A/N: I do not own Transformers or My Hero Academia.
Aftermath
Within a low-lit bar in the city of Kamino, a warp gate and Tomura Shiagarki fell through to the floor, clutching his left hand now absent of three fingers, bleeding from his arms and legs.
Tomura: Ow! Shot in both arms and legs, not to mention I had my fingers cut off. All those underlings were wiped out. Even Nomu was beaten. We failed. Those kids were so strong—especially that one. And the Symbol of Peace wasn't weakened at all. You were wrong master! So wrong!
He complained to a TV screen that only said 'Sound Only'.
AFO: No I wasn't. We just weren't as prepared as we should have been.
Doctor: Thankfully, we failed under that cheap "League of Villains" name, not our own. And what about the creature the master and I created? That wasn't cheap considering I used a valuable and scares resource to create it and make it stronger. Where is Nomu?
AFO: Yes, why is he not with you?
Kurogiri: He was blown away.
Kurogiri answered bluntly, now dressed as a bartender.
Doctor: WHAT?!
AFO: Impressive. I had suspected that my old nemesis had some fight left in him, but not enough to send that Nomu powered by Energon flying.
Kurogiri: It wasn't All Might's doing.
Both the Doctor and All For One were shocked at the statement, even if their faces couldn't be seen. However, All For One soon became interested.
AFO: Oh?
Kurogiri: It was a student.
Doctor: A student?! After all that time and effort we spent creating that Nomu, testing and perfecting the low Energon supply we have, making him as powerful as All Might, a mere student sent it flying?!
Tomura: Not only that... but that brat... cut off three of my fingers!
Tomura then showed the television his left hand, which only had his ring and pinky finger left.
AFO: My, my. For a student to show such violence at a young age. It seems this society is getting sicker and sicker.
Kurogiri: It wasn't just that. While the other students reacted with fear and panic, this student remained calm and logical. He showed no fear for his own life and managed to even find my weak point despite our first encounter. I sent him to a zone where he would need to contend with over a dozen villains, but he managed to emerge victorious. Plus, after he was severely injured by the Nomu, he got back up minutes later and managed to defeat the Nomu before it could kill All Might. I've never seen power like that.
AFO: Describe it to me.
For the next several minutes, Kurogiri shared with his master the details of the student's battle with the Nomu, detailing all of his various abilities. When he was finished, All For One took a moment to stew over the information.
AFO: Impressive. Most impressive.
Doctor: Could it be possible this student also holds multiple Quirks?
AFO: No. From what Kurogiri said, his powers came from a blue glow around his body, so it must be one power, capable of doing multiple things."Much like One For All? Could this be the Ninth wielder?"
Tomura: But it wasn't just him. There was also the green-haired one. The one that moved just as fast as All Might and had a smash that seemed to be equal in power.
All For One's interest was piqued immediately. Maybe this green-haired boy was the successor.
AFO: Oh? What were the names of these two students?
Kurogiri: We don't know the identity of the green-haired one yet, but the one who defeated the Nomu called himself Optimus Prime.
A long moment of silence followed.
AFO: Prime, you say?
?: My, my. How interesting.
Both Tomura and Kurogiri flinched at the third voice, a voice they'd never heard before.
Doctor: What the–Where did you come from?! Who are you?!
AFO: What are you doing here?
The Doctor sounded surprised while their master sounded annoyed. Did the great one know this third voice?
?: Now now, Shigaraki, the old rusted one, not the little sparkling leaking red fluids on the floor. Is there any way to talk to your master?
Both Tomura and Kurogiri froze. This was their master's master?! And he even dared to call All For One by his true name?!
AFO: I've told you countless, I am not your student!
?: Keep telling yourself that, Shigaraki. As for you, little sparkling.
The voice then addressed Tomura, and despite not seeing the third voice and knowing nothing about it, Tomura felt a sense of dread form within him.
?: You're lucky all he did was cut your fingers off. If he was truly living up to his name, he would have taken your head off. This clearly shows how weak he is.
Tomura: Weak...?
?: He's too soft-hearted. He doesn't have the guts to do what needs to be done. He's a disgrace to the title of Prime.
Doctor: And how would you know such a thing?
?: Why shouldn't I? After all, I am a Prime.
All of them were shocked at the statement before Tomura gritted his teeth.
Tomura: So that's it. Is this brat related to you in some way? Some sort of bastard child, or nephew you threw into U.A. to ruin my fun?
