Planet Master is the name of two fictional characters appearing in comics published byDC Comics. The first Planet Master, a scientist called Irving Norbert and his lab assistant, who would later take on the name and costume, first appeared inDetective Comics #296 in October 1961.^[1] The characters were created by writerBill Finger and artistJim Mooney.

Professor Irving Norbert is a scientist who was exposed to the gases of a meteor. The result caused him to develop a split personality, with his alternate personality turning to a life of crime. Using his knowledge of astronomy, Norbert becomes a costumed villain named Planet Master, utilizing weapons based on the nine planets. He managed to outwitBatman andRobin in the first battle. Norbert's unscrupulous assistant Edward Burke discovers the double identity of his boss and decides to either join forces with Planet Master or to use his equipment on his own. Ultimately though, the effects of the gas wear off. Norbert's criminal self is erased and Batman brings Burke to justice.^[2]

WhenKobra creates a strike-force calledStrike Force Kobra to usurpStagg Enterprises in his goal of world domination, one of the villains he recruits is patterned after the original Planet Master. What makes this version different from the original is that he can simulate the conditions of the other planets in the Solar System. He, alongside the other members of Strike Force Kobra, battles the Outsiders.^[3] Planet Master appears during theInfinite Crisis storyline as a member ofAlexander Luthor Jr.'sSecret Society of Super Villains. He participates in the Battle ofMetropolis alongside Strike Force Kobra teammatesZebra-Man and Spectrumonster.^[4]

The first Planet Master uses weapons based on the planets.

The second Planet Master can simulate the conditions typical to any of the nine planets in theSolar System. For example, he can use the speed of Mercury, the heat of Mars, the strength of Jupiter, the rings of Saturn, and the cold of Pluto.

• An amalgamated incarnation of Planet Master appears inBatman: The Brave and the Bold, voiced byStephen Root. This version resembles Irving Norbert and possesses similar powers to the second Planet Master.
• Edward Burke appears in theBatman: Arkham KnightDLC "A Matter of Family" via audio tapes, voiced byJB Blanc. This version was a billionaire whose daughter was dying of cancer. He was approached by Dr. Penelope Young, Dr.Harleen Quinzel, and theJoker under the alias of "Jack White", who claimed they would cure her while Burke built the Seaside Amusement Park as a favor to White, though Burke's daughter died anyway. Devastated, Burke gave ownership of the park to White and was driven to suicide, unaware that the pills he used were laced withJoker venom.
