Impure Beam

Impure Beam is a Quirk used by All For One, who stole it from an unknown user.

Description
Impure Beam allows the user to unleash a large and destructive beam of light. This Quirk is one of the strongest in All For One's arsenal, capable of inflicting massive, widespread damage in a single shot.

The Quirk's devastating abilities have been shown to combat Fumikage Tokoyami and Dark Shadow's Light of Baldur, as well as taking out Gigantomachia in one-shot, and destroying 66% of the Armored All Might's shields. He uses this attack in conjunction with other haphazard Quirks in his third encounter with All Might.

Weaknesses
The downside of this Quirk's power is that when it is pushed to its maximum output, with the aid of additional Quirks, it causes the user's arm and/or whole body to be blown apart. However, All For One is able to circumvent this damaging weakness thanks to his body's regeneration courtesy of the Rewind drug.
