Egg-Wily Machine X

The Egg-Wily Machine X is a robot built by the combined efforts of Dr. Wily and Dr. Eggman during the events of the Worlds Collide storyline. It serves as the final boss for the crossover.

Visually and fittingly, the Egg-Wily Machine X is a combination of two of the doctor's prior robots. The skull head, tail and part of the feet come from Wily Machine 9 while the main body, mustache and arms are repurposed from Eggman's Death Egg Robot.
