(A/N: This is something that's been in the works for a number of years. I first came up with the idea when I started watching all these reruns of "Teen Titans" and new episodes of "Ben 10: Alien Force/Ultimate Alien". Then I completely forgot about it until I started watching these shows again.

Because the "Alien Force/Ultimate Alien" arcs were the ones I grew up on, Ben and his team will be how they were during that time. Meaning Ben will shout out the names of his aliens and there's most likely not going to be any mention of characters introduced in "Omniverse" since I barely got halfway through season one before I started watching other stuff. However, I will include one element that's usually associated with "Omniverse", but it'll most likely be just at the beginning and maybe mentioned or referenced later on as this progresses.

Originally when I first thought up this whole thing up Titans East and a few villains from both franchises were going to be apart of it, but after my "Scooby-Doo/Teen Titans" crossover I decided not to. So, unlike with my other two crossovers I'm not going to go too crazy with it, but knowing me I might end up throwing in a random element or two just for fun or to add a little comic relief because there's probably going to be some darker elements in this from time to time. A lot of the themes and elements in this takes inspiration from the songs "Monster" and "Hero", both of which are by the band Skillet.

Before I forget, because "Alien Force/Ultimate Alien" is the era I'm most familiar with, Ben will be using the Ultimatrix instead of the Omnitrix he got at the end of series. It's mainly because I like the look of the Ultimatrix better than the Omnitrix (for whatever reason). I hope you guys are cool with this.)

Bellwood - 10:30 PM

Ben, Gwen and Kevin were inside the storage unit they used as almost like a headquarters. Gwen was typing on her computer, trying to find evidence of something they were recently informed of.

The information they were given was from none other than Reinrassig III, the Supreme leader of the Highbreed. According to him, a specialized messenger android, code named Angelos, he had ordered to be sent to them had gone off course and landed somewhere on Earth. Gwen has been able to narrow its location to the United States, the western half of the States to be specific.

In the meantime, Kevin was polishing his car from head to toe. Ben was sitting on the hood of his car, while drinking a raspberry and beet smoothie. Both had grown bored waiting for her to finish her research hours ago.

After just a few more minutes of typing and research, Gwen exclaimed, "I found it!" Ben almost spilled his smoothie and Kevin almost banged his head on a table as he stood up.

"What did you find, Gwen?" Ben asked as he and Kevin came up to her.

"I was able to hack into the thousands of satellites currently in orbit, owned by both governments around the world and by the Plumbers. I searched through images taken in the past few months and found an object the size of the android Reinrassig told us about. After a simple equation, I was able to pinpoint the exact area where it landed," she explained.

"So, where is it?" Kevin asked.

"After looking over the area I pinpointed on a satellite map of the States, I found that it most likely landed in Jump City, California," she answered. She then told something interesting, "On a hunch, I looked up recent events in that city and found that two weeks ago, a group of heroes called the Teen Titans battled 'a mysterious white monster'." She showed them an image of the so-called 'white monster', "Look familiar?"

The image was of an all white monster-like creature with black marks on its face and red eyes. The monster looked exactly like the description and blueprints given to them by Reinrassig. It wasn't too difficult to determine the size of it, they had seen and fought more than enough Highbreed to know that it was the exact size of the average Highbreed. There was no doubt that this monster was the android they were looking for.

Ben looked at Kevin with a serious look on his face, "Fire up the Rust Bucket, we're going to Jump City."

Jump City, California - 6:00 AM

The sun hadn't yet fully risen over the horizon, but Robin enjoyed waking up early so that he had a chance to catch up on his training. In the fifteen minutes he had been awake he took a shower, put on his costume and gelled his hair to make it spiky.

He was on his way to the kitchen to get a glass of water. Once he made it down the hallway to the living room/kitchen area, he was surprised to see the TV on and the channels changing, indicating someone other than him was awake.

He walked over to the sofa and was shocked to see that it was Beast Boy who was awake. Or should he say half-awake; he could see visible dark rings underneath his friend and teammate's eyes.

"Beast Boy? What are you doing up this early?" he asked. "Normally, you sleep in as late as possible."

"I haven't been able to sleep well lately," he replied quietly and sleepily.

"Does it have to do with Terra or you know?" he asked carefully.

