Had thought of this a few days after Domino117 discontinued his story. Found the push to begin to go through with it from Maximum Rhapsody.

Chapter 1:Stranded

Location: Unknown, Somewhere on Earth

Time: Mid-day

The setting is a forest. One occupied with so much trees that it formed sufficient enough shade for anyone undearth trying to avoid the harsh rays of the sun. The weather was so hot that anyone outside would break into a cold sweat in under a few minutes. Though there was only one individual in sight, and it would just so happen that he was underneath one of those trees.

Lying down on his back,unconscious, with his arms spread out wide was a young man, no older than 16. He had combed brown hair, green eyes, slightly pale skin, and had a semi-athletic build. He wore a a black shirt, blue jeans and a green jacket with white stripes on his left sleeve and the number 10 on the right, white socks, and black and white Converse-style shoes. This was Ben Tennyson, world famous superhero .A butterfly would land on top of his nose, causing his eyes to open weakly. Upon taking notice of the butterfly,Ben would immediately shoot up in surprise, causing it to fly away.

As he got up to his feet slowly,he began to scratch his head lightly.

"Ughh, what happened? Said Ben drowsily.

"I remember dropping off Alpha in the Null void, and entering a portal that was supposed to take me back to Bellwood. Though that hardly explains the headache.." Said Ben with squinted eyes. He then began to observe his surroundings and upon taking note of the trees, his eyes widened considerably.

"Ok, I'm pretty sure that the portal was designated to drop me in front of my house. Instead i end up here in some kind of forest." Said Ben with a tone of annoyance. He then knelt on his right knee and took up a flower petal, eyeing it inquisitively.

"Hmm, definitely seems like a sunflower. Means I'm probably back on Earth. Just wondering where exactly." He then got back to his feet and put his hands on his waist.

"Since I'm in a forest, I'm guessing that I must be close to some civilization, so that's a good thing at least." Said Ben as he cupped his left hand under his chin.

"I could probably turn into Jetray to get a better scope of my surroundings. Or Fasttrack to get to a major landmark." Mused Ben.

"Maybe after I contact Gwen and Kevin. Since I'm back on Earth,I might as well call them. They'd probably be worried sick." Mused Ben with a smirk as while he was walking forward,he pushed back the sleeve on his left hand. On it is an object that can grab one's attention easily. A gauntlet-like band with a dark green color scheme. It contains a black rectangular button and wrist couplings, extending up to almost half of the boy's arm or forearm. In the middle was a central core that took the form of a green hourglass symbol with black outlines. This was the Ultimatrix,a device of alien origin that grants it's wearer the ability to transform into various alien species.

Ben then cupped the thumb and index finger of his right hand around the core of the Ultimatrix, and twisted it slightly,causing it to glow a light green light.

"Gwen, Kevin, you guys there?" Asked Ben. All he got in response was static.

"You guys, it's me... Ben" Once again,all that was heard was static.

"That's new. Normally one of them answers almost right away. Maybe I should try Grandpa Max." Reasoned Ben. He twisted the dial once more.

"Grandpa Max? Come in Grandpa. It's me Ben." Not only did the familiar static still remain, but a hologram in the form of a 'DANGER' icon displayed on the core.

"I'm having trouble getting through to him too? I've got a bad feeling about this." Said Ben with a tone of worry.

"Might as well try Azmuth, hopefully he picks up this time." He twisted the dial once more.

"Azmuth, you there?" The 'DANGER' hologram still remained.

"No luck getting through to anyone. Might as well do this the old fashioned way." He then brought his left hand back down to his side and put his right hand into his pocket, bringing out a relatively big green phone. He activated the phone, but what he saw put a look of shock on his face.

"No signal? Oh this is definitely not good." Ben then put the phone back in his pocket. Just as he did this, he had made it out of the forest, and his new surroundings surprised him immediately. He saw what looked like a gigantic wall that covered a large portion of the land in sight, but that wasn't even the most surprising part. He saw what looked like giant, naked, creatures, human in appearance walking through a hole that seemed to be more than ten metres.

