Android 21 creates a massive ball of energy above her head and directs it at the enemy. When the sphere hits its target it creates either a giant cross-shaped explosion, or a spiraling fiery explosion.

Absolute Release Ball was introduced in Dragon Ball FighterZ as an attack by Android 21 used to destroy Android 16 during the Super Warrior Arc and Enemy Warrior Arc It later appeared in Super Dragon Ball Heroes as Android 21's super attack under a different color scheme.
In Dragon Ball Z: Dokkan Battle, the human form of Android 21 called Android #21 (Normal) uses the technique as her Super Attack. Her good personality is in control when she uses it based upon her quote, which is ironic given that her evil personality uses the technique to murder Android 16 in the Super Warrior and Enemy Warrior Arcs.
