Ultra Instinct is the silver haired transformation Goku first reaches during the Tournament of Power in Dragon Ball Super, which aired from 2015 to 2018. In that form his battle cries and power up screams became a staple of fan edits, because the roar signals speed and strength beyond his previous limits. Clips of the yell were cut into short soundboard files and shared across meme pages and video edits, where it is now used far beyond anime scenes to hype up fights, lifts and dramatic reveals.