"What the heck are those things?" Said a dumbfounded Ben. Just as he said that, he heard loud, blood-curdling screams coming from inside the walls.

"Whatever they are,it looks like they're putting innocent people in danger." Said Ben sternly. He then pushed back his sleeve once more and activated the Ultimatrix. As he did this,a hologram of a humanoid plant creature appeared on the dial. He then twisted the dial clockwise and counter-clock wise, which changed the hologram each time. He would eventually stop on the hologram of a manta-ray like creature.

"It's Hero Time!" Shouted Ben as he raised his right hand above his head and slammed it down on the dial, causing a blinding green light to wash all over him.

A green ball in a green background is seen descending downwards very quickly. The background immediately changes to a light red color, indicating that the green ball has injected itself into the Ben's Bloodstream. Ben is seen in a completely green background but his overall appearance is still very visible. He immediately covers his faces as it becomes more stretched out. His hair disappears completely, leaving his head exposed which only turns red immediately,along with taking a dome like shape. As what seems to be horns begins to grow out of his face, Ben's posture changes into that of a crouching position as a long,red tail grows out from behind him. His outstretched arms go through the final transformation as yellow wings are attached from beneath them to his sides. Ben's new transformation is seen floating above the ground.

As the light dies down,we immediately see an alien that has taken the place of Ben. It's appearance is red, humanoid in nature, alongside that of a manta ray-like alien with green eyes, black outlines on his face, yellow horns extending from his nose, gills underneath his arms, yellow patagia, and two black lightning bolt-like stripes coming down from his shoulders to the symbol of the boys watch on his chest.

"Jetray!" Shouted the Aerophibian,as he took to the sky before flying even further up into the air and then changing direction to far above the place where the hole in the wall remained. Jetray was flying at a moderately low speed, so as to better observe his surroundings. It was safe to that what he saw made him feel uneasy,as several of the giant humans were laying waste to the city within the walls.

"Oh man, this place looks like a wasteland. I just hope not that many people got hurt." Said Jetray worriedly. Almost immediately, he heard the screams of what sounded to be a female. Jetray darted his eyes towards his right and saw one of those giant humans,a 3-4 meter tall giant male human. It had a disproportionately big head and shoulder-length, messy, brown hair with brown eyes. Its body was relatively toned, and it had an angered expression on its face. Inside both of it's hands was a girl that looked to be around Ben's age.

She had fair skin, a slender figure and was of average height. She also had gray eyes and thick black hair that extended past her shoulders. Her hair was parted in the middle and tied in loose pigtails with light-blue hair ties.

She wore what seemed to a brown jacket, opened down the middle and only long enough to reach her ribs. Behind it was a grey shield with two swords crossed together. The symbol was also on the left side of her chest, albeit in a smaller size. She also wore a brown mini skirt, which underneath it had pencil length white pants and knee length brown boots.

The giant human brought the girl slowly towards his mouth,as if about to eat her.

"No!" Shouted Jetray as he flew towards them with blinding speeds. Just as the girl was about to reach the roof of it's mouth,three green laser beams struck the giant in the arm, causing it to yelp in pain and drop the girl.

"Aaaahhhh..." Shouted the girl as she began to fall, only to be picked up from the shoulders by Jetray's feet.

"Huh? What just happened?" Asked the confused girl. However,as soon as her eyes fell on her savior.

"Aaaahhhh!" She screamed while flailing, causing Jetray to drop her on a rooftop nearby. Thankfully, she landed with no inconvenience,as they weren't high up in the air.

"Hey, you shouldn't have squirmed. What if you got hurt?" Said Jetray as he landed in front of her. This however did nothing to alleviate her fears, but rather strengthen them.

