Toad Man is one of the eight Robot Masters that appears as boss in Megaman 4. It was created by Dr. Cossack to irrigate crops during the drought of the garden. But after Dr. Wily forced Dr. Cossack to work under the death threat of his daughter Dr. Wily had abducted, the Toad Man was then modified to combat. Yours is the Rain Flush which is a capsule full of acid, capsule anger fires to the sky that will turn a rain of acid. Toad Man is able to jump very high if he is attacked before using his Rain Flush. And if this tactic is well explored it will be defeated very easily. His weakness is the Drill Bomb.
