Omni-Factor Unleash, full name Omni-Factor Unleash: All For One Goal, is an Ultimate Move performed by All For One using the All For One Quirk.
Description#
All For One summons every single Quirk in his possession, mutating his body drastically into a form that provides him overwhelming offensive power. He explains that this Ultimate Move is the result of him exacting his ultimate control over his Quirks, and not from giving in to basic emotions.[1] Though this move is designed for massive, sweeping attacks, All For One has displayed the capability to generate tendrils and other appendages from his mutated forms, allowing for more precise attacks, or for use of his original Quirk.[2][3]
All For One first used Omni-Factor Unleash against Dynamight during the Final War, attempting to obliterate everything in his path and reach Tomura Shigaraki at the same time, in order to transfer his consciousness into him and take over his body. As a result, his body took the form of a monstrous mass of flesh covered with numerous Vestiges of the stolen Quirks' original users; large Accelerator Rings, Dark Balls, and black lightning also surrounded him.[4]
However in the midst of this attack, All For One suffered a rebellion as the Vestiges exploited his enraged state to rally against him, leaving him unable to muster the attack's full strength once his initial charge was halted by Dynamight. All For One found himself unable to mix his Quirks together properly, leaving him vulnerable as Dynamight destroyed Omni-Factor Unleash with a Howitzer Impact.[2]
After his Vestige possessed Tomura's body once more, All For One used Omni-Factor Unleash again during the final battle against all the Heroes. This time, it took the form of endlessly sprouting black tentacles which he used for offense, accompanied by large Spearlike Bones-like projectiles, and devastating lasers shot from organic cannons, while he blocked any significant attacks against his main body with a barrier Quirk. He was able to battle the entire assembled force of Heroes simultaneously using this form, with each of his attacks requiring dozens of Heroes to counter.[5][1] However, the transfer of One For All into Tomura's body left it so damaged that using Omni-Factor Unleash caused his body to degrade, and it only took a single blow for his control over it to crumble.[3]
Weaknesses#
Omni-Factor Unleash puts tremendous stress on the user's body, to the point where it is not viable to use safely with an ordinary body. When it was first used, All Might was able to tell just by looking at it that the damage All For One was inflicting on himself would accelerate Rewind to the point of reverting him to an infant.[4] When using it a second time, even with Tomura's enhanced body, the stress of using the move, in addition to previously sustained damage, resulted in All For One beginning to break down, cracks appearing on his body and fluid leaking from his hands, and the move ultimately collapsed after only a single blow to the main body.[1][3]
Because of the transformation's massive size, All For One becomes a massive target and any attacks that can exploit this are particularly effective. Dynamight was able to land an entire barrage of Explosions with ease,[2] and Thirteen was able to interrupt one of his attacks using her Black Hole Quirk, the suction dragging in his entire body at once.[5]
Omni-Factor Unleash inherits the weaknesses of the numerous different Quirks used in it. For example, Impure Beam retained its light-based qualities, allowing one of Omni-Factor Unleash's beams to be diverted by Invisible Girl using her Invisibility Quirk.[1]

Trivia#
- "Omni-" is a combining form derived from the Latin word "omnis", meaning "All". This fits how All For One uses all of his Quirks in order to bring forth this attack.
- Hawks is one of the many Vestiges that can be seen around All For One's mutated body when he uses Omni-Factor Unleash, and shortly afterwards one of them who rebels from within.
- Omni-Factor Unleash's grounded state during All For One's battle with Dynamight is shown in the second version of THE REVO, although the full might of the attack isn't shown.
- The second variant of the attack can also be seen at the climax of the opening, albeit with "All For One's" form obscured by the light of One For All.
