No one knows what to make of the mysterious new NetNavi Bass, but everyone is intruiged when it seems that he alone can resist the CyberBeast that's slowly destroying the entire Cyber Network!

The Grave VirusBeast continues absorbing the internet. Lan and his friends team up with former WWW members to try and stop Grave. However, Mr. Gauss and MagnetMan intervene, and a strange bug left behind by Bass in MegaMan's system begins to consume him. Meanwhile, Bass attempts to absorb the VirusBeast, but is himself absorbed instead.

At last MegaMan comes face-to-face with the terrifying Grave VirusBeast that's devouring the entire cyber world... and unless it can be stopped, the network will be destroyed and Mr. Wily will control the world!
