The Negative Karma Ball (ネガティブ カルマ ボール, Negatibu Karuma Bōru) is Omega Shenron's most powerful attack. Omega Shenron pushes his chest forward, channeling pure negative energy through the dark-blue Dragon Balls on his chest. Small red streams of energy fly out and start to form a crimson energy sphere with a pink center as it expands many times its original size. Omega Shenron condenses the sphere to about the size of his body and launches it at the opponent, inflicting a huge amount of damage.
Omega Shenron first used this attack in an attempt to destroy Super Saiyan 4 Gogeta and Earth. Gogeta teleported in front of the Negative Karma Ball, however, and channeled some of his positive energy into it as he kicked it up into space. This changed the Negative Karma Ball into a positive energy sphere (with a blue color) that soon created a nuke-like explosion upon leaving the Earth's atmosphere.
Omega Shenron later used it against the weary Son Goku and Vegeta, which nearly killed the former. Omega Shenron used the Negative Karma Ball on Goku again while he was holding the Universal Spirit Bomb, but to no avail.
Negative Karma Ball appeared in Dragon Ball Z: Budokai 3, Infinite World, and the Budokai Tenkaichi video game series. In these video games, it is named Minus Energy Power Ball and is Omega Shenron's Ultimate Blast.
