Dr. Doom has seemingly destroyed the Ultimate Alliance with the Tesseract and Odin's power and is now using them to conquer Earth and corrupt the remaining heroes who attempted but failed to stop him. Unknown to everyone, the heroes of the Ultimate Alliance were saved by Uatu the Watcher who tells them the only way to defeat Doom is to acquire a piece of the M'Kraan Crystal from the Shi'ar empire and steal the Cosmic Control Rod from Annihilus. The Ultimate Alliance, joined by the Silver Surfer & Ghost Rider, rush to gather both items and take down Doom before his unrestricted use of the Tesseract and Odin's power destroys the universe.
Based on Marvel Ultimate Alliance & Marvel Heroes (Online Game).
