G.I.-Joe R.H.I.N.O. Driver
Filename: Warden, John
Primary Military Specialty: Transportation
Secondary Military Specialty: Infantry
Birthplace: Sioux Falls, South Dakota
Canonball is the driver/pilot of the G.I.-Joe team's R.H.I.N.O (Rapid Heli Nuetralizing Offense) vehicle. It is rumored he got his codename because he was once a human canonball, but he will not confirm or deny it. What is known is he used to test drive trucks before enlisting, litering the road with the remains of vehicles he tested to their limits and beyond. This allows him to know exactly how far and how hard he can push the R.H.I.N.O. and will drive it to that limit. He piolts the helicopter with the same fearless enthusiasm as he drives with.
