Experiment Gone Wrong [Book 1 Completed]

Fight or Flight

The groups all rotated around a few times, switching disaster zones. Shouta called everyone back in for a break, watching them all collapse in the center. The teachers grabbed the students bags and chucked them over. The class all grabbed their bags and pull out their lunches, stuffing their faces to reduce their hunger. Sighs of relief floated around as some flopped over to lay on the ground while others leaned on each other for support.

"Hey Kacchan?" Izuku asked, earning a hum in response from his tired friend who leaned on his back. "Once this is over, you wanna head out to the new cafe? It sounds really good and I want a treat after all this."

"Sounds fucking good. This whole thing is gonna fucking kill me soon," Katsuki replied, stuffing his face as he wiped sweat from his forehead. "I'm gonna ask the hag if I can stay over. You up for another movie marathon? Got some more fucking shit movies to watch. Startin' to pile up in the living room."

Heck yeah! The last movies were just fucking great! Yeah, they were dumb. But, they were funny as hell because they were so stupid.

Izuku smiled, nodding his head with a hum. "Sounds great."

The class, now all rested up and full, stood up with new energy radiating from them. Shouta assigned the groups to their next disaster zone, only to cut short when a swirling mass of purple and black caught his eye. He glanced over at Thirteen who had also caught sight of the mass. He swung around, gripping his scarf tightly as he opened his mouth, ready to order his students to run at any given moment. The swirling mass of purple and black started to expand out, a hand reaching out. It swatted to the side as a man dressed in black and covered in hands stepped out, bulky mutant villains stepping out after him.

"Everyone, head back up to the entrance, now!" Shouta yelled as he and Thirteen stepped in front of the kids. "Thirteen, you follow them. We don't know what these guys are capable of. Now run!"

The class staggered back, running up the stairs in hast with Thirteen in toll. All but 2 students ran. Tenya glanced back, coming to a halt when seeing Izuku and Katsuki standing still. He opened his mouth to yell out to them when he caught sight of Izuku shaking, seeing Katsuki trying to pull him along. Tenya rushed down, placing a firm hand on Izuku's shoulder, startling him. He went to tell them to follow the rest of the class when a scratchy voice stopped him.

"Ah, this is where you've been," he turned towards the villain covered in hands, his blood read eyes peering out from the hand over his face glistening in glee. "Its been awhile, hasn't it, I-zu-ku?"

Tenya whipped his head to his classmate, seeing his face clouded in fear. He was struggling to move, arms and legs shaking uncontrollably, eyes as wide as saucers as his pupils shrunk down. The bluenette looked up to the ash-blond, a stern look crossing his face as the blond looked back up at him. They both grabbed one of Izuku's arms each, dragging him with them back up the stairs as Shouta started to attack the villains. Izuku froze in his friends hold on him, watching as Shigiraki sent the purple and black mass up to them. He tried to scream out, but his voice was caught in his throat. He looked back at his friends, watching a portal appear in front of them. He mustered up strength in his arms, pushing his friends away as he fell into the portal.

It closed up, the greenette disappearing within the purple and black mass. Shock soon left Katsuki as he processed what happened. He screamed. Tears pricked the corners of his eyes till his emotions turned to pure rage, his hands crackling with explosions. He turned to the purple and black mass that had started to retreat back to the center of the plaza. He fired up explosions in his palms, launching himself forwards as he yelled in anger. His eyes caught onto a metal plate hidden in the warp gate. He grabbed the plate, setting off explosions as he slammed it into the ground, repeatedly punching the metal.

"GIVE HIM BACK YOU FUCKING BASTARDS!!" He screamed, ignoring the tears falling from his eyes as he continued to bash the plate in, not caring about the pain he may be causing. "GIVE HIM BACK!!"

He jumped back in time to see as massive hand reaching out to grab him. He exploded his way back over, slamming his fist into the mutants face and launched him back, tears streaming down his cheeks. He ignored the calls from Tenya to stop, only focusing on beating up the villains who've taken his best friend away from him once more. As he headed into the heat of battle between villains and his teacher, a few students decided to head down to aid them. Shouto launched a mountain of ice down, freezing some villains in place as he, Ejirou, Mina and Tsuyu followed suit. They rushed down the stairs, joining Tenya and ignoring Thirteen's calls to stop. They started to attack the surrounding villains, avoiding as many hits as they could while watching each others backs.

They continued to fight until almost all the villains were immobilised, laying on the ground unconscious or frozen. They all turned to the hand covered villain, watching as he scratched at his neck, blood red eyes peering out at the students and teacher in displeasure. He sighed out in frustration, fingers halting.

"Kurogiri. Get over here now and summon the Noumu." He ordered, all heads turning to the mass of purple and black, watching as he warped over to Shigiraki.

He opened another portal, a bulky bird monster stepping out, brain exposed as its eyes clicked over to the teacher and students. It let out a mighty roar, clenching its hands into fists. Katsuki tensed up, remembering the creature from his first encounter with one 6 years back.

"Not that stupid fucking creature again!" He turned to his teacher, wiping the tears from his eyes as they narrowed down. "Oi teach! Don't take this fucking thing lightly. It's seriously fucking powerful."

"Thanks for the heads up, Bakugou. Just stand back-"

"Not fucking happening! That thing almost fucking crushed my stomach and ribs with one hit! We're not fucking leaving you to deal with this shit alone." Katsuki cut his teacher off, hands crackling as mini explosions set off.

Shouta gave in with a sigh, giving his students permission to help. Shouto was the first to make a move. As the Noumu in a rage ran forwards, he shot a mountain of ice towards the creature, freezing it in place. Mina shot acid over at its brain, only to watch it disappear into a portal and land beside it. Shouta wrapped his scarf around the Noumu as Katsuki blasted around it, heading straight for Kurogiri, Ejirou in toll. He reached out to grab the metal plate within the mass when a portal appeared in front of him. Ejirou grabbed his leg, running to the side before throwing him back at the portal. He set off explosions on the metal plate once more as Ejirou kept Shigiraki at bay, hitting him back with hardened hands.

As the struggled went on, the doors soon burst open. All Might rushed in, U.A teachers following suit. He leaped down the stairs, landing a hard punch against the Noumu. Seeing no damage against the beast, he kept up a rapid sprawl of punches, breaking the ice that encased the beast before he launched him into the air, blasting him out of the USJ. Shigiraki managed to fend of Ejirou and remove Katsuki from Kurogiri who created a portal, disappearing in a matter of seconds.
