How is Asura using Rasengan?


In Naruto anime episode 468, Asura is shown to be using a Rasengan based jutsu
against Indra. If I'm not wrong, the Fourth Hokage Minato invented Rasengan
several years later. Am I missing something here?




It may not have been rasengan, but just gathering chakra and rotating it for
more power. My defense of this would be Indra's using a similar jutsu to
chidori in this filler arc. Both jutsus are similar to the modern day jutsus
we know, but not quite the same
