this is probably gonna be said no to pretty quick, but, worth a shot

[SITHISIT]

so

Goku Black has all of Goku's abilities, potential, and power...

and UI goku is high 3-A

Shouldn't Goku Black have a potentially High 3-A rating somewhere for "Stated to have the same amount of potential as Goku does".

And notice the word

p

o

t

e

n

t

a

It means that it has not happened per story, however it can easily happen and the character has the potential to do so, and/or came close to it.

So

tl;dr give Goku Black

3-A, potentially High 3-A (Stated to posess all of Goku's potential and abilities)

 

[Dragonmasterxyz]

No.

 

[The_real_cal_howard]

No

 

[ProfessorKukui4Life]

Yeah definitely not agreeing with this.

 

[Kaltias]

No

 

[Dragonmasterxyz]

Also, just so you know, we aren't joking.

 

[Schnee_One]

Goku is High 3A because of ultra instinct.

Black doesn't have Ultra instinct.

This is obvious
