So I have brainstormed on this for hours. What if All For One and Kyudai Garaki decided not to take One For All anymore. As in what they decided to create a Quirk similar or closely mimic OFA. I think if they were to create their own version of OFA, they would need a bunch of quirks to combine in a person or a Nomu. Creating their own version of OFA will be either deciding that they don't need it anymore or that they have their own version of it.
Since it's known that Kyudai Garaki or Daruma Ujiko can create a copy version of someone's quirk. For AFO and Kyudai to wanting to steal OFA from Izuku and not realizing that they can create their own version of it. It's like they AFO wanted to combined OFA with the AFO quirk. Or that AFO wanted it for himself. But if they were to create their own version of it they will need these quirks that I'm thinking of.
For enhancing a person's Power and Speed
- Muscle Augmentation
- Kinetic Booster (8 or 9 copies)
- Strength Enhancer (8 or 9 copies)
- Impact Recoil (For reinforced damage or for counter attacks)
- Shock Absorption (Absorb damage from harming itself)
- Springlike Limbs
- Hypertrophy
- Power
Since All Might and Izuku Midoriya can use wind pressure attacks
If someone was to all these quirks they will have to use it in a combination like AFO did during his battle with All Might. For enhanced strength or power they'll need Muscle Augmentation, eight or nine Kinetic Booster, eight or nine Strength Enhancer, Hypertrophy , Power, and Impact Recoil. And to absorb any backlash Shock Absorption will be the perfect if needed to absorb or cancel out any damage on itself. Springlike Limbs could be possibly be used for an attack it maybe helpful.
And to jump high or for enhanced speed they'll need Muscle Augmentation, eight or nine Kinetic Booster, eight or nine Strength Enhancer, and Springlike limbs. With these combination they'll be able to move very fast, possibly faster than the eye can see. Or they'll just move so fast that the naked eye couldn't see it. And like how All Might could jump very far and high a quirk combination of this could be helpful.
Since All Might has used Texas Smash and Detroit Smash for mid or long range attacks and Detroit Smash was used in close range. and New Hampshire Smash was to redirect someone in the air. And Izuku has used Delaware Smash or Delaware Smash Air Force and St. Louis Smash Air Force for long range attacks. For someone to have their own version of OFA. They'll have to do it like how All For One did his enhanced Air Cannon. But this counter version of OFA will be stronger that AFO's Enhanced Air Cannon because it has more Strength Enhancers and Kinetic Boosters.
All these quirks combined together will be perfected way to create their own version of OFA. I possibly think that if all these quirks could evolve into one quirk. But I don't know if AFO will try to make his own version of OFA.
