Did Fat Boo power up after the battle against Vegeta?

[Let's Go Fearless!]

Was Boo's power up really that extreme? From Ssjin2 tier to nearly Ssjin3 tier?

 

[Captain Cadaver]

I'd say no. He was only suggested to have powered up within the confines of the battle, hence why Vegeta felt the need to go to such extremes and his admittance of having no chance against Boo.

 

[Pyro]

After fighting Vegeta? I don't think so. The only time could be when he's splitting, and that was a different sort of smoke than his "angry smoke."

 

[Lord Beerus]

No. Not in my opinion.

 

[GokhanDBZfan]

Probably yes.
That's what Goku was reffering to with his ''ki like a lie'' comment after all.

Define "ki like a lie".
