we all know goku got hit by an axe at the very begining of dbz and did not fill it whiles naruto can be killed by a shuryken and goku withstands a shot gun to the head when goku faces krillin he has grown way stronger than before so has krillin meaning krillin cannot be affected by axe’s and shurykins ...
and when krillin fights goku they cannot be seen by human eyes we ..so if we put a krillin near the end of dragonball he would be more than a match for naruto
krillin has superstrenth+speed+agility+indurance+reflexes
