Izuku shook Dimentio. "Dimentio!"

Olivia hurried over. "Izuku? What happened?!"

Fawful gasped.

"Dimentio just suddenly passed out!" Izuku cried. "He looked like he was in pain and then he-he collapsed! Now he won't respond and I'm worried for him!"

"He doesn't look injured," Olivia said, worry in her voice. "Fawful, didn't he say he was a clone of Dimentio? Do you think killing the clone..."

Fawful shook his head. "Dimentio is still breathing. He still of the alive-ness."

"But he must have felt the clone's pain. Izuku! Have you seen Olly? Last we saw, he was headed to y-"

There was a loud crash. Izuku handed Dimentio to Olivia and went to investigate with Fawful. Izuku peeked around a corner. Somebody staggered back from the wall, tail swishing side-to-side. Their hair was a mess, clothes torn, and unfolded wings making it seem larger than it already was. Izuku felt a shiver crawl down his spine as they slowly looked to him. They growled. Even with their mouth shut, there was a single snaggletooth that looked exceptionally sharp.

"G-what the? What kind of Quirk is that?"

"Not a Quirk," Fawful corrected. "It's of the magic. Magic from the kingdom of Mushrooms."

"Does that mean-"

They charged Izuku without hesitation, tackling him to the ground. They scratched Izuku's face. Izuku pushed their face away and kicked them off of him. He charged One-for-All and was about to punch them back when Olivia ran between them.

"Stop! Stop! That's Olly! Can't you tell?"

Izuku examined him. Olly...definitely looked...different. His crown was nowhere to be found, and he was covered in raggedy fur. Instead of folds and creases, Olly had a thick tail and goat-like legs and ears. He had two pairs of sharp horns, which had apparently left holes in the wall he'd crashed into shorty before. His wings looked the same as before, but was bare skin instead of feathers and held claws at the top. Olly was slouching slightly and his knuckles nearly dragged on the floor. He was also a lot taller than before, possibly gaining extra height from the hooves.

"Uhuh...Are you sure?" Fawful checked.

Olivia nodded. "I can tell. He's weird right now, but it's still him. And I know he wouldn't hurt anyone! He's just confused, is all!"

Olly growled.

Even though he tried to attack Izuku, Izuku saw that Olly stopped as soon as Olivia came into view. He seemed to be very protective of his sister, and this situation only proved it further.

Izuku sighed. "What happened to him?"

"He mentioned Scara?" Olivia mentioned.

Olly hadn't taken his gaze away from Izuku. Izuku noticed his eyes were dark purple, instead of the deep brown and yellow it used to be before. Olly's face looked a bit more aggressive when Izuku looked at him, and softened back up a bit when Izuku looked back to Olivia.

"He doesn't seem to like me," Izuku said. "Scara was the genie, right? I think she mentioned a curse."

"Yeah, he mentioned one too. Olly's been looking quite sick for a while now, so I've been worried about him for a bit."

"What happened?" Izuku asked, trying to keep eye contact with Olivia instead of looking to Olly; which was quite hard since Olly was a lot more obvious.

"Olly collapsed. I went to see if he was okay and saw him turn into...that. It looked painful. Before he passed out, he snapped at Dimentio's clone-"

"C-clone?"

"You didn't know? A clone of Dimentio tricked us into meeting. He brought Fawful back to life with a wish. Fawful saw through his illusion-he was disguised as you, by the way-and Dimentio tried to attack Fawful. That's when Olly snapped at him and fainted. Olly ran off and Fawful stopped me from chasing him. But then we heard you yelling and thought you were in trouble. That's when you met up with us."

Izuku looked to Fawful. "Fawful, huh?"

"Of the Beanbean!" Fawful cheered, making Olly growl again. Fawful flinched.

Olivia faced Olly. "Olly, I don't know what's going through your head right now, but you need to come to your senses, alright?"

Olly grumbled something.

He suddenly looked to the left, his ears twitching. He took off running towards the exit of the museum. Olivia hurried after him, flying as fast as she could manage.

"Olly! Come back!"

Izuku and Fawful followed, coming to the entrance to see Olly taking to the skies. Olivia sadly stared up to him. Yoshiro ran to Izuku, the rest of the class following. They all started to speak at the same time in a panicked manner.

"Hang on, hang on! One at a time! We have a lot of things going on right now, so please talk one at a time!" Izuku waved a hand, signaling them to calm down.

They stopped and Yoshiro began. "Midoriya, a woman came into the museum. We heard a crash and we all looked away for a second. When we looked back-"

Kana interrupted him. "Olive was gone and so was the lady! She was doing the tour with us and then she took off with Olive when we were distracted!"

"We need to find him!" Netsu continued. "He still has the Chaos Heart thing so if he looses control again then that lady will be in real danger!"

Fawful had went back inside while the students were explaining their reason for their panic, and came back out shortly after. "Insane funny man! He is gone! He was also taken by the lady!"

Olly suddenly stopped flying, then fell back down.