The voice laughed.
?: Nothing like that. But we do have a connection. Something that runs stronger than blood. A special... legacy that connects us. But he doesn't know about me. Why should he? After all, those fossils tried their best to erase me from existence, only when I wanted to further the glory of the Cybertronian Empire.
They were all confused by this voice's words. What Legacy? Who are these old fossils? And what the heck is the 'Cybertronian Empire'?
AFO: We will discuss this later. For now, rest and recuperate Tomura. Use this as a valuable learning experience. For failure is the greatest teacher of them all. Soon enough the world will know and come to fear you, Tomura Shigaraki.
Tomura gritted his teeth, but he would follow his master's advice. Soon, he would have his revenge on All Might and those brats, especially the green-haired one and Optimus Prime.
Tomura: "Just you wait, Optimus Prime! Next time we meet, I'm taking your arm!"
A few hours had passed since the villains escaped and the police had arrived. All the villains were being escorted in chains to the police vans.
Detective Naomasa Tsukauchi was with Class 1-A and was doing a headcount.
Tsukauchi: ...16, 17, 18, 19. Everyone seems to be unharmed, except for that boy whose arms and legs were all messed up and the kid who passed out.
Toru placed her gloved hand on Mashiro, causing him to look at her.
Toru: Ojiro, I heard you were a really good fighter. I had no idea you were so strong!
Mashiro: I had no idea, except for Prime, that I was the only one on my own. I survived using hit-and-run tactics. But from what I heard, Prime is much stronger than me. I heard he took on over a dozen villains by himself and managed to walk away and help the others. So where did you end up fighting Hagakure?
Toru: The landslide zone.
She answered while pointing at Shoto.
Toru: You wouldn't believe how strong Todoroki was. He's amazing!
Mashiro: You don't say! We'll I'm just glad you didn't get hurt.
Shoto overheard their conversation and mentally berated himself for his carelessness.
Shoto: "I didn't even know she was there. I could've frozen her."
Yuga: Aren't you wondering about Moi? Where was my sparkling light?
Everyone ignored him as Fumikage, Koji, Eijiro, and Denki were talking.
Fumikage: Interesting. So the people you fought were also low-level thugs?
Eijiro: Yeah, they messed with the wrong kids, huh?
Denki: Yeah, but it seemed pretty bad for us until Optimus showed up.
Yuga didn't let it bother him as he turned to Mezo, Rikido, and Hanta.
Yuga: Did you miss me?
Hanta: So Prime was the one who put that hole in the dome after all. I still can't believe he did something All Might couldn't.
Rikido: That took some hardcore power. I didn't know he had it in him.
Mezo: Yeah, it was crazy. Guess that's our class rep for you.
Yuga then turned to Tsuyu, placed a hand on her shoulder, and asked.
Yuga: Where do you think I was?
Tsuyu: Uh... where?
Yuga then did he sparkling and looked at the camera.
Yuga: It's a secret.
Tsukauchi: Let's go ahead and get these students back to the main campus. They've been through a lot. We don't need to question them right away.
Tsuyu hopped like a frog to stand in front of him.
Tsuyu: Detective. What about Mr. Aizawa?
Tsukauchi held up a phone and put it on speaker, connecting them with the doctor overlooking Aizawa.
Doctor: The bones in his arms are splintered and he's got facial fracturing. Fortunately, there doesn't seem to be any serious brain damage. But his orbital floor has been almost destroyed. We have no way of knowing whether his eyesight will be impaired once he's healed up.
Tsukauchi: There you have it.
Tsuyu: Ribbit.
Minoru: Not his eyes.
Mina: Um, sir, what about Thirteen?
Tsukauchi: There's no need to worry there. Despite some pretty bad lacerations to the back, Thirteen is gonna pull through, good as new.
Everyone sighed in relief at the news.
Tsukauchi: And All Might is also without any serious injuries. He's in the nurses' office right now. Recovery Girl's power should be all the treatment he needs.
Ochaco: What about Deku?!
Tenya: How's Midoriya?
Tsukauchi: Midori–Ah, Recovery Girl is taking care of him too. He's fine.
They sighed in relief.
Ochaco: Oh, thank goodness.
Momo: What about Optimus?
Eijiro: Yeah, how's OP doing? He just collapsed all of a sudden.
