"Hey guys. I know I said the next universe would be a sad one, but we're having difficulties getting that one. SO I'll have to show you this one earlier than I planned." The voice told everyone.

"Oh, thank goodness." Ashido said relieved.

"This universe is called 'Ultra Instinct.' Midoriya was in a fight with a villain, who used an energy attack, mixed with Midoriya's quirk, that made him disappear, and appear dead. Don't worry, he's alive. The villain he fought is more powerful than All Might thanks to experimentation. Midoriya couldn't even land a hit on him, and barely escaped some of his attacks. Let's get this started."

Opens up in Musutafu. A giant crater is in the city with many looking at the hole in shock and surprise. There's a villain in red and black, with white gloves and boots, overlooking the crater.

"What's that crater?" Kirishima asked.

"That's where Midoriya was when he was hit." The voice explains.

Uraraka puts her hands over her mouth in shock. "D-Deku?"

"It seems like he wasn't truly worthy after all. Good work Jiren." Another villain in a similar outfit coming behind Jiren. Toppo. He was of a more chunky build with muscle, and had a large white mustache. Another came. Dyspo. He was slimmer, and had a rabbit like appearance. 

"Where is he? I can't see him." Iida asks. "Dammit. He's always bounced back before, he can do it again." Uraraka says unsure this time.

"With their Symbol of Peace gone, the heroes should be cowering before us." Shigaraki says from a rooftop. But to his surprise, the heroes just walked up to the crater preparing for a fight. "It seems they think they can take Grey. I somehow pity them." Dabi says with a disappointed look.

"Even if a symbol of peace is gone, or even dead, heroes will always rise against evil. No matter how strong they are." Midoriya says standing up.

All Might smiles at yet another great speech by his successor.

"Is this really the end for you nerd? For all of us?" Bakugou questions clenching his fist. He clenches his teeth in anger. "Deku. DEKU!" Bakugou yells. The everything around them starts shaking.

"It's finally happened. Bakugou's yelling caused an earthquake." Kaminari laughs. He is then hit by an explosion. "Shut. It."

"What's with these tremors?" Toppo asks. Jiren raises his head in interest. "The city-no. The entire east side of the country is shaking." Aizawa says. "What's causing it?" Iida asks.

Kaminari smiles. "If you ask me, there's only one good answer." Monoma speaks up. "Yes, I agree. Time for the real fun to begin." All Might smiles. "Toshinori, is there something you wish to say?" All Might just responds. "He's coming."

A giant beam of light emerges from the crater, raising the rubble around it. In the light is someone standing to their feet. Everyone just stares in awe at the spectacle. Once the light fades and the dust clears, Midoriya is standing there. The first layer of the top of his costume is destroyed, and he has a heavenly blue aura surrounding him. When he turns to everyone, he has a look for battle, and his eyes are silver.

"WOAH! That's looks so awesome!" Kirishima exclaims. "What is this? Is it his quirk? I thought it was just a power enhancer." Iida asks.

"You'll see soon enough." The voice answers the nerdy, attitude-less Sonic.

Uraraka smiles and has tears of joy in her eyes. "Deku!" Toppo and Dyspo arrive behind Jiren to see the green haired hero. "Deku endures. What has he done?"

"I don't know how to explain this, but based on what I'm seeing, he didn't survive on dumb luck." Todoroki says. "Something's different about him, that's for sure." Kaminari says. "He's just so calm, it's giving me the creeps." Kirishima says. "Let's just kick back and watch. I didn't think someone with this quirk could end up like this." Gran Torino says confusing the two young heroes.

Midoriya looks at Jiren and is ready for battle. He lifts his foot into the air, and next he's next to Jiren with a kick that was avoided.

"Whoa. That was so fast. Even for him." Yaoyorozu says. "I'm not that fast." Midoriya says rubbing his neck. "Stop being so humble Deku. You may be faster than Iida." She says giving one of her best smiles. Which is a trick because all her smiles are her best smiles. He blushes at the compliment.

Everyone looks surprised at the new speed.

(AN: Trust me. Play this. End when told.)

Midoriya flips back, then Jiren throws a punch. Midoriya, as if he has a new sense, evades it and throws a punch, and Jiren counters with another punch. This sends Midoriya back into the hole. Jiren goes in for an attack, but Midoriya rushes past him, grazing Jiren's cheek.

"How did he do that?!" Bakugou yells. 

"Watch. Talk less." All Might instructs him.

Everyone is shocked at the new powers Midoriya is showing. It's as if he has a new quirk, or he's possessed. "Midoriya may have only grazed Jiren, but it did connect. Considering he couldn't touch this guy at 100% is amazing." "I can't sense his attacks at all like this. The same goes for his dodges." Iida says. "What the hell is going on? I'm watching this with my own eyes, but I still can't believe what he's doing is actually possible. Deku, what have you become?" Bakugou talks to himself.

