I mean he said hes lightning nature...I have seen him use Katon,Fuuton,Raiton,Doton and Suiton.How is he able to do those if he dont have other chakra natures??IF he is copying the hand seals then why cant others do the same , copy the hand seals and do those jutsus too.This question has been bugging me for like months now and i never came to an answer...
