A Merged/Hybred universe

We look to the worlds that have more than one common link to the worlds of the superhero. We look to Crossover and Amalgram universes.

The most common version of this world is the Crossover world. A place where more than one comic universe colide and combine. There are two main types. One where the universes are seperate, but touch. Wee a character from one universe enters the other universe. Like the Marvel Vs. DC or JLA/Avengers crossovers.

The other is the world were the worlds are one from the beginning. Were Spider-man's New York exist with Superman's Metropolis and Batman's Gotham. Where histories and cosmic properties combine.

The third option is the world that is also a combo of the worlds, but where heroes blend with each other. Amazon of Amalgram (Storm as Wonder Woman) or the Scarlet Lantern from the BEAddventure.

What world would you choose to live in and experience? What wonderful stories could you create with the blending?