"No, I've been able to accept that Terra doesn't want to come back to us, if that girl really was her," he answered, almost in a reassuring way.

"That's... very mature of you, I'm impressed. So, have you been checking on him lately?" he questioned, his tone turning serious.

He knew exactly who he was referring to, "He was doing some exercises when I gave him his breakfast yesterday, but he started to look kind of sluggish later on."

He rubbed his chin, "I'm not sure if that's an improvement or if it's something we should keep an eye on."

"Well, don't ask me," he shrugged, "I wouldn't know."

He continued to flip through the channels and didn't even notice the other Titans walk into the room. He didn't even notice Cyborg coming over to sit next to him, causing the couch to move slightly.

Cyborg fake coughed, trying to get his attention, but he didn't even blink. He coughed again, but still nothing.

"Uh, Beast Boy?" he nudged his shoulder to get his attention.

"Yeah?" he finally acknowledged his close friend.

"Have you been sleeping at all lately?" he asked.

"No, I guess I'm just worried about you-know-who," he admitted. "He just didn't look very well yesterday."

"Why? Robin said you told him he was exercising when you gave him his breakfast," he pointed out.

"Yeah, but he looked kind of sick when I gave him his dinner," he told him.

Starfire overheard their conversation and asked, "Beast Boy, were you able to acquire any information about him?"

He put a finger on his chin, "Uh, if you mean that we sometimes have conversations then, yeah. He tells me if he's feeling good or not and sometimes we talk about our hobbies and interests and things like that." He continued to tell them about some of the things they talk about and information he was told.

Beast Boy, holding a plate full of food in one hand and a bottle of water in the other, walked into a room. The room was more or less one-third free space and the other two-thirds was a containment quarter.

The containment quarter was practically its own little room. It was white with some stains here and there that weren't there a week ago. The room had a cot and a door leading to a small bathroom. Protecting both the person inside and the people outside was a think glass panel with a small sliding glass door to get food and dishes in and out.

Both Beast Boy and who was inside walked up to the glass panel. He opened the sliding door and handed him his food and the bottle.

Not knowing what else to do, he just stood there awkwardly. He noticed that their 'guest' kept placing a hand over his stomach and looked pale.

"Hey, dude, uh, are you okay?" he asked.

"I feel very nauseated," he answered, somewhat sickly.

"Try drinking some water," he tried to help.

He opened the bottle and drank some water. He drank only a small sip when he suddenly dropped it and rushed to the bathroom with a hand over his mouth. The water spilled out of the bottle like rain going through a gutter and formed a large puddle on the floor.

He came back fifteen minutes later, looking paler and sicker than before. It wasn't that he looked a lot worse than earlier that worried him, but the blood he noticed pooling in the corners of his mouth.

"Uh, you have blood in the corners of your mouth," he wiped the sides of his mouth to show where it was.

He copied his movements and grimaced at the blue smears on his cyan fingers. He wiped his fingers on his black pants with angered expression on his face, "Wonderful."

Instead of eating the rest of his food, he took out a dark red music player and black headphones. He put one headphone over his pointed ear while the other was behind his other ear and looked through his list of songs.

"Hey," Beast Boy spoke, getting his attention, "you didn't steal those, did you?"

He shook his head, "No, I found them lying in the grass at a park."

"A park?" he repeated, now a little suspicious.

"I like going to the park to relax, especially when my friends start to argue over mediocre topics. I typically like to be in areas where no one would go to. That way I don't have to worry about scaring people or worry about them contacting the police," he explained.

He picked a song and unplugged his headphones so that he can listen too. The song "In Too Deep" by Sum-41 echoed throughout the entire room. He softly sang along to the chorus.

"'Cause I'm in too deep, and I'm trying to keep

Up above in my head, instead of going under

'Cause I'm in too deep, and I'm trying to keep

Up above in my head, instead of going under

Instead of going under…"

Beast Boy was mesmerized by this, "Dude, I didn't know you could sing."

He shrugged, "It's something I picked up after listening to these songs over and over. They help me improve my vocabulary as well as help me keep my mind off of... events."

He was almost sorry to ask, but did anyway, "What kind of 'events'?"

