Life Force

Life Forceis the Quirk used by Kyudai Garaki and All For One.

Description
Life Force allows the user to double their life span, causing him to age at a slower rate, making him look much younger than he really is. That's why Kyudai Garaki look like he's only in his sixties when he really is at least 120 years old. If the Quirk is canceled, the user rapidly ages into a much more decrepit shape.

At some point, Kyudai duplicated his own Quirk and presented the original to All For One as an offering while he kept the duplicate to himself.

Weaknesses
This Quirk comes at the cost of sacrificing physical mobility. However, All For One appears to have managed to circumvent this weakness through the use of multiple other Quirks.
