M.O.D.O.K. BUILT A ROBOT BUCKY BARNES TO KILL CAPTAIN AMERICA — AND PROGRAMMED THE LOYALTY IN TOO WELL TO FINISH THE JOB!

The Featured Fact

In 1970, Captain America got the one headline he had prayed for and dreaded in equal measure: Bucky Barnes, his wartime partner, presumed dead for decades, was back. The reunion was a fabrication. The returned Bucky was an android duplicate deployed by M.O.D.O.K. — with some accounts crediting Doctor Doom's workshop for the machine itself — built to get close to Cap and kill him.

The scheme collapsed on a workmanship problem no A.I.M. quality review could have caught: the duplicate had been programmed too faithfully. Given Bucky's memories and devotion along with his face, the robot found itself unable to murder the man its template had idolized. Faced with a weapon that refused to fire, M.O.D.O.K. destroyed the android himself rather than let it walk around embarrassing the brand.

The story ran as "The Fearful Secret of Bucky Barnes!" in Captain America Vol. 1 #132 (December 1970), by Stan Lee and Gene Colan, and spilled into #133, where M.O.D.O.K. fell back on a blunter instrument — an android called Bulldozer, hurled at Harlem to draw Cap and the Falcon out — while flashbacks finally laid out how technician George Tarleton had been remade into the Mental Organism himself.

Why It's Obscure

A resurrection that was really a product launch, recalled for excessive loyalty.

1970

The return — Captain America #132 announces Bucky Barnes alive, and the fine print reads: some assembly, and one assassination, required.

The flaw

Too well made — copy a sidekick's heart along with his face and the copy inherits the one instruction that overrides all the others: protect Cap.

The recall

Quality control — M.O.D.O.K.'s fix for a defective assassin is immediate and personal: he scraps it himself.

Doom

The subcontractor — synopses of the tale credit Doctor Doom with building the duplicate M.O.D.O.K. deployed; even Latveria's finest could not debug devotion.

#133

The sequel — one issue later the subtle weapon is shelved for an android literally named Bulldozer. Subtlety had its chance.
