Robert Coleman is an architect in
Gotham City whose reputation is damaged when an apartment complex he designed fails to withstand a
hurricane. Feeling that he has been wrongly branded, Coleman creates the alias of the Quakemaster and uses his super-charged
jackhammer to create earthquakes in Gotham City. His scheme backfires and only his buildings are damaged in the quakes. Quakemaster is defeated and captured by
Batman. Quakemaster is later released and recruited by the
Secret Society of Super Villains to be part of the team working with
Silver Ghost to kill the
Freedom Fighters. This story was scheduled to appear in
The Secret Society of Super-Villains #16-17, but the title was canceled before it could be published. It eventually appeared in issue #2 of
Cancelled Comic Cavalcade, a limited series produced by DC Comics. Quakemaster takes to hanging out with other villains who have apparently fallen on hard times. This group includes
Black Mass,
Sonar,
Blackrock, and
Cavalier. The villains gather at a New York bar to play games of
poker. In one such game, the villains lose most of their weapons and devices to civilian Wally Tortelloni. When the villains gang up to track Tortelloni down and retake their devices, they are apprehended by members of the
Justice League International. In
Infinite Crisis, Quakemaster rejoins the Secret Society of Super Villains. ==Powers and abilities==
