Frog-Man was one of the first Ani-Men, hand picked by the Organizer. The Ani-Men were soon sent against Daredevil by the Organizer, after he had crossed the Organizer's plans on several occasions. After implicating Daredevil in a bank robbery, the Ani-Men were next sent to kidnap Debbie Harris. He was defeated by the Daredevil, who stole his costume and impersonated him to infiltrate the Organizer's headquarters.
When the Ape Man, Cat Man and Bird Man renamed themselves the Unholy Three, Frog Man left the group but returned when, as the Ani-Men again, they were employed by Count Nefaria. Given genuine super powers which replicated his earlier power suit but gave him a frog like appearance, Frog Man was with the Ani-Men when they fought the X-Men and were defeated by them. Later, still in Nefaria's service, he and the other Ani-Men fought Iron Man but were apparently killed when the assassin Spymaster blew up the building they were in.