"Just stay the hell away from me! Just stay back!" She shouted as she began to back away,a sword pointed towards Jetray. It was then Jetray took note of her waist. On both sides of her waist was medium sized,square shaped, silver colored objects that had brown holsters holding them together. On top of them were spaces, two to be exact that seemed to be where one could sheathe and unsheathe their sword, evident by a sword remaining sheathed on the object at the left side.

"Look,I understand that you're scared and confused, and it's completely fine for you to be." Said Jetray, taking note of her rapidly shaking right hand that held the sword.

"You almost got eaten by a giant, only to get to saved by a flying monster that can talk and shoot laser beams from it's eyes and tail. If I was in your place, I'd totally be thinking I hit myself in the head." Joked Jetray, trying to put the girl at ease. The girl's hand stopped shaking slightly.

"Wh-wh-what a-a-are y..."

"LOOK OUT!" Shouted Jetray as he pushed her off the rooftop before flying downwards and picking her with his feet by the shoulders and flying away from where they once stood,as it was destroyed by the giant human from before. Jetray flew through a few houses that were eating demolished or just barely left standing. He then came to a stop and dropped the girl inside an alley-way. Just as he dropped her, the girl backed up to a wall while sitting down and buried her mouth between her legs.Her body was shaking,her eyes darting from corner to corner in fear as she broke into a nervous sweat.

"Just what exactly are those things?" Asked Jetray.

"T-T-Titans. They're going to kill us all." Said the girl in a low voice, one that most people would find difficult to hear clearly. But most people weren't Jetray.

"Titans? Is that what they're called?' The girl replied with a weak nod.

"Well then, these Titans have put this city to ruins. I can only imagine the people that got hurt." Said a distressed Jetray.

"No, not injured. Worse... killed." Said the girl in the low tone still. Only this one held a great deal of sadness. Jetray's eyes widened briefly, before they narrowed into a cold glare with his teeth gritted.

"No one else is going to die today. Not on my watch." Said Jetray sternly. This caused the girl to look at him with surprise. Jetray took into the air.

"Just stay here, you'll be safe. I've got some Titan butt to kick." Said Jetray indignantly. He then flew away from the girl and passed a few more desolated houses before meeting the Titan from before. The Titan was crouched and seem to be looking at alleyways, most likely in search of the girl.

"Hey ugly!" Shouted Jetray, causing the Titan to stop and turn towards him.

"How about you and I have a proper fight?" As Jetray said this, his eyes and tail began glowing a bright green before laser beams shot out from them at the Titan's forehead, causing it to wince in pain. It then tried to swat Jetray, only for the latter to fly below it,then behind it and shoot another laser beam to the back of it's head. Jetray would then fly all around it's body, sending laser beams to each spot the Titan left unprotected.

"Did I say fight? I meant a one-sided beat down." Taunted Jetray as he shot another laser beam to the back of it's leg, causing it to kneel on it's right leg in pain.

'With my Neuro-shock blasts constantly hitting it, this thing doesn't stand a chance.' Jetray thought to himself triumphantly.

The Titan was pelted with more and more Neuro-shock blasts, causing it to go down on it's knees as it writhed in pain. Standing in a house behind looking carefully was the girl that Jetray saved. She looked at the scene unfold in awe.

'He... He's beating it. And so easily too.'

The Titan was writhing in great pain, unable to stand on it's feet.

"Huh. I thought you'd be knocked out by now. Though if you want some more, I'd be happy to oblige." Said Jetray as he sent even more Neuro-shock blasts across it's body, causing it to groan loudly in pain. After nearly a minute, Jetray ceased his assault, rendering the Titan a heaping mess. But still it remained conscious.

"This thing just doesn't quit."Said an annoyed Jetray as he began to charge his Neuro-shock blasts.

"You have to kill it!" Shouted the girl as she stepped out of her hiding place. This caused Jetray to power down.

"You? What are you doing here? And what do you mean kill it." Asked a confused Jetray.

