Midoriya Multiverse Madness

Ultra Instinct

"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?"
