Sonic Man

Sonic Man is one of the three Robot Masters from the Mega Man computer game for DOS.

Sonic Man is an aquatic Robot Master who uses Sonic Waves that are hard to see. He also attacks with three small mines that he drops directly onto Mega Man. He is weak against Dyna Man's Nuclear Detonator weapon because of the rapid change of pressure in the water it causes. Defeating him gives Mega Man the Sonic Wave weapon.