Tsukauchi: Well from what I've heard he doesn't appear to have any physical injuries. It seems he may have just fallen unconscious from an overuse of his Quirk. Which can be dangerous in and of itself. But knowing that kid, I'm sure he'll pull through just fine.
Once again, they all sighed in relief. However, they were confused as to how Tsukauchi could have known Optimus enough to say that last statement.
Tsukauchi: Now, let's get you back to class.
Everyone: Okay.
Tsukauchi then turned to a police officer with a cat head and a little bell around his neck.
Tsukauchi: Sansa. I still have some business in the nurse's office. I'll leave this to you.
Officer Sansa gave a sharp salute.
Sansa: Yes sir.
Mina: It's a cat?
Ochaco: Aw look at his little bell.
Meanwhile, Katsuki was staring at the U.S.J. building with a contemplative look. He thought back to two moments, when Robo-Boy took the hit to save him, and when Deku jumped to stop the villains from hurting Robo-Boy after he sent Nomu flying.
The feeling of helplessness, that weakness that he needed to save. He hated it. he clenched his fist in anger.
Eijiro: C'mon man! We're going back to class, now.
Katsuki: Yeah, yeah. I heard him you idiot.
Everything hurts.
All Optimus Prime could feel was pain from his toes up to his forehead. At least that was a sign he was still alive. Though given this pain, he was slightly wishing death would come to claim him.
?: Why am I not surprised to find you back here?
Optimus turned his head to see Recovery Girl look down on him with a look of annoyance and pity. He craned his neck as best he could and saw he was in the Nurse's Office back at U.A.
Optimus: I'm sorry.
Recovery Girl: Don't say such things unless you mean it. I know one way or another, you'll just find your way back here. I swear at this rate, you'll become even worse than he is.
Optimus groaned as he moved to sit up. His muscles ached and his head was spinning, but he's had worse.
Recovery Girl: While I'm relieved you didn't come in with broken bones or a beaten body, you were still dangerously close to dying. I don't know what all happened, but you used your Quirk too much and pushed yourself too far. And from what I've heard, even when you've had struggle standing, you still pushed yourself to use that Energon in your blood to move.
Optimus: It was the only way to save Izuku from that villain.
Recovery Girl: I know. Which makes me even more mad, since I can't hate you for that.
Optimus laughed, even though it was painful to do so. She reminded him so much of Ratchet. Always worrying and fussing about how much he and his fellow Autobots injured themselves.
Recovery Girl: Still, that doesn't mean it's okay to always push yourself like this. Imagine how hurt everyone would be if you suddenly died.
Optimus looked away. There was a time when such a tactic would work on him, but now...
Optimus: I have no one.
Recovery Girl: Hogwash!
Optimus looked at her with a raised eyebrow.
Recovery Girl: Don't pull that whole 'I'm an orphan so no one cares about me' crap on me! So what if you don't have any blood family? That doesn't mean you can't find one of your own. And besides, your friends would be devastated.
Optimus: My friends?
Recovery Girl walked over to the entrance and opened the door.
Recovery Girl: He's awake! You can all come in, but only for a few minutes.
On cue, nearly every student from Class 1-A entered the Nurse's Office, except for Katsuki, Shoto, and Izuku. The former two went home while the latter was resting in a place away from Optimus for the time with All Might.
Eijiro: Hey OP! Good to see you alive and kicking!
Toru: Yeah, we were worried when we heard you suddenly collapsed!
Rikido: But man that fight with the villain was so epic!
Hanta: Yeah! I had no idea you were so strong!
Mezo: How were you able to sprout those wings of light?
Mina: Have you been holding out on us OP?!
Denki: He has! He pulled off a Matrix-level dodge before shooting a villain in the face! It was awesome!
Kyoka: Yeah, it was pretty awesome.
The rest of his classmates came in and expressed such concern over him. Optimus was slightly surprised. He'd only known them for four days at the most, and they were already this concerned about him. He had to admit, having people care about him made his heart melt in happiness.
However, he looked behind the others and saw that Tenya was standing away from the group with his head hung low in shame.
Optimus: Tenya? Is something the matter?
Everyone's attention soon turned to Tenya who flinched at the attention before he took a deep breath. He then approached the bed and bowed his head dramatically.
Tenya: I'm sorry! I'm sorry for leaving you all! I'm your Class Secretary and I still left you all in a perilous situation. Please forgive me!
There was silence for a long moment before Optimus spoke, his words surprising everyone.
