Chapter 1: The Rise Of Deku

(Opening A/N: Okay this is my first My Hero Academia crossover with Marvel Vs Capcom, so please be nice. Here's how this goes, shortly after Thanos has stolen Gohadoken from Ryu and has taken out both Jedah and Death, both immortals have opened up another dimension and before their demise by the hand of Thanos, they prophesied that a boy by the name of Izuku Midoriya is going to be the downfall of Thanos, and it's up to both the groups of both universes to help young Izuku in able to help him reach the superhero status and become the symbol of peace between the three realms, but in able to reach his true potential, he'll have to join forces with other heroes from the other dimensions in able to defeat this new threat known as Thanos, friendships will be forged and tested, lives will be lost, and only one will stand true. This story will start off as a T rating but might be bumped to an M rating in case I intend to add some lemons, as for the disclaimers, I don't own Marvel Vs Capcom for they are owned by their rightful owners along with all of the characters mentioned, and as for My Hero Academia, that is owned by Horikoshi Kouhei along with Shonen Jump and Funimation. So without further ado, here's the first chapter)

[After Ryu's defeat…]

Izuku watched as his mentor who taught him to use martial arts to harness the power of one for all was defeated by the titan known as Thanos.

"So it has finally come down to this, the fate of three worlds rest in the hands of a young boy who can't even control his powers." Thanos said as he let out a sinister cackle.

Izuku was just on the verge of tears seeing a hero who sacrificed himself and trained him in martial arts was laying on the ground helpless, but thanks to Ryu's Training, Izuku began to feel the strength to take on Thanos.

"Thanos, you're going to pay for what you did!" Izuku called out as a white aura began to envelop around Izuku's body as he began to mimic the actions of Ryu as if Ryu's fighting spirit began to possess Izuku's body.

Izuku then began to swing his arms in a circular motion as he began to focus the energy that was building up within him.

"You got this...Izuku." Ryu said weakly, Izuku then charged at Thanos as he had a powerful punch waiting for the titan as he combined Ryu's attack with a Detroit Smash.

"Shoryuken!" Izuku shouted as he connected a right hook with Thanos sending him crashing to the ground.

Izuku then noticed that his arm wasn't destroyed, and it turned out that Stark had just made something that could give Izuku the edge over Thanos, The Smash Gauntlet which also contained the power Infinity Stone.

Thanos got up from the floor and rubbed his jaw, he knew that Izuku was going to .

"Interesting...I would say that has given you a reprieve. But not for long, I'll be back and when I have returned...I'll paint the starways with your blood." He said before exiting out of the area via a stolen teleporter.

Once Thanos was gone, Izuku raced over to Ryu and checked his pulse, luckily he had a steady pulse.

"Sensei?" Izuku asked, Ryu then placed a hand on Izuku's shoulder congratulating the young boy.

"Good work Izuku." Ryu said passing out.

A couple of hours later Izuku was standing next to his master who was in a deep sleep.

Captain Marvel stood next to him and placed a comforting hand on his shoulder.

"You okay?" she asked, Izuku nodded even though he was worried about his sensei.

"I will be, once Thanos is down, let alone we bring him to justice." Izuku said, but the only justice he'd see is elimination and can't live any longer.

Just then, the duo was joined by both Iron Fist and Ken Masters, friend to Ryu.

"So you must be the one known as Deku, I'm Iron Fist." Iron Fist said, but before we get to anything further, allow me to take a step back to how this whole situation came to be…

[Rewind to when Thanos used Satsui No Hado on Jedah and Death…]

Thanos has just unleashed the Satsui No Hado on both Jedah and Death, but before they met their demise, the two opened a new dimension, this time it was a different timeline from either the Dark Kingdom, Earth, and Asgard.

"Heed our warning Thanos, your demise will come by the hands of young boy who goes the name Izuku Midoriya, and he shall be the one to protect all the dimensions." Death said as she collapses and turns into dust with Lord Jedah.

The news of both Death and Jedah had just reached everyone, and it seemed that Dr. Strange was the first to find out about Izuku and he needed to find out how he can be able to stop Thanos.

So, Dr. Strange and Chun-Li decided to see if they can find the one that Jedah and Death prophet sized to Thanos, so they went to the new dimension where Izuku Midoriya lives, as they began to ask around about Izuku Midoriya, and there was one place where the duo can find him, U.A. an academy school who specializes in teaching future heroes.

