Author's Note: Hey there everyone and welcome to this new fic! It is technically a Sanders Sides/ Ben 10 Xover but you do not need to have seen the Sanders Sides series to read this story and posting a Sanders Sides story is kind of weird on this site so it's not being tagged as a crossover. Characters from that series are put into the Ben 10 universe with an in-universe explanation. This story is mostly a Ben 10 world building story so more characters of different species were put in to show more of the universe. The explanation of their existence won't be explained and the plot largely foreshadows that explanation so chances are you will be confused at first but I hope you stick around. So, without further ado, the prologue!

Red. Green. Yellow. Indigo. Blue. Purple.

Against the pitch black of the night sky, the colors stood out starkly. Pure, solid streaks of color. They were intense and beautiful in the most beautiful way. Streaks crackling and dancing through the air, the sight was stunning but not peaceful.

The crackling and intensity came with power. It filled the air, flooding it so thickly that he could barely breathe. It was overwhelming in a way it shouldn't be. In the past, the colors were always a comfort. The colors were safe. They were friends. Family. They belonged together. What were they doing out?

Uncontained, darkness reached out for them, trying to pull them back in but something was preventing the colors' reunion. Somehow, he knew he was one of the colors. The memory flickered back and clicked into place. It wasn't alarming in the slightest. In fact, it felt right in a way he never felt in his own body.

Still, something was wrong. He didn't belong here, outside. Outside of what, he didn't exactly know. He just knew it was wrong, wrong, wrong. Wrong in every way. He felt broken, fragmented. He needed to get back. He didn't belong here.

The other colors crackled, seemingly as upset as he was. Indigo and Purple sparked like electricity with unease, Blue and Yellow's paths became frantic as they tried to get back, and Red and Green… Red and Green were heading right for each other.

"Remus!" a voice cried and he felt something. Something physical. Something outside of this memory of colors and the void of space. Physical awareness spread through him and he noticed the pain in his body but there was nothing he could do. His eyes opened briefly but closed again soon after. He had barely enough time to register his surroundings and a figure reaching down to touch him.

Contact was made and the pain eased. The noise, that harsh, chaotic noise, in his mind calmed and the image became clearer. The colors, pure and untainted, became all the more visible. They were agitated and upset in every way and so many more he couldn't think of. This was wrong, wrong, wrong and they needed to get back.

The dark form they came from was barely visible against their surroundings but he could feel it. It was there, calling out to them with a silent voice, but he couldn't find his way back. He clung to Red, both in the physical world and in the world his mind was trapped in. It was a massive comfort but it wasn't nearly enough. Red and Green were one but they weren't the whole thing. They belonged with Yellow, Blue, Indigo, and Purple back in the darkness. He didn't know what it was and he didn't care. Whatever it was, it was home.

White spots appeared on the black form and the panic just became worse. He didn't understand what was happening. Was home changing? Why was he and Red and all the other colors thrown out? Home was calling them back but he couldn't reach it no matter how hard he tried. He clung to Red and desperately tried to claw through space back to his origin but something was pulling him away. He struggled against its grip but it didn't let up. It just kept pulling and pulling until…

Remus gasped as his eyes snapped open and he returned to reality. Pain shot from the back of his head as he slammed it against the hard concrete floor. His sense of sight flooded back, the vision gone, and he slowly became aware he was in an alleyway. He could feel the concrete against his back and see the brick walls of buildings around him. When had he gotten here? Was this where he collapsed? It always took a few minutes to remember these things after an episode.

Remus flailed his arms but he couldn't tell what they were doing. Mind disoriented, his motor functions weren't completely back yet. His hands felt numb. Anytime they hit something, his mind told him he was flailing too hard and he was hurting himself but he couldn't feel it. He couldn't feel anything except… except…

Oh there he was. That's right. He was with Red. Who was he again? Red… Red… Roman. Roman and Remus. Twins. Now he remembered who he was, he was Remus. He was Remus King, a teenage boy living on the streets of some American city he couldn't recall the name of at the moment. He wasn't Green. He was Remus. Why had he thought he was someone else? It seemed so ridiculous now. He was Remus and always had been.

"Roman," he groaned, putting a hand on his brother's shoulder to try to rouse him. Roman was awkwardly lying on top of him, like he'd thrown himself on top of him when he found him. He probably had. Remus had done the same on numerous occasions. There were no words that could explain how terrifying it was to see your twin, your other half, unconscious and in pain. Knowing they could relieve each other from these horrible illusions was little comfort. It was so easy to forget while in panic.

"Hey, Dukey," Roman murmured, sounding tired. Remus smiled at the nickname as Roman began to pick himself up. He pushed himself to a seated position and rubbed his head. "That was a bad one, wasn't it? I'm sorry I couldn't get here sooner."

Remus tried to sit up but his body protested and he flopped back on the ground again, ignoring the sound the back of his skull made against the concrete. "Don't worry about it, Princey. More pain for me means less for you."

