Shiva's Overdrive is Diamond Dust, and deals Ice-elemental damage to all opponents. An electric bolt emerges from his horn which creates a spherical field that levitates the enemy, and another bolt of electricity is fired, which sends them crashing down to the ground.

Ixion's Overdrive is Thor's Hammer, and deals Lightning-elemental damage to all opponents. He jumps into the air and creates two large fireballs which propel the enemies into the air, shoots another fireball, and grabs part of the ground and tosses it at the enemy. Ifrit's Overdrive is Hellfire, and deals Fire-elemental damage to all opponents. Some forms of Valefor (such as Dark Valefor) can use Energy Ray at will without consuming her Overdrive gauge. When fought as an enemy, Valefor uses Energy Blast exclusively as her Overdrive. In Energy Blast, she rises up into the air, flips, and produces a glyph that generates energy beams that rain down upon the enemy. Energy Ray consists of a ray being fired from Valefor's mouth on the ground below the opponents which explodes. Energy Blast, the stronger of the two, is learned by talking to the Besaid Village shopkeeper and then talking to the village dog or its owner later in the game. Both deal non-elemental magic damage to all opponents. Valefor is the only aeon usable by the player to have two Overdrives, Energy Ray and Energy Blast. It is powerful enough to achieve Overkill on all four of Sinspawn Gui's parts, though its body may need to be attacked beforehand. Seymour's Overdrive is Requiem, only used during the one time Seymour fights alongside the party against the second incarnation of Sinspawn Gui during Operation Mi'ihen. This means their power cannot be boosted by Str+% or Mag+% abilities, and they ignore targets' Shell and Protect. None of the playable characters' Overdrives are considered physical or magical, but fall under a third category of "special" damage.

Each character has an Overdrive skillset specific to their personal abilities. Overdrives are powerful attacks available when a character's Overdrive bar is full.
