Unless he learned how to use fire or water or earth or lightning by himself which is more impossible for Naruto.
I wouldn't be surprised if his secret move was something similiar to destructo disk. Or that one move Sailor Moon uses where she turns her tiara into a destructo disk.
....A really flat version of rasengan?
it's obvious (well for me it is) that this mountain-cutting jutsu must be his rasenshuriken we know, but perfected.
anyone who has an idea that fits better?
The Sharingan's TRUE power...
UCHIHA MADARA'S POWER!!!
An invincible immortal.
THAT is who Uchiha Madara is.
He summons a 1000 crows with Itachi's head on them that shoot laser beams out their mouths when then squack
remember naruto said that the shurken rasengan isnt complete yet so i think its the complete version of the shuriken rasengan
A common mistake that people make when trying to design something completely foolproof is to underestimate the ingenuity of complete fools.
What if it was a chakra sword and just throws it with control of chakra and stuff, that would pwn
my theory is hes transforming his kage to shurikens then throwing it end result flying rasenshuriken
