Many long-time fans of Marvel and Dc have posed the very interesting question: if the Marvel and Dc Universes merged, what would it look like, and who would make up the teams? That means which characters would make up the line-up of the Justice League, the Avengers, the Teen Titans, and so on.
Note: This is NOT an Amalgam Universe. All of the characters would stay themselves, the team line-ups would just be different.
Also, if anyone wants, short stories can be written around these new line ups, as well as how the two universe merged in the first place.
So, without further a-do, get imagining!
