A Lesson Quantum Fizzics : The Equilibrium
He will tap into his 9th chakra and become one with Existence. You see, when Fizz uses his E he enters a state called Quantum SuperFizzicion essentially fading into the fabric of the universe. Normally, Fizz cannot stay in this state as his mind is too young and unstable because he can't handle the pressure of observing the mortal plane from a window of a higher reality. However, if Fizz learns to accept his role as the eye of Nagakaboros he stay on his pole for the rest of eternity never to torment another soul again.
