Matter Master possesses a rod made out of a unique compound called "Mentachem," which allows him to control matter with a variety of effects. He is capable of performing many of these FEATS at once, at a range of one mile. The wand defies hundreds of scientific principles, so it is likely that it actually harnesses a powerful form of magic. The more common abilities of the wand include:
Chemistry * Geology
Numerology * Astrology
The Secret Society of Super-Villains
Mark Mandrill was a would-be alchemist trying to change lead into gold, when a vial of unknown chemicals exploded in front of him. Terrified, Mandrill screamed, "Stay away from me!" and to his surprise, the chemicals did just that. In fact, the chemicals obeyed all his mental commands.
Mandrill fashioned a "magic wand" from the new compound (which he called "Mentachem") and began experimenting. He found that he could exert complete control over any pure and natural object.
Calling himself the Matter Master, Mandrill quickly proceeded to commit a bizarre series of robberies, until he was apprehended by Hawkman and Hawkgirl. Fortunately for Mandrill, the Hawks did not discover the secret of his wand, and he escaped.
Later, however, during a battle with the Justice League of America, Mandrill was forcibly separated from his wand, and left powerless.
While in prison, Mandrill managed to duplicate an imperfect version of the Mentachem formula. Crafting a smaller wand, he was able to summon the original from the JLA trophy room. He escaped from prison, but Hawkman and Hawkgirl quickly recaptured him.
Months later, Matter Master was recruited by arch-criminal Lex Luthor, when the latter briefly took command of the Secret Society of Super-Villains. This time, Mandrill was defeated by Hawkwoman and Captain Comet.
Though Mandrill has never been very successful as a criminal, he is a hard man to keep in jail, and his current whereabouts are unknown.