Optimus: No.
Everyone was surprised by his answer and Tenya's stomach dropped even further.
Optimus: Because there is nothing to forgive. Rather, I would like to extend my heartfelt thanks to you Tenya.
His words shocked Tenya.
Tenya: 'Thanks'? But... I left! While all of you were struggling to live, I escaped and would have been the sole survivor if I couldn't find help!
Optimus: But you did. You managed to not only get All Might, but even all the teachers of U.A. and bring them to the U.S.J. just in time. You saved us. Thank you Tenya.
Tenya was almost moved to tears, truly touched by Optimus' words, but he wiped his face, took a breath to calm himself, and smiled, the guilt he felt for thinking he abandoned his classmates now gone.
Tenya: Thank you for your words Prime!
Optimus would usually ask Tenya to call him by his name, but he was too tired to argue.
Recovery Girl: Now I know you kids would like to talk to your class rep more, but he still needs more rest. So if you can please leave the room so that he can rest.
Tenya: Of course Recovery Girl. We wouldn't want to get in the way. Let's all head home everyone! We need to be ready for when classes resume.
Mashiro: Is school all he can think about?
One by one, everyone began to leave the hospital room, waving their goodbyes to Optimus. Soon enough, everyone left except for one person.
Optimus: Is something the matter Momo?
Momo: If you weren't in a hospital bed and already exhausted from the day, I would slap you so hard right now.
Optimus flinched at her statement. But he blinked when he saw tears gather in her eyes. Before he could say anything, she rushed to him and gave him a gentle hug.
Momo: But right now, I'm just so glad! So glad that you're okay!
Optimus was taken off guard. To be honest, he's not used to such physical contact, since not many people hugged him when he was the Autobot leader. But he went with his gut instincts and returned the hug, wrapping his arms around her and patting her back to calm her down.
Eventually, after a few minutes of quiet sobbing, Momo let Optimus go and coughed to herself, trying to regain her composure.
Momo: Apologies for my behavior. It must've been an unpleasant surprise to you for me to suddenly do... that.
Optimus: It is quite alright. I understand that today has been a very taxing day, for everyone.
Momo: Yes it has... but not you.
Optimus looked at her with confusion.
Momo: You may try to hide it but I could see it clear as day when the villains first showed up. While most of us were panicking, you were calmly assessing the situation and trying to find out the best plan to move forward with. Plus with how you handled Kaminari's hostage situation, you gave off the impression that you were experienced in dealing with situations, and not just from training.
Optimus was surprised that she was able to figure all that out. She was very observant.
Momo: My question is... how? How were you able to be able to stay so calm? How did you know what to do?
Optimus could see the pleading look in her eyes. She wanted to know so that she could know how to handle those situations. But his knowledge came from the experience of a long and brutal war, something he wanted no one else in existence to experience. He looked down at his hand in contemplation, recalling something he once said to Arcee.
Optimus: Let's just say that wisdom cannot be granted Momo. It must be earned. Sometimes... at a cost.
Momo was surprised at his words, and noticing the forlorn look in his eyes, she frowned in sadness. What cost did he have to pay to gain the wisdom he had today?
Before anything else could be said, Recovery Girl, who was still in the room, cleared her throat.
Recovery Girl: Didn't I tell you to let him rest?
Momo, and surprisingly Optimus, blushed. They forgot she was in the room!
Momo: I should get going! I'll see you in class Optimus!
Momo was about to leave but Optimus stopped her.
Optimus: Momo. In light of these events, may I offer a quick suggestion to help you improve?
Momo took a 180 and looked toward Optimus with excitement in her eyes.
Momo: Yes!
Optimus was caught off guard by her excitement but smiled.
Optimus: I think you should change your hero costume.
Momo blinked in confusion as she looked at her costume.
Momo: Why? What's wrong with it?
Optimus: It is too impractical. For starters the heels.
He gestured to her feet.
Optimus: I am by no means an expert in footwear, especially for females, but from what I do know, where heels for long periods can cause pain in your feet, not to mention the weight distribution can create issues in your knees, ankles, hips, and lower back. I've even read that extreme cases can lead to arthritis. I noticed during our duel during the battle trial that you did have trouble with your footing due to the heels
Momo had to admit, Optimus had a point. While she was used to wearing heels for such a long time, she did have moments where her feet started to hurt. It wouldn't do good if it kept her being able to operate at 100%.
