Furio was one of the thugs that worked for Danger Danger. The only reason he had his position was due to his relationship to his uncle, Il Pazzo. Il Pazzo had promised Furio's dying father that he would take care of him, but Furio made Il Pazzo so mad sometimes that he regretted making that promise.
While Danger Danger was raiding a Czechoslovakian military base and toxic waste dump (which was a front for a secret rocket launch facility), Furio killed the Czechoslovakian radio announcer and took over the radio. He then proceeded to taunt the Czech soldiers, expressed his dislike for the cold weather and attempted to rally the Danger Danger thugs in a vain attempt to stop John Jack from stealing the second Czech rocket to the Moon.
