(Festa is shown viewing Luffy on one of the many screens in his tower. Amused, he sways off his chair and into an elevator which takes him down to an underground cave. The cave is lined with scattered bottles and papers on walls)

Festa: Excellent.

(Bullet is shown within the shadows of the cave.)

Festa: Now, it's time for your part in this plan. Are you ready to party?

"Bullet…"

"Smoker was right, Bullet and Festa are planning something." Midoyria said, looking up from his notebook.

"No shit, we knew that from the get go." Bakugo grumbled.

Endeavor spoke up. "What we need to know is why he wanted all these pirates here in the first place."

Suddenly an idea struck Nezu. "What if-"

Bang!

Before he could get the words out, the doors in the corner of the theaters burst open. All eyes went to the two figures who entered as the movie paused.

Two boys that were similar in height and size.

The first was a boy with grayish skin and pale hair, with small golden-brown horns jutting out from one side of his head. His eyes were Golden-yellow irises surrounded by black sclera that glowed in the darkness. He leaned on a large cane as he walked into the theater. The boy wore a dark yellow tunic and black pants, but no shoes or socks. Another noticeable thing was the thick tale trailing on the floor.

The second boy was similar, despite the fact that his skin was black, and in the place of hair were horns jutting out from his head, coiling and spiraling around each other like snakes. His eyes had the same yellow irises with black surrounding them. The boy wore a black tunic and pants with no shoes. He did however have large wings sprouting from his back. And in both hands he held a trident taller than he was.

The boy with pale hair spread his arms wide as he entered the theater. "All right, lets get st-"

He stopped as soon as he saw the audience. The boy beside him paused as well, staring back at the heroes and villains that filled the seats.

An awkward silence filled the air as neither party moved.

…

…

…

…

The pale haired boy turned to his friend. He whispered, "...Mohg?"

"Yes brother?"

"We had this room reserved until next month right?"

"Yeah…"

"So who the hell are they?"

"...Janitors?"

The silence went on again until Mohg spoke to the theater. "E-Excuse me, but who are you and why are you in our theater?"

Bakugo spoke first, unfortunately. "Don't ask us horn for brains, we were brought here by some asshole with blonde hair in a suit."

The brothers looked at each other for a moment. Back to the audience. Then back towards each other.

"You don't think…" Mohg asked.

The other brother growled. "Oh, I know. ALUCARD! Get the hell out here you goddamn thief!"

Above the audience, Alucard materialized in a burst of red light. His eyes fell on the brothers at the door and his face fell into a frown. "Ah shit, who let the broke brothers into the theaters? Morgott, I see you still haven't trimmed those ugly horns on your face."

Morgott snarled. "You wanna explain to me why you're in our theater when the schedule says it's our turn?"

"Simple." Alucard floated down to the brothers level. "I need this theater to complete a project. So I took it while you two were eating in the plaza."

A malicious aura surrounded Morgott as Alucard kept speaking.

"Maybe if you two weren't so busy enjoying the food, you would be more alert. I mean come on, I know you're still getting used to being an overseer but you two could at least act like you're not the starving rats we pulled out of those sewers."

"Fuck you!" Mohg called out meekly. "Maybe if you weren't such an overeager asshole-"

"First of all, I'm a lovable asshole. Try to get that through your nappy horn filled head before you come at me."

Finally the Dam burst, and the malicious aura held by Morgott blasted forward into the theater. Shattering cups, cracking the big screen, and even rendering some of the audience members unconscious. "That does it! You wanna fuck with us? Come see what that brings asshole!"

Morgott tightened the grip on his cane, shattering it, or rather the outer shell. It revealed a beautiful curved, multicolored sword that was pointed at the end. The weapon began to emit a low red glow, while in his other hand a golden translucent short sword appeared out of thin air.

Mohg had what seemed like…blood surrounding his trident, making it glow a bright red.

Alucard gave a devilish smirk. "Well, well. Looks like the brothers of filth think they can take me on! Alright then!"

Alucard clapped his hands, restoring the theater screen and shattered cups, along with awakening the people who fell unconscious. He then turned to the audience, "Forgive me for the interruption but there's something I need to take care of."

With another clap Alucard and the brothers disappeared leaving the audience alone.

…

…

…

"What the hell just happened?"

No one knew the answer, and before they could ask more questions the movie continued.

(The movie continues with the straw hat blasting past the previously introduced pirates.)

Donald: The straw hats jumped straight into the lead!

(The Sunny splashes down onto the rising waterfall)

Nami: Splashdown Complete

Usopp: Thank goodness

Hatsume was practically begging whatever god she knew to reveal the secrets of the ship. While others still trying to get over the interaction between Alucard and the brothers from earlier.

Sanji: That move gave us a good lead, but we'll need to watch out for attacks from behind.

"Wise man". Aizawa mumbled.

Luffy: Franky, that was so cool!

(Franky basked in the positive attention while the rest of the Straw hats prepared to reach the floating island. But before they could, their attention was drawn to the door unlocking and an injured Law coming through.)

Luffy: Tra-guy!

"Hey, that's the injured guy from before!" Kirishima pointed out.

"Yeah, but how'd he make it onto the ship?"

Midoryia pondered. "Maybe his abilities have something to do with teleportation? before he disappeared we saw him produce a weird energy sphere that included the ship."

"Whatever it is, we can be glad that the man is safe."

"But what'll he do now? He was found on another pirate ship without permission. And I dont think a man with a 1.5 billion bounty is just gonna laugh it off." Midnight reasoned, making the heroes and students nervous for the already injured man.

(Chopper is seen running to get medical supplies while the others are consoling Law.)

