Dragon Ball Super has not kept any airs about Moro from the start; The baddie is as awful as they come, and he will do just about anything to lore over others. As you can imagine, this kind of attitude was never going to vibe with Goku, but the Saiyan was unable to use Ultra Instinct as need be to beat the baddie. Nowadays, it seems that has all changed, and Dragon Ball has explained how Goku pushed his limits to that point.
For those caught up with the manga, they have an idea of what triggered the Saiyan. The manga's Galactic Patrol Prisoner arc has followed the hero and Vegeta as they joined the force to stop Moro. They were aided greatly by a member named Merus, but it didn't take long for Goku to discover his mentor was an angel. And in order to give Goku a chance to stop Moro, it was Merus who gave his life to nerf the villain.
The latest chapter of Dragon Ball Super finds Goku in shock over the loss, but he does not let his rage overtake him. In the past, that is what would have happened as seen with Krillin's death and others. Goku used anger and rage to fuel his power as any Saiyan would. But this time, Goku channeled his emotional elsewhere which allowed him to tap into Perfected Ultra Instinct.
"Merus may be gone but his will lives on in me," Goku explained.
As it turns out, anger was not the way to prompt Ultra Instinct, but neither was meditation. Goku needed a firm emotional gut punch to help him discover the best way to use his emotions as fuel for Ultra Instinct. The tranquil form required a mandala of sorts to focus upon, and Merus' legacy became that for Goku. Now, he is able to summon the form at will, and that means things are about to end very badly for Moro.
Did you expect Goku to ever perfect the form? Or was this debut a surprise in the end? Share your thoughts with us in the comments section below or hit me up on Twitter @MeganPetersCB.
