 * During the Super 17 Saga, Goku is unable to kill Frieza and Cell because they are already dead. However, it had previously been established in the Kid Buu Saga of Dragon Ball Z that deceased characters are still susceptible to a second death, wherein they virtually cease to exist. In addition, deceased villains in Other World are not shown with halos in GT, despite being crowned with them during Dragon Ball Z.
