We've all seen where the omnitrix took control of Ben's severed hand in an episode of UAF. Lets say, due to plot convenience, a guy managed to break the omnitrix's plethora of failsafes (and manages to kill Ben) except for one.. And that would be the omnitrix taking over Ben's corpse as its new body to complete its inevitable mission as an Ark of life.
