Appearances in games
The Death Bullet appears in many video games as part of Third Form Frieza's Crazy Finger Beam technique. Frieza uses a similar attack in Dragon Ball Z: Idainaru Son Goku Densetsu. The single Crazy Finger Beam blast used by Frieza in his third form was named Death Bullet in Dragon Ball Z: Burst Limit. In Dragon Ball Z: Battle of Z, in addition regular Death Bullets, Frieza is also able to use a stronger variant named Full Power Death Bullet.
In Dragon Ball Xenoverse 2, if the Future Warrior (Xenoverse 2) is a member of Frieza's Race, they can fire Death Bullets as their basic uncharged Ki Blast when they are using the Turn Golden Awoken Skill transformation. The Future Warrior (regardless of race) can also use Death Bullets as part of the Crazy Finger Shot Super Skill.
