The Fox Of U.A
At the Final Valley we see two people fighting. One of the people is Uzumaki Naruto a young man with blonde hair and blue eyes in an orange jump suit but currently he's covered in a red cloak of some sort. The other person is Uchiha Sasuke, a boy with black hair and a blue shirt an white shorts with what looks like flames all over his face. These are the power of the Kyuubi and the curse mark respectivly. "Sasuke I'll bring you back even if i have to break every bone in your body!" NAruto yells. "Let's see you try dobe you know I'm stronger than you." Sasuke taunts. They begin to fight throwing punches and kicks. Naruto goes for a gut punch but Sasuke uses his right hand to block and retaliates with a kick to the stomach. Naruto spits up blood but hits Sasuke in the stomach then they jump away from each other. "I'll finish you with one move Naruto!" Sasuke screams "I'll bring you back no matter what!" Naruto yells back. Sasuke then starts charging up his chidori and charges up a low powered rasengan. "NARUTO!" "SASUKE!" Sasuke goes for a killing blow while Naruto goes for his stomach. Then Naruto changes his attack to hit Sasuke in the face slamming him into the mountain knocking Sasuke while Naruto gets stabbed in the left lung by Sasuke barely missing Naruto's heart. But little did they know that the leader od the Akatsuki was watch and wanting to capture the Kyuubi but luckily Kakashi gets there in time to stop him from capturing Naruto. Kakashi uses his Sharingans power Kamui to try and save Naruto but the leader of the Akatsuki uses his Kamui trying to stop Kakashi. It resulted in them creating a portal to another world that sucked Naruto in.
In the MHA world
In the world of MHA in the city of Musutafu the day is going normally until a portal open up and a blonde child falls out landing on the ground harshly. "OH MY GOD! that child just fell out of the portal!" yells a random civilian luckily Toshinori Yagi was close by and saw the child fall out of the portal. As he transforms into his muscular form. "Have no fear. I am here!" Toshinori notices the hole in the childs chest and thinks 'My god i didn't think it was this bad.' "If you excuse me I must get this child to the hospital!" All Might says as he flys away. As All Might flies away to the hospital to call Nezu. "Toshinori why are you calling?" asks Nezu. All Might responds "I was walking around Musutafa and a portal opened up and dropped a kid out. And he has a hole in his chest get Recovery GIrl ready!" yells All Might. "She'll be ready when you get here." Nezu responds calmly. "Alright." All Might says before flying faster.
Time skip Two minutes later
All Might arrives at the hospital with the boy and Recovery Girl grabs the boy and puts him on a stretcher. "Toshinori what happened to this child!?" Recovery Girl ask. " I don't know. All I know is that he fell out of a portal with those wounds." Toshinori says in his skinny form. Nezu raises an eyebrow at this but says nothing. Recovery Girl notices something and says something "Look at his wounds!" she says. "Huh?' Toshinori says. "His wounds are healing themselves." Recovery Girl responds. Nezu looks at the boy and says "He must have a powerful healing quirk." Toshinori just looks at him then the boy starts to stir and shoots up yelling "SASUKE!" Recovery girl touches his shoulder and says "It's ok child you're safe." Naruto looks at her and says "Where am I? Naruto then looks around and notices he's in a hospital. "I failed." naruto says sadly. Recovery Girl looks at him confused "What do you mean and whats your name?" Naruto looks at her and responds " My name is Uzumaki Naruto and what I mean is that I failed to keep my promise to my friend." "What promise?" Nezu responds. Naruto looks at nezu and responds "My promise to bring back my team mate to the village." Naruto continues "I never break my promises its my nindo my ninja way. And now that I've broke my code I don't know what to do." Nezu rubs his chin and asks "What's your quirk young man?' NAruto looks confused "what's a quirk?" The three heroes look stunned the All Might speaks up "How do you not know what a quirk is Young Uzumaki?" Naruto looks at All Might "I've never heard of quirks but I know of chakra its what helps me do my ninja moves." Naruto then continues " I've never heard or seen any of you are we close to Konoha?" Nezu steps up "No young man we haven't heard of Konoha. We are in Musutafu" Nezu says calmly. Narutos eyes glaze over and he gets pulled into his mindscape.
In the seal. "What have you done boy!" the Kyuubi yells at Naruto. "I don't know baka fox I don't know how we got here." The Kyuubi growls out "We are most likely in a different dimension because of your love spat with the Uchiha." Naruto blinks "WAIT we're in a different dimension is there a way back?" "Probobly not boy." the fox says back calmy. "I recommend making the best of what you have here. Also your body is changing aind is absorbing my chakra a lot faster then it should. Most likely you'll absorbs me and become the new Kyuubi."
