Nightmare

NIGHTMARE

With the laboratory staff killed or copied and the laboratory itself fully infected, Samus had to work her way through the facility and wipe out every X-Parasite she could find, immune thanks to her new Metroid DNA. Along the way, she encounters a number of other escaped experiments, including a tortured creature capable of manipulating gravity.

This is the Nightmare, a biomechanical life form engineered by the Federation and taken over by X-Parasites. It would appear again aboard the Bottle Ship in Metroid: Other M alongside other classic bosses.

As a fighter, the Nightmare will be light and floaty, using its gravity powers to full effect on its own stats. Its moveset would pull from most of its battles in both Fusion and Other M.

Likelihood rating: Never gonna happen.
