Revenge Death Ball
From Dragon Ball Encyclopedia, the ''Dragon Ball'' wiki
The sphere was comprised of the pure negative, dark-blue energy of all the possessed people under Baby's control, making it an evil Spirit Bomb of sorts. Unlike the Spirit Bomb, however, the energy was evidently stored within Baby, and could be replicated (and possibly amplified) at any time after the initial energy was absorbed.
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.

Baby later used the Revenge Death Ball against Super Saiyan 4 Goku. Like the rest of Baby's attacks, it proved useless.
Baby developed two variations of the Revenge Death Ball, both of which were used in his Great Ape form.
- Fire Death Ball - A Revenge Death Ball with a fiery coating, which causes 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.