Not wanting to give too much information about himself, he told him about a traumatic event, whose anniversary was coming up very shortly, "Eight years ago, I was held prisoner at a top secret government facility. The cell they kept me in was full of water and I was only let out of it once a week for cleaning. The General kept asking me about an invasion and what my plans for Earth were. No matter what I said, he didn't believe me and told me that I would rot in that cell unless I told them what they wanted to know."

"Whoa... what happened next?" he asked, very intrigued.

He continued with his story, "After I couldn't give them what they wanted, they started to give me less food and cleaned my cell less often than before. One day, I got a new guard assigned to me. He was a Sergeant and couldn't have been any older than twenty-two. He told me he wasn't just a regular guard, but was also a negotiator and that I could trust him. He told me his name and I told him mine."

"Oh, man," he gasped. "So, what happened next?"

"I was getting to that," he drank a little water from what little was left in the water bottle he spilled. "Now, where was I?"

"You were at the part where you and the Sergeant introduced each other," he reminded him.

"Oh, right," he got back on topic with his story. "He said that as long as he was around, nothing would happen to me, that all they wanted was information on who I was and where I came from. I went silent and said to him, 'I am scared. I fear they want more than simply personal information.' I told him how I lost my entire family and how I almost died seven times within the span of eight months."

This was something he could sympathize with as he lost his family too and he was also used as a lab rat. Though, from the sound of it, it sounded like he had a much rougher life than he did.

He went on to finish his story, "He went quiet, before he said to me, 'I'm going to get you out of here. I'll be back.' He told the General I wasn't feeling well and had to be immediately taken out of the cell. He allowed it and when I got out of it, the Sergeant grabbed my arm and we made a beeline for the back door. We ran through a laboratory and out the door, he grabbed a pair of wire cutters on the way out. I can still hear the sounds of their boots and their canines barking at us. He started to cut at the fence surrounding the building, both of us were shaking the entire time. Just as they approached, he finally made a hole big enough for me to slip through."

"W-What happened to him?" he was almost sorry to ask this and maybe he should have been.

"He... didn't make it. I didn't see anything, but I heard... a sound of thunder," he replied, grief stricken.

When the story was finally finished, he silently left the room. He watched him leave with a blank yet saddened look on his face. He plugged his headphones back in, put the other headphone over his ear and looked through his songs. It didn't take him long before he found the right one, "Vampires Will Never Hurt You" by My Chemical Romance. Just like before, he softly sang along to the song.

The rest of the Titans were in absolute shock when Beast Boy finished his story. Never in a million years would any of them imagine that a villain could have such a tragic life. Though, maybe they shouldn't be that surprised.

The typical stereotype of people with tragic backstories is that they will become heroes to prevent what happened to them from happening to others. However, there are some who believe that others deserve to suffer as punishment for society turning them away. Or it could be to show them that life isn't fair and they could lose everything in a matter of seconds.

"And I thought I had a bad life," Cyborg commented.

"I thought losing your parents would be the most tragic thing that could to someone, but losing your entire family is just crazy," Robin sounded angry.

"Not to mention almost losing your life as many times as he did," Raven added.

"It must have a very terrifying experience for him to have gone through at such a young age," Starfire brought her now-folded hands close to her mouth.

Ben, Gwen and Kevin arrived in Jump City between midnight and one in the morning. Normally, travelling across the country would have taken them much longer, but the Rust Bucket was a lot faster than the average jet on Earth.

They spent the next six to seven hours since then to trace the last known location of the android. There was a bit of a problem though, the android hadn't been seen since the article Gwen found had been published. Also, she can't track it because she can only trace someone or something through their mana and, unfortunately, androids have no mana because they're not alive.

Ben then remembered something, "Didn't Reiny say that it was created with the powers of an Osmosian in mind?"

Kevin wasn't sure where he was going with this. "Yeah, so?"

"So, that means it probably has the ability to absorb anything it touches, just like you can," he stated.

"I checked the blueprints given to us on the way here and found that it can blend into the surroundings of whatever it absorbs," she informed.

"I think I see where you're going with this, but how are we going to find it if it can hide like a chameleon?" he asked.

"Easy, we let Wildmutt do all the work," he smirked confidently.

He activated the Ultimatrix and turned the black and green face, searching for the said alien. It didn't take him long before he finally found his desired alien. He slammed his palm onto the face and was engulfed in a green light.

