Wily Star

Wily Star (ワイリースター) is the starbase that Dr. Wily hides out in Mega Man V. It has a giant skull called Skull Blazer (スカル・ブレーザー) in the center that attacks with large lasers. The four cannons above the skull launches guided missiles, and the four lower ones normal shots. Wily Star can only be damaged when the mouth of the skull is open, and Mega Man enters in it with Rush after destroying the mouth. Inside it, Mega Man fights against Enker, Quint, Punk, Ballade, eight Stardroids, Dr. Wily, and Sunstar. After defeating Sunstar, the Wily Star explodes.

In Mega Man: Upon a Star, a starbase similar to the Wily Star appears in the second episode. It is unsure if this is the Wily Star, however.

Trivia
Wily Star is an obvious parody of the Death Star in Star Wars.
