Thirty years ago, Duo's comet had crashed on Earth, and Dr. Regal plans to travel through space and time to absorb its power. MegaMan, ProtoMan, SearchMan, and Colonel rush through time to thwart Dark MegaMan who was sent to help Dr. Regal gain access to the comet. However, Dark MegaMan plans to absorb the power himself and become the ultimate NetNavi, but Slur refuses to allow him to do so by deleting him. Before fading away, Dark MegaMan self-destructs and prevents Dr. Regal from succeeding. The heroes return home, and the renmants of Dark MegaMan's being rejoin with MegaMan's soul, and MegaMan forgives him.

Duo begins to erase the Earth, and in order to stop him, all thirteen CrossFusion Members must join together. However, Baryl has already died. Dr. Wily of the past works with Dr. Wily of the future to send Baryl through time and space using the Spectrum program. Once Baryl arrives in Lan's time, he receives a SynchroChip and uses CrossFusion to help his allies take down another invasion of Asteroids.

Bass reappears and now infused with the power of Nebula Grey, he deletes Slur. Meanwhile, Dr. Regal gains access to Duo's power and begins his attack on Earth, but Duo kills him before beginning the erasure of Earth. The CrossFusion Members travel to Duo's comet, avoiding demise as the Earth vanishes. They confront Duo, begging him to reverse the erasure, but Duo cannot comprehend their pleas, having more interest in CrossFusion instead, a technology similar to his own race's.
