Bomber DX (デラックスボンバー) is an energy sphere attack frequently used by Nappa in his battle with the Z Fighters.
Nappa holds his hand out and charges a fierce pulsating white energy sphere in his hand. When it is ready, he reels back and tosses a large, pure white energy sphere at the opponent that creates an enormous explosion on contact.
Nappa uses this attack to destroy Yetti on Arlia before the battle on Earth, completely vaporizing the Arlian. On Earth, Nappa uses the attack against Krillin in revenge for having his face scratched by Krillin's Destructo Disc. Krillin becomes injured by the attack, but Nappa is interrupted from launching a second one by Piccolo's Destructive Wind. Nappa uses the Bomber DX again in an attempt to murder Gohan, but ends up killing Piccolo instead when he jumps in the way of the blast. Powered up, Nappa uses it one last time against Goku, who nullifies the attack with only a scream.
