Goku unlocked Ultra Instinct at the end of the Dragon Ball Superanime while fighting Jiren during the Tournament of Power, but the end of the series made it clear he can't use the transformation whenever he wants. Dragon Ball Super: Broly doubles down on this when Goku briefly taps into Mastered Ultra Instinct in his battle with Broly, only to almost instantly power back down to Super Saiyan Blue. Dragon Ball Super 2 will dedicate a lot of time to Goku mastering Ultra Instinct, but the form will no longer be Goku-exclusive.
