Thomson was born and raised in San Jose, California, growing up in the east side of the city. Being half-European-American and half-Mexican, Thomson faced discrimination and got into fights often. In middle school, he was involved in a brawl in which the principal was punched while trying to break up the incident, resulting in Thomson being placed in a juvenile hall. Afterwards, Thomson went to live with his father in Idaho where he went to high school and competed in wrestling. Thomson continued wrestling at junior college powerhouse, North Idaho Community College, and also trained with the wrestling team at Stanford University before deciding school was not for him. His college wrestling record was 40-3. In 2000, Thomson was involved in an alcohol-fueled brawl while on a lake cruise in Idaho. In the melee Thomson choked one man so badly that he required CPR and as a result, Thomson was charged with felony aggravated assault, serving six months of a three-year sentence before being released for good behavior.
