Hospital Raid Team & Trainees vs. Tomura Shigaraki

Hospital Raid Team & U.A. Students vs. Tomura Shigaraki is a battle between a few Pro Heroes who survived the destruction of the Hospital Raid Team and along with multiple U.A. High School students against the the Grand Commander of Paranormal Liberation Front Tomura Shigaraki during the Paranormal Liberation War.

Prologue
The heroes had managed to storm the laboratory under Jaku's hospital and stop Tomura's adaptation process with the All For One when he was at 75%. However, despite being declared dead, Tomura awakens after experiencing a dream-like state where he saw his family and his master. While at Jaku City, Izuku can feel that the vestiges are warning him that something terrible is about to happen and looks at the hospital.

Seeing the lab overflowing by heroes, Tomura unleash a massive wave of Decay that utterly obliterates everything and everyone around him. The heroes are forced to beat a full-scale retreat, but Tomura's Decay expands far more rapidly than before and most of them don't make it out alive. Only a few heroes manage to escape from the hospital before it’s destroyed, taking doctor Garaki with them.

The wave of destruction continues to spread, reaching the Jaku City in the span of seconds. Izuku and Shoto use their Quirks to stop it with no avail. Seeing the devastation from Tomura’s Quirk, Burnin orders everyone to flee, grabbing the civilians in arm’s length they run. She tries reaching out to the Hospital Raid team hoping for a response on the situation, but receives none.

In the wake of the destruction, there's nothing left the area anymore but a giant crater. Tomura approaches to a Quirk Erasing bullets machine, which he had avoided destroying with his attack, but had been damaged during the heroes' raid. Tomura laments that only a few bullets can be useful. Suddenly, he hears a voice in his head and is confused by the intrusion in his thoughts. Ignoring this, he notices that he now has control over his Decay Quirk, and picks up a communication device from the ground and summons Gigantomachia, telling him to bring everyone towards him.

Coming from the sky, he sees Endeavor falling towards him like a raging meteor, determined to stop Tomura from escaping and cause more devastation. Tomura just greets the Number One hero almost casually.

Battle
As he sees Endeavor approaching him ready to attack, Tomura gets distracted when the voice urges him to get the One For All, unconsciously activating the Quirk Search. This distraction makes him unable to avoid Endeavor's scorching Super Move Flashfire Fist - Hell's Curtain. Endeavor unleashes a large number of flames, trapping and engulfing Tomura in a fiery inferno, assuring him that he has no way to escape from.

Even though Tomura is on fire, Endeavor does not intend to allow him to take any step further, and decides to neutralize him as soon as possible with a Jet Burn. Before he releases his attack, Tomura jumps out of the flames in his direction and tries to touch him with his hand, but Endeavor bends backwards to dodge it. The hero is surprised by his speed and especially that he has managed to resist the intense heat of the flames. And then he realizes that Tomura has Super Regeneration that allows him to withstand the burns.

Using his flames to spin in midair, Endeavor grabs Tomura, throwing him violently against the ground without releasing him, and continues to burn him. The Hero radios in and orders all the heroes that can move without touching the ground to create a perimeter around them.One of Tomura's hands emerges from the flames to try to touch him again. Endeavor successfully grabs Tomura's arm before he ahs the chance but then Tomura uses his new Air Cannon Quirk to blows him far away.

Tomura realizes he has inherited all the Quirks his master collected with  Quirk. Before continuing to fight Endeavor, Tomura salvages a couple of Quirk-Erasing bullets from the wrecked machine and pockets them. He also retrieves the amputated hand that he uses as a mask as Endeavor charges back at him.

As he fights the number one hero, Tomura feels that despite all the incredible new powers he has, he doesn’t feels satisfied, as if something of his is still missing. The voice inside him tells him what it is, and Tomura mentions out loud that he must get the One For All. Endeavor, who was close to him when he says that, radios and this information to his sidekick Burnin, Although she doesn't know what that words mean, she replies that help is on his way. She doesn't realize that Deku has overheard her conversation. The second she mentions the words "One For All," Izuku figures out Tomura is after him.

Burnin orders the students and civilians to evacuate with the Heroes as Deku tries calling out to her with no avail. Using the Search Quirk stolen from Ragdoll, Tomura pinpoints Deku’s location, and urged by the desire to get the OFA, he stops fighting and jumps away in his direction. Endeavor pursues him, reporting that Tomura is heading to the evacuation zone for some reason, and gives the proper orders.

As all the others start worrying about Tomura's arrival, Deku is aware that if he remains there, he endangers civilians, heroes and his classmates, so he immediately starts leaping away from them, to lead Tomura to a deserted area. Katsuki Bakugo, who also knows what is happening, decides to follow him. Shoto and Ochaco calling them out, and Izuku claims they have to go to other direction. Then he contacts Endeavor via the private frequency and tells him that Tomura is looking for him.

