DISCLAIMER: I am making quite a few changes to the story. There are a few reasons. His full name will be Benjamin James Tennyson. Also, he will be fifteen (you'll find out why later on in the story). There will also be twelve aliens, no Gwen or Max (or will there?), the character will be a street punk, and will have a strange past. I'll try to stay true to the original Ben 10, but there will be differences. I'm also going to use both original and Alien Force aliens. If you have any complaints, send them to me. Finally, I might make a few time and date errors, but just ignore them. BTW, this takes place in late 2006.
September 8, 2006. It was a cold, dark day with gloomy weather. At 9:30 at night, no one would notice the teenager sitting in the dark alley between a gas station and an apartment building. This boy was Benjamin James Tennyson, though most of his buddies called him Ben. By 'buddies', I mean the other guys and kids who either ran away or have no home. Ben was fifteen, born on August 12, 1991. He couldn't remember his life, parents, nothing. He had a scar on his forehead, which he figured gave him amnesia, explaining his blank memory of his past. That will be delved into later. For now, let's talk about this boy and the impact he will have in the superhero community.
Now, Ben liked walking in Central Park, even in cold weather. He normally wore a black shirt, jeans, white sneakers, and a green light jacket with a black patch with the number ten on the left side. He had green eyes and brown hair that was about medium-long, about to his midneck in a spiky manner ((think Kevin from the first series)). Anyway, Ben was walking in Central Park, thinking about the most recent NYC events, including Spider-Man and the Ultimates fighting Rhino and Electro on the pier in lower Manhattan. Ben was a fan of the superheroes, alright. His favorites were Captain America and Reed Richards, the former for going from wimp to supersoldier, and the latter for his intellect. As he was walking, Ben reached into his pocket to feel his three most valuable items, a switchblade with his initials on it, a black Zippo lighter with an image of the Guns N' Roses 'Appetite For Destruction' cross with the band members' skulls on it, and an iPod he (admittedly) stole from a shop. He wasn't a thief, he was a bored teenager. After that, he looked up at the night sky, which he liked to do. He saw a shooting star, and said "Lucky me." Then the star did something impossible: It completely changed direction.
The rock headed straight for Ben. He managed to jump out of the way before the meteorite crashed into the place where he was just standing. Ben was gasping and trying not to have a heart attack. After catching his breath, he looked at the meteor. He almost walked away when he remembered how much meteor chunks are worth, especially one this size (about as big as a medicine ball). Ben hopped into the crater and walked toward the rock. When he got close, another surprise popped up: the meteor retracted its top half into the rest of its body, turning into a half sphere. Ben then noticed that the sphere was metal. Then he saw a weird green glow come from the half-sphere. He walked closer and saw what appeared to be a thick black watch.
The face was an hourglass shape, green on the hourglass, grey on the two shapes that made it a circle. The band was about 3 to 5 inches long and had what appeared to be a small green button on one side. When Ben impulsively reached for it, the watch seemed to jump up, split apart next to the face, and attach itself to his wrist. The reaction was instantaneous: Ben flipped out. He hopped around, tugging at the watch to take it off. He bit it, he pulled, he hit it against rocks. He even tried to use his switchblade to cut it off. After ten minutes, Ben gave up and sat under a tree playing with the extraterrestrial device. He checked the face and saw no time. It's an alien device, of course it doesn't tell time, he scolded himself. He then remembered the button on the side, which was facing him. He pushed it to see what would happen.
The face of the watch popped up about an inch after Ben pushed the button. He looked at the face. He saw that the two angles that made the narrow points of the hourglass converge with each other to turn the hourglass into a green diamond. In the middle of the diamond appeared a silhouette. The silhouette appeared to be that of a tall guy with large feet, thin hips, and a spiky hairdo. Ben put his finger on the face, and then pushed it back down. There was a bright green flash, and Ben transformed. There was a strange tingling sensation, followed by his skin turning into a green plant-like substance. Then he felt his bones and muscles disappear. Finally, his head started to become pointy and tall. The face of the watch appeared on his chest, with the hourglass colored white and the other two shapes were colored black. In a matter of about two seconds, Ben had gone from street punk to powered hero. He had become... "SWAMPFIRE!"
Nick Fury was examining the monitor. He had heard about the meteor that had been heading into the atmosphere. He was unconcerned. That is, he was unconcerned. Until his science team showed him that the meteor had completely changed direction and crashed into Central Park. Fury had automatically assumed the worst :alien hostile. He turned to the officer behind him. "Get the Ultimates ready and send a squad out there. We might have a little green problem."
