Ultraman and Heat Wave stared at the sight of the hero groups rushing onto the scene. It was then that Captain Cold and Heat Wave locked eyes, the two members of the Rogues, finally united.
"Lenny….you made it." Heat Wave gasped.
"Well, aren't you a sight for sore eyes, Mick. Didn't expect you to be the one they'd resurrect." Captain Cold said.
"Yeah, well, guess I'm just lucky." Heat Wave answered. "You probably have questions, me too, but let's put 'em on hold 'til we beat Big Bird here, yeah?"
"Couldn't have said it better myself. We'll save it for later." Captain Cold said. "Working with you like this… It reminds me of the old days."
"Yeah. It does." Heatwave said as the two looked to Overhaul.
Some of the heroes then ran up to Ultraman.
"You're not hurt, are you?" Glimmer asked.
"I'm fine… but my Guzzlord needs help. So does the boy. He's lost his Quirk...and taken massive damage." Ultraman said.
"Mirio? No way…" Tsumugi said. "We understand. We're on it!"
Nighteye came over to the badly damaged Mirio and Eri as he knelt down to them.
"Get Eri out of here… she's behind me." Mirio groaned.
"You did well...and you protected her. You did good, Mirio." Nighteye said grabbing onto both of them.
"Blondy's got Birdbrain backed up!" Heat Wave said as Izuku and Aizawa charged in, the latter using his Quirk on Chisaki. "Finish this, you two!"
"Time to wake up, Chrono!" Chisaki shouted as a strange hair went and slashed Aizawa.
"Heh...I got you with the hour hand." Chrono said as Aizawa slowly blinked as he was quickly taken down below with Chrono.
"Finally. No more distractions!" Chisaki said, completely wrecking the hall and reforming multiple spikes.
"Sonova…!" Heat Wave cursed as he narrowly avoided being impaled. "We're not gonna get anywhere if he keeps doing that."
"Nemoto...you did well to help me. Don't worry. You'll give your life for me!" Chisaki said, grabbing Nemoto as both were disassembled before ending as a strange fusion of the two. "Ah...much better."
"He used his own men to fuse himself?! Is there any low this guy won't sink to?" David asked. "You know what...don't answer that."
"I know this is a given at this point, but your powers are bullcrap!" ZS shouted at Overhaul.
Chisaki simply looked on as more spikes went at the group. "You all...are filthy...diseased." he growled.
"He can use hands that aren't his own?" Jexi said. "Though...I guess those are his now."
"Only disease I see here is you." David said. "Guess that makes US the cure."
"Well when you think about it, aren't we all both the-" Bow said before Overhaul attacked and Bow doghed. "Yikes!"
"Don't talk. Chisaki...he's not going to give up Eri without a fight...even if he ends up killing himself for that goal." Ultraman said. "And any damage we inflict on him...he can just repair it using his Quirk."
"A guy with an ego problem that removes any damage dealt to him. We've dealt with these kinds a lot recently." David said.
"Eri...a lot of people are gonna die cause of you!" Chisaki said, sending a wave of spikes at Eri.
"Eri!" Ultraman shouted before he looked in shock as one spike pierced right through Nighteye who stood and took the hit.
"Sir Nighteye!" Mark shouted in shock as he dashed over to where he was hanging. "Hang on, I'll get you out, get you healed up, and then-"
"Mirio….get...Eri...out of here." Nighteye said as Mirio started to try and get her out. "Healing...won't work. I've already seen the future."
"Screw that! Changing the future is our specialty!" Mark argued as he tried to carefully remove Nighteye from the spikes. "Just hang on. We're all getting out of here and going home."
"Don't. If you remove him like that, all of the blood in his body will gush out." Law said. "His organs have been damaged. He needs to get to a hospital."
"And that's assuming this guy even lets us out of here." Captain Cold said.
"Cold is right. We need to defeat him first." Cheetah said.
"Don't… please." Nighteye gasped. "I've seen the future. None of you escape alive. You'll all die at his hands."
"Dying doesn't scare us. Some of us have died already." Heat Wave said.
"Some of us more than once." Crusadermon said.
"The future...it isn't something set in stone. People may be able to see it...but that doesn't mean it's concrete! If it hasn't happened yet, that means there's still time to change it." Jexi said as the ceiling above began to break apart as Ryukyu's team fell through.
"Sorry we're late. Hope we didn't miss out on too much." Himeno said.
"Actually, you're right on time." Hope said.
