Grey Devil

Grey Devil (グレーデビル) is the first boss from Rockman & Forte: Mirai Kara no Chousensha. It attacks by throwing three balls of slime and sliding to the other side of the screen.

Trivia

 * The Grey Devil is the only Devil robot from the Mega Man games not featured in the Short Circuits for Issue 55 of the Archie Comics Mega Man series. Archie writers have previously indicated that they are unable to use content from Rockman & Forte, such as the Dimensions. Interestingly, the Steel Devil from the Dreamwave Mega Man series appeared instead.
 * His stage BGM is recycled from Burner Man's stage.
