barry finds out supergirl is an alien

If Barry kidnapped Supergirl in fanfiction, it could be a really interesting plot twist. Maybe Barry has been affected by some sort of red kryptonite - like substance that makes him act out of character. This would lead to a conflict between the Flash and Supergirl's friends and allies. They would be confused as to why Barry would do such a thing.

The survival of their friendship is uncertain. Oliver has a lot of pride and Barry is his friend. Finding out about the kiss could shatter Oliver's view of Barry. However, if they both value their friendship more than their feelings for Felicity, they could work through it. They might have to go through a period of awkwardness and rebuilding trust, but it's possible for their friendship to survive.

Another possibility is that Barry was kidnapped himself first and then forced to kidnap Supergirl. The real kidnappers could be a group of meta - humans who want to create chaos by pitting two of the most powerful heroes against each other. Barry would be in a difficult situation, having to do something against his will, and Supergirl would initially be confused and angry at Barry until they both figure out what's really going on.

Well, Oliver might get really angry at Barry. He could see it as a betrayal since Felicity was someone he had feelings for. He might confront Barry and demand an explanation.

Well, the plot could involve Supergirl and Barry initially meeting during a multiverse - related crisis. They might start as allies, but as they work together more often, Supergirl begins to notice Barry's kind heart and his determination. She could be drawn to his unique sense of humor as well. Their relationship might develop slowly, with them sharing their secrets and fears, and eventually realizing they have fallen in love. It could also involve some challenges like having to keep their relationship a secret from their respective teams at first.

Perhaps in this fanfiction, Barry's death causes a rift in the multiverse. Supergirl then has to team up with other heroes from different universes to try and fix it. His death could be the start of a much larger threat that only a united front of heroes can face. She might struggle with the guilt of not being able to save him at first but then turns that into motivation.

Yes, there are several. You can check fanfiction websites like Archive of Our Own. Just search for 'Barry is Savitar' and you'll find a variety of stories with different takes on the concept.

If Supergirl and Barry are in a relationship in the fanfic, their powers could interact in some interesting ways. For example, Barry's super - speed could be used to enhance Supergirl's combat abilities. He could quickly move her around the battlefield, allowing her to surprise enemies. Supergirl's strength could protect Barry when he's vulnerable during his high - speed runs. They might also combine their powers to create a sort of 'super - blast' by having Supergirl charge up an energy attack while Barry spins around her at super - speed to amplify it.

Barry may face the challenge of controlling the baby's speed powers. Since the baby is a speedster, it might accidentally use its powers in a dangerous way, like running into walls or causing chaos in the city. Also, he has to figure out how to feed and take care of a super - powered infant, which is no easy feat as normal baby - care methods may not work.

I'm not sure specifically as there could be many different interpretations. It might be a fan - made story (fanfic) where a character named Barry knocks someone out. Without more context, it's hard to say exactly.
