Professor Irving Norbert
Irving Norbert was exposed to the gases of a meteor and gained a Mr. Hyde-type second personality. This personality became a criminal. He made weapons based on the planets. He manage to discover the alter egos of and outwit Batman and Robin, but the gas wore off and he forgot about his misadventures.
He joined Korba's Strike Force Kobra team. He battled (and was defeated by) the Outsiders.
The original Planet Master had planet-based weapons.
The second Planet Master could simulate the "abilities" of the planets. For example, he can use the speed of Mercury, heat of Mars, the strength of Jupiter, spinning of Saturn and cold of Pluto
