Is there an opponent which weakened Goku who needs all the time to regenerate his stamina can't defeat?
He defeated Kefla SSJ2 who was stronger by him in that moment in term of power just by UI dodging ability and battle experience.
He now will get the robots by releasing his full power but still in his weakened state.
At this point till the end of tournament Goku won't have time to regenerate stamina fully to go on par with Jiren.
How they want to make it possible, especially since Jiren used all this time to meditate to regain his power?
