One day long ago in Quig Quig, China, a luminescent baby was born with a unique power. Then, as time passed, the similar phenomena happened all over the world, and soon the majority of the population had obtained superhuman powers such as ice, echo location, super speed or super strength. These abilities were known as "Quirks". Due to that, people were able to pursue heroism as a profession witch led to many great hero's to look up to. Such as Gran Torino, Nana Shimura, Hawks, Fat Gum, Midnight, Eraserhead and Endeavor (NO WAIT! Scratch those two. They are horrible hero's and terrible people. The fact that they are still pro hero's is truly amazing). But the greatest pro hero of all is Toshinori Yagi or as he is know by his hero name, All Might. The No1 Pro hero. To say All Might was a hero would be a understatement, he is a savior. At one point he saved a thousand people from a burning building. Little did anyone know, All Might's Quirk was passed down from another person. Toshinori's hero persona derives much from American superhero stereotypes, in which they are colorful and have a lot of dramatic flairs. Always sporting a giant smile, he usually shows off a bright, can-do attitude that borders on being obnoxious. He also tends to be extremely friendly and amicable, due to his popularity and years in the spotlight. However, when he reverts to being sick and scrawny (as a result of a previous battle), he tends to be less energetic due to his constant blood-spitting. Additionally, he tries not to draw much attention to himself while in his true form, always afraid that others might learn of his current state of health. He is the eighth user of the One For All Quirk. With how great All Might is it would make since that he would have a lot of fans, one of his biggest fans was a boy named Izuku Midoriya. Though born without a Quirk, Izuku always dreamed of becoming a hero. Izuku is a very timid, reserved, and polite boy, frequently overreacting to abnormal situations with exaggerated expressions. Due to years of being looked down by one of the worst human beings known to anime Katsuki Bakugo (Katsuki's friends even comment that he may have gone too far bullying Izuku in reference of Katsuki telling Izuku to take a leap off of the school's roof) of lacking a Quirk, he is initially portrayed as insecure, tearful, and non-expressive. These traits are especially present around Katsuki, who also constantly harangued him for his aspirations to become a hero but it never stopped Izuku from hoping and trying. One day Izuku even got to meet All Might and asked possibly one of the most important questions in Japan, "Can you be a hero without a quirk"? This question actually stunned All Might for a bit. All Might honestly didn't know what to think at first but soon realized that a slime villain he had just captured had managed to escape into the streets of Japan and what made it worse was he took a hostage, but it wasn't so bad because the hostage was Bakugo. All Might tried to stop it and save the hostage but his time in his hero form ran out. As pro hero's tried to stop the slime villain and save Bakugo, Izuku ran to the battle to try and save Bakugo. Izuku didn't know why he did that but he knew he couldn't just leave Bakugo yo die. But as Izuku tried to save him a loud bang shook the city. Everyone from pro hero's to reporters stopped what they were doing, even the villain froze up. It had sounded like something had ripped a hole in the sky. Izuku looked up and saw a little black dot in the sky quickly heading towards the ground, right where they were standing! Izuku looked up in horror as what now looked like a jet coming down like a mentor. As the jet got closer and closer All Might used what strength he had left to go back to his muscular form and quickly got Izuku out of the way of the incoming jet while Bakugo was still trapping in the slime villain. Then without a warning the jet crashed into the streets and sounded like lightning strike. Hero's and the slime villain were sent flying from the impact of the crash. After a few seconds the slime villain approached the jet hoping he could find some people with powerful quirks. But there were no people with quirk's in there, instead there were hero's from another dimension, their earths mightiest hero's, The Avengers.

Avengers point of view.

Iron Man, Captain America, Bruce Banner, Thor, Spider-Man, War Machine and Ant Man looked outside the jet and saw nothing but smoke, fire and a destruction around the area.

"Oh crap I must have sent us to a apocalypses world". Tony said as he looked outside. Scott was just looking outside.

Rhodey looked outside "God don't tell me we are in Attack on Titan".

"So does anyone have the slightest clue on where we are"? Scott asked looking at his friends. Peter looked out the window and his eyes widened and his mouth dropped.

"HOLY-" Peter was cut off when a slime monster started attacking the jet. Everyone jumped in surprise and alarm. Thor grabbed his hammer and looked at the monster.

"Aye ye slime monster, you just picked the wrong jet to mess with".  Without a seconds hesitation Thor threw his hammer at the creature and attacked it. Thor then shot lightning at the creature. Tony looked at Thor as he flew out of the jet and attacked the creature.

"THOR WAIT"!!! Tony said as Thor flew out of the jet and attacked the creature. With the crack of Thor's hammer the slime creature was sent flying across the street. For a moment Tony could have sworn he saw a blonde haired boy come out of the creature. Tony Stark rubbed his eyes as the creature started to reform itself. Peter looked at Tony.

"M-M-M-Mr Stark! What do we do"? He asked panicked. Tony scratched his chin and thought for a minute. After a few seconds his eyes widened and he snapped his fingers.

"I got it! Ok here's what we are going to do. Banner you stay in here and be out look out and stay here unless we need you. Rhodey, Lang and Parker you evacuate the area and help anyone who might be trapped. Cap, Thor and I will handle the slime monster. Everyone got it, got it. Wait one last thing. I've been wanting to use this for weeks". Tony opened a compartment on his armor and pulled out seven pills. Rhodey raised a eyebrow.

"Tony? Why do you have seven pills with you and in a convent part in your armor"? Rhodey asked confused by this.

"Well I figured if we came across any alien species that didn't understand human language I should have something that would make it easier for us to understand them and them to understand us. Took me and Banner weeks to complete this and get it right". Tony said giving each Avenger a pill. Captain America looked at Tony confused

"Wait so this allows us to understand people too? How does this pill even work Tony"? Steve asked Tony. Tony just looked at him.

"Honestly...............I couldn't explain it if I tried" Tony told him.

"So I guess, AVENGERS ASSEMBLE"! Tony shouted. Captain America and Iron Man attacked the slime monster as Rhodey, Scott and Parker evacuated the area. Peter grabbed a green haired boy and Rhodey got a angry blonde boy who kept punching and shouting at Rhode to let him go. Once the hero's got the boys away they went to help Captain America, Thor and Iron Man fight the slime creature. Iron man fired his repulser blasts at it, Thor smashed it with his hammer, Rhodey fired rockets at it, Spider Man used net webbings on it and Ant Man constantly punched the creature. The creature threw its fists left and right at the Avengers but the Avengers had the upper hand and soon managed to pinned it down. As Spider Man webbed it up Iron Man received a call from Banner.

Banner: Tony. We have a slight problem

Tony: How slight?

Then this happened

The Avengers stood in shock and looked to see who it was who gave such a powerful punch. They looked in front of them and saw this man

Banner: This slightly.
