Did Uub retain his previous life power level??

[Devauzamaki]

I never understood it. If you consider Gt canon then baby vegeta said hes stronger than gohan,goten,and trunks combined.

Without Gt it ended with goku training him to be the next saviour of the world.

 

[Mahesvara]

GT isn't canon.

 

[HENI]

like 1% of it

 

[jiraiya the toad sage]

the way i'd put is that he kept the potential to be that strong but not the power itself

 

[Ōkami]

Well GT isn't canon so nothing to worry about.

Probably most, Chronologically he fought on par with base goku who was powered up after fighting Beerus (The God Power became a part of Gokus power).
