An energy ball is an ability used offensively in the Yu-Gi-Oh! ZEXAL anime. The user creates a medium-sized to large-sized energy sphere with a color determined by the wielder. It was first used in the series by Fortuno during his number hunt. Hart Tenjo was able to create an energy ball around him and make it grow larger. Vetrix was later capable of doing so with the power he stole from Hart. Later in the series, the Barian Emperor Mizar produced energy balls to use as weapons, though they did not cause permanent harm. He also generated a red energy ball upon arriving on Earth from the Barian World, a variation that was later used by Vector. After Ranking Up with Barian power, Number 96 opened portals and launch extremely powerful energy balls much like the Barians, as seen when he attacked the Astral World and the Barian World.
