Izuku felt himself floating in an endless space and could tell that he had been drained of his powers but he felt the familiar power of his dreams and began trying to move. It felt like months had passed before Izuku began being able to move freely. He watched as he went in a direction and saw a world where people were fighting it looked like the sports festival but something was off about it. He went towards it and felt himself fall through and he began exploring he saw the fight that was going on.
He saw that it was Todoroki versus Bakugo and assumed he was in the past but then noticed that they were fighting differently. Izuku noticed as a version of him appeared in the middle of the arena. Bakugo rushed him and was quickly grappled and countered with a knife at his throat.
Izuku stood shocked at what this universes Izuku was doing, but he knew he couldn't do anything. He then watched as a large scale fight broke out as Izuku murdered a civilian. That Izuku then proceeded to get into a fight with All-Might where they seemed to be equals.
Suddenly he felt a force pulling on him as he once more went to the void he had been in. He had no clue how long he had been drifting but he had come to the conclusion that he was drifting between dimensions.
He began to gain control over time he began drifting between dimensions and observing. He saw many different forms of himself all with their own unique quirks and personalities but he just wanted to get back to his dimension.
Several Years In The Void Pass
Izuku had become distant he had seen many dimensions where he was a villain and many where he was a hero. Then there were the dimensions that either were nothing but remains of a civilization, and still others where everything seemed fine just nobody had quirks.
Izuku had developed long hair in this time with the same tint of green as always. He had learned that he no longer had to drift but could walk between the dimensions.
He had heard whispers while between dimensions but could never find the source but for some reason today the whispers had turned to normal talking and he felt like he was close.
It didn't take long until suddenly there was a new dimensional portal and he ran straight for it. He went through and fell to his knees and looked around, he saw what looked to be a small chamber with many personalized thrones.
"We have been expecting you Izuku Midoriya. We are the council..." Izuku noticed as each throne developed a hooded figure. "We have all gone through the void between dimensions until we found this place. Here we have waited for someone else to wander here." The hooded figure who was talking lowered their hood.
Izuku's eyes widened as he beheld a face he knew all to well as it was his own. "We are all Izuku's who have had our abilities tested by the stranger who travelled time. Each one of us has either taken their power or learned to use a similar power."
"You have been pushed into the dimensional gap by your sudden loss of power to All For One. We all wish to help you but will not force it upon you. You may decline and we will show you the way back to your proper dimension." The identical Izuku walked down to him and let out a hand.
"If I accept what does this help include? It's been so long since I had left and I should get back fast." Izuku said getting up looking at his identical copy. "We will help by allowing you to develop some of our quirks and we will teach you what we know about our own quirks."
Izuku thought about it and smiled. "Well it would be better for me to return with powers so I can be helpful." The other Izuku chuckled as the chamber began to expand so that an arena opened. When the arena finished expanding the thrones began to empty as each Izuku jumped down to the Arena.
As Izuku went into the arena where he saw that there was a line to teach Izuku. "I only want to learn a few for now so I can hurry and return to help my friends. All For One is too big of a threat for me to be gone much longer."
The first Izuku stepped up, this Izuku seemed to be much more physically built than the others he also had several scars along his arms. "Fine but I will give you some heavy power. Just so you know in my universe All For One had the ability to take over people and transfer his essence. In my universe I had to defeat an All For One who had taken One For All and Taken over All-Might. I only have one quirk that I have mastered to the point of teleportation but that took many years of isolated training to pull off. We won't have the time to get you that far but I believe you will learn it in time."
Izuku smiled at the potential of the quirk he was about to learn how to use. "I am ready to learn." Izuku's long hair now about the length of his back began blowing behind him. Suddenly Izuku felt as a gust of wind hit him in the chest and sent him flying.
"Step number 1 be prepared for anything just because you can't see an attack doesn't mean you can't counter it." The bulky Izuku punched towards Izuku and Izuku tried to block but felt as his legs got knocked out from under him. "You have to be able to read your opponents movements so you can react faster than their attack comes out." The bulky Izuku then suddenly appeared next Izuku with lightning sparking across his body, he launched a punch into Izuku's chest that sent him flying.
Izuku landed and got to his feet and saw as the bulky Izuku smiled. "Also be prepared for the potential of an opponent holding back against you. I just won't hold back to much." Suddenly a lightning bolt struck Izuku bringing him to his knees as the lightning continued to blast into Izuku from the sky.
"FUCCKKKKKKKKKKKKKKK!!!" Izuku screamed as he struggled to his feet while the lightning continued. Izuku raised a fist towards the lightning in an attempt to hold it there and stop hurting him. The bulky Izuku lost the smile on his face. "You had a quirk to use lightning remember the feeling and let the lightning I am using fill you and return your power."
Izuku could feel the lightning hitting him but he couldn't absorb it he could barely stop it. "I am trying! I lost my powers, I can't just learn new powers."
The bulky Izuku stopped the lightning. "You disappoint me, I guess your powers were what made you strong cause clearly you couldn't of done what you have otherwise. Yo Pillar we don't get along but I think you may be the only one who could do anything."
An Izuku with short black hair with a red tinge smiled as he came into the arena and stood there. "So your the Izuku who can cross dimensions. You got taken out by muscle boy there he barely even used his quirk. You are pathetic, let me guess your mom died and you couldn't do anything. Just like her everyone else you care about right now could die or be dead and guess what. You. Did. Nothing."
Izuku was pissed he ran at the other Izuku and went to punch him. The short haired Izuku dodged with ease and suddenly there was blood pouring from Izuku's arm. "That was weak, predictable and too full of emotion. Anyone who has any skill wouldn't be hit by such an obvious punch." The short haired Izuku mocked as he lunged and Izuku, he placed a hand on his chest and smiled. "If you get up maybe I'll believe you can learn to not be so pathetic."
What looked to be an array appeared behind him in the shape of many circles. "This is similar to your railgun but only using one quirk." Izuku felt as an absurd amount of pressure was applied to his chest, Izuku felt as all the air in his lungs left and suddenly he felt like he had been launched into several walls. He went pale as he saw the array behind the other Izuku collapsed inwards and towards him. A surge of blood erupted from his mouth as the pressure shot him to the ground.
"Now get up and I will teach you the secret to learning the abilities you don't have." Izuku felt the weight of several buildings from the attack as he struggled to even move. The short-haired Izuku stood over him looking down on him with disgust.
He turned around and was about to walk away when Izuku grabbed his ankle. "I...Will....Get....Up." Izuku said using the short-haired copy as a support to crawl to his feet.
"Test 1 was a success, now you should be able to learn. Now I will just give you some information on me. I killed All-Might, All For One Shigaraki, Aizawa, and many others. I was a villain but I know I did what needed to be done. You must be ready to do whatever it takes."
