Hey everyone, TheKingHHH100 here! Today not only I'm posting my first multi-chaptered story, but also my first ever crossover! And it's between two things I haven't written about yet: Ed, Edd n Eddy and Ben 10. This will likely be a two-shot. I'm planning on doing a whole series about this concept, but first I'm posting this story as a sort of test, mostly to see if I can get the characters right. So tell me what you think of it.

Anyways, hope you enjoy the story and feedback is always welcome. On to the story!

Ed, Edd n Eddy in "OmnitrixED". An Ed, Edd n Eddy and Ben 10 Crossover.

In outer space, two ships are battling and one of them is commanded by a squid-like alien. This alien's name is Vilgax, conqueror of worlds, and he is going after what's in the other ship: the Omnitrix, the most powerful tool in the entire universe. As his ship fired laser beams at the other ship, the fire was returned and it hit his ship's hull, making the entire ship shake.

"We've been attacked, 20 %, we lose power." His robot lieutenant told him. Vilgax clenched his teeth.

"Keep on attacking. You have to destroy the ship so that the Omnitrix is in my possession." Vilgax ordered. He had come too far to be denied. He would get the Omnitrix, or else…

His ship fired a large blast from its main cannon and destroyed the other's ship stern. "Their propulsion systems have been destroyed." His lieutenant reported.

"Prepare to aboard. I want the Omnitrix, now!" Vilgax said. As he said that, the smaller ship approached them and started glowing.

"They have started self-destruction mode." His lieutenant said. Just after that, the small ship exploded, destroying the top part of his ship.

Vilgax was shaken by the explosion but managed to protect himself from the full blast behind some of his drones. As he moved from the pile of drones, he could see that most of his robot lieutenants were damaged or destroyed, and that the front part of the smaller ship hadn't exploded, instead it was firing what appeared to be a missile but in other direction. The missile then opened to shoot a small bluish container towards the closest planet. Vilgax knew what was inside.

"Only I can have the Omnitrix…" Vilgax stated. He would go to that blue planet and retrieve the Omnitrix, even if he had to take it from someone else's death body.

Meanwhile on Earth:

In this planet there is a town known as Peach Creek. Where we go to the junkyard where we see three boys known by everyone as The Eds, since all their three names started with that one: Ed, the tallest and strongest of the three but also the less brightest of the three, Edd, also known as 'Double D', the smartest of the three but also the weakest, and Eddy, their leader and the smuggest of the three who planned all their scams but also the shortest and short tempered. Right now, they were digging around the trash for parts to build their next scam.

Ed had picked up a toothbrush. He went to Eddy who was just walking around and said, "I found a tooth brush Eddy!"

Double D went up to Ed and said, "Ed, put that down. Who knows where that was?"

"Stinky hat" Ed responded.

"What did you say?" Double D asked with anger.

"Stinky hat."

Eddy was getting tired of this. His friends argued for the silliest things, like that time Ed had that stinky chunk of cheese on his jacket, since Double D was a germ phobic-obsessive cleaner and Ed was… well let's say he was just Ed. As he continued walking, something caught his sight in the sky, it seemed something really bright was falling from it. A shooting star? In the middle of the day? And it was coming their way?

As he was about to wish for money, the star went past them, knocking over a pile of garbage that was around onto Eddy, and crashed in the middle of the junkyard, shaking the entire place with the explosion. Ed and Double D quickly stopped arguing and went to check on their friend. "Eddy, are you okay?" Double D asked him as Ed removed a metallic cylinder that was above Eddy's head.

Eddy got up dizzy from being hit in the head. "I'm seeing stars… No, wait. Just one shooting star!" Eddy exclaimed as he recovered. "A comet! I'm rich!" Eddy exclaimed as he started running towards the area were what he thought was a comet had fall.

"Eddy! Wait!" Double D exclaimed as he and Ed ran after him. When they arrived at the area where the 'star' had fall, they saw it had made a huge crater on the ground. In the middle of the crater was what appeared to be some kind of pod of a metallic color, though surrounded by a red aura of heat since it had cross the atmosphere.