Optimus: Another thing is the bookcase on your back waist.
Momo: What's wrong with it? I need to look through the books at times to be able to create complex objects.
Optimus: I understand. However, the position where the bookcase is placed on your body could have disastrous consequences. If you fall and land in a certain way on your back, the bookcase could damage your spine and you wouldn't be able to walk anymore.
Momo shivered at such a scenario. To think her career as a Pro Hero, possibly her life, could end just because of a simple design flaw of her costume. That would be as tragic as it would be embarrassing.
She mentally chastised herself that she hadn't seen that flaw in her hero costume earlier.
Momo: What could I do to fix that?
Optimus: I would suggest carrying around a tablet that contains the information you need to create such complex objects. It would be lighter as well so it would not inhibit your movement.
Momo nodded. This was getting exciting! She never got the chance to design her hero costume. She just put in several key suggestions and went with whatever the support company her family partnered with developed.
Optimus: Lastly, you need to do something about your exposed skin.
Momo: But I need my skin to be visible to use my Quirk.
Optimus: I understand. But having that much skin exposed could lead to further endangering yourself. Having that much exposure leaves you more vulnerable to knives, flames, the cold, etc.
Momo: Then what should I do?
Optimus thought about it for a moment before he remembered what the author did for Toru.
Optimus: Perhaps you could create the costume using your DNA. I've read that many heroes that require parts of their body to use their Quirks have their costumes designed in a way that it becomes a second skin to them. Perhaps you could consult with Toru about coming up with a way to use your DNA to create the fabric of the costume.
At once, it felt like a lightning bolt had struck Momo, shattering the lightbulb that would normally turn on. Her onyx eyes soon sparkled in excitement.
Momo: That's genius! I can't believe I never thought about it! Oh, I can't wait to get home and start working on it! With the break we have from school, I'll have plenty of time to come up with the perfect idea! Oh, this is so exciting!
Optimus was caught off guard by the excitement Momo was displaying, thinking that it didn't fit her heiress character. But he didn't mind. He preferred this side more. He thought Momo looked cute.
He then blinked.
Optimus: "What was that?"
Momo: Thank you so much for your help Optimus!
Optimus merely smiled, glad to see she looked so much brighter since she came in here.
Optimus: I am happy to help.
Momo: I'll see you when classes resume! Goodbye!
And with that, Momo left the room, leaving Optimus and Recovery Girl alone. The latter had a knowing smile on her face as she looked at Optimus.
Recovery Girl: That was a nice thing you did for her. Most people wouldn't go so far as to help someone change their entire hero costume.
Optimus: Momo is a good person and a valuable friend. I want to do everything in my power to help her, and all my other classmates, succeed. Both as their leader and as their friend.
Despite his heartwarming answer, Recovery Girl sighed in annoyance.
Recovery Girl: "He's so dense. That girl is so obviously into him. Even she doesn't realize it." Anyway, while I did say you should get some rest, some people need to see you before you do.
Optimus looked confused as Recovery Girl moved to the door and opened it.
Recovery Girl: You can come in now.
Then three people entered the room. First was Izuku, who had several bandages wrapped around him, but he didn't look too banged up. Second was a face Optimus hadn't seen in nearly a year, Detective Naomasa Tsukauchi. And the third was what could be best described as a walking skeleton man with blonde hair and blue eyes. But Optimus knew immediately who it was.
Optimus: All Might?
The others all flinched, surprised that Optimus immediately got it right. All Might soon sighed.
All Might: I should've known it would have been foolish to try and hide it from you, Young Prime. Yes, it's me, I'm All Might. But in this form, I go by Toshinori Yagi.
Soon enough everyone took a seat around the Prime's hospital bed.
Toshinori: I take it you have some questions?
Optimus: How did you end up like that? I take it you didn't always look like that.
Toshinori: Starting with that elephant in the room aren't we? Prepare yourself though, this isn't going to be pretty.
Toshinori lifted his shirt and Optimus, who had had his fair share of hideous and glaring scars, couldn't help but gasp. It covered most of the left side of his upper body and was spreading outward like an infection.
Optimus: Primus...
Toshinori wasn't sure who 'Primus' was but guessed from Optimus' tone that he was surprised.
Toshinori: Yeah, not pretty. I got into a nasty fight with a villain over 5 years ago. I lost my stomach and my lungs and respiratory system were shot. Thanks to this I can only enter my muscle form for a limited time daily. I also can't eat most solid foods anymore because of this.