"You can't knock them out,at least not for long. They'd only heal from their injuries and come back to kill even more people. That's why you have to kill them." Said the girl, displaying more confidence than when Jetray saved her, though her distress was still very much evident.

"Wait? What? No. No,no,no." Began Jetray as he then flew towards her.

"I don't think you understand, ugly monster or not,I don't kill. It's not how I do things. Said Jetray with a frown as he landed in front of her.

"What do you mean you don't kill? You saved me because you saw I was in danger right?" Said the girl in surprise.

"Well, yeah, that's kind of what I do" Said Jetray in a matter of fact tone.

"Well then you'd be saving a lot more people if you killed these things." She reasoned.

"But..."

"I don't know who you are,or what exactly it is you do, but I can tell that you care about people.. These things, these Titans,they aren't people. They're monsters, no... they're worse than monsters." She Began with utmost contempt.

"They're demons. They've killed thousands upon thousands of people and they've been doing so for decades. If you don't kill them, you're only going to let more and more people die. So please, spare them any sympathy,or any mercy, cause they don't deserve it."

For a few seconds, all that heard was the groans from the defeated Titan, struggling to get back to it's feet.

"You better be right about this." Said Jetray in somewhat of a low growl as he took to the air. He was looking down at the Titan's back above it.

"Aim for it's nape. That's their weak spot." Shouted the girl. Jetray looked at her briefly, before looking back at the Titan with a somber look.

"Sorry it had to come to this." Said Jetray sadly. His eyes and tail began glowing even more ferociously than before. In an instant, the Neuro-shock blasts rained down on the Titan's nape in the form of a laser, causing it to scream in pain.Blood splattered on Jetray, and just as quickly as it screamed,it collapsed just as fast, the life leaving it's eyes, and it's mouth wide open.

'That...was awful. I don't think I'm ever going to forget that, but I just hope that I did the right thing.' Thought Jetray with a downcast look on his face. He then flew up into the air and flew in circles for a few seconds causing the blood to evaporate immediately. Once he was cleaned up,he flew back to the ground, and landed in front of the girl.

"Are... are you alright?" Asked the girl.

"Apart from silently praying that this doesn't come back to bite me later, I'm fine. You?" Said Jetray with weakly.

"I am too, thanks to you. You saved my life." Said the girl sincerely.

"Don't worry about it, it's what I do." Said Jetray almost dismissively.

"There's more of these things around, meaning that there's more people who need my help." Said Jetray as he looked into the city, away from the girl.

"Get to safety, when I'm done around here, I'll come back and find you." Ordered Jetray as he took to the skies.

"Wait!" Shouted the girl, stopping Jetray from flying away and looking back at her with a confused look.

"I...I never gave you my name, neither did you give me yours." Said the girl with a faint blush.

"My name is Mina Carolina." Said Mina with a small smile. Jetray's confused face eventually turned into a warm smile.

"Right now, you can call me Jetray, but my real name is Ben." Said Jetray.

"Huh? What do you mean by that?" Asked Mina.

"I'll explain later, but for now just try to stay alive,ok?" Said Jetray almost teasingly before he flew away. Mina's smile eventually reformed,now slightly broader than before.

I didn't initially see myself uploading this chapter until a few days after I published this story,as I was in a foul mood when I did. But now,I feel better and even more motivated than before,so I was able to squeeze out a proper first chapter just hours after publishing the story.

I apologize once again to those who feel this may have been short, but just like I always strive to do, I'll make the upcoming chapters longer.

For those who may already noticed,yes, this chapter was heavily influenced and inspired by Generator Rex: Stuck in the World of Titans. It was written by Man of cartoons and is easily one of the best Generator Rex crossover stories on this site. It's sad however that it no longer gets updated, but it's a great story nonetheless. For those who haven't read it,I encourage you to do just that, you won't regret it.

Constructive Criticism is welcome but not flaming.

Thank you once again for reading this far, means a lot to me. Hope you enjoyed it. Expect chapter 2 soon but until then, have yourself a good one.