"Enough of this." Chisaki said quickly, grabbing Eri as he hit the ground as he rose up on a pillar. "As long as I still have her, I can always start over!"
"Eri!" Izuku shouted as Eri saw Lemillion's cape in the wind. As she reached for it, her horn glowed as Chisaki found himself and Nemoto separating to how they were before as she leapt at the cape.
"Their fusion is dissolved. Now's our chance!" Cheetah said.
"(It didn't dissolve. It was undone. Eri...now I understand. Her power is...the ability to rewind.)" Ultraman thought. "You, you're Deku, right?" he called out to Izuku. "Please...can you help me save Eri?"
(Cue: Might+U- My Hero Academia OST)
"Of course!" Izuku shouted as they dashed at her. "Eri!" he shouted as the two of them went and grabbed her as she fell. "(I failed before...I won't let it happen again!)" he thought.
"Give her BACK!" Chisaki shouted as multiple spikes came soaring right at the three.
"I don't think so!" Tsumugi said as she used her Law of Cosplay to turn into Zoro as she quickly started slicing the spikes. "There's too many." she said before seeing Izuku, Ultraman and Eri suddenly disappear. "What?" she said before looking high into the sky. "When did they…"
"Wha, what, what the heck?" Ultraman said. "We just flew right into the air?!"
"Did...I...use it at 100%? No. Impossible. If I did, my leg would be broken but...it still feels fine." Izuku said.
"Wait a minute…" Ultraman said, looking at Eri. "Of course! Eri's-" he said before the ground rumbled as Chisaki emerged in a new fused form. "He fused with Rikiya this time!" he said as Izuku felt pain over his body.
"She has no control over it. She may have activated her Quirk but she's got no idea how to turn it off. She can rewind people. That's her secret. Use her right and you might make someone a monkey. Carry her like that and you'll be annihilated. Didn't I tell you she's cursed? Hand her over and I can disassemble her, or do you want to be wiped from existence?" Chisaki asked.
"You don't deserve to call her your daughter, the way you've been manipulating her." Tsumugi said.
"Actually, he's not her father." Ultraman said.
"I kind of figured when I first saw him. It's just a guise to manipulate her." Tsumugi said. "But when Izuku and I first saw him, we swore together… That we would free her from his madness, no matter what!"
The three of them then joined forces as they went against Chisaki as the fight continued to escalate bit by bit. Throughout the fight, Chisaki recalled how much he risked to get to this point. And at the end of his rope in the air, he finally snapped.
"Why won't anyone… take a look at the big picture?! What I'm going to do is tear down this world, its very framework! I'm going to restore the world to how it used to be! You all are just pretending to be heroes!" Chisaki roared going on the attack once more. "I WON'T LET YOU STAND IN MY WAY!"
"No, you're wrong!" Tsumugi said. "I had a hard time adjusting to this new life, but I always remembered one thing. Although the old Tsumugi died when my memory was wiped, I accepted her as a part of me. And now, I've decided that I'm going to embrace this new life, and show the world and beyond, that even a cosplay-cat mastermind like me and turn her life around, and be a hero in her own right!" Tsumugi then opened up her Law of Cosplay wide as it glowed brightly. "Take a good look… at what my power is! Law of Cosplay Bond Rule... Engage!"
Thousands of outfits belonging to everyone Tsumugi knows flew out and swirled around her, emitting a bright light.
"What is this? Is this supposed to help you?" Chisaki said, striking at her.
"For someone like you, who only sees people around them as tools for their own gain, this power is something that you will never understand!" Tsumugi said. She began shifting through her various forms as they all appeared one by one beside her. "The great lands and seas constitute one world. A billion of them form a universe from which great people live in. Add that universe to the others among this multiverse, and there's no hero that will not arrive!"
Tsumugi and all the heroes then glowed gold.
"The Billion-Fold Multiverse...!" Tsumugi called as she and all the heroes rushed down to Chisaki and battered him like he was in a meteor shower of punches, slashes and blasts, ending with Tsumugi punching Chisaki in the face with all her might. "...Storm!"
After Tsumugi's onslaught, Chisaki could only look up as Izuku, at 100% One For All, delivered a barrage of punches that further damaged the yakuza. Finally, the young hero delivers a final blow that punches Chisaki's mask right off, sending him down to the ground.
"This...is not within anything I saw." Nighteye groaned as the heroes rose to the surface. "Did they actually...change the future?"
"Damn straight they did." David said.
