Batton Bone (バットンボーン Battonbōn?) is a common enemy Mechaniloid appearing in the Mega Man X series that is the successor of the Bubble Bat from the original Mega Man series. They behave pretty much like their predecessor, mainly acting as aerial obstacles and inflicting damage if physical contact is made. The only difference is that they can be damaged even while hanging inactive upside down. The Batton Bone's first appearance in the series is in Armored Armadillo and Chill Penguin's stage from the first Mega Man X game.