Seconds later, the light dimmed and revealed a familiar orange, eyeball-less, canine-like alien. He let out a howl very similar to that of a wolf and a lion.

He used his enhanced senses to sonar the surrounding area, until he finally found something. It was faint, but it was something and he wanted to check it out. He growled and snarled at them before he took off.

"Ben, wait!" she shouted at him as he ran off.

"Tennyson!" he also shouted at him.

She used her mana manipulation powers to create steps so that she and Kevin could follow him. They didn't have to follow him for very long. They followed him to a construction site where it looked like a battle had taken place recently.

Almost as soon as they caught up to him, Kevin remarked, "You could've gone Ultimate and told us where to go, you know?"

Wildmutt whined and transformed back into Ben, "Sorry, I didn't want to attract any attention by going Ultimate."

"And a regular Vulpimancer wouldn't?" he gibed.

He rubbed the back of his head and laughed in embarrassment, "Yeah, good point."

Meanwhile, she was using her powers to know exactly what happened there. She found that the activity on that site had taken place two weeks prior and some of it had been cleaned up.

"Guys," she started, getting their attention, "we're on the right trail."

"Where to next?" Ben asked.

"The trail is faint," her eyes glowed pink, indicating her powers, "but I think I can follow it."

"Wait, I thought you couldn't track anything that's not alive?" Kevin questioned.

"I'm not tracking the android, I'm tracking whomever was fighting it," she replied.

She closed her eyes and used her levitation to start meditating. She put her mana in sync with the lingering mana of the people who found it to see where it went.

She opened her eyes and set her feet on the ground, then informed them of what she saw, "The fight started here, then led to the sewers, then continued down a street several blocks away, then at a factory or possibly a foundry, but that's all I could see. I couldn't get any details about the fight, just the places where it took place."

"Well, then I guess we should start at the last place the battle took place," Ben stated.

"That factory?" Kevin questioned, somewhat rudely. "There's only one problem with that: there's probably dozens of factories in this city? How will we find the right one?"

"I'm pretty sure she said that it could've been a foundry," he reminded.

"I remember seeing the word 'recycle' in front of the building," she told them. She put a finger on her chin, "If that's the case then it's probably a recycling plant."

"Okay, so that narrows down the search, but how are we going to find it?" Ben asked.

"We could get our rides out of the Rust Bucket," Kevin suggested.

"Or I could go Wildmutt again," he held up the Ultimatrix and started to look through it.

"We're not following that alien mutt again, Tennyson," he deadpanned.

While they argued, Gwen was busy trying to find more details about the location of the recycling plant by concentrating on her powers. It took her a couple minutes but she finally found it, "Got it. It's a quarter-mile from here, just off of McDuffie and Murakami."

They surrounded her and she created a bed of mana and levitated them back to their ship. Kevin opened the hatch and they went inside to the cargo hold where their cars were. They got into Kevin's car and drove off in the direction of the plant.

It took less than ten minutes for them to drive to it. Once there it was decided it was probably best to suit up before going inside. Only the Lord knows what could potentially be waiting for them.

"Which alien are you gonna go with?" Kevin asked Ben as he absorbed the metal from the fence surrounding the place.

"Well, for some reason, I'm feeling kind of nostalgic," he replied with a confident smile.

He activated the Ultimatrix and searched through it for some of the original aliens. It didn't take him long before he found the right one, who just happens to be one of his favorites. He slammed his palm on the face and was once again engulfed in the green light. The light faded away to reveal a familiar red, four-armed humanoid alien.

"Four Arms!" he exclaimed. He looked down at himself and smiled, "Wasn't even sure he was still in there!"

Kevin opened the gates by slicing open the chains holding them together with his sickle shaped hand. He turned his hand back to normal and they walked up the building. Surprisingly, it was unlocked, so all Four Arms had to do was push the doors open.

They walked inside and made sure to be cautious. Gwen clenched her fists and concentrated her mana into her palms, ready for anything. As said before, only the Lord knows what could potentially be waiting for them.

Almost as soon as they walked in and looked around a little bit, she noticed a camera above them. The blinking red light told her it was on and recording them.

"Camera Oblitera!" she cast her spell and deactivated it.

