Karadox

Karadox is the het ship between Kara Zor-El and Querl Dox from the Supergirl fandom.

Season 3
THE LEGION OF SUPER-HEROES

Kara wakes up in her loft, hearing a knock at the door. She opens it to reveal Querl standing there, talking nervously about meeting her. Kara is very confused by his comments till he calls her Supergirl. She immediately pulls him into the loft telling him to be quiet. He officially introduces himself as Brainiac 5, otherwise known as Querl Dox, but that the Legionairs just call him Brainy. He informs Kara about what's going on. Specifically that she's been in a coma after being nearly killed by Reign, and that he's hear to help her wake up. She becomes panicked and tries to open the loft door repeatedly, becoming more frustrated with each try. Brainy suggests that she relaxes, but she ignores him.

Brainy looks around the loft while Kara sits on the couch. She asks why he's looking around, and he explains that he's checking for brain damage, which would manifest itself as damage in the loft. He needs to check to make sure she's ready for reality re-entry. Kara asks if that means she is ready to wake up, Brainy confirming so. She asks what she needs to do to get out of the coma, Brainy coming to the conclusion that opening the loft door is the most likely exit. She tries the door but it doesn't open. Brainy then tries the door, but it doesn't open for him either. This confuses him, since she should be fine.

Kara continues trying to open the door, as Brainy makes tea in the kitchen. He comes to the conclusion that Kara not being able to wake from her coma is a mental problem and not a physical one. Kara punches the door, while Brainy asks if there would be any reason as to why her subconscious wouldn't want her to leave, suggesting self preservation. Kara doesn't believe so, but Brainy reminds her that she was badly beaten, and that fear would be a logical response. She then uses her heat vision on the door, Brainy staring at her, as she destroys the room around her.

Kara starts cleaning the loft, Brainy asking why, since it's not real. Kara doesn't know, only that she like putting things back in order. Kara realizes that she chose everything in the loft, and that there's probably something in there that her subconscious wants her to see. Brainy say that it isn't a bad idea, and wonders why he didn't think of it. Kara then begins to search through her stuff.

Kara eventually finds a picture of herself and a black cat. Brainy asks if that was her pet, Kara says yes, but quickly wonders why her subconscious would want her remember her cat. Brainy says it could be a random neuron firing and asks the name of the cat. Kara named him Streaky and that he had been a stray like her. Brainy asks if she had felt an emotional connection with the cat. Kara says yes, she and Streaky were friends. Streaky suddenly appears in her loft. As she walks over to him, she explains how she used to feed him every night, but was so scared to touch him due to her super strength. She had practiced being gentle, until she was confident that she wouldn't hurt him. She then pet him, and he purred, the act making her feel human, instead of like an alien.

Brainy accidentally talks about the battle against Reign while in Kara's head. He tries to brush it off, wanting her to keep talking to keep his mind off the battle. Kara says that he should be entirely focused on the battle. Brainy says he's capable of doing both, but shows his strain when he stops mid sentence to tell Mon-El to evade one of Reigns attacks. Kara tells him to go help the legion instead of her. As he's about to leave, he says that it looked like Supergirl had a great life. Kara says that, the stuff in the loft weren't Supergirls, but Kara Danvers'. Brainy tells her how Alex said something similar. Specifically that Kara Danvers was her favorite person. He leaves to join the battle, Kara thinking over his words. She then wakes up and fights Reign alongside the Legion and J'onn.

After she checks on Mon-El and Imra, Brainy walks through the DEO in her direction. Kara see's him and says hi, then asks if he's shorter in reality. He then asks if she's suggesting that he changed his height while in her head so that she would see him as someone more stable and trustworthy, thereby making her more likely to want to work with him to help her. Kara confusingly answers yeah, and Brainy confirms that she's correct. She laughs, and he says that it's nice to meet her in real life. As he walks away she smiles at him.

OF TWO MINDS

Kara goes up to Brainy, worried about Alex and Winn, and asks if they've found anything on Pestilence. Brainy says that he looked through the security footage but was unable to track them during their time at City Hall. She asks if he looked on social media, which confuses him, since they don't have that in the future. They check, and suspect a doctor who was there. Brainy pulls up her information and J'onn, Mon-El and Kara head out.

TRINITY

Team Supergirl discovers that a way to get to Sam, but they would have to go into a different dimension to do so. Kara thinks of a way to get there, and goes to Brainy, hoping he'll use the same tech he used to get into her head to get into the other dimension. He thinks it'll be fun and leads them to the Legion ship. There Brainy tells her that taking Lena and Alex with her into the dimension will weaken her and there's not much he can do. They get ready to go as Brainy explains as the process works. Once he's done Kara tells them to get started and he sends them into the other dimension.

Season 4
AMERICAN ALIEN

Brainy and Alex are having a disagreement when there is an alert that Kara is in trouble. Alex is about to send in a strike team, but Brainy says that there is no time and flies off to her. Brainy arrives, to find Kara's legs cuffed and unable to fly. He asks if she needs some back up, followed by telling her she's freed. Kara is confused, but the cuffs then fall off her immediately. Brainy explains that he was hacking while talking to her. She stands up and smiles at him before flying away. He sarcastically says "You're welcome." once she's gone.

Kara gets a call from Brainy while at CatCo. He quickly complains about Alex "grounding" him before telling her how he found out who attacked the facility, and was able to narrow it down to Mercy and Otis Graves. She asks for an address, but he can't find one, only an ex-employer who could help. Lillian Luthor.

Kara is finishing up a meeting when Brainy calls. He tells her that the info she got from Lillian, helped him pinpoint a location, an abandoned warehouse. She flies out to find no one there, but Brainy tell her that there were heat signatures earlier, and hacks into the computers. Kara looks at the computers, filled with hate messages for aliens. Kara is horrified but is able to ask Brainy what he found out. He found Blue Prints of Camp David, meaning that the Graves are going to attack the president.

Fanon
Those who were fans of the pairing in the comics were quick to ship them in the tv series, given the canon status of the pairing in the comics. Although it would be considered a rare pair in the fandom. This is most likely due to most shippers already having a preferred pairing by the time Brainy is introduced.

After his introduction, SuperCorp shippers didn't express concern when it came to the possibility of Karadox becoming canon whereas Karamel shippers did. Shippers tended to either love or hate Brainy as well as his interactions with Kara, and it became very apparent that only the non-karamel shippers accepted the pair. Following the confirmed departure of Chris Wood (Mon-El) from the series, Karamel shippers have started engaging in online and social media hate towards Karadox, Brainiac 5 and Jesse Rath himself.
