Gohan didn't stand a chance against Jiren in the Tournament of Power, but Gohan Beast is another story. Gohan Beast seems to be the only one who can defeat Cell MAX, another character who Jiren would likely struggle against.
Can an upgraded Gohan beat up Jiren? Basically impossible to judge, since the movie used a combination of new characters and characters with no real scale against Jiren. By feats, Jiren is definitely still winning.
Especially after receiving Super Saiyan Blue during Dragon Ball Super's Future Trunks arc, Vegito could undoubtedly beat Jiren with ease. A Fused individual's power is greater than the sum of their parts, and Vegito would also theoretically be able to access Ultra Instinct.
Gohan's newfound abilities would not amount to anything if he were to face Lord Beerus in battle. The difference in their overall strength is too huge to cover.
So at the very least, we can draw the conclusion that Gohan Beast is stronger than Super Saiyan Blue Gogeta and somewhere closer to Ultra Instinct and Ultra Ego. It will be interesting to see Gohan sparring against Goku and Vegeta, giving us an idea of his true power level.
1 Gohan Beast, Dragon Ball: Super Hero
Gohan's strongest power transformation is Gohan Beast, an evolved form of Gohan's Potential Unleashed state which originated from the awakenings he has experienced since childhood.
I can't wait to see goban and piccolo haters and downplayers reactionss in a few months when it's actually confirmed in a manga panel that Beast Gohan is above UI Goku and UE Vegeta and Piccolo is equal to them. Akira also stated that beast Gohan, if anything, was just below super saiyan blue.
Gohan always had the most potential out of all the Z-Fighters, but his lack of training and commitment always hindered his growth, while Goku instead keeps getting better. According to Piccolo, however, Gohan can still surpass his father.
I would have to say Broly has the most free access to his potential, Gohan could reach higher levels due to his ability to match anyone through emotional anger: if he was a fighter like Goku he would be up there or even higher.
Even if he is able to get back to Teen Gohan form, the bar for power has been raised incredibly high with the introduction of God Ki. Barring a massive powerup for Gohan in the upcoming Dragon Ball Super: Super Hero movie, the former hero of Earth will never beat Broly.
Can't Defeat: Whis. In Dragon Ball Super, Jiren is said to be a mortal who is stronger than a God of Destruction. Because of this, he is rumored to be able to beat his own God of Destruction, Belmod, and possibly Beerus. But that wouldn't make him strong enough to defeat Whis.
So Jiren would win in terms of pure strength, the guy knocked out Goku, and Buu wins in looking pink…
His title cannot be discussed after we saw him display such strength and might during the Tournament of Power. Jiren is the only mortal being to be above a God of destruction, meaning it is almost impossible for the Hakai to affect him.
Gohan Beast is Gohan's most powerful new form. Unlike the more straightforward Super Saiyan God forms, this one is based on Gohan's more animalistic transformations that he had as a child.
Beast Gohan is far stronger than Goku in his Mastered Ultra Instinct (MUI) form.
goku ssj3 is stronger than ultimate gohan. you say goku could not handle fat buu? goku clearly stated that he could have beat fat buu before, but didn't just because he wanted to give gohan and the kids a shot.
Accordingly, Gohan's subsequent Super Saiyan transformations are bolstered in strength and stronger than usual, putting him above Super Saiyan 3 power during Buu's invasion. After dedicated training his Ultimate form puts him on par with Super Saiyan Blue, which is quite impressive.
There is a reason not Even heroes will ever show beerus losing or even struggling. Even TOEI knows beerus is still supposed to be stronger than any mortal we've seen so far. Beast Gohan may be the strongest mortal in the multiverse we've seen so far but Even he is probably nowhere near beerus.
Post HTC training with Goku during the Cell arc: Gohan came out even stronger than Goku and Vegeta in his Mastered SSJ state. During the battle against Perfect Cell: When Gohan attained the SSJ2 transformation, he obviously surpassed all the Z fighters which include's Vegeta.
“Gohan is actually stronger than anyone… or so it's said… In order to motivate Gohan, it takes his revered teacher, Piccolo rather than his father Goku.” Not Broly, Not Goku or Vegeta, Akira Toriyama confirms that Gohan is the strongest fighter alive!
Both are powerful warriors with a strong sense of justice and a desire to protect their loved ones. As the series progresses, however, it becomes clear that Goten may be more than just a mirror of his father - he may be the true successor to Goku's power and abilities.
Vegeta is undoubtedly stronger than Gohan; his Super Saiyan Blue transformation already gives him the edge, and while Gohan allowed his power to drop as a result of neglecting his training, Vegeta has continued to work hard each and every day.
However, if we compare the two of them in their most powerful forms, Goku has no chance of emerging victorious against Rune King Thor. No matter how powerful his Ultra Instinct could become when he is enraged, this version of Thor has proven to be several times stronger than Goku.
