Katsuki had been fighting for almost ten minutes now, keeping himself just barely alive as he kept the slimy bastard away from his throat. Heroes were trying, at least half a dozen were helping, but they couldn't get past the villain.

His quirk and stamina had hit their limits. His arms hurt like hell as the slime forced itself onto him once again, stopping him from breathing as it pushed into his throat. His body felt so weak and pained, but he kept fighting with everything he could muster.

'DAMNIT! You useless fucking bastards, stop standing around and help me! Why are people just watching me die?! Do something! WHY ISN'T ANYBODY DOING ANYTHING!?' Katsuki was crying by now, desperate for anyone to help him. To do SOMETHING!

Just as he was on the verge of losing consciousness, he saw a flash of movement, someone running towards him like their life depended on it, and eyes emitting an emerald green glow. In that moment, in his panic, he had one thought.

'Deku...?'

Izuku arrived at scene, still in his new fiery form form. He shook with fear and terror as the events unfolded before him. The sludge villain who had attacked him not even thirty minutes ago was wrapped around somebody in the street of the Tatooine Shopping District.

'Oh no, that's the guy who attacked me! That can't be right, All Might captured him!' Izuku stared on in shock and fear as he remembered back to what happened on the roof, when he saw All Might's true form. His pockets had been empty.

'But the bottle, if he dropped it... That means it's my fault.' Izuku was wracked with guilt, eyes wide as he stared at the fires, the heroes hesitating to move.

"Why haven't the heroes done anything?! That kid's been stuck fighting that thing for a while now!" A bystander yelled, getting Izuku's attention.

'Oh god, I thought I'd die after only a few seconds of struggling!' Izuku covered his mouth, remembering the pain.

"Wait, I'm confused, isn't that the villain All Might was chasing earlier today?"

"All Might?! No way he lost! Where is he?!"

"Well, can someone call him or something?"

"Seriously, why hasn't he shown up to help the heroes?!"

Izuku and All Might were a mere ten feet away from each other, unaware of each other's presence, but they felt similar feelings as they heard these statements. Guilt and shame. All Might groaned in pain while gripping his chest, while Izuku held back sobs.

'I'm the one to blame, he wasted his energy on me!'

'I'm worthless!'

'He can't power up yet, and none of the other heroes have the quirk to stop this monster!'

'So pathetic!'

'It's my fault... I'm sorry, so sorry!'

'A disgrace!'

'Help will show up and save the day, I'm sure!'

'I'm not a real hero!'

'Someone, a real hero will come soon!' Just as Izuku had that thought, the slime twisted, and he could see tufts of ash blonde hair and a face that became more and more hauntingly familiar, despite the evil grin of the slime plastered onto the lower half of their face.

Then he opened his eyes, and Izuku instantly recognized him, despite the overwhelming fear for his life on his face.

It was Kacchan.

Before he even knew what was happening, he'd jumped over the crowd with a powerful burst of flames, shocking every hero who saw him, and grabbing the attention of the sludge, who looked over at him, confused and ready to attack.

Izuku just barely kept himself from stumbling as he landed, before dashing at full sprint towards the villain, towards Kacchan. He heard the shouts of a hero as he sprinted, but he kept running, panting.

'What am I doing?! Why am I running?! Why can't I stop?!' His mind was screaming at him to stop, to let the heroes handle this, but his body wouldn't listen to him as he sprinted wildly, arms flailing as he felt adrenaline pumping through his veins.

"YOU'RE TOAST, HERO!" The sludge villain yelled, getting ready to attack him. But in a bout of panic and quick thinking, Izuku recalled a page in his notebook about a hero's special technique. Make the opponent flinch, and use the opening to restrain them!

Izuku charged up a fireball in his hand, slowing down to toss it right at the villain's eye, bursting as it hit and blinding them for a moment. They reared back and freed Katsuki's throat, giving him a chance to breath and cough.

"KACCHAN!" Izuku shouted at the top of his lungs, clawing into the villain's body, ignoring the stinging pain as the slime hissed and bubbled from his lava-like hands.

The yell made Katsuki confused, not knowing why this person was yelling out Izuku's nickname. "What the hell?! Who are you?! Why are you doing this?!" Katsuki yelled, breathing heavily.

"It's me, you idiot! And I don't know, my legs just started moving on their own!" he replied, clawing at the slime as it covered Kacchan's face again

In that moment, he remembered so many times that he'd been told he couldn't become a hero, all flashing in his mind as he clawed into the slime, getting deeper and deeper, scraping away more and more.

"I couldn't just stand there and watch you die!" he yelled, on the verge of sobbing as he clawed desperately.

Behind the crowd, behind everyone who was watching, one man had been inspired by Izuku's words, even without knowing who he was.

All Might was inspired. And he began to bulk up, gripping the pole he was leaning on harder. 'I have to do something! No matter the cost!'

"Shut UP, you sentimental bastard! I'm done playing! DIE!!!!!!" The villain got ready to attack once again, having recovered from the blindness. His hand was coming down, about to crush Izuku.

"SAVE HIM! THIS THING'LL KILL 'EM!" The heroes yelled, finally running into action.

But, before anyone could do anything, there was an imperceptible burst of movement and high winds as somebody moved towards the two of them.

The fist of the slime came down, creating a massive burst of dust and smoke, hiding what had happened. But as it cleared, there was All Might, who had taken the blow in his full muscle form, slime sticking to his arms and face. Izuku had been whimpering in fear and covering his face with his arms, and he was shocked to see All Might, in his full, muscular glory.

