Heroes from Marvel and video game company Capcom join together to take on a new threat in the latest cinematic trailer for upcoming fighting game crossover, Marvel vs. Capcom: Infinite.

The clip, released Thursday, explores the game's story mode and how the title's new pair of villains, Ultron of Avengers fame and Sigma from Mega Man X fuse together to become a more powerful being.

Things become more dire as Ultron Sigma begins to collect the all-powerful Infinity Stones. The cast of heroes including the likes of Marvel's Iron Man, Captain America and Spider-Man and Capcom's Chun-Li from Street Fighter, Chris Redfield from Resident Evil and Mega Man X, then turn to the villainous Thanos for help.

It is then that Captain America and Iron Man find themselves squaring off against each other as Iron Man disagrees with Captain America's plan to release Thanos from his captive prison.

New playable characters, including Ghost Rider, Doctor Strange villain Dormammu and Capcom's Jedah, Firebrand and Nemesis from Resident Evil, also make appearances in the trailer.

"Ultron Sigma has obtained two Infinity Stones and fused the Marvel and Capcom universes. Jedah has conspired with other villains to create a ravenous Symbiote beast. Can our heroes trust Thanos to lead them to the remaining Infinity Stones and beat back these threats? The clock is ticking, and all reality is at stake," reads the synopsis.

Marvel vs. Capcom: Infinite is set to launch for the Playstation 4, Xbox One and PC on Sept. 19.
