Marvel Verses DC: Raging War is a video game about the clash of the two comic universes in an epic battle for everything.
Doctor Octopus is testing out his Multi-Dimensional Destroyer, when the Avengers arrive to stop him, but they are defeated and Ock continues on his plan. The X Men arrive, and so do the Fantastic 4. They provide resistance, and disable the device. But, Ock turns it up, ultimately destroying the two universes (this one and the other one he planned to destroy: DC), and merges them, creating a new one. Now, the Venom Symbiote has fused with Carnage and Toxin and has infected superheroes everywhere. Iron Man created a new "Anti-Symbiote Armor" and gave a copy to the following heroes: Captain America, Hawkeye, Thor, Hulk, Spider-Man, Wolverine, Silver Surfer, Batman, Superman, Flash, Captain Marvel, Green Lantern Hal Jordan, Aquaman, and Daredevil. He also encased the Hellicarrier with a special force field.
