Captain America (1968 series) #133

Enraged at the failure of the Bucky Barnes android (in the previous issue), MODOK disintegrates his erring scientists with a mind blast. Hating Captain America because the hero is so tall and handsome, while he himself is so grotesque, MODOK vows to make Cap suffer as he has suffered. His mind goes back to his creation, when the A.I.M. Scientist Supreme ordered him, a hapless minion, placed in the Alteration Chamber, where he was transformed into a living weapon with an enormous brain, dubbed MODOK—Mental Organism Designed Only for Killing—who then used a mental blast to destroy his superiors and take over as head of A.I.M. The madman then uses his mental powers to locate Captain America and finds him in Harlem with his friend, the Falcon. MODOK and his minions redesign the Alteration Chamber and use it to create a giant android called the Bulldozer. The giant is delivered to the Lincoln Tunnel where it begins to rampage through the city, impervious to police bullets, until it reaches Harlem. Cap has just revealed his identity to the Falcon and is about to propose a partnership when the building is shaken by the Bulldozer, tearing down tenements and shouting populist slogans. Cap and Falcon try to stop the huge robot but are opposed by the watching crowds who have been duped into believing the Bulldozer is a defender of the poor and downtrodden. MODOK heads to Harlem to observe his victory in person. Meanwhile, Cap has contacted Tony Stark, who has created something that can defeat the giant robot: a jamming device that forces the Bulldozer back to its creator. Cap and Falcon trail the monster into an abandoned church where they fight MODOK. The confused android goes berserk, bringing the building down on itself and its creator. Cap and Falcon confirm their partnership to help the people of Harlem.
