Form and name misconception
It was pretty clear from the beginning already but Vegeta doing the same thing proves this.
This form has nothing to do with Ultra Instinct and it's usage along with it with Goku is purely coincidental. From the start we knew UI was ONLY a technique used for a speed boost and when Goku got his new form it was a power boost caused by 'breaking his shell', the activation of UI was clearly only due to Goku being in an unconscious state and still fighting ergo emulating the technique. Vegeta has now done the same, broken his shell, and it did not grant him UI, he specifically separated this from UI by stating Goku could keep UI and he was going to achieve power on his own.
This form should be referred to as what it is, separate from UI and the product of 'breaking one's shell' and should be treated as the base of Vegeta's new form as well, instead of treating it like it's own thing separate from Goku's use of it.
Vegeta and Goku are using the same base transformation (broken shell or w/e) and Vegeta is using Blue on top of his while Goku is using UI on top of his. —This unsigned comment was made by Koibito888 (talk • contribs) Please sign your posts with ~~~~ next time!
