fleetway goku and vegeta are the only survivors left from earth every one else was turned into a zombot goku and vegeta can only go ssj to keep the metal virus from infecting them and fleetway is fully corrupted but can control himself from acting like a normal zombot and can keep his normal personality unfortunately to do this it takes a lot of power and inevitably as soon as they are 100% drained they will turn into zombots they can defend against the virus for as long as idw sonic can do it
