User blog:GAMEONBOI/How strong is deku

(spoilers)

So in the latest anime episode they revealed a new villain known as overhaul. (Manga spoilers from here) Deku fights this villain and uses something called 100% full cowl which was the real 100% of one for all power. In the new film we see prime all mights power which is all mights real 100% however this is far more powerful than 100% full cowl appears to be. Could anyone explain why dekus 100% seems weaker than all mights?
