Disclaimer: This article is just an assumption based on some theories out there as we are yet to witness this fight (however it could very well happen in the future). We shall be using information majorly from the manga to support our assumption, and some facts from anime too has been considered.
Since the mad powerhouse Jiren made an appearance in the tournament of power, Dragon Ball fans have been crazy about him. His power levels are a frequent topic of discussion on online forums with fans pitching him against numerous other characters. One such much sought power level comparison is between Jiren and Beerus. Before concluding who is more powerful let’s start by finding out some facts about Beerus and Jiren.
Beerus is the God of Destruction and his strengths were on display when he fought Goku on Earth. However, it was revealed in Dragon Ball Super that Beerus did not use his full power while fighting SSJ God Goku. In the Dragon Ball Super manga, even before the tournament of power began, there was a battle of gods where all gods of destruction fought against each other. This takes place after Goku requests Zeno to organize an opening ceremony of sorts for the tournament of power. In this battle (which was omitted in the anime completely) Beerus fights with all gods using ultra instinct and that fight shows that he is stronger than majority of god of destruction.
The extent of Beerus’s power is further made clear when Whis states clearly that Goku and Vegeta’s God-like powers were like a tree when compared to Beerus’ which is as huge as his castle on his planet (sorry saiyan fans but that seems like a pretty huge gap). Beerus has trained with angel Whis and he has achieved ULTRA INSTINCT.
Lots of fans don’t know that Beerus has mastered UI to a great extent (even if not completely). In the Battle of Gods tournament Beerus is seen using his ultra instinct and he is easily able to overpower most of his opponents.
However, the question here is not if Beerus is the strongest God of Destruction. Of all the information that we presented nothing compares his powers directly to that of Jiren. Infact Jiren’s power level is yet unknown, so this is where we start making the assumptions.
Jiren is very proud of his strength. He even refuses to accept the help of his team even when he is pressurized by opponents. Just like Goku, jiren feels uncomfortable knowing that an opponent is not using their full power against him and he will not use any more strength than necessary and let his opponents attack him first instead of going berserk on opponents. This is one of the major reasons why we won’t know if Jiren has gone full power in any of the fights that we witnessed.
Jiren was said to be the strongest mortal in all the universes and even stronger than the next candidate for god of destruction, Topo. It’s said that Jiren is even stronger than Belmod( God of Destruction of universe 11).
During the tournament of power, Whis confirms that the rumor about the existence of a mortal who is stronger than the gods in a certain universe is true. Here, Whis was refering to Jiren being stronger than Belmond.
Is Jiren Stronger Than Beerus?
Let’s now come to the main point, is jiren stronger than beerus? So the answer is no (Hold on, we’ll tell you why). Since there is no way to compare their powers directly as they haven’t faced off yet, we will be using their battles with Goku as a reference.
Beerus is way stronger than we think. Beerus can nullify the attacks of his opponents with ease, like we saw him nullifying Goku’s Kamehameha with one hand while fighting against him on earth. Jiren probably cannot do this.
Jiren was pushed to his limits (apparently) while he was fighting Goku’s Ultra Instinct mode. Beerus at full power, using ultra instinct would be more powerful than Goku’s level from when he was facing off with Jiren. And then there is Hakai. Frieza did not survive Hakai, It is the unparalleled energy of destruction. It’s literally Shift Delete.
Fans would argue that Beerus doesn’t have MUI since he hasn’t perfected it, according to Whis!” But then consider this, Goku in his Ultra instinct form (which was close to mastered, not completely mastered) was able to knock out a Limit Broken Jiren. Gods have way more durability, stamina than mortals and their Ultra instinct forms are stronger than mortals. So, MUI Beerus > MUI Goku who beated Limit Broken Jiren. So, Beerus can easily do that too.
Now another set of people also claim that Beerus was afraid of Goku’s MUI and Jiren’s Limit Broken form. Well, Beerus was not afraid, instead he was simply surprised how the mortal bodies of Goku and Jiren were able to bear such a divine form.
Akira Toriyama, creator of the DBS, himself said that if Goku is a 6, Beerus is a 10 and Whis is a 15. So, if Goku could beat Jiren with an overall power level of 6, think what Beerus can do with him with a 10.
It will be a very close and intense battle indeed, but we feel Beerus will win this one. Though there are also some of us who’d like to believe that Jiren will get his ass handed down to him by Beerus in a serious fight.
