Ground Man (グランドマン Gurandoman?) is one of the first three selectable bosses in Mega Man & Bass, alongside Astro Man and Cold Man. He is a Robot Master created by King to excavate ruins, but sometimes hoards treasure that he finds for his own personal collection without consulting his leader. He likes excavating with passion and only stops when ordered to do so. He's said to be the most powerful robot from King's army. Ground Man is a deep thinker, but hardly ever speaks and is very unsociable. His main weapon is the Spread Drill, a drill-like missile that can separate into smaller drills. He can also transform into a small drill-shaped machine, being invincible during the attack, and uses a giant drill when in the ceiling.
