Bat Bone, known as Batton Bone in Japan, is a variety from Mega Man X: Command Mission that appears in the Lagrano Ruins. They initially only observe the battles they appear in, but will attack with sound waves when one ally is destroyed. Run away in its third turn without taking damage. The message "When you face many enemies, use the R2 [Action Trigger]" only appear when X has lv 1 or lv 2 and face in battle at least 2 Bat Bone.
Batfighter, known as Batton Eater (バットンイーター Battonītā?) in Japan, is another variety from Mega Man X: Command Mission with red wings and green eyes that appears in the Gimialla Mine. Unlike the Bat Bone, the Batfighter is more aggressive and attacks with bites that drain energy, recovering its health. It can also cause Berserk status.
- Interestingly, Batton Bones appear in Rockman & Forte: Mirai Kara no Chousensha, in Aircon Man's stage. Given that the Robot Masters of this game come from the future, it could explain the presence of the Batton Bone.
- The only game in the X series in which Batton Bones and/or variations of them are absent is Mega Man X3.
