Nappa got hurt from the attacks of the Z fighter when he was caught by surprise.reecehoward wrote:Only when they let their power down, not when they are actually fighting.

With how UIO Goku moves he could logically catch somebody off guard, and when it’s completed he would definitely be able to seize that opportunity.
Vegeta has his tail cut off by Yajirobe due to a surprise attack, and his power would have been 100s of times higher than anything Yajirobe could muster.
Final form Freeza got kicked in the back of the head by Piccolo and was really pissed after. We know he wouldn’t have powered down at that stage, and for arguments sake let’s say even if he did, he would’ve still been many times stronger than a Piccolo that needed to take energy from Gohan and Krillin who were also a lot below their best.
In super we have #17 hit Jiren in the back with a ki blast in the Super anime, and Jiren didn’t drop his power.
Those are instances of characters not letting their power down, as Nappa, Vegeta and Freeza didn’t know how to suppress their ki below their initial levels.
Trunks also does knock Rose Black back in the manga when he’s trying to destroy the time machine, and I’m sure he does something in the anime too. The last one isn’t the best example, but the Jiren vs Goku fight shows you that if the foe knows where the attacks are coming from they aren’t really gonna be budged. Also the gap between Jiren and Goku would be much closer than the gap between SSJ2 Trunks and Rose Black.
So yeah I believe UI could capitalise on hitting Jiren from behind, and actually catching him a little off guard if he attacks him from a position that Jiren hasn’t seen coming/anticipated. If he can’t truly do much damage he could at least knock him out of bounds.
Anyway, isn’t their a moment in Super where Whis states that Saiyans are a race that get stronger through transformations? If that’s correct I guess Goku having a special form for UI may be a Saiyan exclusive thing, and because it gives him a new form his strength also increases alongside it.
Just a thought.
Edit: I actually forgot the most important off guard moment for Goku.
When he attacks Toppo in the DBS manga he’s defeated in one blow because he let his guard down, even though he was at full power.