"Oh my! According to my calculations, taking the direction, the speed and the impact from this unidentified object, it seems that it actually has come from space!" Double D exclaimed with emotion.

"This looks like one of the escape pod from my Galaxy Wars comic!" Ed exclaimed before Eddy jumped onto his head and closed his mouth with his hand.

"You mean this is an alien ship? Oh my God! We're gonna be rich!" Eddy said thinking about how much money he could sell that thing for…

"Actually gentlemen, even though there seems to be some piece of technology, it doesn't necessary mean its alien origin, it may be some kind of satellite…" Double D said as he took a magnifying glass and examined the object in the crater a little bit closer. However, Eddy interrupted him by jumping on his back and making him fall, using him as a surfboard to the center of the crater. Ed followed by tripping and falling into the crater too.

Eddy landed flawlessly, with poor Double D buried into the ground, followed by Ed falling face first (not that it did hurt him too much). "I'm rich! I'm rich!" Eddy went running straight to the pod, however, when he touched it he burned his hand causing him to scream in pain.

Double D got up, spitting dirt as he did, and exclaimed, "Eddy! No! Don't touch it, it still must be hot from crossing the Earth's atmosphere!"

"Geez Sockhead, thanks for the advice! Stupid thing!" Eddy angrily said as he kicked the pod, however that only made him hurt his feet. "Ow! This thing is useless!"

As Eddy said that, the pond opened scaring him and making him jump to the ground screaming. "ALIENS!"

Double D hide behind Ed scared, while the tallest Ed just looked on with an excited face, expecting an alien to come out of it. However, nothing happened. Eddy got up and looked at the pod: it was empty. "Hey, there's nothing here! Man, what a waste of time-" however a green glow started coming out of the pod.

Eddy was ready to jump again, however he looked inside the pod and saw what was glowing: something similar to a watch. The thing was black and grey, with a grey dial in the middle, like a watch face, that has a green hourglass shape where the faceplate should be. Eddy was amazed by it. "Hey guys, there seems to be some kind of… watch thing in here."

"A watch? What would a watch be doing in space?" Double D asked.

"I don't know, maybe is an astronauts' watch? The important thing is that is all mine!" Eddy exclaimed as he went to grab it.

"Eddy, be careful!" Double D tried to advert him, however, as Eddy was about to grab it, the watch jumped to his arm like it had gained life and wrapped around his wrist, glowing an intense green as it did. It finally settled on Eddy's arm and stopped glowing. When it was done, it seemed to be fused to his arm.

"Aaaaaaah! Take it off! Take it off!" Eddy exclaimed in horror as he shook his arm, the watch however didn't even move. He dropped to the floor and tried to wrestle the watch out using his legs and feet, to no avail.

"Eddy are you okay?" Double D asked his friend.

"Of course not Sockhead! This stupid thing doesn't come off me!" Eddy angrily exclaimed. "Ed! Get it off!"

"At your services Eddy!" Ed exclaimed as he grabbed Eddy by the collar of his shirt, then grabbed the 'watch' on his wrist with his other hand and tried his best to pull it off from him. With Ed's incredible strength, he was able to pull the 'watch' and even stretch it a bit, but it wouldn't get out of Eddy's wrist. "It… doesn't… come… off." He said finally giving up after many tries.

"Umm… this reminds me of that time Ed got his finger stuck in that Ship in a Bottle." Double D said remembering that event. It had taken them the entire day to finally take Ed's finger out of that bottle. "Maybe some soap will do the trick?"

"SOAP IS BAD FOR ED!" Ed shouted.

"Shut up Lumpy! And get us out of this crater!" Eddy told him. Ed quickly grabbed Eddy and Double D and walked out of the crater.

After that they tried many ways of taking that 'watch' out of Eddy's wrist: some soap (much to Ed's dismay) and some oil, neither of those worked, then taking it out with a crowbar, which also didn't work as the crowbar broke in two, and their last attempt was to tie Eddy to a tree (minus the arm with the watch) and tie the watch using a different rope which was tied to Ed, then Ed ran as fast as he could to try to take the watch out, that ultimately didn't work as the tree came crashing down onto Eddy and Ed.