Jiren and Dyspo slide down the side of the crater. "You don't know when to surrender, Deku. You've already lost this fight!" Toppo yells. They launch themselves at him, Toppo going for a punch, Dyspo going for a kick.

Midoriya crosses his arms and grabs both of their attacks, and tosses him away.

Toppo slides up against the crater again. "Doom Flash!" He sends a bunch of energy attacks from his fingers and sends them at Midoriya. He just turns around and walks towards Jiren not caring about the attacks. He knocks one away.

"That was very impressive." Aizawa says. "THAT WAS SO INSANE!" Present Mic yells.

Jiren turns fully to the green hero and raises his hand at Toppo saying that he'll handle it. "You wish to face Deku alone." He says complying with his allies' instructions. Midoriya continues merely walking towards Jiren, then flies over to him. Jiren closes eyes and sends a barrage of punches. Midoriya evades every one of them with swift movements. He breaks Jiren's chain of attacks, and starts his own barrage of punches and kicks. Jiren knocks way each strike, but his feet start going into the ground. The take their battle into the air and send blow after blow, hit after hit, block after block, trying to get a hit on the other.

"Holy...wow." Is all Sero can say.

"So. Who do you think has the upper hand now?" Jiro asks. "It's too early to say. With that said, there used to be a massive power gap between them. But Midoriya is nearly close to him. And that's not all." Tokoyami answers her question.

"Extraordinary. As strong as he's become, Midoriya's not done improving." Todoroki says as he observes the battle in awe. "Everytime Jiren fends him off, Midoriya responds with an even faster, sharper, and harder strike." He continues.

"What kind of power is this? I've never seen, or even heard of a quirk like this. Ribbit?" Asui ponders at this power.

"Impossible. I didn't think anyone could push Jiren this far." Kurogiri says. "What the-?! How can this be happening?!" Shigaraki says while scratching his neck intensely.

Gran Torino speaks up. "Yes! That's it! I didn't think that it would become this powerful!" Kaminari looks at the old man. "You know what's happening to him?" "Yes! And it's the mind of thing we need to win this!" All Might just stares at the two fighting.

(End the music)

He then speaks up. "Ultra Instinct." Everyone is astonished at the name. "It must be some quirk if it can do all this." Kirishima says looking back at the battlefield. "It is. It was the quirk of the second holder of OFA. Though it was just called 'Instinct.' It was a simple quirk that could avoid any attack. The user's reflexes are enhanced to where their muscles move on their own without thinking. Like a state of pure focus and calmness. It slightly increased the user's speed and strength, but it seems the power being passed down constantly must have made it much more powerful. He made this quirk plus ultra. Ultra Instinct." He whispered to All Might so the other two can't hear them. "How did young Midoriya awaken the quirk now of all times?" All might asks. "I may have a theory. When that giant energy attack collided with that smash of his, it created a pocket black hole of energy. And it awakened yet another dormant quirk locked inside him. He broke his limits.

"That's a hell of an explanation?" Todoroki speaks up.

"Tell me about it." The voice says.

Gran Torino. "Yes. He's now in uncharted territory. It remains to be seen what will happen if he tries to sustain this power without training it." He says.

Midoriya and Jiren remain suspended in the air and Midoriya comes closer to be face to face with the villain.

The send punch after punch, creating shockwaves and raises the air pressure sending wind past everyone.

"This is so epic! Take him down!" Bakugou yells surprising everyone.

Midoriya's eyes then flash their normal color, then back to silver. He let's out a roar that sounds like he has two voices. His normal voice mixed with a deep roar.

He lands a kick on Jiren, then uses a smash to send him to the ground. He lands on the side of a very tall building. He then sends himself at Jiren with his left fist in front of him. The then lets out another roar and sends another punch at Jiren.

Smoke covered the area. No one saw who was down.

"Who won? Did Deku win?" Uraraka asks worried about her boyfriend.

Jiren is covered by a red aura. "Deku. You are a truly fascinating creature. However..." The dust clears to show Midoriya with his eyes back to normal and the glow surrounding him gone, and his attack was caught by Jiren. "You're passion is expected. You have nothing more to offer." He then uses blast to send Midoriya away.

"Deku/Midoriya!" The class yells.

"That power seemed only temporary. Come Kurogiri. Let's go home. We've seen all that we need to." Shigaraki says to the warp villain, and they disappear.

Jiren turns to his comrades. "Come. There's nothing left for us here." He turns his head back to Midoriya. "If we battle again, use that technique. It intrigues me." He then turns back to the other two, and they disappear.

"And that's the end of that universe. What's you guys think?" The voice asks.

"It was awesome! Midoriya was so manly is this!" Kirishima yells with passion. "He was so strong, and so fast. I've never seen anyone fight like that."Kaminari says. "His abilities were very impressive. But what was Gran Torino talking about when he said 'One For All?'" Todoroki asks.

Midoriya, All Might, and Bakugou sweat.

"That's a story for another time, I'm afraid. I have to show you depressing shit." The voice says.

"Fuck!" Ashido yells.
