After the battle between Gregar and Falzar in episode 24 of Rockman.EXE Beast, the Lord Wily of Beyondard uses Trill to combine Falzar with Gregar, creating the Super Cybeast Galzer and using it as his vessel. With his new body, Wily attacks both worlds. Galzer and Wily (seemingly) were deleted by MegaMan in episode 25, and the Fossa Ambience is closed.

Galzer was defeated once again by MegaMan then go back to data world.

With its new powers, the creature is able to appear in the real world and begins to absorb the Earth, growing to insane sizes. MegaMan and Bass fight against it to save the world.
