The original version of Master Mold was created by Dr.Bolivar Trask during the original run ofX-Men comics. Fearing superhuman mutants such as the X-Men, Trask makes a super-computer in the shape of a giant robot that will control and facilitate the construction of theSentinels (mechanical warriors programmed to hunt and capture superhuman mutants). Secretly, the original version was also programmed by the time-travelingMadame Sanctity of the Askani Sisterhood with the mission to find and destroy The Twelve, a group of mutants that are linked toApocalypse's rise.^[1] Master Mold had Trask captured, and decided to take over humanity in order to keep it safe. The original Master Mold prototype was eventually destroyed when Trask sacrifices himself by causing an explosion to prevent the Sentinels taking over humanity (but several other versions are later built by other bigots who want to manufacture Sentinels).^{[volume & issue needed]}

Another version of Master Mold hadSteven Lang's brainwaves. After Project Armageddon, Lang tries to activate Master Mold which merged the former's mind with it instead. The computer suffered great damage by theHulk who was withAngel andIceman in Master Mold's meteor space base and was seemingly destroyed when the base exploded, after the trio manages to escape.^[2] However, Master Mold survived and creates the Retribution Virus to wipe out mutant-kind. It blamesCyclops entirely for its "death" as Lang. He hypnotizes and utilizedMoira MacTaggart to unleash the virus, infecting Cyclops,Callisto, andBanshee before MacTaggart breaks free of his grasp. While she attempts to cure the virus, Cyclops and Callisto team with Conscience (another artificial construct developed from Lang's brain engrams) to stop Master Mold and save mutant-kind as well as all humanity, which had become threatened by the virus. Cyclops was weakened from the disease's effects but nearly single-handedly destroys Master Mold before finally succumbing to the illness and falling unconscious. As Master Mold prepares to kill Cyclops and finish unleashing the virus, he is suddenly attacked by the cured Banshee who uses his sonic scream to "finish the job that Cyclops started" and destroys Master Mold. The virus is then cured before it has a chance to spread.^[3][4]

The remains of Master Mold later merge with the advanced SentinelNimrod from the future thanks to theSiege Perilous to form the humanoid cyborgBastion which acts like an almost-human version of Master Mold.^{[volume & issue needed]}

A Master Mold-esque factory is built in secret in the jungles ofEcuador. This particular version builds theWild Sentinels which are capable of assimilating non-organic materials to assume different shapes, such as an insectoid, as well as a breed of Nano-Sentinels. The Wild Sentinels are taken over byCassandra Nova to destroyGenosha and in her subsequent plan to destroy the X-Men. Following their defeat byRogue's X-Men team, theChildren of the Vault escaped and regrouped in this Ecuadorian location.^{[volume & issue needed]}

InX-Men: Second Coming,X-Force travels to theDays of Future Past timeline where there are two Master Molds, one producing Nimrods and another one protecting the first Master Mold.^{[volume & issue needed]}

A new version calledMother Mold is seen in "House of X and Powers of X".Orchis creates a variant designed to create other Master Molds.^[7] It is later revealed that Mother Mold will be the Sentinel generation that lead directly to the creation of Nimrod.^[8]

Dr. Bolivar Trask equipped Master Mold with powerful weaponry and the ability to speak; Master Mold was also mobile so that it could defend itself from mutant attackers or so that it can be relocated easily if Trask had to find a new headquarters. The Steven Lang Master Molds were also capable of self-repair.

InWhat If? Age of Ultron series set in an alternative future, Wolverine, the Hulk, Peter Parker and a Ghost Rider travel to theSavage Land to confrontEzekiel Stane using Master Mold to reproduce Iron Man armors. Stane uses an unnamed girl, described as an orphan, the sole remaining Trask descendant, and referred to only as 'Ms. Trask', to operate Master Mold that had apparently been left behind in the Savage Land. Seeking to unleash a wave of the armors upon the world, Stane is stopped, and Master Mold ultimately destroyed.^[13]
