Mastered Ultra Instinct 4



Mastered Ultra Instinct 4 is the fifth form of Super Saiyan a Saiyan can take, directly following Super Saiyan 4. This form is obtained by mastering Super Saiyan 4 and pushing it to its limit, similar to Super Saiyan 3. It can also be obtained when panicing about someone you care about about to die but you're too far away. When this happens, a wormhole appears and you teleport to them, creating a protective field and pulling them and everyone else around you back through the wormhole to where you came from. Like Super Saiyan 4, Super Saiyan 5 does not use alot of energy quickly, so it can be easily held. It's power is about as strong as the dark FIVE.

Physical Appearance
A Mastered Ultra Instinct 4's hair grows to the length of a Super Saiyan 3's hair, except white. The fur on their chest also turns white as well. Other than this and a white aura, it looks like a white haired Super Saiyan 3 Super Saiyan 4. Their muscles are also really large, too.

Goku
The original user of the Mastered Ultra Instinct 4. He is the first to use it, the first to master it, and generally the first to obtain new forms of each stage of Super Saiyan. It is safe to say that Goku is the master of the Super Saiyan.
