The Stranger

Prologue

The sun was setting over Bellwood and the summer wind blew by. People went about their business as usual. About twenty miles away the military base was slightly busy. The Highbreed invasion was over but that didn't mean they weren't getting ready for another possible invasion. F-35s lifted off and came into a hover as they prepared to test their new weapons. They moved over a bombing range and fired their new missiles. The pilots watched as they hit their targets and exploded into a blue ball. They sucked in the area around them before turning into a gaping hole in the ground. They were designed to implode once they detonated.

Suddenly there was an explosion blowing out the wall in one of the buildings. A man jumped out of the hole carrying an M-4 in hand. His rifle swept to the right and saw nothing. Sweeping to the left he saw three soldiers running at him. Flipping a switch, he fired a three round burst. The bullets ripping into one of the men, and so he fired the gun at the other two men. He looked down as they fell to the ground dead. He stepped into the light and it shined down on his face. Blood was on the side of his face dripping down. He had a scar going over his face, and it shined in the light. His left eye was blue but his right eye was amber in color with a slit pupil. He reached down and cleaned them out of ammo before reaching down and patting their dead bodies. He felt bad for killing them but it was him or them.

He sprinted forward and quickly slammed up against the wall just as a helicopter flew by. He saw the parking lot and he knew it was his chance for freedom. He could escape and disappear away from the hell they had put him through. He looked around making sure it was clear. He ran across the open ground and jumped behind a car. He looked back and saw he was clear and so he looked for a car. He stopped when he saw a custom chopper parked next to a car. He ran over to it and looked down to see the keys were still in it. He looked at the duster that was over the seat. He picked it up and slung the M-4 over his back. He then looked down and checked to see his pistol still holstered. He threw the coat on and climbed on the chopper. He revved the bike and as soon as he did he heard people yelling. Not looking back he accelerated the bike and raced away from the base.

He looked up at the road sign on the side of the road. Hmm Bellwood, sounds like a nice place to hide for now he thought as he drove down the road. He risked a glance over his shoulder and saw that they were locking the base down. He smiled a bit knowing that they hadn't seen him escape on the bike. He relaxed a bit as he drove down the road. He reached up when he felt something in the pocket of the coat. reaching in he pulled out a wad of twenties, a pack of cigarettes, a Zippo, and a cell phone. Tossing the cell phone away he heard it crash on the ground.

He sighed a bit, remembering what had been done to him at that base. What he had been turned into, and the creature they had created just so it could happen. He pushed it away as he saw the glow of the city coming from over the hill. He came to a stop at the hill and looked the small city over. He looked down and saw a back ally near some abandoned factories. He smiled, knowing it was the best place to hide. He drove down the road until he was in front of one of the buildings. His ears twitched a bit at the sound of some rustling coming from in-between the buildings. Shutting the bike off he sighed as he picked up a scent.

"I want all your money" he heard a voice say from behind him.

"You'd be wise to walk away now before you loose your life" he said as he placed a cigarette in his mouth and lighting it.

"Oh yeah, I'm the one with the quills" the voice said to him.

Quills he thought as he looked over his shoulder. He looked as what looked like a man sized rat like alien walk out of the shadows. He arched an eyebrow and looked as the creature's fur seemed to bristle a bit. In a single motion its back arched and he looked as some quills slammed into a wall near him. He looked at it for a few seconds before arching an eyebrow. He looked back at the creature who had a smug look on its face. "What the fuck are you?" he asked.

"Name's Argit, I'm an alien" he says looking at the man.

"Look Argit I really don't have time for you, I'm on the run from the military. You would be wise to walk away now" the man said as he pulled a pistol out and pointed at Argit.

Argit responded by firing his quills at the man. They slammed into his back causing him to growl in pain as he doubled over the handles of the bike. He felt the toxins shoot through his body as his eyes slowly closed. Argit smiled as he walked over to the man. His hands roamed the man's body searching for anything of value. Suddenly a gunshot rang out and his eyes went wide as he staggered backwards. He slammed into a wall and slowly fell down to the ground looking up he saw the man climb off the bike pulling some of the quills out of his back.

"How, the poison knocks people out for hours" he said looking at them man as he came to a stop near him.

"I'm not your normal human" he replied as he shot Argit in the head killing him. "I warned you." He walked over to the bike and sat down on it and let out a sigh. Need a new place to hide now he said in his thoughts as he drove away leaving the dead alien there.

Across town at the Mr. Smoothie people ran away screaming. Kevin Levin flew through the air and slammed into a car. Even though he was covered in metal after adsorbing some it still hurt. He groaned in pain as he looked up into the air to see Seven-Seven hovering in the air. He raised his plasma pistol and shot it at Kevin. Just before it hit Kevin a pink manna shield shot up stopping it. He looked over his shoulder to see the love of his life Gwen standing on the hood of the car. Her eyes glowed pink as she looked down at him.

She quickly chucked two manna balls at Seven-Seven. They hit true and sent him crashing into another car. She looked down to Kevin as he slowly changed back to normal. His shaggy black hair hung to his head as he looked up to Gwen. She knelt down and looked him over to se he was un injured. He looked at her and smiled, his dark brown eyes locked with hers. They were about to kiss when suddenly they heard the sound of a jetpack. They looked to see Seven-Seven raising into the sky looking down at them.