Olivia hurried to catch him, being crushed in the process. She did, however, catch his fall. And she didn't seem injured when Izuku helped her back up. Olly scrambled to his feet and growled at the sky. Izuku looked up, seeing a large structure appear in the sky.

"What is that?!" Izuku gasped.

Kieru pointed to the street ahead of them. "There's the lady! And she has Dimentio!"

Izuku recognized her. "Darling Long, the number two Pro Villainess in China. Oh, she's despicable." Izuku ran over, the rest of his class following. "Darling! Put him down, now!"

"I don't think so." She spoke calmly.

Dimentio opened his eyes a bit and smiled vilely to Izuku. "Heh...Heheh...Ha...AHAHAHAHA!"

"You were-" Izuku started.

"Yes," Darling explained. "We made a deal when you abandoned your post at the restaurant. He agreed, and we already have one half of the puzzle. We just need to get Dimentio to complete the fusion."

Dimentio coughed. "Fusion...? What are you going on about? Last time I created a fusion, I died!"

"I know. But this time, you won't fail. You cannot fail. If you fail, you fail us, and our mission. And you made a deal. A deal is something you cannot stray from."

Olivia stomped a foot, trying to be tough and assertive. "Let him go! He's hurt!"

"And what will you do if I do not?"

"I'll...I'll...I'll sic Olly on you! Olly, bite her!"

Olly stared at her, unresponsive.

"We'll heal him, you have no need to worry. It's simply an error within the THREEDEE Printer his clone was made of."

"Guh...What?" Ashi mumbled.

"And your brother does not scare me. My Quirk is far more deadly than his will ever be."

She grabbed Dimentio with her tail and stood straight. She grabbed her hair, whipping her head side-to-side. Izuku stood in front of his students and the twins. Her fingernails turned to claws, fur and a larger form tearing through her dress. She growled as she took to the sky, holding Dimentio firmly with her tail. She glided up to the structure.

Fawful pulled out a blaster and shot her eye. "Get back down!"

She curled in the sky and rubbed her eye. She glared at Fawful. "You pesky rat! I tried to leave without causing a fight, but seems like you've called for eternal punishment!"

She spun faster, clouds forming overhead. Olly took to the skies as lightning struck between the clouds. She tossed her tail at Izuku's direction, a strike of lighting following her command. Olly dove down and stopped in front of Izuku. His halo glew a deep red as he held out his hand. The lightning stopped on his hand. He pulled it close, forming it into a ball, and fired it back at her with more strength. He flew after it, charging her. She avoided it, but not Olly. He tackled her in the sky and bit down hard into her neck. She screamed, tossed Dimentio into the open door of the structure, and fell to the ground, becoming herself once more. She foamed at the mouth, a pair of horns that matched Olly's growing out her forehead, replacing the horns she had in her dragon form.

Olly landed next to her and stroked her head, purring softly.

Izuku lowered his arms. "Olivia, I'm glad Olly's on our side."

Darling got to her feet, her eyes glowing purple just like Olly's. He pointed up towards the structure and growled. She went back into her dragon form, taking flight, with Olly following. Darling struck the structure with her tail as Olly attacked the now closed door. It didn't budge until she struck it with lightning, which caused it to fall from its place in the air. They both landed, Darling back to normal once again, and Olly ripped the door off its hinges. He tossed it into a nearby building, destroying the entire bottom layer of it and making it collapse. Thankfully, everyone made it out alright.

The shadow of a tall person stood in the dark doorway of the structure. They were lanky, from what Izuku could see. The rest of it looked like a blob. They spoke in a metallic tone, with a hint of Dimentio's voice inside it.

"Izuku? Is that you? Really? Wow, you look so pathetic! AhaHA! You'll be dead within a few minutes. And then, we'll get those kids out of the picture. Wanna play a game? It'll be fun! We might even let you win if you're any good!" They spoke fast and cheerily, some words slurring together into others.

Olivia hid behind Izuku a bit more than before. "Izuku, who is that?"

"Us? We're new here, but we think our name is Super DimentOlive. It has a nice ring to it, doncha think?" They pointed at Izuku, revealing lights lining their knuckles, and ruff around their wrist. "But enough about us, we want to see your lovely little friends there. How do you think they want to die? We know a million ways to kill someone, and most of them only take a second to do!"

"Wait, is that...Olive's voice?" Ashi asked.

"And Dimentio's..." Kieru added.

"Darling mentioned a fusion," Olivia told Izuku. "That must be the fusion. But it happened so fast! Don't spells like that take a while to cast?"

"Oh! A clever one, aren't you? Well, Create-O-Guy isn't from your world, so he doesn't need magic! Oh no, he used technology to bring us to life! And look at us! Wow, what a technological marvel!" They spun on one foot, examining their clothes. "Oh, wait. You can't see us, can you? We'll move into the light to you can bask in our glory."

They walked out of the building, letting the sunlight slowly illuminate them. They wore a long hat that nearly dragged on the ground, a tailcoat with diamond-shaped edges, and a large ruff around their neck that made their neck look exceptionally long. Purple roots were visible through the fade to blond, and a decorative purple belt was hung loosely above their long, puffy pants. Instead of pointed shoes, however, their legs were thick, metallic, and glew blue. The symbol of a club could be seen on the front of their feet.