Roman spluttered. "Don't say things like that! We share these stupid visions whether you like it or not. If I hadn't come, you wouldn't have snapped out of it. Do you still want to be trapped in that… that… whatever it is?"

Remus fell silent and Roman let out a long breath. He crawled over, curling up beside his brother on the ground. He made some unintelligible noises of apology but Remus ignored them, taking comfort in holding his twin. His chest rang with that desperate longing he felt in his vision and he pulled his brother into a tight hug. It did little to soothe him but that wasn't anything new. This happened far more often than he'd like.

How many times have they lay on the ground like this, silently comforting the other after an episode? Remus lost count. It'd probably been years since they'd been in an orphanage and it was only then they'd been part of society and it was only in society people had the luxury of things like calendars. He didn't know what time it was, what day it was, what month it was, and he didn't really care. Life was an endless cycle of him and Roman rummaging through back alley trash bins in search of food, waiting for the inevitable collapse of either one of them. Those episodes were what got them kicked out of the shelters each and every time. No one wanted to be around a pair of kids who could collapse into fits at the drop of a hat.

Remus loved his brother though and he knew Roman loved him just as much. Their life was directionless and filled with hungry nights and traumatizing visions but they had each other and that was all that mattered. Life wasn't so bad with Roman at his side.

Remus wasn't sure how long he and Roman were lying in that alleyway, mostly because he wasn't sure when he went down, but the sun began sinking and neither made a move to get up. Remus's body still ached and his head throbbed and Roman had no intention of leaving his brother right now. Right now, they were safe.

Or at least they were until they heard the footsteps.

Remus and Roman sat up with a start, fear seizing the two of them, as a shadow was cast over them. Roman was on his feet in an instant, shielding Remus behind him. Normally, Remus would fight his way to the front but tonight he didn't mind hiding behind his brother. He wasn't quite feeling his usual self.

The figure chuckled and stepped forward, allowing Remus to get a good look at him. He was a tall, slender thing. It looked odd paired with his large, bald head and Remus had to bite his tongue to keep himself from laughing. It really wasn't that funny but it was in his nature. He couldn't help it, he always laughed at the wrong thing. And this was definitely the wrong thing. They were cornered and a stranger was advancing on him.

The man had thick hair despite his baldness. His beard was dark, darker than the clothes he wore. It was a suit of some kind but not the formal kind the twins sometimes saw on mannequins standing in the windows of shops. It had the same coloring but it covered his whole body with no room for opening. Remus didn't really know how to describe it. He'd never seen anything like it but something about it scared him. He didn't like feeling scared.

"Ah. A pair of Osmosians. How rare," the man hummed and Remus cringed, gripping Roman's shoulder fearfully. He didn't like the man's voice. It was so even it almost sounded fake. Like he was speaking with a… a… a snake or a lizard in his mouth. His throat sounded dry and scratchy. Remus didn't like it. It sounded dangerous.

"O-Osmosian?" Roman echoed, confused. He reached a hand back and Remus took it, holding onto it like a lifeline.

The man nodded almost absently. "Yes. My scanner picked you right up."

Remus and Roman exchanged a glance. Their eyes met and Remus saw that Roman's reflected his unease. He disliked this stranger as much as he did.

"So um…" Roman spoke up. "Mister…?"

"Servantis."

"Mister Servantis. If you don't mind, my brother and I will be leaving now. Sorry for the trouble."

Remus shot the man his best smile and quickly hurried past him with Roman in tow. Or at least he tried. A thin hand shot out and grabbed him by the back of his tattered jacket. Remus let out a yelp as he was pulled into the air.

For a moment, panic flooded his system but before he had the chance to lash out and defend himself, he was set back on the ground. In front of Servantis. He gulped and looked up at the man, curious and scared as to what he wanted with him and Roman.

"You two are twins, yes?"

"Y-Yeah…"

"Twin Osmosians, that's something. Osmosians are rare but twins… I wonder what your powers are. You two will be most useful. Come."

"W-What?" Remus stuttered. The man wanted him to go somewhere with him? He didn't like the sound of that. It wasn't like he had anywhere to be but he wasn't stupid. He knew better than to follow a stranger. On the streets, there was freedom. If something bad happened, he could just leave and go somewhere else. If he went with this guy…

Roman was at his side in an instant. He clutched his hand and looked up at Servantis defiantly. "What do you want with us?"

"Oh, not much," Servantis said passively. He turned, drawing a remote from his pocket. "I just want to give you a home."

Servantis hit a button and an explosion of noise filled the alleyway. A portal burst to life before them, rippling and pulsing with noise and color. Roman and Remus flinched back but Servantis stepped into the threshold like he was stepping through a normal door.

He paused and looked over his shoulder. "Coming?"

Against their better judgement, Roman and Remus followed.
