A/N: Hey guys, it's ZygardeFusion, collabing with EagleByte on a brand-new story! We just PM'd each other, and we built this story up from that. In case you're wondering how it's going to work, me and Eagle will write a chapter together, and we'll see how it goes!

Chapter 1: The Incident

?'s P.O.V

"Sirs, the World Collider is ready." An Octarian scientist reported. "When we turn it on, everyone from our worlds shall be thrown into the objective point, the empty Inkopolis."

"Excellent." Came an evil voice.

"When that happens, we shall show them the combined wrath of the Neo Octarian Menace!" Another voice cackled, sounding disturbingly similar.

"Turn on the machine!" The two voices yelled.

"Sir, yes sir!" Came the obedient voice of the scientist.

The two voices laughed like classic villains before a white light enveloped them all.

Antonio's P.O.V

Well… that was a strange dream.

I had went to bed in my apartment, a bunk above my brother, and then I had a strange vision of two massive glowing bubbles, one that looked like my home, Inkopolis, and another bubble that looked like another version of Inkopolis colliding into what seemed like an empty version of Inkopolis, filling it with people. Right before I felt a wave of gravity pulling me in, I saw a boy who looked 16 looking at me. His tentacles were a light green color, cut longer on the right side than the left. And his right arm and hand from the elbow down was also a lime green, seemingly cybernetic. I woke up in a house with another bunk parallel to mine, and I jumped when I saw that boy from my dream.

"GAH, WHO THE HELL ARE YOU?" He yelled.

"And who the hell are you?" I shot back. At that moment, my brother woke up in shock, pointing his Light Tetra Dualies at the stranger.

"Alright, tell me who you are and how the hell you got here, or I'll blow the shit out of you!" Mariano then yelled.

The boy pulled out what seemed to be a Hero Splatling Replica. I then pulled out my Hero Roller Replica, only to find that it was my real Hero Roller. Armed with that knowledge, I prepared to activate my green mod and blow his brains out. Before I got the chance, though, he smoothly swiped the roller from my hands and swung it over at Mariano, disarming the both of us.

"Listen here, kid," the other boy spat, his weapon raised. "I have no reason to tell you my name or what I'm doing here. Rather, I should be asking you the same." He glared at the two of us, and his face softened up a bit. "Sorry, just...overreacting. Judging by your roller, I'd say I can trust you enough. I'm Josiah, also known as Agent J for the New Squidbeak Splatoon."

"Wait, how do you know about the New Squidbeak Splatoon?" I asked. "I thought that was a secret."

"I've been in for a little while, not much more than a couple weeks," Josiah said. "Now, what about you?"

"Well, I'm Antonio, or Agent 4 of the NSS." I began. "I'm also the leader of Team Overdrive, one of the freshest squads in Inkopolis."

"Woah, hold up," said Josiah, puzzled. "First off, you don't look anything like the Four I know. And second, I thought turf wars were banned two years ago when the Octarians took over."

"Wait, who are the Octarians?" Mariano asked. I then realized that he wasn't aware about the Octarian Menace, so I filled him in.

"We should check the Square, then." Mariano pointed out. "If the Great Zapfish is there, we know something's up."

[Scene Change, Inkopolis Square]

We stood on a rooftop, anticipating our next move. Josiah ran to the edge and jumped across, landing on another rooftop. "Come on," he said, motioning for us to follow. "It's only about ten feet, anybody can jump that!"

Mariano gulped but ran ahead, jumping easily across the gap. I did the same, following closely.

Eventually, we reached the Square, and the Great Zapfish was there, wrapped around the tower.

"Did we really have to jump rooftops?" Mariano asked. "We probably could just blend in with the crowd down there."

"Nah," Josiah said. "Knowing the Octarians, they would have spies."

"Then if they were out for ink, why didn't they splat anyone yet?" I asked. "At least we know that the Great Zapfish is there. We know that something has happened."

"Well, there's a difference between spies and suicide bombers." Josiah explained. "If they wanted to find information, they would do it quietly. If they were out to splat people, they would have already done it. And we're not taking that chance of being spotted, I've seen what these people can do firsthand, and it's not pretty. I mean, look at my arm."

"Man, you're a good leader." Mariano said. "Speaking of leaders, why don't we look for Marie?"

"For once, you have a good idea." I joked.

"What do you mean, FOR ONCE?!" Mariano yelled.

"Keep it down!" Josiah hissed. "I see Octarians over there!"

He was right. I noticed that some Octolings were patrolling the rooftops, clad in black stealth suits. Technically, they weren't stealth suits, as we saw them quickly. The suit was unlike anything I'd ever seen, featuring a black leather crop-top, black leather skirt, and a pair of black glasses with one eye glowing red. Their shoes, too, were black high-heel boots, quite impractical looking.

"Wait, what are they wearing?" I whispered. "I've never seen those before."

"Those are actually standard issue for the Octolings. I'm surprised that you haven't seen them before." Josiah noted.

"Guys, I know you're the ones who've seen Octolings before, but shouldn't taking them out be our priority?" Mariano asked.

The moment he said that, the Octolings saw us and tried to flee, running in the opposite direction.

"Don't let them catch us!" One of the Octolings yelled.

I activated my yellow mod and flew through the air, hellbent on splatting them. I saw Josiah and Mariano run behind me, throwing Splat Bombs, Burst Bombs, Suction Bombs and Toxic Mist at them. Because they had to take time to avoid the projectiles yet still move forward, we managed to splat them and check what they had on them. The strange thing was that their splatted forms acted like they were flying to a respawner, minus their gear. We decided to loot their gear, to get a better idea of what was happening. We took everything that they had, then went to Cuttlefish Cabin.

[Scene Change, Cuttlefish Cabin]

"Antonio!" Came the voice of Marie. "Something strange happened."

"Can I assume that it has to do with people who act like they don't know how they got somewhere, and people don't know who other people are?" I answered lazily.

"Wait, how did you know that?" Marie asked. "Did it happen to you? And who's behind you?"

"Well, I'm Mariano, Antonio's brother." Mariano explained.

"Marie, you already know me, seriously," Josiah said with a confused look on his face.

"Wait, are you Josiah?" Marie exclaimed. He nodded, still confused. "The other Marie told me about you."

"The other Marie?" I asked.

"This day just keeps getting more confusing," Josiah sighed.

"Come in, we have a lot to talk about." Marie turned and went inside the shack.

A/N: Honestly, this collab may end up good or bad, depending on how much effort we put into it. We might not be able to write chapters as often, due to An Adventure of a Lifetime, Saviors from Below, our SWC One-Shot Project, and life and stuff. Well, until then, this is ZygardeFusion and EagleByte out!
