Fictional character biography
Master Mold was created by Dr. Bolivar Trask during the original run of X-Men comics. Fearing superhuman mutants such as the X-Men, Trask makes Master Mold, a super-computer in the shape of a giant robot, that will control and facilitate the construction of the Sentinels (mechanical warriors programmed to hunt and capture superhuman mutants). Secretly, the original Master Mold is also programmed by the time-traveling Tanya Trask (Madame Sanctity), part of the Askani Sisterhood, with the mission to find and destroy The Twelve: a group of mutants that are linked to the rise of Apocalypse. Master Mold has Trask captured, and decides to take over humanity to keep it safe.

The original Master Mold is eventually destroyed when Trask sacrifices himself by causing an explosion to prevent the Sentinels taking over humanity, but several other Master Molds are later built by other people who want to manufacture Sentinels. In the late 1980s, the remains of Master Mold merges with Nimrod, an advanced Sentinel from the future, thanks to the Siege Perilous to form the humanoid being Bastion which acts like an almost-human Master Mold during the late 1990s and early 2000s.

Another Master Mold appeared in The Incredible Hulk Annual #7 and claimed to be Steven Lang who was thought to be dead after Project Armageddon. It said that Lang did not die immediately from the crash of his flying gunship; he managed to pull himself out of the wreckage and crawl to his greatest weapon, Master Mold, which merged with Lang when he tried to activate it. The computer suffered great damage by the Hulk who was with Angel and Iceman in Master Mold's meteor space base and was completely destroyed when the base exploded, after the trio manages to escape.

Master Mold also claimed the name and identity of Stephen Lang during a story arc Marvel Comics Presents #17–24, later reprinted in the graphic novel Cyclops: Retribution: Master Mold creates the Retribution Virus, designed to wipe out mutant-kind. It blames Cyclops entirely for its death as Stephen Lang. He hypnotizes Moira MacTaggart and uses her to unleash the virus, infecting Cyclops, Callisto, and Banshee who is completely incapacitated. However, 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, though weakened from the effects of the disease, nearly single-handedly destroys the Master Mold before finally succumbing to his illness and falling unconscious. As Master Mold prepares to kill Cyclops and finish unleashing the virus, he is suddenly attacked by a 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.

Another Master Mold is built in secret in the jungles of Ecuador. This particular Master Mold builds a new breed of Sentinels, known as Wild Sentinels, which are capable of assimilating non-organic materials to assume different shapes, most of them insectoid, as well as a breed of Nano-Sentinels. This Master Mold is taken over by Cassandra Nova who uses the Wild Sentinels to destroy Genosha and in her subsequent plan to destroy the X-Men. Following their defeat at the hands of Rogue's X-Men team, the Children of the Vault escaped and regrouped in the Ecuadorian Master Mold.

In X-Men: Second Coming, X-Force travels to the Days of Future Past timeline where there are two Master Molds, one of them producing Nimrods and another one protecting the first Master Mold.

After the latest Tri-Sentinel was destroyed by an Isotope Genome Accelerator duplicate of Spider-Man, Mendel Stromm was approached by a mysterious benefactor who began to give him a Master Mold that specializes in creating Tri-Sentinels. After the two Spider-Men reunite into one body, Spider-Man was able to take remote control of the Tri-Sentinels and send them back to the Master Mold base to destroy it.

In the pages of "House of X and Powers of X", Orchis creates the Mother Mold, a Master Mold variant designed to create other Master Molds. It is later revealed that the Mother Mold will be the Sentinel generation that lead directly to the creation of Nimrod.

Capabilities
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.

Ultimate Marvel
The Ultimate Marvel Universe equivalent of Master Mold are two individuals:
 * The first equivalent has a possible future where Wolverine is used as an original template to create an army of Sentinels which share his personality traits. However, present day Rogue and Wolverine discover the mutilated body and he asks them to kill him to cease the production.
 * The second equivalent is William Stryker, Jr. utilizing mutant power to infuse some of his brain patterns on the new Sentinels to build a giant Sentinel called Master Mold which houses his mind.

Weapon X: Days of Future Now
In the alternate reality of Weapon X: Days of Future Now, one of Madison Jeffries' Boxbots dubbed Bot becomes the new Master Mold and traps Jeffries within its body to use his powers to build new Sentinels without exhausting Jeffries.

What If?
In What If? Age of Ultron series set in an alternative future, Wolverine, the Hulk, Peter Parker and a Ghost Rider travel to the Savage Land to confront Ezekiel Stane using a surviving 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 the 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 this Master Mold ultimately destroyed.

X-Factor Forever
In X-Factor Forever Master Mold, Master Mold is bonded to Cameron Hodge by Apocalypse to form Master Meld.

Television

 * Master Mold appears in X-Men: The Animated Series, voiced initially by David Fox in the first season and by Nigel Bennett in the fourth season. This version was developed by Bolivar Trask and Henry Peter Gyrich at their Genoshan facility via a hydroelectric dam. While Storm floods the facility, Trask and Gyrich relocate to a secret Washington, D.C. facility to complete Master Mold. However, the two lose control as Master Mold kidnaps Robert Kelly and dozens of world leaders in an attempt to replace their brains with computers and bring them under his control as well as kill humanity upon concluding that they are also mutants, only to be foiled by Professor X and Magneto. However, Master Mold's head survived and commissioned Sentinels to help create a new body for himself as well as kidnap Trask and Gyrich for betraying him along with Professor X to graft as a new body and take his captive's powers. The X-Men eventually rescue the captives while Morph seemingly destroys Master Mold's head. In two possible dystopian futures, Master Mold has taken over the Earth, placed mutants in concentration camps and has Nimrod as an enforcer.