"Where the hell is Ben?" Kevin grumbled as he absorbed some asphalt.

"I don't know but he needs to hurry his ass up" Gwen said as her eyes glowed pink.

They prepared to fight the inter-galactic bounty hunter. They looked as his suit came to life with all his weapons. He chuckled a bit as he locked onto them. In a flash he fired all of them at the same time. Before the blast could hit them Gwen threw up a shield. She looked as much of the plasma blast flew around the shield. She looked to see her shield cracking a bit and she knew it wouldn't last much longer. Kevin saw it too and quickly absorbed the steel of a car and just as the shield shattered he jumped in front of Gwen, taking the full brunt of the blast. He fell to his knees and looked as Gwen caught him. They looked up as Seven-Seven prepared to strike again.

"Those are nice, but mine are bigger" he heard a deep voice say behind him.

Turning around slowly the bounty hunter looked into a pair of four barrel cannons. They fired and the rounds slammed into him sending him flying through the air. He landed on the ground and looked up to see Ultimate Humongasaur walking up to him. Before he could move the beast slammed its fist down on him freezing him in place. His suit was damaged and he couldn't move. Humongasaur smiled before he hit the green and black device on his chest. He turned back into his human form to show an eighteen year old Ben Tennyson.

"I do love doing that" he said with a chuckle as he walked over to join Kevin and Gwen.

"Nice of you to show up, the hell took you so long?" Kevin growled as he worked his arm stretching it.

"I wanted a smoothie" Ben said with a smile as he walked back towards the building. "I want another one now."

Kevin just shook his head and looked as Gwen walked over to his side. "You ok?" he asked giving her a kiss on the cheek.

"Yeah, I'm fine" she said with a smile as she wrapped her arm around his. They looked up as a Plumber ship landed and out came three Plumbers. They took Seven-Seven away. One walked over to them just as Ben walked up to them sucking on a smoothie.

"We are kind of busy right now, we need you three to investigate a murder that happened across town" the Plumber said looking at them.

"A murder, isn't that a job for the local police?" Ben asked looking at him.

"It would be if it was human on human but its human on alien" he replied looking to Ben.

"Who was the victim?" Kevin asked.

"An alien name Argit" he replied as he looked at his wrist reading the report over. "He was shot at point blank with a .45 caliber pistol. He was then executed with the same pistol."

"Argit huh, he probably pissed off the wrong guy. Bout time some one done him in" Kevin said with a shrug as to which he quickly grunted from Gwen elbowing him in the gut.

"We'll get right on it" Gwen said before they walked over to Kevin's car.

"Oh and you'll probably be getting a visit from your country's military" the Plumber said before climbing onto the ship.

"Why is that?" Gwen asked looking at him.

"There was some type of breakout someone or something got out" he said before the ship took off and flew away.

They looked at each other and almost as if on cue two hum-ves pulled up next to their car. They looked as three special forces men came out of the vehicles. One opened a door and they looked as an older man stepped out and they sneered. It was Colonel Rozum, a man they were hoping to never see again after what happened at Area 51. He held a file in his hands and walked over and looked at them.

"Rozum, what a displeasure to see you again" Gwen said looking at him.

"I need your help, all three of yours. We had a breakout at our base twenty miles from here. We believe he may have come here and hid somewhere in this city. " he said as he sat the file down on the hood of Kevin's car. He opened it up and pulled out a picture and handed it to them. They looked at the picture of the man, and two things stuck out to them. The first was the scar across his face, and the second was his amber eye with a slit pupil.

"What do you need us for?" Ben asked looking at him.

"He is far too dangerous for our men, possibly more dangerous than Vilgax" The air force colonel said looking at them.

"What, no one is more dangerous than Vilgax" Ben said before he chuckled a bit. "Except for me."

"This is not a joke Tennyson he's extremely dangerous" Rozum said looking to Ben.

"Um, why do you want him back?" Gwen asked still looking at the picture. She couldn't place her finger on it but there was something about this man that she could see in his eyes. He didn't look bad, well not as bad as the good Cornel was leading on to be.

"That's classified" he quickly answered making her look at him.

"Then we shouldn't help" Kevin replied.

"Look it's even beyond the president, if I tell you I will be shot. Find him and bring him back dead or alive" Rozum said before he grot back into the hum-ve and rode away.

Gwen and Kevin looked back down to the picture. This man seemed like he could be a very serious threat. Kevin seemed to look at the picture and looking at the man he seemed to see something in this man. Something that reminded him of himself. Gwen looked up at Kevin and passes the picture to him before picking up the file. She looked it over, skimming over everything until her eyes hit something. His age, he was eighteen going on nineteen, he was as old as the three of them.

"Oh my god, he's only eighteen, going on nineteen" she said looking to Kevin

"Hmm, Mathew Smith, eighteen special forces, and he's been in jail since a month before the Highbreed invasion" Kevin said looking over the file as well.

"What does it matter, he's just another bad guy, one we will take down just like all the others" Ben said in an arrogant tone causing both Gwen and Kevin to look at him.

"First lets go see if we can't find any clues as to who murdered Argit" Gwen said looking over to both of them.

"Right a murder and a dangerous man on the loose" Ben said as she scrolled through his Ultimatrix. "Looks like a job for Wildmutt" he said as he slammed his hand down on it and in a green flash he became the alien. The hunt was on, and the three of them took off in the direction of Argit's death.
