Goku’s Ultra Instinct form is one of the most exciting stuff right now in the Tournament of Power. WIth even the Gods choking after seeing him transform like that, Goku’s position as one of the most powerful mortals is reinstated. Of course, Jiren is still another story, but Goku’s newest transformation is something that didn’t happen before, Even Whis and the Grand Priest was surprised.
Is this a Super Saiyan form? I wouldn’t think so. Super Saiyan forms are different in a sense that they can be achieved and strengthen by doing the right training and reaching the right requirements. It is also unlike Kaioken in which you can use it on the base form as well as on top of other forms like Super Saiyan Blue. It needs a spirit bomb the only Goku could make.
The Ultra Instinct form is also frighteningly calm compared to all of Goku’s transformation discoveries. If the Super Saiyan is the most violent, this one is so quiet that even Goku did not utter a single scream during transformation. This transformation might also be a one-time big-time transformation in a sense that after its appearance, we’ll never be able to see it again.
If there’s a reason why it would appear again, the reason would be because the form is still incomplete. Goku can make the power of Ultra Instinct stronger than ever before. Remember the promotional poster that the official DBS Twitter account posted months before the Tournament of Power? That legendary Goku’s bruised back?
The absence of the red aura which can be seen in the promotional photo caught my fancy. The fact that only half of Goku’s clothing was left in the photo, compared to his clothing right now, it can mean that we might see a stronger and more complete version of that form later on.
And not only that, Goku made a spirit bomb out of the participant’s standard Ki, hence the blue color. But what if someone who possesses a God-ki (like Vegeta) mixed in some of their energy in Goku’s spirit bomb? This might be the where the red aura would appear.
In one way, the red aura could also mean Goku’s rage. Rage can empower a Saiyan, as seen in many circumstances before, like Gohan and Trunks. If Goku can hold ultra-instinct longer and will also be able to lean on to his rage, Jiren might consider himself very unfortunate.