Now that was a surprise. It wasn't common to see villains assisting each other but this seemed genuine. The heroes only knew villains to fight with each other rather than with, of course there were a few exceptions to this rule like the league of villains.

Law: Don't bother, I'll be leaving here soon. And if you value your lives you'll do the same. Festa…He…

Robin:The man who's hosting this party?

Law: yeah, he's plotting something. And he's got some dangerous friends helping him out. I've already evacuated my crew, but this whole island is about to become a warzone.

"So Festa is planning to cause mayhem with Bullet. Not surprising however this does raise the question of how their partnership came to be." Shigaraki mumbled to himself.

Usopp: Well you heard the man, let's go!

(Tra-guy attempts to stand to leave, however Nami and Chopper insists he stays to get his wounds treated.)

Recovery girl quirked her brow. A doctor that was a racoon? Very unusual. Although she took orders from a mouse/bear that was the principle.

Others, both hero and villain, were surprised at the kindness the Straw Hats showed towards Law.

"Guess I could've been wrong." Nemuri mumbled.

Law:Forget I was here I don't need your help to see this through to the end.

Nami: Don't be ridiculous, look at yourself

Law: Don't worry, I'll pay them back for this.

"Law seems driven to do this by himself, do you think it's personal?" Kirishima asked Bakugo.

Bakugo shrugged. "Could be, I'd be pissed if some Extra's kicked my ass, Although that'd never happen."

Midoryia thought about such a theory. He's only seen law for a few minutes but he doesn't seem the type to hold grudges. Maybe it's a deeper reason. Maybe he actually cares about keeping Festa and Bullet from unleashing chaos.

(Before anyone could argue, explosions around the Sunny went off as ships behind them began to close in.)

Ussop: That didn't take long! The guys behind us are catching up! What do we do? We need a plan!

(Most off the straw hats sat in thought while explosions rang off around them)

Endeavor grunted. "They are pirates so we shouldn't expect them to help, even if it's what's right."

Luffy(With determination): We'll keep pushing forward! But we'll also help Traffy!

"Okay, Hold up!" All eyes trailed toward the blonde psycho known as Himiko Toga. "What kind of villain helps others? I was expecting blood when he revealed himself! I want blood! It's not fair!"

Himiko sulked into her chair, holding onto the arm of one Izuku midoriya for comfort.

"While I wouldn't go that far, she does raise a point." All Might stated.

Yaoyorozu raised her hand . "Maybe they've teamed up in the past. I recently read an article stating that villains and heroes are known to associate with those who are familiar to them".

"Or Luffy and his crew see the possible value in taking down a common enemy-"

Someone, a student, interrupted."Then wouldn't it be easier to send all of their crew members to take down Festa instead of also pursuing the treasure?"

"..."

The heroes were stumped with this question. Their job is to use all their efforts to prevent Villains from wreaking havoc on society, but now they witness a villain do the same. And for seemingly no reason.

No one knew what to think.

Until one student answered.

"Maybe he just wants to." All eyes went to Izuku Midoriya once again.

"What do you mean Midoryia?" Lida asked, confused at his classmate's suggestion.

Midoryia straightened, suddenly aware of all their eyes on him, but answered regardless. "We are heroes who're trying to apply our logic towards a villain…no, a pirate who obviously doesn't follow traditional villainous methods. Luffy isn't, or rather, doesn't seem to be the typical big bad villain. We've seen him smile and laugh, and enjoy time with his crewmates. Maybe he just wants to help Law because he wants to help a friend."

"And he wants to pursue the treasure because he's doing what he loves at the same time." Shigaraki finished Midoryia's thoughts to everyone's surprise.

Shigaraki and Deku looked at each other for a moment before turning back to the screen. Tomorrow, they'd be enemies in their own worlds. But today, they could come to an agreement.

Luffy: Chopper look after him

(Chopper exclaimed in agreement, much to Laws protests)

Robin: Then I'll come with you. We shouldn't run away. You mentioned Festa's dangerous friends, right? ANd some nefarious plots as well? If this is some sort of trap their lives could be at stake, besides, you piqued my curiosity. Any objections?"

"Well, we've officially identified the smartest person there". Ojiro mumbled.

Sanji: I don't mind as long as I can come as your bodyguard.

"And the biggest simp," Sero said beside him.

Brook: If it's a covert mission I might come in handy!

"..."

"Is that a fucking skeleton?"

(The straw hats all agreed to the plan in their own ways.)

Luffy( to Law) : Were teaming up again huh?

"Yaoyorozu was right, this isn't their first time working together." Hagakure confirmed from her seat.

(Law reluctantly accepted the Straw hats' help. And with the assistance of Franky, the group going after Festa falls down the waterfall in a shark submarine)

"I'm pretty sure it isn't safe to fall from that height!" Someone yelled out worried.

(Before they hit the water a dangerous speeds, robin activated her ability)

Robin: Mil Fluer!

(Thousands of hands sprout from the submarine's roof, forming wings big enough to let them down into the water safely.)

Again, the crowd went crazy at the sight of robin causing the Submarine to fly. Another ability that they couldn't explain. However Midoryia thoughts went to Shoji, who could replicate his body parts at will, but Robin's ability seemed to be on a much higher level.

Sanji: Nice one robin, that was close.

Ussop( Through the transponder snail): if anything happens just call us on the transponder snail!

Chopper: Let me treat you first Traffy!

Law: Sorry, there's no time. We're heading under the island, and putting a stop to Festa!

I do apologize for making you all wait such a long time. I wanted to try something different and expand this fanfic with some semi original, something I've never done before. If you don't know, they're based on Mohg and Morgott from Elden ring.

I would like to hear what characters you guys would like to hear more of.

And next time, we get to the juicy parts.