Endeavor, while pursuing Tomura, is confused by Deku. He promise he will explain later, but now he needs him to tell the direction Tomura is taking, as the dust and smoke is obstructing his vision. Endeavor is about to tell him he doesn't have time for that, when suddenly Tomura suddenly lands on the ground to locate Izuku's position at that moment. Endeavor attacks him with a blast of fire. However, Tomura dodges and changes his direction. Endeavor tells Deku that he is heading southwest, and Deku says he will buy time for evacuation before hanging up. Endeavor immediately informs the rest of the heroes Tomura is heading southwest, and he has a Super Regeneration Quirk.

While in the air, Tomura becomes frustrated with the fact that the heroes are communicating electronically. To get off Endeavor and disrupt communications, he uses Air Cannon Quirk in conjunction with a Radio Waves Quirk, to release a blast that jams all the communicators. After pinpointing Izuku once more, Tomura finally catches up him and Katsuki. He reaches his hand out to Izuku, demanding to hand over One For All, as both students experiences the image their deaths.

All of a sudden, Gran Torino interrupts their brief confrontation by dragging Deku and Katsuki away to safety. He explains that he heard everything over the comms, and that they should not face Tomura because his Decay is now much more powerful. Deku tries to protest but Gran Torino reminds him that there are other Heroes that can still fight, and as powerful as he has become, he can't beat all of them.

Sure enough, as soon as Tomura steps on the ground, Ryukyu attacks him in her dragon form and swipes him with her claws. Tomura catches Ryuku's claw, believing she'd be disintegrated by now, but to his shock, the Decay doesn’t work, and he gets swatted into the air. In turns out that Eraser Head, held by Rock Lock and Manual, is using his Erasure to cancel Tomura's Quirks. Although he does not know why Deku and Katsuki are there, he angrily states to Tomura that he won't allow him to lay a single finger on his students. Tomura sees him and, as a call back of their first battle at U.A., he says he is rather cool.

As more and more heroes appear to face him, Tomura decides to implement a backup plan so, while still in the air, he uses the communicator to command an unknown recipient to kill anyone in sight. Meanwhile, Eraser Head is being helped by Manual and Rock Lock to because his leg was crippled by a Nomu. Manual is using his Quirk to moisturize Eraserhead’s eyes and prevent him from blinking, Shota can use his Erasure for longer on Tomura. This way he can use his Erasure for longer on Tomura.

With Tomura still in the air, Ryukyu calls for Endeavor, who charges towards his sidekick Kido as he forms a loop with his bandages for Endeavor to fly through. He immediately uses his Traject Quirk to change Endeavor's trajectory straight up at Tomura. Upon reaching him, Endeavor unleashes a large blast of fire but Tomura dodges it, though his left arm gets burnt.

Heroes are shocked that Tomura managed pushed himself aside, as his Quirks are supposed to be nullified as Eraser Head claims that at no point he has stopped using his Erasure on him. This makes Endeavor realize that Tomura hadn't been using Quirks to perform the large leaps from before or to move around in midair but sheer raw strength. It is revealed by a restrained Kyudai that Tomura's strength may not be on par with All Might's, is still outstanding; and Eraser Head compares Tomura to a perfected Nomu. Calling him monster Ryukyu flies towards Tomura, only for the latter to use his enhanced strength to position himself just above Endeavor and slam him right down at her, sending both heroes plummeting into the ground.

Meanwhile, Gran Torino drops Deku and Katsuki in a safe place as he orders them to get as far away from Tomura as possible. Both Izuku and Katsuki want to fight Tomura, but Gran Torino refuses to let them do so since now that Tomura is the owner of All For One, they cannot take the risk of him taking the chance to steal One For All from Izuku, and if Deku lost One For All, that is the worst-case scenario. They see a large force heroes descend on the villain, but get shocked when they see Tomura's backup plan kick in: More than twenty of Nomus show up and attack the reinforcements. The confused Heroes wonders how they survived.

Back with Tomura, he stands triumphantly on the defeated Endeavor and Ryukyu. To add insult to injury, he raises his right arm, copying the triumphant pose Endeavor did at Kyushu, although mockingly asking him if he’s raising the wrong arm. Enraged, Endeavor tries to strike him again but Tomura dodges and moves away from him, telling that he now has better control over his Decay, but acknowledged that wasn’t able to save every Nomu but managed to free which Dr. Kyudai calls a miracle.

Two of the Near High End Nomu’s begin to rush towards Eraser Head, and Gran Torino moves to hiss location to protect him and tells Deku and Katsuki to hide. The Nomu are intercepted by Native and Kesagiri Man, but Tomura also dashes towards Eraser Head, intending to take out the Hero due as his Erasure is a nuisance to him. Shota is worried if he will die, but refuses to let himself be killed since he still needs to watch over and protect his students.

Rock Lock readies to defend Eraser Head from Tomura as Gran Torino tries to tackle him, but neither of them manages to stop the villain, who bypasses them and reaches his hand out to Eraser Head. Suddenly, Deku flies in and intercepts Tomura, pushing him away from his teacher. Katsuki also arrives, declaring that this time, it is their turn to save him.
