This special variant of Rasengan is created by infusing the Rasengan with the deadly acidic elemental kekkei genkai and in turn, creating a corrosive attack that can erode away even Wood Release-based attacks.
This attack is further enhanced through the usage of Senjutsu, allowing the user of the technique to throw the attack in the form of an acidic projectile. The user can even augment the size of the attack, keep in mind that these bigger variants cannot be rapidly created and thrown in this state.