Sometime after they took in the story they were told, all five Titans sat on the sofa and watched TV. Once again, Beast Boy kept flipping through the channels, greatly annoying his friends who just wanted to watch something. It wasn't until Robin spotted something on one of the channels that he stopped.

"Hey, can you go back to that news channel you just passed?" he asked.

"Sure," he replied quietly and almost unemotional. He changed it back just as the news started talking.

"America, you are watching the "Harangue Nation". First off, there's good news for the citizens of Bellwood," he said. "The teenage menace known as Ben Tennyson has left the city, probably off to cause more destruction. Fingers crossed he never comes back!"

"Ben Tennyson? Isn't he the guy who uses those aliens to save people?" Cyborg questioned.

"Obviously there are people who don't believe he's a good person," Raven stated.

"Hero or not, that doesn't give him the right to break any laws," Robin asserted.

"And we never break a few laws when we go out to stop a robbery or break in?" Beast Boy asked questionably and matter-of-factly.

"While I believe his use of various species and reckless nature could potentially be dangerous, I do believe it is all for the sake of mankind," Starfire voiced her thoughts.

Their conversation was cut short by the crime alarm going off. Robin got up from the sofa and started typing on the computer. The TV screen was replaced by video feed from several streets and the recycling plant.

The feed from the streets showed an orange, canine-like creature running towards the construction site they were at just two weeks prior. The other showed two people, a man and woman, entering the building with a muscular red humanoid with four arms.

There was something unusual about the man and woman. The man was covered in what looked to be steel and the woman's hands were glowing pink.

"A break in? What could they be looking for?" Robin questioned.

"Who cares? They're obviously up to no good, we gotta take 'em down!" Cyborg asserted.

The woman noticed the camera they were looking through. She raised one of her hands and the feed suddenly pixelated, indicating that it had been destroyed or cut off.

This seemed to help him prove his point, "See?"

"But what about that orange dog thingy?" Beast Boy asked.

"I could not see it clearly, however, I believe the canine creature may be a Vulpimancer," Starfire spoke. "The other is likely a Tetramand."

The others didn't know what she was talking about, though she clearly had knowledge about the creatures caught on camera. They needed as much important as possible on the creatures in the video feed.

"Star, what can you tell us about those creatures?" her boyfriend asked.

"Vulpimancers are a vicious animalistic species from the planet Vulpin. They are not known to be friendly, not even with their own kind. Tetramands are a fairly aggressive race from the planet Khoros. They are great warriors who favor violence over peace," she informed. "That is all I know."

"That's alright, Star," he assured.

The only further proved his point, "If they're as dangerous as she says then it's our job to take them down."

"Fine," he complied, "we'll go to the recycling plant first, then deal with the Vulpimancer later."

Cyborg, Starfire and Beast Boy were the first ones to leave the room. Robin was about to follow them, but Raven grabbed his arm, holding him back.

"Robin, wait," she almost sounded a little concerned.

"What's wrong?" he asked.

"I think that girl used a spell to disable the camera," she told him.

"Spell? As in magic?" he questioned.

"It's nothing like the magic I've seen on Azarath, it's... different," she stated.

He had no response to this and before anything more could be said, Cyborg called out to them. They left the room to join up with their teammates for this mission.

The alarm still rang throughout the entire Tower in every room. And in one of these rooms the alarm gave their "guest" all but a headache. Though the dizzying, throbbing pain in his head was dulled out by the overwhelming burning pain in his abdomen.

He laid on his back on his cot and had his hands on his stomach, though it did little to help. He stared up at the ceiling, though he had difficulty making out what little could be there; his entire world was spinning.

(A/N: Well, this only took a few days to write and finish. That's what happens when I'm happy to get things started and done.

I'm sorry if everyone seems a little OCC, I tried my absolute best. Speaking of which, can you guess who their "guest" is? (*hint* *see I.R.*) (I.R. is an abbreviation by the way, you have to figure it out on your own)

This story is based on two theories I came up with about both shows. The first theory is that a certain racist in "Teen Titans" was evil all along. The second theory is that an entire race of (former) racists in "Ben 10" were never evil to begin with. I won't ramble on about them right now, but there is a lot of evidence to support them.

One more thing: chapter two will be real soon. I've already gotten started.)
