Revenge Death Ball Final
From Dragon Ball Encyclopedia, the ''Dragon Ball'' wiki
The Revenge Death Ball Final (リベンジ デス ボール ファイナル, Ribenji Desu Bōru Fainaru) is the most powerful version of the Revenge Death Ball and used by Baby in his Great Ape form. It is charged and maintained the same way, but with much more power, possessing enough power to destroy a planet – a capability not seen in the original.
Great Ape Baby used the attack in his battle against Super Saiyan 4 Goku. The Saiyan absorbed the massive energy, however, and launched it into a powerful 10x Kamehameha at Baby, severely damaging the Tuffle parasite.