"I MUST APOLOGIZE TO YOU TWO. IT WAS BECAUSE OF MY FAILURE THAT BOTH OF YOU WERE IN HARM'S WAY."All Might flexed his arm, lifting it up in the air and ripping the slime off of his arm.

"YOU WERE A HERO TODAY!" All Might shouted, blood rushing out of his mouth with every word as he grabbed Izuku and Kacchan by their arms. "TEXAS SMAAAAASH!!!!" All Might yelled out, throwing a punch that instantly burst the slime apart, as well as creating a massive force of wind.

The wind blew the two boys like paper in a hurricane, while the civilians on both side of the street were protected by heroes, who just barely managed to keep their guards up.

Even people halfway across the city could see as a tornado formed from the wind of All Might's punch for a few moments.

And as it subsided, the sky began darkening, and raindrops began to fall. When they started hitting the barely conscious Izuku's body, still in the form of the fiery alien, he woke up, feeling like he just got stabbed by a needle every time a drop fell on him.

Izuku got up from next to Katsuki, muttering 'ow' and 'shit' under his breath. He saw All Might standing proud, barely catching himself from falling back, but couldn't focus on it, the pain overwhelming him.

The fiery teen got up and tried to get himself to cover from the rain, ignoring everybody as he jumped over the crowd once again, barely catching himself from taking a nasty fall.

Izuku ran and ran, getting a fair distance away from the crowd, before he heard a loud beeping, and a red light engulfed his body just like the green light from not even ten minutes prior.

The reversion of his alien form was just as odd as the transformation itself, and changing from odd two-toed feet to normal human feet had messed him up, causing him to stumble and fall.

"What... was that...?" He mumbled, looking back at the crowd, where everybody seemed to be cheering for All Might. Izuku looked at his hands, seeing they were normal, and smiled weakly. "I... have a quirk... I really have a quirk... I guess my dreams are obtainable after all, then, Kacchan... I told you so..." He stood up, groaning.

Izuku walked towards some cover from the rain, his mind wandering. "Should I tell people about this? I want to be a hero, after all, and people will learn about it anyways... If Kacchan learns about it, he might get angry, especially if he knows I saved him. I'll hide it from him for now... Wait, can I update my quirk registry forms? That's going to be important..." He muttered, frowning to himself as his mind went a mile a minute.

Then, he perked up, a thought occurring. "But I need to tell Mom! She's the one person who should know first! Oh, she's going to be so excited!" Izuku told himself, grinning as he looked at his watch, noting the hourglass had turned red. He then began running home with a smile on his face.

Izuku got to the apartment complex he lived in, panting as he knocked on the door of his mother's apartment. He looked bad, sweaty, and wet after his run, but he still had a grin on his face, despite his pounding heart and exhaustion.

As the door opened, his mother, Inko Midoriya, a short, chubby woman with hair and eyes the same color as Izuku's, took one look at him, and gasped. "Oh no, sweetie, are you alright? You look so tired, and you're late! Did someone hurt you? Were you attacked by a villain?!" She asked, stepping aside to let him inside while also putting a hand on his shoulder.

"Y-yeah, I might've been attacked... but my day got better! Did you see the news about the sludge villain who attacked Kacchan?" Izuku's answer made his mother confused, eyes widening in concern.

"You were attacked?! Are you okay?! Did the sludge villain attack you too?!" Inko hugged him, tears welling up in her eyes. "I swear, if he hurt you, I'll... I'll... I don't know, I'd make him pay for hurting my baby!"

Izuku hugged back, regretting how he started the conversation. "Well, yes, I was attacked, but! I'm perfectly fine! I was saved by..." Izuku paused, remembering what happened after All Might saved him. "A hero... And, you're not going to believe this, but I have a quirk now!"

Inko's face went from concern, to mild surprise as the statement sank in, and then her eyes widened. "You have WHAT?!" Inko pulled away from the hug, eyes wide as dinner plates.

"A quirk! I can transform into some sort of fire alien!" He explained, before recounting the tale of how he found the watch, and saved Katsuki, watching Inko's reaction as her eyes widened even further, and she was in a perpetual gasp.

Then, before Izuku could even react, Inko got up close and hugged him as tightly as she could, squeezing a fair bit. "Izuku, I'm so happy for you, sweetie! I can't believe you have a quirk now!" She said, pulling away after a few seconds and grabbing his hand.

Then, a frown creeped onto her face. "I know this isn't the best time to say this, but... A long time ago, I said something awful to you, like I had just... given up on you. I've always regretted that. But you never quit, and I'm proud of you, Izuku. I'll cheer you on with all I've got!" She smiled up at him, tears in the corners of her eyes.

Izuku was silent, and then hugged his mom tightly, beginning to cry. She hugged back just as tightly, crying as well.

"You're going to be a great hero, Izuku."

So! Since this is on FFN and it doesn't have the same summary, commenting, and note systems as AO3, here's some review responses! And just so you know, updates will happen every few days up until Chapter 12, as this is just being cross-posted onto here now.

AnimeMasterDub: I wrote about Izuku getting the Omnitrix because I was like 'Oooh, what if Izuku got the Omnitrix instead of One For All'. I didn't want to write about Ben getting the Omnitrix in the MHA world or whatever, because that isn't something I thought I would enjoy writing. It would basically be Ben 10 but superheroes are more commonplace. And don't worry, more Ben 10 things will appear in this story.
