He was the son of an Air Force colonel, who believed Smallville was being overrun with meteor-infected people. After the second meteor shower, his father became a metahuman as well; Gabriel claimed he begged him to kill him. The inside of Gabriel's house was covered in newspaper and magazine articles and clippings detailing the effects of the meteor rocks on the town. Gabriel was the computer wizard at the Smallville Torch at Smallville High and was accepted into MIT.
Season FiveHowever, instead of leaving the town, he followed through with his father's plan. When he had read all he needed to know about missile launching, he used his father's plan to execute the launch of a missile that would head straight for Smallville to destroy all life in the city. He overtook the control booth for a missile launching station by killing the guards on duty. He tried to warn Chloe Sullivan to save her, but she enlisted Clark's help to stop Gabriel. Clark accosted Gabriel, who shot him in the abdomen. He kidnapped Chloe and left Clark to die in the street. (Clark was later revived by his Kryptonian father Jor-El.)
Gabriel forced Chloe to witness his execution of the launch by tying her to a chair. However, she got loose and she knocked him out in an attempt to abort the launch. But Gabriel revived shortly and he and Chloe fought until Chloe managed to defeat Gabriel when she accidentally shot him with a gun and killed him.
