The guys on the Wave Rider decide to help Alex Danvers for Christmas. Kara takes exception, and Barry's the reluctant middleman. Post Crisis on Earth X.

One-shot. After going on the ship, Mon-El doesn't fly off into space but into a portal to Earth 1 in hope that her friends there can help him. Can Starlab help him? Can he help them get Barry back? Set after last season's finale for both shows.

What if Kara and Barry were on the same Earth? What if they were brother and sister? This story focuses on Karry, a brother/sister pairing with no romance between the two! But there will be lots of violence. Because why not? May I also add in that there will be lots of adventures? UniteTheSeven (IMVU) gave me this idea, so if you ever see him around on IMVU, thank him!

Lex Luther has become president and has sent out a army to exterminate all metahumans especially the members of the justice league. (Cw shows x justice league)

The Crisis on Earth X crossover was pretty light on moments between Kara and Barry, but I decided to play around with it anyway. This is a short retrospective of their moments at the end of Supergirl 1x18 (Worlds' Finest) and during the wedding rehearsal in Supergirl 3x08 (Crisis on Earth X, Part I), with a little fleshing out of the scenes. Rated K.

The Mutliverse states that anything that can happen will happen. The possibilities are endless. Take a look as we see Barry and Kara across the Multiverse

AU where the worlds merge in World's Finest. Superflash, Reigncorp (with a not evil Sam), mentioned Sanvers and implied Olicity. Also motherly Cat. Lena, Sam, Cat, and Lois all know Kara's identity. Some characters are around some aren't around. Timeline not accurate. I might continue this, but for now, it's complete. This would be Earth-36.

My name is Ky-El. I'm the twin brother to Kara Zor-El, more commonly known as Supergirl.

My version of what happened to Earth X's Barry Allen and how the SS came about thanks to Kara and Oliver. No Nazi's in this one! Part one of Earth X AU

SPOILER ALERT! My take on how Supergirl is captured during the two night crossover event starting tonight

In another Universe, Barry Allen and Kara Danvers are best friends and in love with each other. They just don't know it yet. How will they feel when they discover that the other has been keeping an enormous secret - BIG enough to ripple time and space itself? Will it bring them closer together or tear them farther apart? {Discontinued!}

AU where Iris and Mon-el do not save Kara and Barry right after they get shot. Bad at summaries please forgive me.

AU of Supergirl Flash Musical crossover. Instead of only Mon El, Hank, and Kara coming to Earth 1, Alex also comes since she wants to help her sister. Music Meister also teaches a lesson to Mon El on what love is, and that there are different kinds of love. Also, brief but funny appearance of Maggie in the end. Kara and Mon El broke up for real.

Kara convinces Barry to stay in National City just long enough for one game night. But what no one of expecting is...dang, those heroes have got some pipes! Not-so-hidden Glee references, lots of friendship fluff, but can be read as Barry X Kara sometimes. No longer a one-shot! (New chapter: post-crossover)
