History
Baron von Widemouth was a member of the Nazis active during World War II. By the summer of 1943 he had been captured and placed in a concentration camp as a prisoner of war in Brazil. Breaking out, the Baron sought his fellow spies near the Panama Canal, executing a plot to blow up the nearby American base. Using remote control model airplanes containing Lewsite gas to knock out the American anti-aircraft sentries, they would then send a following wave of models loaded with explosives.
His plot was discovered when Steve Rogers and James Barnes caught one of their planes and then tracked through the jungle to where Baron von Widemouth and his men were hiding. During the clash, Bucky was captured by the Baron and his men, however managed escape by hitching a ride on the remote control plane armed with explosives, bailing just as Captain America blew it out of the sky.
Catching up with Baron von Widemouth, another fight ensued, culminating when Captain America threw him into his supply of explosives. The resulting impact triggered an explosion, killing von Widemouth.[1]
