Dash Kamehameha

Dash Kamehameha is a variation of the God Kamehameha used by Super Saiyan Blue Goku to kill Frieza in the climax of the Golden Frieza Saga.

Overview
After Frieza destroys the Earth using his Earth Breaker, Goku realizes that he should have killed Frieza when he had the chance and is reminded by Whis that he can thanks to Whis' Temporal Do-Over, which rewinds time back 3 minutes before Frieza destroys the Earth. Just as Frieza is about to initiate his Earth Breaker, Super Saiyan Blue Goku charges towards Frieza shouting the tyrant's name which distracts Frieza from finishing his attack. Goku continues flying towards Frieza, then stops and fires a God Kamehameha at Frieza which kills the tyrant.

Appearances in Games
This technique was named in Dragon Ball Z: Extreme Butōdenand appears as SSGSS Goku's Final Ultimate Combo. Since it is a Final Ultimate Combo, it can only be performed while SSGSS Goku is in the Awakened state (achieved at low health), with his Spirit Gauge charged to 200%, and the combo to use it must be performed in the air. When performed SSGSS Goku will charge up his energy then charge towards the opponent before firing a powerful God Kamehameha.[1]
