Goku in Dragon Ball can transform into powerful forms like Ultra Instinct and Super Saiyan 4. He has over 10 different transformations, each adding unique abilities. People debate which form, Super Saiyan 4 or Ultra Instinct, is more powerful.
Getting Super Saiyan 4 in Dragon Ball GT is complicated. First, something must make Goku go Super Saiyan, like seeing his student Uub get hurt. Then, he transforms into Golden Great Ape. Finally, he changes from the wild ape form to Super Saiyan 4.
The controversy around Super Saiyan 4 is that it’s only in Dragon Ball GT, not the main series. So, it’s not officially part of the main Dragon Ball story.
Ultra Instinct is Better than Super Saiyan 4
Super Saiyan 4 is powerful because it combines the strength of the Golden Great Ape with a Saiyan’s control. In the manga, the Great Ape form gave Saiyans various abilities, and GT shows that the Golden Great Ape form enhances these even more.
The challenge with Great Ape forms is losing control, but Super Saiyan 4 solves this problem, allowing Goku to keep control. On the other hand, Ultra Instinct, first seen in Dragon Ball Super, is more of a mental state than a physical transformation.
Goku learned it from Whis through training, but it’s hard to master because it requires controlling emotions. Goku can’t use it perfectly at will. For example, in the fight against Jiren, it activated when he was losing rather than when he wanted to.
Goku’s True Ultra Instinct is his Strongest Form
Ultra Instinct is better for defense than offense. When Goku’s in this state, it’s like time slows down a lot. This lets him see attacks super slowly and dodge them easily. People using Ultra Instinct don’t have to decide to defend or attack; their body naturally reacts to threats or chances, moving effortlessly.
The problem is, unless the user masters it completely, it’s very tiring and only lasts a short time. In the manga, Goku mastered an improved state, True Ultra Instinct, which lets him keep it longer.
He even uses his emotions with it, unlike before. This power helped him beat Gas, the strongest fighter in the universe at that time. True Ultra Instinct is stronger than GT’s Super Saiyan 4, making it Goku’s strongest form in Dragon Ball.
