Fictional character biography
Dr. Geoffrey Crawford was a professor at Desert State University who took undergraduate Bruce Banner under his wing to mentor him. Years later, Banner went to see his teacher and aid him in finding a cure for the Hulk. At this time, Crawford is paraplegic, but nevertheless able to create a machine that could filter out the gamma radiation from Bruce's body. He saw this as a way to regain his walking ability. By obtaining some samples of the Hulk's DNA, he knew it would allow him to use these recuperative powers on himself. First, Crawford reconfigured his own DNA so that it can match with Banner's. This turned him into a stronger beast similar to the Hulk: the monster called Ravage.
Ravage is more powerful than the Hulk and slightly larger. The key element which makes Ravage such a dangerous enemy is that he still has Dr. Crawford's mind and lust for power. Just after his first transformation, Ravage attacks Hulk, but he soon reverts to Crawford at sunrise, much like Banner initially transformed into the Hulk during nightfall and reverted to Banner at sunrise. Crawford turns Banner over to General Ross for fear of being stopped from becoming Ravage again.
Crawford adjusted his machine so that it will change him into Ravage permanently. He then attacks the university as Ravage and terrorizes those who had pitied him as Crawford. Ravage is only stopped when the Hulk formed an unlikely alliance with General Ross that allows his army to trap the villain in a state of suspended animation.