Optimus was shocked at the terrible scar, but a detail Toshinori mentioned stuck out to him.
Optimus: 5 years ago... I see, so that explains it.
The others were confused.
Tsukauchi: What do you mean?
Optimus: In my research of heroes, particularly All Might, I noticed that around 5 years ago, sightings of him began to decrease at a steady rate. Not so much that it was noticeable, given the influx of heroes in Japan. But as time passed, people began to see less and less of All Might throughout the day. Today, the most anyone sees of you is around three hours.
The three were surprised at his observation skills. So far, no one has been able to make such a connection. And if they did, nobody came forward about it, even in the fan theories.
Izuku: "Even I didn't notice it."
It's true. Despite being a massive All Might fanboy, even he never noticed that the Symbol of Peace seemed to be seen less and less. Not until that fateful day that his life and destiny were forever changed.
Optimus: I had originally assumed it was because you were getting old.
Suddenly, Toshinori began to spit up large amounts of blood, much to the shock of everyone in the room!
Izuku: ALL MIGHT?!
Optimus: ARE YOU OKAY?!
The only ones who weren't shocked were Recovery Girl and Tsukauchi, both having seen this enough times to get used to it... mostly.
Eventually, Toshinori calmed down and stopped the geyser of blood coming from his mouth.
Toshinori: Don't worry Young Prime. I'm fine. This just tends to happen whenever I get excited or shocked.
Optimus: I am so sorry for my comment! I had no idea it would make you vomit blood!
Toshinori: It's alright Young Prime. I forgive you. I'm mainly here to thank you.
Optimus: Thank me? For what?
Toshinori: What not? By all means you were the hero of this entire incident. I heard when everyone was shocked at the appearance of villains, you were the first to act and even managed to take some of them out. You also managed to fight off over a dozen villains by yourself before regrouping with Young Yaoyorozu, Jiro, and Kaminari, even saving the latter from a villain. Then you saved Young Midoriya, Asui, and Mineta from the ringleader and Nomu, and even fought the latter briefly before I showed up. You even managed to react faster than me to save Young Bakugou from the Nomu. And when it felt like I would die fighting that Nomu, you miraculously stood back up and saved me from that monster before defeating it yourself. If that's not heroic, I don't know what is.
Optimus, however, shook his head.
Optimus: You give me too much credit All Might. I merely did what any other hero student would do, what we all did in this situation. I believe others are the real heroes of this tragedy. Tenya managed to escape with the help of Thirteen and his classmates, getting help from you and the rest of the school. Momo managed to incapacitate a large number of villains and protect two of her classmates long before I arrived to help. Mr. Aizawa was also indispensable, taking on those villains that first arrived. Katsuki, Eijiro, and Shoto also played key roles in saving your life. And above all there was Izuku.
The green-haired boy's eyes sparkled as Optimus looked toward him.
Optimus: Even when he could barely control his Quirk, and with the odds stacked against him, he managed to overcome them and save his classmates, including myself at the end. Thank you once again for that Izuku.
Izuku was moved to tears at Optimus' words of praise.
Optimus: But there was also you and the other teachers as well All Might. Without your arrival, I fear what would have happened to all of us. So thank you, for saving us, sir.
All Might was almost moved to tears. To hear a student thanking him so earnestly made his heart melt in gladness. He was lucky to have someone like Optimus as his student.
Tsukauchi: You sure are one of a kind, Optimus Prime. Most people would end up taking all the glory for themselves, but not you. Humility is a good trait to see in a young hero.
Toshinori nodded.
Optimus then looked down in shame.
Optimus: Besides, I'm partly the reason why you almost died today All Might.
They were all confused.
Toshinori: What do you mean?
Optimus: The Nomu, somehow had Energon running through its veins.
Tsukauchi subtly pulled out his notebook and wrote the word 'Energon' with a '?'.
Izuku: What's Energon?
Optimus: Energon is what is flowing through my blood. It gives me enhanced strength and power far superior to a normal human, without it being a Quirk.
The others were all surprised. Optimus claimed his blood allowed him to achieve superhuman feats without a Quirk. Tsukauchi wasn't that surprised since he was there when the one Doctor examined Optimus and practically begged the student for more blood samples.
Optimus: And it seems that the villains somehow managed to get ahold of my blood to create the Nomu.
