Forbidden Legacy

Prologue

Shigaraki Tomura crashed onto the floor of his hideout. His plan to kill All-Might had failed. He had lost Noumu, their ultimate weapon against the hero and he had gotten shot in the hand. All in all, he was having a really bad day.

"You were wrong, Sensei. All Might hasn't gotten weaker. Not at all!" Shigaraki cried at the glowing computer screen that read the words 'sound only'. On the other end was the most powerful villain known to man. Shigaraki's teacher. All for One.

"No, I wasn't." The distorted voice spoke. It played the voice with a pitched up and pitched down version overlaying, to create a disguised voice. Noone would know who was on the other end of the line if they weren't already familiar with them. "We simply underestimated him. It's a good thing your League of Villains came cheap. Although the loss of Noumu is significant. So much work, wasted." Sensei mused. Shigaraki chose not to ask how he knew of the fate of Noumu. Based on his knowledge of his master, it was probably a simple mind reading quirk. Sensei was full of surprises. A sudden thought emerged in Shigaraki's twisted mind.

"There was this one kid. He was about as fast as All-Might. We might've won if not for him." He explained. The kid in question was a green haired brat, who seemed all too eager to defend All-Might. Perhaps he knew that the hero was weakening as well? Or maybe he was just an easily scared child. Shigaraki hoped it was the latter.

"Oh? Were you able to get a sample, Kurogiri?" Sensei turned his attention to the warp gate user standing behind Shigaraki. He was dressed in a rather smart suit. His face was obscured by the mist that lent him his name, as was his hands. As such, noone really knew what he looked like beneath the obscuring layer. His voice came out in a low, deep tone.

"We were able to obtain a small blood sample from him and some more DNA samples from the other students." Kurogiri replied, recalling one particular kid that left some ice in his gate. Though neither of the villains could see their master, they were both certain he was grinning.

"Excellent. Send them to the lab at once. They will be most beneficial to the project." Sensei spoke in a rather pleasant voice. He then returned his attention to his apprentice.

"Do not be discouraged. This endeavor proved useful to us regardless of this setback. All we need are stronger troops." Sensei told his apprentice to calm him. Shigaraki was difficult to work with but very useful when he was focused.

"Shigaraki Tomura! You shall be known as the true symbol of terror across the globe!" He exclaimed before ending his communication. All for One rose from his seat, disconnecting his mask as he rose. He scowled at the device. His injuries in his last battle were troublesome, but not impossible to get around. In time, he would come to heal fully. In the meantime, his project needed to be checked. He passed through the secure metal door into a dark room, with only one object visible. A tube filled with a dark blue liquid, connected to a control console, on which a monitor displayed several vital signs. All for One grinned once more. The project was coming along excellently.

"My Magnum Opus. Soon you shall be ready." He mused before exiting the room, and leaving the boy sealed within. He then proceeded to exit his temporary laboratory. Kurogiri was waiting, the samples having been handed to a technician. He noticed his master appearing and opened a gate to his true lair. All for One walked into the gate with a smile on his face. Soon, everything would fall into place.

Two Days Later...

"Officer Tsukauchi! We found a lead on the USJ case!" A police officer chased the Detective in question, Tsukauchi, as he was wandering to his office to continue work on his most recent case. After meeting with the U.A staff to discuss the attack on USJ, he had locked himself in his office almost all night, double checking any records available for the villainous instigators of the conflict. He turned sharply towrds his colleague, the rings under his eyes very visible.

"What is it?" He asked with his interest piqued. He hadn't gotten very far in his work so he was desperate for any possible leads to follow up on. His colleague took a moment to catch his breath before standing up to the detective with a determined expression.

"We found a building with forensic evidence of Villain operations in the vacinity. With your permission, we have pro heroes ready to move on the scene." He explained. Tsukauchi's eyes were raised in surprise. What were they doing in a lab? What connection could that have to USJ? As if reading his thoughts, the other officer continued.

"We also found some trace amounts of DNA that matched some of the U.A students." He added. That was all Tsukauchi needed. Perhaps the villains were using the DNA to create more of those multi-quirked creatures the police found near the scene.

"Send them out immediately. I'll head in ASAP." Tsukauchi replied. The officer in front of him nodded and turned around, walking away from the detective while bringing his walkie-talkie to his mouth.

"We have clearance. You may enter when ready. Please excercise caution as this is a potential villain hideout." He spoke into the device. There was a short moment of static before he received a reply.

"Don't worry, we've got this." One of the heroes replied. He recognised the voice as Mount Lady, A fairly recent pro to hit the scene. She and Kamui Woods had been sent on the scene as they were the closest heroes available. They happened to work surprisingly well together, thankfully. Hopefully they could pull through on this.

At the Lab...

Kamui and Mount Lady stood in awe of the strange tube containing a nude teenager. They chose to avoid looking at them so as to not end up on some kind of watch list. But the boy's mere presence was offputting. Neither of the heroes recognised the boy from any missing person notices or wanted posters. They had surprisingly straight green hair and a muscular body. They also seemed to be not lacking in any area below the waist, but the pros swiftly diverted their attention elsewhere. The two looked to one another before moving slowly towards the control console in front of them. One button caught their attention immediately.

It read 'Eject Subject' and had a black and yellow border around it. Hesitantly, Mount Lady pushed the button. The room was illuminated in red light as the dark blue liquid contained within the tube flowed down througha vent at the bottom. Kamui Woods glared at his partner and she shrugged sheepishly in response. The alarm would be concerning if the facility wasn't eerily empty. Not a single person besides the heroes was seen in the facility.

The boy awoke collapsing into a kneeling position, one arm on the ground to stabilise himself as he coughed up the dark blue liquid he was entrenched in for... How long was it? He didn't know. He had no recollection of anything before now but flashes began playing a slideshow in his head. Images of a flaming face, a smiling old man in a cape and two crying children. Surprisingly, they both seemed to evoke an empathetic response from them. They seemed almost like...him? But neither of them seemd to look like him and some of the memory "slides" seemed to show one looking at the other. A few more people flickered through his mind as various names entered his head.

Midoriya. Todoroki. Bakugo. Kaminari. Which one, if any was his? Did he have a name? What did any of this mean? These thoughts raced through his head at high speeds as his glass chamber seemed to open. He opened his eyes and the resulting sight was blurry. It was hard to make out anything but a male and female figure stood before him. He would've asked their names but he passed out before he could. One thought stuck in his head as he collapsed.

Every one of his flashes seemed to bring to mind one word: Hero. That sounded like a good thing to be.

A.N: So, I was working on Black Sun Rising Chapter 2 and this idea flung itself into my head and I wrote it down. The result came from re-reading some of the manga of MHA and the Series of books by Andy Briggs. As well as a small bit of influence from Sonic Adventure 2 and Sonic Heroes. More specifically, Shadow the Hedgehog and his story. After compiling all of those things into my cauldron of ideas and stirring them with my spoon of writing, The result was Forbidden Legacy! I have a lot of ideas for this story but they should become clearer at the first chapter (This is just the prologue, after all.). In any case, feel free to Follow, Favourite, Review and all that jazz. I'll see you all later.

Sincerely,

Lord Terronus
