Review Detail of Pedro_Padre in Marvel, Growing in war

I like the slow growth the MC's having/experiencing. He doesn't just out of nowhere go from lifting 300 pounds to suddenly lifting say 90 tonnes. Love his mutation👍👍 Question though? If he hurts himself to develop harder skin as a way of adapting while growing, then does his mutation work in a similar but smaller/lesser way to that of Darwin's or something along those lines of adapting/evolving or not?
