Supreme Ultimate Rasengan

Naruto merges his Rasengan with Minato's to create a Rasengan swirling-like drill that drills through the opponent causing massive damage. The Supreme Ultimate Rasengan like the Tornado Rasengan has several streams of chakra spiraling around the centre, but it has far more streams completely covering the users' bodies. These streams are capable of deflecting attacks. The sphere itself appears unstable, with the shape fluctuating wildly unlike the solid sphere shape of other Rasengan techniques.
