Quakemaster

Quakemaster is Robert Coleman, a former architect who turned to villainy after his reputation was destroyed by a natural disaster. He wields a custom jackhammer that emits powerful energy waves capable of demolishing buildings and breaking bones. Without any superhuman powers, he relies on his engineering skills and his destructive tool to challenge Gotham City. Quakemaster has appeared in various DC Comics stories since 1977, often clashing with Batman and other heroes.
