Chapter 3: Full Power Revealed
All Might's POV
All Might was angry for many reasons. Earlier he had been talking with Principal Nezu about focusing more on teaching due to his exuberance earlier that day. And he was right. As Nezu pointed out, he had a duty to his students that he had to stick to. But for some reason, Thirteen and Aizawa hadn't picked up any of his calls. Something didn't sit well with the Symbol of Peace. All of a sudden a panicked and exhausted Iida broke into the room, thankfully he had been in his muscular form, and explained that villains had attacked the USJ. Nezu and All Might shared a look of anger before All Might left immediately while Nezu called on the teachers.
As he walked into the building he studied the expressions of his students waiting at the entrance. HIS students! They were terrified as not only Thirteen looked injured but Aizawa as well. He knew that the best thing he could do right now was to reassure them so he took off his tie and announced "Fear not students. Because I am here" he declared.
Percy's POV
'Damn that guy looks similar to Superman. And the way the punks and Izuku are reacting, that must be All Might. Well points for originality' Percy thought to himself as he studied the new arrival who was standing on top of a long stairway.
The low level thugs stood scared as they tried to psyche themselves up but, to Percy's shock and awe, All Might had just ran down the stairs and punched every one of the punks out leaving only the warp villain, Shigaraki, and Nomu standing in what felt like 2 seconds.
"Di Immortales! How fast is he?" Percy asked his young companion who was only staring at All Might in horror 'Ok unless he's seen that guy go a lot faster and somehow that was slow or he knows something else. Either way we can't stay here' Percy thought to himself. "Come on Izuku, we have to move now. No way in Hades am I going to let those three make hostages out of us" he said as he grabbed Midoriya and started running, somehow feeling a lot faster than before.
"Nomu kill the.." Shigaraki started to order but all of a sudden a swift wind flashed by him and the Nomu as All Might grabbed the two heroes and sent them closer to the stairway. Percy blinked as he took in his new surroundings as the towering behemoth stared down at him, unsure what to make of Percy. That was until Midoriya stepped in front of Percy and clarified "Wait All Might he's not one of them. He actually saved me, Tsuyu, and Mineta, and healed Aizawa as best as he could. He also tried to take down those villains. His name is Percy Jackson. His water manipulation is off the charts"
All Might's POV
As he studied the young man next to Midoriya-shounen, he couldn't help but notice the scars on his front. This wasn't a vigilante using his powers to claim fame. This man was experienced. His green eyes, while currently in shock, told All Might that despite his youthful appearance, he was always ready. So when Midoriya mentioned the name Percy Jackson and water manipulation, his eyes narrowed 'Could it be? No he's far too young, and Midoriya-shounen only mentioned water, the legend stated he could control the four elements. Questions for later but now the villains need to be stopped.' "Thank you for protecting my students Jackson-shounen but now it is my turn to deal with them" All Might stated as he turned to the three men back at the fountain.
Percy, however, walked next to him and said "Call me Percy, big man and no problem. But just for reference, the brain monster is stronger than anything I've faced before and can take a lot of hits, not to mention it can regenerate as well. The creep with the hands said something about it being designed to take you down." All Might turned to Percy with a smile and gave him a thumbs up as he rushed towards the massive beast crossing his arms
"CAROLINA SMASH!"
Midoriya's POV
'This is bad. Earlier Thirteen and Aizawa were talking about All Might not being here. Thirteen had secretly put up three fingers, meaning that he had exhausted himself already. And now he's about to take them on.' Midoriya thought to himself as he tried to figure out what to do
"Come on, let's back him up" Percy said all of a sudden, shocking Midoriya. "What? You look worried which means you know something about him that could weaken him. Besides I didn't like the look of that creep when All Might came" Percy explained himself. Midoriya's eyes started to water before he shook his head and nodded, bringing a smile to Percy's face as they rushed towards the action.
All Might's POV
'Alright then Jackson was definitely right about the villain being strong as well as him taking multiple hits. But I have to play dumb to that' All Might thought to himself as he traded blows with the Nomu. "Doesn't matter exactly where I punched you, does it" All Might asks, knowing the reason why but hoping one of the villains would talk.
"That's because Nomu here has Shock Absorption All Might. The only way you could beat him is to slowly wear him down. Of course that's not going to be possible as he rips you into pieces." the turquoise haired villain taunted in response.
"Thanks for telling me how to beat him" All Might thanked as he ducked under Nomu's wild swing and got behind him. He then grabbed Nomu by the waist and lifted him up to deliver a powerful german suplex which caused debris and smoke to fly.
Percy's POV
Percy and Midoriya rushed to where the smoke was as he had a bad feeling about the situation. Shigaraki taunting while his specter pet stood behind him just left him uncomfortable as if they knew the hero would try that. Midoriya though started to hope for the better "Maybe there wasn't much to worry about" he said a bit too naively.
Percy shook his head as he kept running. "Where I'm from I always expect the worst outcome that way I don't get shocked" Percy snapped as the dust cleared. To Midoriya's horror half of All Might's body was across two warps while Nomu's torso and legs were up in the air and its face and arms were underneath All Might grabbing him by the ribcage. "Of course they'd pull a cheap stunt like that" Percy curses as the two run faster to All Might's aid as claws dug into the hero's side.
The specter stepped forward as he contemplated his work. Percy however noticed a metal brace within the swirling shadows indicating the possibility of a body. The two got closer as All Might slowly started to sink. Percy tried to work out a plan but Midoriya ran past him and jumped with a fist raised high. 'No No No No NO! Not another one! Not again!' Percy panicked as he chased Midoriya only for the specter to phase in front of the two. Percy's fears were getting worse as Midoriya got closer and closer to a warp gate.
All of a sudden a black and orange costumed blonde with a literal grenade gauntlet shows up and blasts the gate yelling "GET THE HELL OUT OF MY WAY DEKU!" stunning both Midoriya and the specter long enough for him to grab the top of the metal brace and slam the specter to the ground. At the same time ice covered Nomu's right side completely from its leg all the way up to its right elbow, stopping just before right hand trapping All Might. Percy turned to where the ice originated from and saw a white and red haired kid with a slight burn on his left eye wearing a white shirt and pants while also wearing a special kind of backpack he guessed. He also had the entire left side of his body frozen for some reason but that didn't matter now
"These two of your classmates Izuku?'' Percy asked Midoriya, who nodded as he explained "Yeah the blonde one is Katsuki Bakugo. He sweats nitroglycerin from his palms and uses them to create explosions. The other one is Shoto Todoroki. He can use both ice and fire with overwhelming force."
"One of your poorly trained thugs said you came here because you think you can kill All Might" Todoroki stated. Thankfully All Might was able to get himself free as he pushed the hand out and flipped over the warps as he stood next to Todoroki. Suddenly a red headed teen landed in front of Shigaraki and swiped his arms at him only Shigaraki to dodge without issues. The teen pulled back to Bakugo's position and lamented "Man I didn't get a turn to shine". Percy looked at Midoriya for answers and the little guy was quick "Ejrio Kirishima, Hardening." Percy studied Kirishima's arms and sure enough they looked as hard as rocks.
"The Symbol of Peace will not be defeated by delinquents like you." Todoroki continued while Bakugo threatened to blow the specter brace off if he moved. Percy however didn't feel relieved were six of them on one side and only Shigaraki was able to walk freely. So why did Shigaraki look so bored? As if he had expected this to happen. He took one look at All Might and clearly they were on the same wavelength."Kurugiri, how could you let this brat get the best of you" which made Bakugo smile.
"You got careless you dumb villain" Bakugo mocked the specter as he talked about the brace that led to him theorizing that an actual body exists. Shigaraki then went on a rant on how the teens barely had a scratch on them while they captured his two biggest men. Percy however realized that he was stalling for just enough time for Nomu to regenerate. But it was too late as the monstrosity willed itself out of the warps as it stood on one leg flailing its right hand and leg before they regenerated completely to everyone but Percy and All Might's shock.
"How?" Kirishima asked. "That thing had the ability to regenerate from any wound. Di Immortales I cut his entire left side and pushed it to the bottom of that lake." Percy remarked. "Correct now Nomu lets get our gate back." Nomu then charged directly at Bakugo too fast for anyone to see other than Percy and All Might. And Percy was a lot closer. Just before Nomu reached them Percy willed powerful gusts to push the four teens back and prepared himself for the hardest blow he had to take as the monster punched him creating a massive shockwave pushing him hard towards a gate.
Midoriya's POV
"KACCHAN!" Midoriya yelled out in horror seeing Nomu holding Kurugiri. Only to notice him right next to him. As were Kirishima and Todoroki."What happened? How did you get over here" Kirishima asked. Todoroki checks the impacted area and gasped seeing a figure behind the smoke believing it to be All Might "Isn't it obvious?! All Might pushed us out of the way."
"Actually, I can't take credit for that Todoroki-shounen" said a voice behind them. The four turned around and are stunned as All Might stood behind them. Midoriya did a quick headcount and realized the figure behind the smoke was no doubt Percy. The smoke cleared and the black haired teen was still standing much to everyone's surprise but was breathing heavily as he crossed his arms. "He pushed us out of the way but how?" Kirishima asked.
All Might sighed as he realized he was cutting it a bit too close but they deserved an explanation. "When Nomu moved Percy and I saw it coming. And apparently he can create wind gusts which he can use how he wishes" All Might answered.
Shigaraki laughed. "Wow All Might what happened there? I thought you would've saved them." All Might gritted his teeth as he stepped forward. "These are kids and you didn't hold back?" he asked angrily.
Shigaraki waved his hands around "Oh please I didn't have much choice. Besides these kids are no angels. That plain kid over there tried to kill me with a maxed out punch. What kind of hero does something like that? You think you can do whatever you want and say it's for the sake of others. Well you know something All Might. That pisses me off. Why do people get to decide that some acts are heroic and others villainous? Casting judgement based on prejudices. You're nothing more than a government tool that uses violence to solve his problems and violence always breeds violence. I'll make sure the world understands that when you're dead."
All Might was about to respond when the ground started to shake. Midoriya, Bakugo, Todoroki, and Kirshima all held onto him as they tried to figure out what's causing the earthquake. Then Midoriya took one look at Percy and noticed his anger. His eyes had turned a darker shade of green as he moved forward. "Is that why you attacked this place? Why you decided to terrorize a group of teenagers out with their teachers? Is that why you separated them into different areas just to ambush them? Is that why you dislocated both of a man's elbows and smashed his face into the ground leaving him laying in a pool of blood? In front of his own students? Is that why one of your cronies took a student hostage and threatened two girls to choose between their lives or his?" Percy asked rasing his voice with every question as the ground shook harder. For the students and All Might it was momentarily. But Shigaraki had to hold on to Nomu for dear life as the ground was unstable.
All Might POV
'That's three different elements now. It's possible it is him after all. But right now, I have about a minute left in this form. I better make this count.' He lets go of the teenagers as he closes the distance. But Percy wasn't done "You're a monster in human clothing Shigaraki. You put these students through a traumatic experience and I will make you pay!" Percy yells out as he lifts his right arm. Thinking they were going to see a watery creation, Shigaraki yelled out as a large stream of fire almost scorched him.
Everyone looked at Percy in shock 'It really is him. But how is he here?' Percy takes a deep breath and looks at All Might who stares back at him. The two nod before as they decide to team up.
Mt Olympus. A week after the Battle of Manhattan
Hestia tended to the hearth as she normally did everyday when all of a sudden she felt the blessing given to Percy activate. She then summoned the entire council an emergency notice and teleported back to Camp Half Blood to grab four different people and watch.
Hermes, Athena, and Poseidon arrived first and took their seats, since if Hestia called it she had to have had a notice about Percy. Zeus, Hera, Artemis, and Hepheastus soon followed and took their seats accordingly. Finally, Ares, Apollo, and Dionysus arrived and took their seats. As soon as everyone arrived Hestia appeared with Annabeth, Thalia, Grover, and Tyson.
"Why did you call us Hestia?" Zeus asked politely as he never once lost his temper while talking to his sister and this is the happiest she has been in a long time. Hestia had a watery smile as she answered "I felt the blessing activate. I know Poseidon did as well as Athena and Hermes. But something amazing is about to happen. Annabeth, do you still have it?" Everyone realized what she had meant of course, that Perseus was awake. But for her to call a meeting just for that wasn't her style. Annabeth nodded as she grabbed the ball point pen and uncapped it revealing Riptide. She had spent many nights crying herself to sleep in the hopes that Percy was awake and safe and now he was.
Hestia grabbed the blade and laid on the hearth as it displayed an image of what was occurring at the moment wherever Perseus was. When the image had cleared everyone gasped. They saw Percy stand next to a muscular man in a white shirt while staring at a purple brain monster with a beak, somehow the monster was as big as Tyson. There was also a specter and a turquoise haired creep who looked smug. Behind Percy were four teenagers at least 13 years old. But one look at Percy and everyone was shocked. He was angry and he was going to make someone pay.
Poseidon took one look at his son and shook his head. "Whoever brought about that expression upon my son, I wish them the best of luck." Athena questioned the Sea God "Is that it? The best of luck?" She asked "Of course. That look means, you have royally pissed me off to the point that I will destroy you."
Annabeth couldn't believe what she was seeing "What happened? I mean we've been through so much but the only time that I've seen him this angry was when Ethan betrayed him."
"I see you're about to enjoy the festivities" The Primordial of Time returned with a much more composed appearance. He stood next to the hearth and waved his hand rewinding the image ahead to a different frame to where the creep had made his stance clear. Chronos then began to relay his findings"Allow me to fill in the blanks with what I've discovered so far. You see the world Perseus is currently in is filled with people who have superpowers, or quirks. Around 80% of the world population have a quirk. So kids there have always dreamed about becoming the best hero. In this current timeline the man next to Percy is named All Might the best hero in the world. He had been putting his life on the line saving millions of lives while defeating countless enemies all with a smile on his face to reassure the people around him. He's popular in every single country but he had returned to Japan in order to find a successor and is now teaching at University Academia, a school whose main focus is to produce future heroes out of the many applicants with quirks."
"Seriously a school for heroes? What was Camp Half Blood then?" Thalia asked, feeling a bit disrespected. Chronos shook his head as he explained "What University Academia or UA focus on is not just combat training. They also focus on rescue training as well as conduct actual classes with math, english, science, and if need be support. Also those who apply to UA are then auditioned in a scenario where they have to eliminate as many enemies as possible but also try to rescue as many people as possible. Anyways back on topic. The kids here," Chronos zooms in on several group of teenagers, some of them were calm but others were horrified "were on a trip to conduct some rescue training when a bunch of thugs led by this man," Chronos then zooms in on a turquoise haired red eyed lithe man with hands all over his body and arms, making Aphrodite feel ill, "attacked them. The teachers available did their best but the kids were scattered around the building. Also the thing Percy is facing right now is a Nomu. From what I've gathered so far, it's a bioengineered human being being injected with a random quirk but this one was meant to defeat All Might, with shock absorption and regeneration as its quirks"
Athena stops Chronos for a moment, "How in Chaos's name was that thing bioengineered?" Chronos shakes his head as he doesn't want to answer that, feeling already disgusted about that, However Annabeth follows up, "Well why is Percy fighting it?" "Because the leader of the villains had the gall to ask what warrants actions to be heroic or villainous. And Percy had this to say." Chronos answers as he pulls the image back to where Percy created an earthquake with his powers and asked scathing question after question with each step he took. Poseidon was cheering loudly as was Grover, Tyson, Thalia, and Artemis after the two girls having to choose between their lives or their friend's question. Annabeth smiles as the old Percy is still there fighting the good fight and sheds a small tear.
Chronos brought the image back up to speed and played it "Now watch as Percy creates his own quirk using the blessings given to him and his powers"
USJ
Percy calmly took a breath and focused on all four elements he was able to use today and as he did his eyes began to glow as wind, water, earth, and fire surrounded him. He then covered his fists with all the elements and gave All Might a smile, who responded with one of his own. Once Shigaraki was on the move he and All Might moved to intercept knowing Nomu would jump in his master's stead. Once the three forces collided, Percy and All Might began to trade fast and heavy blows with the creature sending massive shockwaves that were felt all over the building.
Midoriya looked on in shock. Todoroki couldn't keep his eyes off. Bakugo was stunned. And Kirishima was trying to stay still. Even the students at the entrance were watching though their view was obstructed.
Shigaraki began taunting them "Didn't I tell you that he had shock absorption?! It's pointless"
Percy responded with a deeper voice "I DON'T CARE!" effectively shutting him up as the two kept punching Nomu over and over again as hard as they could. But this time something changed,
All Might yelled out "You said his quirk was shock ABSORPTION, not NULLIFICATION!" Percy then completed the line of thought "Which means there's a limit to how much you can take, big man" as Nomu was getting pushed back over and over and his punches while striking both men, only seemed to endear them to punch even harder.
"So, you were made to fight me big guy? If you were really designed to take me on at full power" All Might continued. Percy again followed it up "Then we'll just have to go beyond that power and force you to surrender" As they said that the speed of Percy and All Might's punches became so fast that Nomu couldn't block.
Suddenly Percy cocked back and threw a haymaker onto the creature's head sending it flying backwards. The two heroes stood side by side and ran after it, not letting up whatsoever. Midoriya and Bakugo watched as a guy the met just today was matching All Might, the hero they both worshipped and wanted to emulate, stride by stride while using his own powers.
Nomu however wouldn't quit as it rolled up and charged back in only for All Might to knock it into the sky. Percy jumped after it and began to yell out "A REAL HERO" pausing only to block Nomu's desperate counter before using his legs to propel the beast off of him launching him towards All Might who finishes the thought process "will always find a way for justice to be served." All Might then grabbed Nomu's leg and swung as hard as he could before throwing him to Percy. Percy then sat the creature on his shoulders before driving it hard to the ground with a massive powerbomb which unleashed a large dust storm.
Percy began charging up his right hand with the elements under his control while All Might landed next to him "Now you may have heard this term before. But allow us to show you what it really means" All Might stated as his right fist started glowing. Together, the two hit Nomu with a combination of their abilities while crying out "Go Beyond PLUS ULTRA!" sending the beast skyrocketing out of the USJ and past the stratosphere.
OOOHHH BABY. That was rough. Now I know what you're going to say. Percy is not supposed to be anywhere near All Might. True. But he's being powered up exponentially with every element he had mastered and as a result, his strength skyrocketed. Also this is to set up Percy as the stepping stone Class 1-A will need that is a lot closer to their age than say someone like All Might. Percy is only a few years older than them and yet has much more experience than any of them. However no I won't do this over and over again. You'll see why in the next chapter
Next Time: Percy and All Might are out of energy and have to wait for backup or can they bluff Shigaraki to run?
