How did Jiren become so powerful in DBS? It's because of when his family was murdered right in front of him and he was powerless to stop it, and then when his friends and his teacher were murdered in front of him again. He was too weak to stop everyone he cared about from being butchered.
During the Tournament of Power, it is revealed Jiren's motivation to get stronger is a result of losing his parents and losing to the person who killed his parents. As a result, he vowed to never lose again and being pushed into a corner would cause him to be traumatized like before.
1 Goku Isn't Stronger Than Jiren
Moreover, Goku hasn't trained with Ultra Instinct enough and that means his body will keep breaking down after he uses that technique, even if just for a few minutes. Jiren, on the other hand, has much more control over his skills and he'll only get stronger.
Jiren is considered to be the strongest among the participating competitors, as his power is said to rival or even surpass those of the universes' deities; his goal is to be given access to the Super Dragon Balls by winning the tournament.
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.
But without Ultra Instinct, Jiren still has the advantage over Goku. In order to defeat Jiren, Goku had to team up with both Frieza and Android 17. On his own, the only hope Goku has of defeating Jiren is by fully mastering Ultra Instinct, and being able to activate it at will.
No.. Jiren is not stronger than Beerus. However, it is speculated by Whis to be so as Whis said the word “perhaps”. Also, Whis only said that Jiren is in the level of God of Destruction (that one is confirmed), being stronger than a God of Destruction on the other hand, is only speculated by Whis.
Super Full Power (超フルパワー, Chō Furu Pawā) is a powerful state Jiren is capable of taking on after breaking his limits. Rather than being a state beyond it, some media refers to this state as just being Jiren's Full Power.
Jiren's wish was to resurrect his fallen mentor!
Unable to receive recognition from Gicchin as his successor before he passed away, Jiren wanted to resurrect him to show him the incredible power he had gained.
1 Jiren Doesn't Have Ultra Instinct
Once a person has gained Ultra Instinct, it means that he/she can attack, defend, and resist based purely on instinct. They do not have to think about an attack before attempting it. Basically, it gives the user the strength of doing things in battle without thinking about them.
Gicchin appears to have been a very noble person, as he took an orphaned Jiren in and trained him along with many others so that they could fight for the sake of justice. He even sacrificed himself to save his remaining students from being killed.
If Jiren just eliminated everyone in the first episode of the Tournament, the arc would have failed. Just like Fused Zamasu didn't kill everyone as soon as he opened his eyes and instead wasted time toying with them.
Broly, like all Saiyans, is powered by sheer rage, and should he go into a fight angry, he may catch Jiren off-guard. While engaging in a normal bout, however, Jiren has a definitive edge.
What makes Jiren so strong in Dragon Ball Super? He's able to defeat a God of destruction and is even stronger than Beerus.
As one of Dragon Ball's most powerful, Jiren's strength surpasses even that of a God of Destruction. This possibly makes him the strongest known mortal in the multiverse. Needless to say, defeating Jiren is quite a difficult task.
His remaining friends gave up hope on avenging their lost ones and moved on with their lives. From that point onward, Jiren was alone and trained so he could become stronger, as he no longer believed in trust, only in strength.
While he had lost everything, Jiren does not become evil and instead becomes an overall selfless and heroic, but distant and cold. Possessing a powerful sense of justice, Jiren devotes everything in justice and never acts for selfish reasons.
At Full Power, Jiren's glare can stop three energy blasts at the same time and blow everyone away. On M-2, Pan uses the technique to destroy an alarm. Perfect Cell uses an invisible eye blast in Hell to knock the Ogres away before he and Frieza fight Goku.
He doesn't have a physical weakness but a psychological one. This is even stated in the DBS manga itself. I'm surprised nobody has referenced this. Jiren's strength is based on sheer determination and resolve to rely on himself alone and his own strength.
Super Saiyan 3 Goku at full power has a battle power of 24,000,000,000, 2 billion above Kid Buu's level.
Even an Ultra Instinct Goku couldn't defeat Jiren, a level of transformation that is presumably on par with Ultra Ego. Ultra Instinct even offers more defensive viability and success than Ultra Ego. This just highlights Ultra Ego Vegeta's inability to defeat Jiren right now.
Goku's first experience with Mastered Ultra Instinct (MUI) pushed Jiren to his limits. By practising Ultra Ego and eventually reaching the equivocal level, Vegeta will likely defeat Jiren single-handedly.
Whis is one of the strongest beings in existence, and interestingly enough, only his father and the Omni King are confirmed to be stronger than him.
It's because ultra instinct is a power that no saiyan can get but Goku already got it that's why they were shocked to see Goku using ultra instinct ultra instinct is a form that can only be obtained by meditation and calm mind that even god of destruction can't do.
