Destroyer

Vegeta found himself in the company of his family when he suddenly detected two immensely potent energy signatures, surpassing any he had ever encountered in his battles. It became evident that Goku and Beerus were engaged in a fierce confrontation. Goku, in his True Ultra Instinct state, appeared battered with his attire torn and bloodied, while Beerus showed no signs of relenting, relishing the encounter despite being similarly injured. Their battle unfolded amidst the cosmos, with Beerus relentlessly pursuing Goku, thwarting any attempt at escape.

Beerus: You can't run away from me, saiyan! I'm impressed how you found your own version of ultra instinct, it's even stronger than that silver haired perfect version you have shown before but you will never scale up to a god.

Goku: Just you wait lord beerus. I'm not done, this fight isn't over until I say it is. Check this out. KAIO-KEN!!!!!

Goku engaged the Kaioken multiplier in conjunction with his True Ultra Instinct form, progressively amplifying it to a factor of 20. Employing unparalleled velocity, Goku executed a surprise gut punch on Beerus, rendering his movements imperceptible even to Beerus. Subsequently, Goku propelled Beerus skyward with an uppercut, unleashing an unrelenting barrage of consecutive strikes. He culminated his assault by harnessing the formidable Ultra Kaioken True Kamehameha, achieving a flawless impact on Beerus, resulting in a detonation. However, Goku discerned an anomalous presence emanating from the trajectory of his attack. Despite Vegeta's belated warning, Goku found himself confronted by Beerus in his ultimate state, harnessing the amalgamated energy of Ultra Instinct and his full power. This marked the culmination of Goku's defeat as Beerus incapacitated him with a single blow, precipitating his descent. Beerus, lamenting the brevity of the encounter, harbored a sense of disappointment, having relished the engagement.

Meanwhile, Goku's consciousness delved into a profound introspective state.

Goku: Why? Why can't I be stronger than beerus?! It doesn't seem possible anymore!

???: Yes it does. Nothing is impossible.

Goku: Huh? Who is that?

???: I am the source of power inside of you that got you to where your level is at now. You can defeat lord beerus, your potential is unlimited. Think of how far you've got, you never would've gotten this far in power enough for lord beerus to show his true power.

Goku: I did get pretty far, but what does that mean? He one shotted me in my strongest form. Even when using my version of ultra instinct it still doesn't mean anything to him, I multiplied kaioken with it as well!

???: Listen son goku, think of how you've got your new ultra instinct. Do the same thing with the angel's technique and power of ultra instinct.

Goku: Do the same thing? Wait. I think I get it! I CAN BEAT HIM!

Goku regained consciousness, arresting his descent, and mustered adequate energy to ascend to his peak potential in the True Ultra Instinct state. However, an extraordinary metamorphosis commenced, altering his being into an entirely distinct entity. Beerus, perceptive to this transformation, observed Goku's altered state, wherein his visage remained akin to that of Ultra Instinct, yet his eyes transitioned from silver to yellow. Leveraging his emotional reservoir in tandem with the Ultra Instinct paradigm, Goku achieved what he termed "True Perfect Instinct," astounding Beerus.

In response, Beerus resumed engagement, albeit taken aback by Goku's evolution. Dispensing with any preamble, Goku unleashed the entirety of his power in an unprecedented display, engaging Beerus at full capacity for the first time. Employing his signature one-inch punch, Goku inflicted notable damage upon Beerus, who, despite his resilience, remained restrained. Subsequently, Goku opted for a decisive maneuver, amalgamating all his strength into a singular assault.

As Beerus conjured a Supernova attack, he simultaneously amassed energy for a colossal Hakaishin Spear, fusing both techniques into a formidable Hakaishin Supernova. Unperturbed, Goku countered by channeling a Kamehameha wave, executing a maneuver reminiscent of his confrontation with Kefla: riding atop the energy sphere, teleporting behind Beerus, and delivering a decisive Kamehameha to his cranium, rupturing the fabric of reality.

Exhausting his energy reservoir, Goku reverted to his base form, leaving Beerus reeling from the aftermath. Despite sustaining significant injuries, Beerus exhibited resilience, electing to extend mercy by summoning Whis to facilitate Goku's recuperation.

Beerus: I'm having second thoughts about this saiyan.

Whis: Oh? And what is that, my lord?

Beerus: He made me show my true power just now, he got so far that he pushed me to this point. I'm wondering how far he can go to truly satisfy me. Whis, make sure you train this saiyan to be my true rival like he was supposed to be the first time I saw him.

Whis: Yes my lord.
