The sphere is comprised of the pure negative, dark-blue energy of all the possessed people under Baby's control, making it an evil Spirit Bomb, of some sort. Unlike the Spirit Bomb, however, the energy is evidently stored within Baby, and can be replicated (and possibly amplified) at any time after the initial energy is absorbed.
The attack is strong enough to shake the very fabric of dimensions, as seen when its aftershock made Kibito Kai accidentally drop Goku while in the teleportation dimension. After the first use against Goku on Earth, Baby Vegeta later uses the attack against Uub, although Mr. Buu quickly moves in and inhales it, saving Uub. Later, Baby Vegeta attempts to use another one against Golden Great Ape Goku, but is only able to form part of it before it is cancelled due to Goku attacking Baby Vegeta. Baby Vegeta later uses the attack against Super Saiyan 4 Goku, which, like the rest of Baby's attacks then, proves useless.
The Revenge Death Ball appears to be highly volatile as it will explode upon contact with anything, even the ground, making it unable to penetrate the surface of the Earth, like Frieza's Death Ball is able to. Although it is Baby's strongest attack, because it cannot penetrate the Earth, the Revenge Death Ball is incapable of global destruction, unlike the Super Galick Gun.
Appearances in games
Revenge Death Ball is Super Baby Vegeta 2's Ultimate Blast in Dragon Ball GT: Transformation, the Budokai Tenkaichi series, Dragon Ball Z: Infinite World, and Dragon Ball Heroes. In Dragon Ball Heroes, the sphere is surrounded by a purple, white, and gray outer layer, and it is also used by the player's avatar, such as the Saiyan and Android Elites.
Baby has developed two variations of the Revenge Death Ball, both of which are used in his Golden Great Ape form:
- Flaming Death Ball – A Revenge Death Ball with a fiery coating, causing a more powerful flaming explosion upon impact.
- Revenge Death Ball Final – A larger and much more powerful version of the Revenge Death Ball, and Baby's absolute strongest variation of the original Revenge Death Ball.
- The Revenge Death Ball could be considered the exact opposite of a Spirit Bomb. But it is also similar because Baby contained much more hate and a thirst for revenge than man other Dragon Ball Z antagonists, and also, Baby is the only being seen being able to create the Revenge Death Ball, just as Goku is the only one seen being able to create the Spirit Bomb. Most likely, the Revenge Death Ball requires a being completely dark of heart, just as the Spirit bomb requires someone with a pure heart.
