I’ve been thinking, and I’ve come to the conclusion that Jiren is still the strongest mortal and here’s why:
- Jiren not only dominated Goku for the majority of their fights, but everyone else on the arena
- Goku had to train with Whis to gain his power boost(s), whereas Jiren gained his massive strength all by himself
- Even after unleashing Mastered Ultra Instinct, the “Ultimate” Battle Form, Goku still struggled against Jiren
- Towards the end of the tournament Jiren was completely gassed out (despite powering up to maximum, that was pretty much all pure adrenaline), which was the only reason Goku gained the upper hand
- Even when Jiren was running on an empty tank, he STILL put up a brutal fight
- Lastly, now that Jiren is aware that beings such as Goku & Vegeta exist, he will continue to train & become even stronger, pushing the gap even further between him & every other mortal. Broly might be on par or even stronger than Jiren, but next time we see him (and we will), he will be leagues beyond Broly
