Extinction Bomb is a device issued to members of the Galactic Patrol capable of wiping out entire species'.
The Extinction Bomb is a Capsule-sized device issued to members of the Galactic Patrol. Jaco once used one to destroy some people and was reprimanded by his superiors, indicating that its use is not taken lightly by the Galactic Patrol due to its ability to wipe out entire species.
In Dragon Ball Xenoverse 2, Jaco mentions the Extinction Bomb during his final training session with the Future Warrior (Xenoverse 2) in School Quest: "Lesson 3". At first he states that he will go all out meaning that he will use Extinction Bombs if he has to, but decides that it might upset people so he decides against using it.
- Though stated to be powerful enough to wipe out all of humanity if used on Earth, it does not seem to be capable of killing extremely powerful beings such as Frieza (if it was capable of killing Frieza, the Galactic Patrol would have certainly used one to destroy the evil tyrant).
