My theory is that the brother's original quirk of passing it on also had the feature of making the quirk stronger. So it is the brother's quirk that allows OFA to get stronger every time it is passed on. I am unsure of the nature of the strength quirk that AFO gave his brother, all I know is that it has tons of raw power. However, in my mind it is pretty generic, the brother's quirk really making OFA unique.
