With the seemingly unstoppable Madara getting double-crossed by Black Zetsu and being morphed into Kaguya, things aren't looking good for Team 7 right now.
But, is anyone else getting flashbacks from Dragon Ball: A ridiculously powerful villain gets morphed into an even more powerful one and has to be taken down by the combined might of two rivals, with a little assistance from allegedly "useless" characters?
Super Buu's transformation into Kid Buu and defeat by Goku and Vegeta, with some help from Hercule/Mr. Satan and Dende?
Of course, Majin Buu, the original form, later becomes an ally and Kid Buu later reincarnated into Uub, who becomes a valuable ally and student of Goku.
Maybe Kishimoto's setting up for a Naruto Part III? It's no secret he drew inspiration from the Dragon Ball Series, but maybe I'm digging too deep into it.
