Re: Rikudo Sennin's True Powers
He was the main creator of chakra and certain power by means of jutsu (gen, tai. nin)
Example; Seal, Eye technique, etc; not every jutsu.
Then each clan created their own jutsu.
Uzumaki said to be the creator of many types of sealing method.
Uchiha and another clan (cross married) = Hyuga.
Who knows when one clan married another clan and so on, yet another new jutsu.
Example; Minato created his famous FTG, by means of sealing technique.
Madara was famous to "use" ninja for his objective.
So now he "Use" SO6P (control Ten Tails) for his own purpose.
