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 mutantkind. 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 mutantkind 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.
