Skull Castle

Skull Castle is Dr. Wily's fortress and base of operations on Megaland. It seems to be inspired by the Wily Castle from Mega Man 3, and includes an underwater chamber that releases robot turtles.

Duke and Rush were imprisoned in Skull Castle as part of Dr. Wily's plan to hijack the Peacekeeping Robot. After Kevin Keene and Mega Man rescued their dogs and escaped from Doc Robot, they were sneezed out of the castle.
