Dr. Bolivar Trask, the creator of the mutant hunting robots known as the Sentinels, created the Master Mold a self-aware model which would be tasked with constructing more of the massive robots.

Master Mold eventually determined that the only way to fulfill its mission of eradicating all mutants was to enslave humanity. Trask was forced to sabotage his own program thereby destroying himself as well as the Sentinels.

Years later the remains of the Master Mold were found and reassembled by Dr. Steven Lang, who was working under the direction of the Council of the Chosen, the precursor of the Inner Circle of the Hellfire Club. Lang also created legions of Sentinels to attack the X-Men, but their construction was inferior and he was defeated and apparently died.

Programmed with Lang's mental engrams, Master Mold was activated and began to believe that it was Lang. Obsessed with the eradication of mutants Master Mold was dauntless and always returns despite being destroyed numerous times.
