"I'm gonna finish this right now."
The Imperfect Instinct Kamehameha is effectively a Kamehameha wave performed with much more energy output and force than even a God Kamehameha. Much like its original version, it can be manipulated to the user's advantage, such as sliding along an incoming blast to close the gap or quickly converting the energy into a defensive barrier.
Usage and Power
Ultra Instinct -Sign- Goku used this attack to defeat Kefla during the Tournament of Power after she attempted to defeat him with her Ray Blast and Gigantic Burst, claiming he was unable to dodge the blast in midair. By flipping in the air and sliding the Kamehameha energy sphere on top of the Gigantic Burst, Goku was able to close the distance between them and unleash the Imperfect Instinct Kamehameha point-blank, sending her flying off the stage and forcefully shattering the Potara, eliminating her (and by effect, Caulifla and Kale together).
Later during the Tournament, Goku uses Imperfect Instinct Kamehameha in his battle against Jiren, although it is negated by a concentrated Power Impact, enabling Jiren to blast Goku away, but he managed to use the energy of his Kamehameha as an energy shield to reduce the strength of Jiren's blast.
