She's Tricked As Supergirl By Lex

When Supergirl crash landed on Earth, she was found quickly... by Lex Luthor. Ever since the beginning of his Rivalry, he would keep an eye on outer space, incase any kryptonite got close to Earth that he could grab once it landed. He didn't expect for an Alien space pod to arrive instead.

When he first saw the photo of it, he was ecstatic. It was likely another Kryptonian. One that he could raise to hate Superman and one day take him down. When he opened it up though, he saw a fully grown women. At first, he was furious. He assumed the new Kryptonian wouldn't be someone he could turn against Superman. If anything, he might have another enemy to deal with now.

He very quickly learned how wrong he was. Kara, he found her name through a translator she had, was gullible and broken. She was new to the planet without any family besides Superman. She quickly latched onto Lex. The first person who showed her kindness and gave her a place to live and even a job at Lex Corp.

It didn't take long for him to see how he can use this to his advantage. Superman would be less likely to get in his way if Kara was dating him. If he got her pregnant, he could even raise the kid to hate Superman. Of course, there was the added benefit that Kara was very attractive. He deserved a wife like her. Powerful, hot, and extremely loyal.

It was clear that Kara liked him, and though he wouldn't admit it to others, he liked her back. Despite that, he wasn't going to take things slow and treat the relationship as normal. He'd lie and trick her. Slowly corrupting her to be more and more perverted and become more obsessed with him.