Toshinori: How is that possible?
Recovery Girl: I think that may be my fault.
Everyone turned to Recovery Girl.
Recovery Girl: For the past year, me and Optimus have been studying his blood. It was unlike anything we've ever seen. It was even more compatible with blood types than type O's. And it was self-replenishing. We hope that his blood can be used to help those with blood-borne illnesses, but we needed many more tests to determine if it was 100% safe. Someone must've found out about it and stole the blood.
Optimus: It's possible, which means this whole incident was my fault. If it wasn't for me–
Toshinori: Stop right there.
Optimus was interrupted by Toshinori.
Toshinori: You had no possible way of knowing that your blood would be used for evil. You gave that blood away freely out of a desire to help those who were struggling. Sadly though, this is something the most heinous of villains seek to always do. Take something meant to heal and help others and turn it into something twisted and ugly. But that was in no way your fault.
Tsukauchi: He's right. Take this gun I have here.
He stood up and showed off his gun in its holster.
Tsukauchi: This gun can be used to end lives with just the pull of the trigger, but it can also be used to save lives. It doesn't make it good or evil. What matters is the person who pulls the trigger. Same with your blood. It matters how it's used and by whom, not that it's there.
Izuku: Yeah! And besides, you managed to defeat the Nomu! So in a way, you've made up for your mistake, not that you made any in the first place.
Optimus had a grateful smile at their words. While he still felt a little guilt over the Nomu having Energon, he knew they were right.
Toshinori: So allow me to thank you for what you've done. You've proven you have the makings of a great hero...
He then took a deep breath.
Toshinori: ...And the right to learn our secret.
Optimus raised an eyebrow. He looked toward Izuku and saw his eyes widening. He soon connected the dots.
Optimus: You gave Izuku your power, didn't you?
Once again, they were all shocked.
Optimus: I noticed from the beginning that Izuku's power had some similarities to yours All Might, despite it injuring him greatly, though that could be because he could not control the power yet. I also noticed your favoritism for Izuku over the other students. You've known him longer than others, and see him in a more positive light, and he does too, beyond that of a simple fanboy. Plus, how he seemed to be the most concerned about you as opposed to all of us.
Once again, they were all left stunned by Optimus' deduction skills.
Toshinori: Once again, you are correct Young Prime. Yes. I did indeed transfer my Quirk to Young Midoriya. The name of this power is... One For All.
For the next several minutes, Toshinori shared with Optimus everything there is to know about One For All. How it was a scared torch passed down from generation to generation. One person cultivates the power before passing it down to another who does the same. He explains it's gone down from one user to another 8 times, with Izuku being the 9th wielder.
As they were explaining the power, Optimus couldn't help but draw parallels with the Matrix of Leadership. The Matrix was a repository of the Primes that was passed down for a time before eventually landing with Optimus.
Toshinori: Now that you know our secret, please, we ask you to keep all that you've learned here to yourself. If people knew Quirks could be transferred to another, it would cause chaos.
Optimus: I understand.
He truly did understand. There would be mass panic and people scrambling to acquire the power for themselves. It was like what the Primes did with the Matrix of Leadership, and how Optimus wanted to keep him and his Autobots secret while on Earth.
They all soon sighed with relief.
Toshinori: Thank you, Young Prime. "Now here comes the hard part."
Toshinori's face soon became serious as he turned to his protege.
Toshinori: Young Midoriya, you should go home for the day.
Izuku was shocked by the suggestion.
Izuku: Huh? It's fine. I don't mind staying for a bit longer.
Toshinori: Still your mother must be worried.
Izuku blinked several times before he cried in panic.
Izuku: Oh no! She must be so worried! I gotta get home before she ends up almost flooding the building again!
Optimus: "Again?!"
Hearing such an outcome could come from a human crying surprised Optimus, but to hear it had happened before was unbelievable!
Izuku: I'll see you when school starts up again Optimus!
Optimus smiled.
Optimus: Farewell for now Izuku.
And with that, Izuku left the room.
Now that he was gone, Optimus turned his attention to Toshinori and Tsukauchi.
Optimus: What was so important that you made Izuku leave the room?
Both the hero and detective sighed.
Toshinori: I just didn't want him to be here for this next part.
Optimus: And what is that?
Toshinori and Tsukauchi both looked at Optimus with serious and almost hostile expressions.
