(Before the Final Battle)
Izuku stood there, seemingly waiting for something when, suddenly, explosions could be heard. The explosions got closer as his childhood friend, Katsuki Bakugou, got closer to his position.
When Katsuki landed he immediately snarked, "Why the long face? Let me guess, he turned into a baby?"
Izuku responded with a semi-shocked semi-reminiscent expression. "Among other things, yea. What are you doing here?"
"It's the EPR paradox. Eri's quirk, I mean." Katsuki started as he stood next to Izuku, "Instead of letting her get enough control to push All Might through time, you idiot's ended up pushing time through him. Least All Might 'aint injured anymore." Bakugou muttered that last bit.
"Someone could have warned you against it," Katsuki said with a smirk on his face.
"You did," Izuku rolled his eyes.
"Oh really? Well, thank kami that I'm here." Katsuki said before pulling out a fixed version of Gran Torino's cape. "Regardless, I had it fixed. Back to how the old geezer wore it."
Izuku looked at the cape, emotions threatening to spill out of him regarding his former Sensei. He looked to Katsuki, tears in his eyes.
Bakugo sighed before looking out to the destruction that was Japan and its cities, "I just want peace. Resentment is corrosive, I understand that now and I hate it."
"M-me too, Kacchan," Izuku said, regaining some of his lost composure.
"We've got a shot at killing All for One, but I gotta tell you my priorities," Kacchan said, a stern expression on his face.
"Avenge what we lost? I hope, yes. Keep what I've found," He said, finally looking to his best friend, "I have to at all costs."
There was tension and silence for a moment before Katsuki snarked, "And, maybe not die trying. Would be nice."
Izuku chuckled, the tension being lifted from his shoulders before he held his fist out, "Sounds like a plan, Kacchan."
Kacchan paused for a minute before pulling something else out. The object in question was a Limited Edition All Might trading card which depicted All Might in his prime form. It was signed by All Might too. "Here," Kacchan pushed it towards him.
"K-Kacchan, I don't know-" He tried to argue, betraying the sparkle in his eyes at the rare piece of All Might merchandise.
Katsuki scoffed, "Why not? He signed it for you. Plus, I've gotta give it to you before Eri sees it and decides to keep it for herself."
Izuku took the card looking at it for a moment before seeing that, not only was it signed by All Might but by Katsuki as well. Tearing up, Izuku looked back to Bakugou, "Thanks, Kacchan."
"Yea... Will, you can that a little quiet? I didn't bring one for the whole team." Katsuki said before realizing and asking, "We are getting an old team, yeah?"
"We're working on it," Izuku said, determination glowing in his eyes.
(During the Final Battle, After Shigaraki levels the battlefield, decaying himself in the process.)
Through the rubble of a decaying building, Shoto Todoroki and Katsuki Bakugo managed to escape Shigaraki's "Suicide Stand". They found Izuku standing over the edge of the cliff they were on.
It was absolute chaos all over. Nothing but rubble, dust, and nomu bits everywhere, with All for One, with a face completely healed topped by white fluffy hair, sitting on a rock in the center.
Katsuki's eyes widened before narrowing as a scowl crossed his face, "What's he been doing?"
"... Absolutely nothing," Izuku replies with an uncomfortably neutral expression.
Shoto looks throughout the battlefield, his eyes stopping on All for One, "Where is Shigaraki?"
Izuku tilted his head to the side, seemingly contemplative, "Somewhere under all this."
"All I know is that the white-haired bastard doesn't have 'em." Katsuki flexed his hands.
Izuku nodded before standing up tall, "So we keep it that way."
"You know it's a trap right?" Izuku says, looking at Shoto and Katsuki with a raised eyebrow.
Todoroki looks to his green-haired friend "Yeah."
"We really don't care," Katsuki says, surprisingly omitting his usually foul language.
Izuku nodded, balling his fists.
"Good. Just as long as we're all in agreement," he says as green lighting begins to frantically spark around his body.
"Let's kill him properly this time," Izuku says, with the voice of the First hidden underneath his own, as he activates 100% of One for All.
They each stalk closer to All for One. To the End.
As they slowly approached All for One, the Demon Lord looked on at them. "You could not live with your own failure. Where did that bring you? Back to me."
The three powerhouses of 1-A circled All for One, ready to battle. "I thought that by using Shigaraki, I could control his body. Become the Ultimate Life form. But," he looks to Izuku, "you've shown me that's impossible."
"And so long as there are those that are capable to remember what was, there will always be those that are unable to accept what can be. They will resist" All for One says.
Katsuki opened his palms, ready to use his quirk and kill the evil bastard at a moment's notice, "Yup, We're all kinds of stubborn."
All for One smiles as he rises off his seat. "I am thankful. Because now, I know what I must do."
"I will shred this world down to its last bit of resistance... and then, with my brother's quirk that you've cultivated for me, create a new one... under my image. One that knows not what it has lost, but only what it has been given."
He looked to the three children, "A grateful world."
"Born out of blood," Izuku counters.
All for One raises his hands, "They won't know it... because you won't be alive to tell them."