[U.A. Exterior...]

As soon as Dr. Strange and Chun-Li found the school, they were met by All Might.

"Can I help you two?" All Might asked, and Dr. Strange told him that he along with Chun-Li were both looking for Izuku, and this seems to be the luck that All Might was looking for, he could be able to have these new heroes help Izuku train his abilities and handle One For All.

"We were wondering if we could be able to meet with Izuku Midoriya." Chun-Li said, and All Might signalled both heroes to follow him into the teacher's lounge, where they waited for him, All Might made the announcement over the P.A.

"Izuku Midoriya, please report to the teacher's lounge, Izuku Midoriya please report to the teacher's lounge, that is all."

Just then Izuku enters the teacher's lounge as he saw All Might with two strange heroes he's never met.

"You wanted to see me All Might?" Izuku asked, and All Might signalled Izuku to take a seat, but it seems that the school day was just about to end, so Izuku sat in a seat as All Might had a proposition for the young hero in training.

"Yes it seems that these fellow heroes from another dimension need your help in taking down a mighty villain, a rogue titan called Thanos. Maybe you can have these fellow heroes help you in controlling one for all." All Might said, and Izuku accepted the offer of helping these new heroes beat the mighty titan Thanos.

Just then, the final bell rang signalling all the students that classes have ended, and All Might offered Izuku to take Dr Strange and Chun-Li to Izuku's place and see if Izuku's mom would be supportive of Izuku in able to fight along with these new heroes.

So Izuku headed back to the classroom as he grabbed all of his stuff and he had both Dr. Strange and Chun-Li follow him to his house, but it seems that there was one person who happened to have a score to settle with Izuku.

"You're going down Deku!" Bakugou screamed as he charged right at Izuku, but Dr. Strange used stasis magic on him before he had a chance to harm Izuku.

"Come Midoriya, it's getting late." Dr. Strange said, and Izuku nodded as he lead the two heroes to his house.

[Izuku's house…]

"Mom, I'm home and I brought friends." Izuku called out to his mom as he took his shoes off along with Dr. Strange and Chun-Li doing the same.

"Who are your friends?" Inko asked, and she happens to be Izuku's mom, but as a sign of respect, Dr. Strange bowed to her and formerly introduced himself along with Chun-Li.

"My name is Dr. Stephen Strange, and this is my associate Chun-Li. We came here to see if we can recruit your son into helping us with a certain matter that needs his attention." Dr. Strange said, and she then offered the two inside and made them some tea.

As soon as everyone was all situated with, it seemed that her little boy wanted to become a hero like his role model All Might.

Izuku began to draw out the sorcerer supreme, but when Dr. Strange knew what Izuku was doing, he decided to give the young boy a hand.

"Allow me, young Midoriya." Dr. Strange insisted as he used a spell and made a more artistic image of himself along with some facts, strengths, weaknesses, along with an origin of how he became a sorcerer supreme.

He even added one on Chun-Li as well, and Izuku knew that he was going to need more notebooks since there were other heroes and heroines he was going to meet along the way.

"I can't believe that my little boy is becoming an actual hero, I mean all I can do is be supportive of him, I ask as a mother, please take real good care of my baby." Inko said as she had a saddened look on her face.

"We promise you, we'll take real good care of your son, along with giving him all the training he can get." Chun-Li said as she reassured Inko that he was going to be the greatest hero of all time.

Dr. Strange, Chun-Li, and Izuku all got together as they teleported to Avenger tower to meet up with the rest of the group.

But how will Deku react to these new heroes, and how will he defeat Thanos? Tune in next time for another awesome chapter…

[To Be Continued…]

(A/N: Okay here's the first chapter, don't worry, I'm not going to kill off Ryu since he's one of my favorites, and I'll be sure to add more Marvel and Capcom characters, I just wanted to keep it limited at first, but I'll be sure to bring in more soon, and to top it all off, this is an experiment with help from Autistic Grizzly, so I could care less if it flops. Feel free to leave a review, fave, follow, idea for a future chapter, etc. And until the next chapter, this is the master of chaos, the commander of the legion of corpses, BloodyDemon666 signing off!)
