Toad Man (トードマン Tōdoman) is an agricultural Robot Master that was created by Doctor Mikhail Cossack for irrigation of crops during periods of drought. When Dr. Wily forced Dr. Cossack to fight against Mega Man in Mega Man 4, Toad Man was modified for combat. His Special Weapon, the Rain Flush, is an unavoidable attack based on his original rain-making technology, that can summon deadly acid rain to a wide area.
