I am a massive fan of Flash, Arrow, Legends of Tomorrow and Supergirl

Recently it was announced that the long awaited Supergirl/Flash crossover was finally going to happen and I among other fans where so excited that this was finally going to happen.

I think I wanted this to happen more than any other fan, I even went as far as to start a petition to make Supergirl and The Flash crossover, the petition can be found in my previous post, don't bother signing because we don't need it now that the crossover is happening.

The Flash and Arrow executive producers had been wanting the two shows together since the beginning, but CBS president Nina Tassler before stepping down, didn't want the two shows to crossover at first, stating she wanted to 'keep Supergirl to themselves for a while'.

I was upset and angry at her as having Supergirl and The Flash not crossover is like having 4th of July without Fireworks or a Friday with no four pizzas.

But luckily there is a crossover coming but there remains one question....

Are they in the same universe??????

Grant Gustin recently posted the Title page of the script for Supergirl which was titled 'Worlds Finest', this has left fans confused for a few reasons.

  • 1) The word Worlds usually means more than one world, which means Barry could travel to Kara's world.
  • 2) It could've been put there to let the fans think whether or not they exist in the same universe.
  • 3) Barry could travel to the future where Superman and Supergirl have been introduced.

To be honest I think it would be better if Supergirl and The Flash existed in the same universe, because it would mean we would see Barry and Kara team up more, and Oliver and the Legends of Tomorrow would also be able to team up with them.

But I also don't mind if they don't exist in the same universe because I think the CW and CBS will find a way for them to exist in the same universe so that they can have more crossovers without the whole dimension travel thing. Like Barry, Kara, Rip Hunter, Constantine and other powerful Superheroes could team up and have a Flashpoint event that creates a whole new universe that has The Flash, Green Arrow, Legends of Tomorrow, Constantine and Supergirl exist in the same universe.

But that's my opinion, if you have a different opinion, please post in the comment section, thank you for reading.


Should Supergirl exist in the same universe as The Flash?
