosen - they both were, and handed her a flyer for a meeting. Sam asked for the lady's name, and the woman stated that she was a follower and asked her to bring Ruby to the community. Sam forced a smile and thanked the woman who walked out.

Lena and Kara arrived at L-Corp moments before Sam walked in. She then told Lena that the latest major merger should be finalized any minute and handed the papers to Lena, who signed them. Lena asked how she was planning to celebrate her first big merger as CEO, and Sam just chuckled. Kara invited Sam to her girls' night, and she initially declined but after being pressed a little more by both Lena and Kara, she agreed to attend. She asked what to bring and Lena told her to bring booze - but not tequila. Kara found the flyer the woman from Ruby's soccer game gave her and asked her about it, and Sam told Kara what had happened and let Kara take the flyer.

Personality
Although Sam is a single mother, she does her very best to support her daughter, Ruby, who is the most important person to her in the world. She is very nice and caring, and has a motherly air to her. She is also a very strong woman, and can hold her own in mental battles against businessmen such as, Morgan Edge. She has a high intellect, and has enough business knowledge to run L-Corp flawlessly.

As Reign, Sam has become cruel, sadistic and ruthless towards anyone who stand in her way.
