Well did it fire a huge blast. if it did then u mastererd it but just to make sure....(forms a shadow clone and it forms a katon rasengan) we will smash our two rasengans against each other using clones becuz if mine is stronger than that means u didnt completely master it and ur clone will be obliterated with double the power of a normal one but if they are equal they will clash and cause a huge inferno to explode over, id say, a mile-radius.
So lets test it out.
Madara clone: OK lets do this! (charges at zanji)
KATON RASENGAN!!!!
(THE TWO CLASH AND A BRITE LIGHT ERRUPTs AND A LOUD NOISE COMES. It is impossible to see at the moment)
Madara: no i think we will be safe here(his eyes closed)
(the explosion ends up ending a couple of feet away from madara and his hair blows wildly)
Madara: (Opens his eyes) Looks like it was an equa match. Congratulations u have mastered the Katon Rasengan. I will make a thread to celebrate. oh and how do u say "dragon" in japanese?
Wait a minute, look at this zanji.
Suiryuudan no Jutsu - Water Dragon Projectile Technique
Karyuu Endan - Fire Dragon Flame Projectile
Gouryuuka no Jutsu - Great Dragon Fire Technique
Doryuudan - Earth Dragon Projectile
I think its
Ryuu=Dragon
So the name is Rasenryuu!!!!
