I thought that natural lightning was superior but if it was how did Kakashi cut it with his Chidori/raikiri? If kakashi did this, lets say he uses a huge raikiri, will he be able to cut through Kirin?
If kakashi could do the rasengan without any training (that I know about) by coping with sharingan (probably) can other sharingan users do the same? :dunno:
