As Izuku slowly walked towards Bakugou, the flame in hand seemingly glowing brighter, Bakugou could only watch. All he could feel was confusion and anger. 

                  'What the fuck is going on?!' Bakugou thought. His mind was racing everywhere. 'I thought that shitty Deku was quirkless?! It was confirmed. This is impossible!' Bakugou proceeded to stand back up with a slight wobble. Luckily the blast only pierced his clothes and his skin, but it had still caused a fair bit of bleeding. He clutched his stomach and looked at Izuku. For a split second, he looked like a completely different person. Most of his face was covered with a massive scar, which appeared to look like very dark skin (See picture above). His hand was still holding the mysterious orange energy that had hit him in the first place. Once Bakugou realized that he was intending to harm him. He got in a fighting stance while his palms began popping small explosions. Seeing this only made Izuku laugh.

                 "Is that all you can do?" He asked in a deeper, serious voice. . "You are scum, not worthy of being the tenth holder of All Might's power." He continued. "I am." He raised his hand, still glowing, and aimed it at Bakugou, who did the same with his hand. 

                  "You've gotta be kidding me! NOW YOU HAVE A QUIRK?! HAVE YOU BEEN HIDING IT FROM ME?!" Bakugou demanded in anger. He raised his arm as Izuku did the same. They were about to fire until they all heard a loud voice. 

                   "STOP! BOTH OF YOU CHILDREN!"

Hearing this, the two teenagers looked over to see two very familiar heroes. All Might... the number one hero,  and Hive Mind... the number sixteen hero, both in costume. 

                   "FOR I AM HERE!"

                    'Mom... Dad...' Izuku thought. Seeing the two in costume made him snap out of it. The fire in his palm faded away as well as his scar, rescinding to only a few spots on the side of his face. Bakugou sighed in relief, knowing this fight to be over. Izuku looked down at his hands in confusion before dropping to the floor and starting to cry. All Might and Hive Mind looked at each other with guilty faces before moving towards the boys. 

                   'Oh no...' All Might thought. 'I got up extra early to meet with young Bakugou, and my wife decided to tag along to get a first impression on his abilities... but why was Izu here..? What was that flame... and why was he acting so... villainous..? Don't tell me...' They were now within  two feet of Izuku who was still on the ground and Bakugou who tried playing it cool despite being visibly nervous. 

                   "Ah... Hello young Bakugou! I see you're here for that thing!" All Might said while smiling. "And you... young Midoriya was it? What're you doing here? Shouldn't you still be asleep?" Izuku tried collecting himself before looking up at his father, with eyes red from the breakdown he just had.

                   "D... Dad...M- Mom..." All Might froze. 

                   'Shit! He knows.' He thought while looking at Hive Mind, who had the same expression as him, both visibly distressed. 

                    "Please... son... Allow us to explain ourselves..." Hive Mind said shakily. She became heartbroken once she saw her son. She knew there was a reason he was here, and not a very good one.

                    "No... I- I already know everything... " Izuku said in a low tone. Their stomachs sank. He then turned towards his father. "I heard the conversation you and Kaachan had yesterday, All Might, or should I say dad?" All Might felt steam, and soon transformed into his true skinny form.

                    "Izu... I'm sorry... I didn't mean to hurt your feelings." All Might pleaded with his son. "I only said you couldn't be a hero because it was too dangerous! I didn't want you getting hurt... or even killed!" Izuku just looked at him trembling.

                     "No... you were right, it would have been dangerous." Izuku said, his eyes suddenly brimming with hope. "But now I can! I just got my quirk! I can be a hero! I can inherit your power! I can be the number one her-"

                     "I'm sorry but no." Izuku stopped rambling when he heard his father speak. 

                     "W-What?"

                     "I said no Izu, I saw how you were acting when you were using it. You were being too aggressive. Too crazy. I can't just allow you to inherit my quirk just because you're my son." Yagi said in the same tone from the roof. "Plus not to mention that you just harmed your friend, your only friend! What did he ever do to you Izu, you can't just attack him because of your jealousy and flashy quirk!" Yagi said now scolding Izuku, while Bakugou was being tended by Inko. Once seeing Izuku's reaction, Yagi immediately regretted digging that deep. As Izuku began crying again. Everyone's eyes widened when they saw Izuku's scar. It was expanding... all over his face. Yagi tried to calm him down only to be pushed away. Hive Mind ran over to him to make her attempt, but was met with Izuku running away.

                       "I'm sorry Izu. I didn't mean to say it like that!" All Might apologetically. Now running after him with Bakugou and Hive Mind after him. He then turned around, where the dark scars had now completely spread to his face. The three stopped and looked at Izuku, who still seemed to be crying, but his aura was emanating pure anger. 

                        "DON'T FOLLOW ME!" He shouted, his hand glowing orange again as he flung what looked like a fireball at the boardwalk. In less than a second a large portion of it collapsed, leaving the three separated from Izuku, who continued running until he was out of sight. Hive Mind was about to go after him, but was stopped by All Might.

                        "He just needs time to calm down, then we can handle it from there." He said turning towards Bakugou. "Are you all right, my boy?" He asked, receiving a nod. "In that case, our training will continue despite this setback." All Might said, who just returned to his buff form. Bakugou only smirked. 

                          'You got it All Might.' Bakugou said pridefully. He then realized that the old man who was at the pier as well had seen and heard everything. He looked towards the edge of it only to see no one there. 'What the hell..? Where'd he go?!' Bakugou questioned. 

                          "Is something wrong Bakugou?" Hive Mind asked, only to be denied. He didn't want them worrying about a potential witness and just assumed it was just his imagination. 

???

                   'I can't believe this. That boy possesses the flame of wrath! One of the rarest flames not seen since the days of Segundo! I must find him, he will be a fine addition to the academy.'

Meanwhile with Izuku...

                'Why why why why' was all the boy thought. By the time he stopped running, he realized he was at a park. He sat down on the bench and started sobbing again while looking down at his hands. 'What was... that power..?' He thought. 'Was it a quirk... did I get a quirk?' 

                "I am afraid things are far more complex than that, young man." An unfamiliar voice said. Izuku looked over to see an old man approaching him. He definitely looked very out of place, much like a typical tourist. He was wearing a blue Hawaiian shirt and a large wide-brimmed brown hat. Even though he was a complete stranger, Izuku felt a sense of comfort and safety from the man. He then sat down next to him. 

                "W-What do you mean sir? It must be a quirk. Nothing else can explain it!" Izuku said, only for the man to laugh heartily.

                "Oh... young man, how little you know." The man said, while also stretching out his hand. "I'm Timoteo, pleased to meet you." He smiled. Izuku took the hand and shook it. 

               "I'm Izuku Midoriya. Pleased to meet you as well." He let go and both their arms returned. Timoteo took this as a sign to continue. 'Timoteo... where have I heard that name before..?' Izuku thought, trying to rack his brain for the answer. Somehow the man could tell what he was thinking. 

               "You may have heard of me before, young Midoriya. although I am better known for my title, the Vongola Nono." As soon as the man said those words, Izuku's eyes lit up.

               "Are you being serious? The Vongola Nono? Of the Vongola Academy, the top hero school in Europe?!" Izuku kept questioning the man until he began full on mumbling. Timoteo knew he had to stop it. 

               "Stop! *Cough cough* Yes I am in fact the boss of the school you speak of... and that's why I am here now." Izuku's eyes widened. "For you see, I saw you on the boardwalk, saw you demonstrate that power of yours... and as I said earlier, it's not a quirk, but a flame, a very rare and powerful one at that." Izuku was now confused, and told the man so. He then explained to the boy the secret of the Flames, or the Dying Will Flames of the Sky, a secret manifestation of refined energy generated from one's own life force. Due to natural evolution, the only people capable of using them were those from the old age; the quirkless. He then told Izuku about the fact that he possessed a very powerful variant called the Flame of Wrath, only seen once in the Vongola Segundo centuries ago. Izuku's eyes lit up once more with excitement. He couldn't believe it... He could have power. Suddenly the man frowned. 

                "However... there is one major downside to your power specifically." Izuku quieted down and he continued to speak. "Some flames can be amplified or hindered by the emotions of the user. As the name implies, your flame feeds off your rage. In order to use it regularly, you must release all your rage and lose your true self. However with training, your mind will handle it better as time goes on, but you will never be the boy you once were." He said, leaving Izuku in a shocked state. "I wouldn't blame you if you're not up to it, but it is the only-" 

              "I'll do it." Izuku said suddenly. Timoteo's eyes widened to the sudden decision he made. "Everyone told me I couldn't be a hero, if this is the only way, then I'll do it." Timoteo shook his head and smiled.

               "Very well, in that case you will need to transfer to the academy in Italy immediately." Izuku nodded. "I'll let you decide on whether or not you tell your parents, your choice on that." He shook his head sideways.

               "I'll tell them in the future, but not now, not for a while." Izuku said, Timoteo only shook his head.

               "Very well. From this moment forward, Izuku Midoriya is now dead to the world, and from his ashes rises a true hero the world needs. What shall you be known as now, to represent your newfound resolve and ambition? He asked. Izuku's excited look had now faded into an angry look, he looked down at his hand while he rose and it began to glow orange once again, brighter than ever. 

"Xanxus, the true tenth holder on One For All"

Time-skip: Izuku Midoriya, now reborn as Xanxus, has left Japan for Italy soon after. Shortly after joining the Vongola academy, he meets Superbi Squalo , who becomes his loyal subordinate as well as the Strategy Captain of the Varia. The Varia is the Vongola's secret Villain Assassination Squad founded by Xanxus. The Italian Laws are different from Japan, as killing Villains was legal, but still looked down upon. More members join and they have made a name for themselves on the underground. Over the next ten months Xanxus has trained both his flame and his body for his ambitions. He was given special support gear in the form or two handguns that can shoot his flame in a much more condensed and powerful form. As he trained, he became more and more villainous, losing all sense of compassion and respect (Except for Timoteo). Upon hearing that All Might has begun teaching at UA, Xanxus decides the time is now, and the Varia transfers to UA with little issue due to their equal level of prestige.)

A/N: 

Xanxus is sounded like "Zenzus"

Inko Midoriya is Hive Mind, the Psi Hero

Picture isn't mine.

Timoteo, Vongola Nono:

That's all. Until next time.