Toshinori: I'm sorry to do this to you Young Prime. I truly believe you have the heart of a true hero, but after seeing how you defeated the Nomu, there's something I need to know.
Tsukauchi: Multiple students saw that you somehow generated dragon wings of light from your back, as well as changed the floor to a softer substance. Two very different Quirks, especially from the one that's on your file, which didn't come into existence until about a year ago after you and Nezu talked. I did some research and according to this, no one named Optimus Prime existed before the Sludge Villain incident. So the question we have for you is...
The detective's eyes narrowed.
Tsukauchi: ...Who are you Optimus Prime?
Internally, Optimus sighed. He should have expected such an interrogation. What he did all but showcased he had multiple Quirks, like that Nomu, and he did admit the Nomu was created using his blood, so he understood their nervousness. But what should he do? Lie? Optimus never liked lying, that was Megatron's area of expertise. But if he told the truth, would they even believe them?
However, at the end of the day, there was no battle about what to do or not. They told them the truth regarding All Might's power, so it would only be right for him to share his origins. Whether or not they believed him was up to them.
Taking a deep breath, Optimus spoke.
Optimus: My name is Optimus Prime. I am an automas robotic organism from the planet Cybertron. Also known as an Autobot.
Another hour passed before Tsukauchi and Toshinori left the room, exhausted looks on both their faces. Optimus had spent that last hour telling them about his origins and homeworld. He went into little details about the war, how he ended up in this world, and how he unlocked his power
Tsukauchi: That was...
Toshinori: ...Yeah. He didn't lie, did he?
Tsukauchi shook his head no. His Quirk, Lie Detector, would instantly notify him when someone would lie. It worked well for interrogations like they just had but...
Tsukauchi: No, he didn't. But remember, if someone truly believes what they are saying is true, then my Quirk won't pick up on the lie. So either he's so crazy he believes that he's some living alien robot from another dimension that came to this world and became a human...
Toshinori: ...Or it's all true. And I would call Prime many things, but mentally insane would not be one of them.
Tsukauchi: If his story about fighting in a civil war across his homeworld is true, then it would explain how well he was able to handle the situation, not to mention his combat skills. And also... those scars.
Toshinori nodded grimly. Optimus had shown them the countless scars that covered his body. The sight caused Toshinori to vomit blood, and not just because of his condition. He was no stranger to scars on the body, but to see that many, and on one so young. Well, not 'young' per se but still. It was horrifying.
Toshinori: So... what do we do now?
Tsukauchi: Well I can't exactly tell the higher about about this, not if I want a psych evaluation or end up getting fired. He mentioned he told Nezu about his past, so let's check with him and find out what to do from there.
Toshinori: Good idea.
He then looked to the side.
Toshinori: Besides, where he comes from doesn't matter. Even if he was a product of All For One's making, he's proven that he's a true hero today by fighting alongside his classmates and saving me. I know it.
Tsukauchi: Yeah. Besides, they would throw a fit if their strongest student was expelled simply for reasons he had no control over.
Toshinori: You're still not seeing the bigger picture Tsukauchi.
The detective looked at the Pro Hero in confusion.
Toshinori: I told you before that this class was strong, and they experienced something so other hero students had this earlier in their career and survived. They even came out stronger for it. They caught a glimpse into the life of a Pro. But Optimus, he's beyond that. He already knows the ins and outs of what makes a hero, a true hero. With him leading this class, I know that they will become the brightest lights this world has ever seen.
Optimus sighed as he sat back in his hospital bed.
Despite not saying anything, he knew both Toshinori and Tsukauchi doubted his story. Who wouldn't?
But still, they took a chance and believed in him, which he was grateful for.
As he lay in bed, he turned and saw the setting sun from his bed.
As he stared at the glowing orb of gas and fire descending below the horizon, Optimus was hit with the revelation that this world wasn't as peaceful as it first appeared. There was evil lurking in the shadows, looking to throw this world into chaos, like Cybertron. But Optimus wouldn't let that happen.
He looked at his hand and clenched his fist in determination. Those villains made a big mistake in attacking them today. They made themselves an enemy of Optimus Prime. And he wouldn't let them go.
He would defeat these villains, he would continue to guide his classmates to the path of heroism, and he would continue to protect the innocent. Because that is who he is and who he always will be.
Optimus: Freedom is the right of all sentient beings.
And as always, Optimus Prime would fight to protect that right. No matter the cost to himself.
