Did Goku use his FP Base against Ubb?

I don't remember his expressions.

 

[Evil Vegeta]

He was testing Oob, so I doubt it.

 

[Yoshi]

At any rate, I don't think Oob used his full potential against Goku, either.

 

[Captain Cadaver]

He seemed to be taking it seriously during the panel in which they clashed. The only reason for having Goku not using his full power here is if you're trying to include DBS within the canon.
