The Master Mold is an immense Sentinel robot, at least thirty feet in height, which, like all Sentinels, is dedicated to the capture and destruction of superhumans. The original Master Mold was created by the Sentinels' inventor, Dr. Bolivar Track, who believed that a superhuman mutant race was evolving, that would eventually subjugate humanity if it were not stopped. Dr. Trask designed the original Sentinels as robot warriors that would hunt down and capture superhuman mutants on normal humanity's behalf. Trask created the enormous Master Mold primarily as a computer that would control the automated process of constructing other Sentinel robots. However, Trask also made the Master Mold mobile and capable of speech and equipped the Master Mold with powerful weaponry. The Master Mold could project a disintegration beam or intense electrical energy from its fingertips.
