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 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, though it can destroy a planet upon contact, if he chooses to use the full power of the blast.
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 Goku, but is only able to form part of it before it is cancelled due to the Golden Great Ape attacking Baby Vegeta. Baby Vegeta later uses the attack against Goku, which, like the rest of Baby's attacks then, proves useless toward the Super Saiyan 4.
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.