"Oh no," Netsu hissed. "Olive...the Chaos Heart...Dimentio...!"

"Yep! We're another creati-i-i-on of the Chaos Heart! A pleasure t-t-t-t-t-to meet you!" Their voice glitched as their body twitched and sparked. Izuku noticed markings on their face that made them look like a clown. They held out their arm to Netsu. "Come on, shake our hand! We're friendly, we promise!"

Olly growled but did not attack.

Olivia cleared her throat to get Super DimentOlive's attention. "You...! Leave Netsu alone!"

They looked at her, nearly turning their head backwards. "What was that? An attitude? Oh no, we don't like attitudes." They turned around, their body moving to match the direction of their head. "We actually would prefer Darling stay like that forever. At least she's silent as a mouse drunken on sleeping medicine!" They went to Izuku, moving surprisingly fast. "And you. We know how you are. You try so hard to make other people like you that you-help-fail to see your own ignorance. How long will it be before that catches up to you? How long will you last before you inevitably crumble like a cookie that has been left too long in milk, and grew soggy, weak, and exhausted?" Their voice glitched, crying help in the center of the sentence that it didn't fit. Izuku realized that must have been Olive, calling for Izuku to help him get away from Dimentio.

"Stop this." Izuku pulled his hand into a fist. "I don't want to hurt you."

"Why?" They turned their head upside down, spade-shaped bells ringing. "Afraid you'll hurt Olive? Or are you so certain that Dimentio can be helped that you treat him like one of your own? You're afraid of hurting both of them, aren't you?"

Izuku said nothing.

"Weak."

They punched him in the gut, sending him crashing into a building. They skipped over to him. They bent over to look in his eyes.

"Dimentio doesn't want to change. He will never change because of it. So you best give up now-help us-and let Create-O-Guy complete his mission. After all, the more you stand in his way, the more we'll beat you to a bloody pulp! HAHAHAHA!" Their voice glitched again.

Izuku got to his feet, wiping blood from his mouth. He tried to strike them in return, but they simply stopped his fist with their hand.

"You couldn't beat the Chaos Heart Entity, and you can't beat us. Dimentio had a mental breakdown, so that battle doesn't even count! You're a weak, heroic wannabe, and you have no chance of beating us, or anybody else!"

They shoved him down, snapping a few bones in Izuku's arm. The students wanted to help, but knew Izuku would tell them to stay back. However, Izuku remembered that he told a friend of his he'd be in China, and remembered that he agreed to chaperon the trip if he got to beat some villains. And, lucky to Izuku, that friend was supposed to arrive today. If anybody could beat DimentOlive, Izuku knew it would be him.

Super DimentOlive was forced back by a huge explosion. "Gah!"

Bakugo forced Izuku to his feet. "You're getting beaten by a clown? Seriously?"

Izuku chuckled. "Yeah...You were right about the villain part. I mean, there was no way we were going to let a bunch of teens handle it like we had to do."

"No fair, no FAIR!" DimentOlive scrambled to their feet, stamping a metallic foot. "You have backup?! Well...We-we'll get backup too! Shadow Guy! Get out here and help us! If we lose, Create-O-Guy will fail! And we can't let them fail!"

Silence.

"Sh-shadow Guy? Hello? You don't want us to fight them alone, do you? We'll get toasted!" They pulled the bottom of their hat into a knot.

Still nothing.

DimentOlive chuckled nervously. "Uh...It seems like we have a bit of technical difficulties here..." They tugged at the ruff around their neck, revealing their neck was also metallic and extendable, like their arms. "We'll be right back after this short intermission! That's all, folks!"

Bakugo tried to charge them, but they simply teleported away. Bakugo scoffed and faced Izuku again.

"What was that?"

"That was fusion magic," Olivia explained. "Somebody named Create-O-Guy kidnapped Olive and Dimentio, fused them, and made Super Dimentio-Olive."

He pointed to Olly. "Care to explain the goat?"

"That's Olly! He's cursed. But...if Create-O-Guy can use magic through technology, he might be able to fix Olly! I'm sure this is all a big misunderstanding. We just need to meet Create-O-Guy and talk things out. That's what happened with Olly, and seemingly to Dimentio. Maybe we just need to explain our differences and talk them out! I'm sure that will help!"

"Mister Midoriya?! The ship is leaving!" Kana cried.

Izuku and Bakugo quickly turned. The ship sprouted metallic legs and crawled up the building to either side. It leaped off the tops of them, crushing the two top floors of each building. A yellow creature stuck his face from the open door, DimentOlive copying him.

"This isn't the end, Izuku," the yellow creature said.

DimentOlive laughed, bells jingling. "Create-O-Guy is mad at you now! You're going to pay!"

Create-O-Guy smacked them in the side. "Shut it! We don't need to taunt them unnecessarily. Let's see if they're really determined to follow us."

"S-sorry."

"And stop apologizing!"

"Sorry!"

"What did I just say?!"

"Sorry!"
