Deku always dreamt of becoming a powerful hero, and after gaining One for All, he finally has a chance of realizing this dream. However, whether he will succeed his mentor, All Might, is still questionable.
He still has his quirk to develop. Will he follow the conventional route of developing it like All Might or will he form his own?
1. Can Deku transform like All Might?
All Might was initially thin, as shown in the manga. After receiving One for All, his body was trained, and it became big enough to hold all of the power. His muscles were built up and made ready to retain 100% of One for All and, therefore, resulting in his buff muscular form.
Deku has just gained One for All and is in the beginning stages of developing it and therefore cannot transform yet.
All Might himself does not transform but trains his body to hold that much power. Deku won’t magically transform and gain a muscular form. He will have to build up and train his muscles and body step by step to hold One for All’s power.
I. Will Deku have a muscle form?
One For All is a cumulation of power. It is not the quirk of being muscular. That is just how it presented itself with All Might. Whereas with Deku, it presents as a sort of energy which wraps itself around his arms and legs and empowers them.
Gran Torino explained that All Might had a body naturally suitable for One For All, which is why All Might’s training was different from Deku’s.
The power presents itself differently, and Deku has already started developing his own fighting style, such as full crawling. Therefore he won’t necessarily have a muscle form as there isn’t a need to transform or have a build similar to All Might.
2. Why can’t Deku transform?
Deku has just gained One for All and is in the beginning stages of developing it. Because of this, he cannot transform yet. Another major reason is that…
…All Might himself does not really transform but trains his body to hold that much power. Hence, Deku won’t really magically transform and gain a muscular form. He will have to build up and train his muscles and body slowly to hold that power.
3. Will Deku be able to transform later?
Since All Might’s transformation was a result of training, Deku will probably have a muscle form if he trains his body. While there is a need for Deku to build up a body suitable to carry and bring out one hundred percent of One for All, there is no need for it to be as defined as All Might’s muscle form.
The reason for this is that All Might built up his body in accordance with his fighting style, which mainly focused on outbursts of strength. Deku, however, is building up his own fighting style and will need a body suitable to it.
