I have no clue why I forgot that, especially since it's the best fight Gohan had as an adult, just because of what a ruthless MF Gohan was.
Shame that didn't carry over to the TOP.
Gohan doesn't quite have the power to back up that level of arrogance, but I see where you're coming from. It would be cool if he was a bit like the Kaku from One Piece.
And your post kind of remains me why I really don't like Jiren that much. Unlike most here, I actually don't mind his lack of personality or him being stoic. He remains me of Lucci.
My problem with Jiren is the same problem I nave with Toppo. This guy threw his team to the wolves at least twice, with the most standout example being how he let Hit and Goku beat the crap out of Dypso and ring out one of his teammates when they were already hurting members after the Kale and Cali fiasco. I mean, Jiren could have rung out both Goku and Hit without trying which would have weakened U6 and U7 and kept their numbers up since the tournament will be determine on who has the most members remaining if there's anyone left in the ring. And he did it again in this episode since despite his overwhelming power, he rung out only one person, failed to break the other universe's' spirits, and while he badly injured Goku, he's still in the ring and will count as part of U7's score if they make it to the end. Jiren should also know that U7 still have several members who can threatened Dypso and Toppo since he should have sensed Vegeta in Blue and Frieza's brief time as Golden Frieza, yet decides not to take them out even if they are no personal challenged to him, but would be trouble for his remaining teammates.
Overall, despite being part of a super hero team, Jiren isn't a team player and he has a 'all about me' personality which fits a common Dragon Ball villain, but is out of place for what he's supposed to be. Hit, a freaking assassin that Jiren looked down on, did more for his team than Jiren did for his, and he worked with these people all the time with Toppo supposedly being his 'swore friend'. Hell, Frieza is a better team player than Jiren.
