John's Arm: Armageddon (2008)

Unkempt security guard John's right arm was transformed into a costumed super-limb after being stuck in a vending machine (stocked with irradiated soda). With villains from around the globe hitting town for their annual convention, can John's Arm (and his low-rent super-team, the Superior Friends) keep the bad guys at bay and save Earth from total annihilation?
