In Dragon Ball Super Chapter 73, Goku confronts Granolah, and Cerealian discovers Ultra Instinct’s weakness.
Thanks to his Ultra Instinct training, Goku has reached new heights of strength not seen in the Dragon Ball franchise. However, as the Saiyan’s battle against Moro demonstrated, Goku’s grasp of Infinity Instinct is far from perfect. And in Dragon Ball Super Chapter 73, Goku’s problems with Infinity Instinct are perfected proving that Goku’s ability to capture action is far from perfect.
At the start of Dragon Ball Super Chapter 73, Goku and Granolah face off against each other, preceded by a combination of Super Saiyan Blue and Ultra Instinct. During the pause in their fight, Granolah noted that his eye – which allows him to find other people’s weaknesses – found no weaknesses to exploit.
After Granolah notes that not being able to transform is not without problems, Goku replies, “No, infinite instinct has no weakness. If anything is missing, it must be my learning. […] I’m not quite used to using Ultra Instinct as a Super Saiyan. So we are still vulnerable. Later, the Saiyans were forced to retreat after a sneak blast from Granolah.
When the two next fought, Goku used his Perfected Instinct form – and Goku proved to be completely overpowered. But just when it seemed like Goku would finally defeat Granolah, Vegeta discovered that the last Cerealian was actually fighting his countrymen with a clone. Before Vegeta could warn Goku of what was happening, Granolah teleported to Goku and hit him at a critical point, taking Goku out of the fight for the time being. “Your accuracy degrades over time in gray hair form,” boasted Granolah. “I can finally find a loophole.”
While the Perfected Ultra Instinct is a powerful form, Goku’s fight with Granolah proves its limited capabilities. By using a number of tricks, Granolah was able to gain an advantage and defeat the Saiyan in a form usually reserved for the gods. However, this problem does not occur with Ultra Instinct itself. Instead, the problem is that Goku still hasn’t fully mastered form. So while Ultra Instinct makes Goku incredibly powerful, his own inexperience with the form proves responsible in combat.