Finally they returned to the junkyard in defeat, looking for other possible ways to try and take that watch out of Eddy. Suddenly, Ed (in a rare moment of his) had an idea. "Guys! I know, what if we use a hacksaw?"

"What are you stupid?! I'm not cutting my arm off you idiot!" Eddy shouted angrily.

"Oh boy, the irony…" Double D said still remembering when Ed had his finger stuck and what Eddy had said in that situation.

"I hate this stupid watch! It doesn't even tell the time! What kind of watch doesn't tell the time? A space-watch? This thing is useless!" Eddy shouted while pressing some of the 'watch' buttons. He then turned the hourglass to see the core pop up and a shadow resembling a humanoid figure appeared on it.

The three of them looked at it curious. "Hey what's this?" Eddy asked as he thought how to put the core down. He thought he could do it by pressing it down, and so he did. But when he did so a green flash appeared around Eddy and he felt weird as the Omnitrix altered his DNA.

When the flash was over Eddy felt different. His suspicions were confirmed when he heard Double D scream, "Oh my God, Eddy!"

"What?" Eddy asked although his voice sounded different.

"You're on fire!" Double D screamed horrified.

"What?" Eddy responded as he looked at his hands: in fact they were on fire, so were the rest of his body and his head. He was now a humanoid made of fire and burning red coal, and also he was as tall as Ed and had the same hourglass symbol that the 'watch' had, only that it was on his chest.

"Aaahhh! I'm on fire! I'm on fire! Yaaagghhhh!" Eddy screamed as he started running and then dropped to the ground and rolled, trying to put out the flames. He stopped once he realized he didn't feel any pain. "Hey, I'm on fire and I'm okay. Check it out. I'm totally hot!"

"Eddy, are you okay?" Double D asked him. 'Eddy' raised his hand and a ball of fire came out of it and shot towards a pile of junk, burning it and making it explode.

"Woah! I didn't want to do that!" 'Eddy' exclaimed in shock. He then looked at his hand and have a thought. "I wonder if…"

He put his other hand like a gun and fired it, shooting an even bigger fire ball at another pile of junk, making it explode. He then started shooting different balls of fire from his hands to different piles of junk, burning them and making them explode.

"This is really fun!" 'Eddy' exclaimed.

"Eddy! Careful! You could start a fire!" Double D adverted.

"Please Sockhead, I'm too good for that. Only an idiot would start a fire…" 'Eddy' responded.

"Double D, is Eddy going to stay as a monster forever?" Ed finally asked.

"Well Ed, I don't know but I definitely think he's not a monster, he's an alien." Double D responded. Ed and 'Eddy' stared at him in wonder.

"Well that watch that turned him into this creature came from outer space so he must be an alien." Double D simply explained.

"Why so?" Ed asked doofusly.

Double D simply stared at him before turning around and seeing that 'Eddy' had disappeared. "Hey, where did Eddy go?"

Meanwhile with 'Eddy':

'Eddy' was running through the lane, thinking what to do with his new powers. Suddenly he saw Kevin riding his bike in the distance. Eddy grinned mischievously. He put his hands together, forming a great ball of fire with them and then shot it towards Kevin's bike, making it explode in pieces and sending Kevin flying through the air.

"Woaaaah!" Kevin screamed terrified and not knowing what was happening.

"Hahaha! If you can't take the heat then get out of the fire line, Sovel-chin!" 'Eddy' exclaimed.

"There you are!" said a voice. 'Eddy' turned around to see Ed and Double D running towards him.

"Eddy... where… were… you?" said Double D between deep breaths as he was too tired from running. "We been looking for you!"

"Talk mister or else!" said Ed threateningly.

"Or else what? Did you forget that I'm hot now?" 'Eddy' said.

"You're more like heat, and since you can shoot blasts that makes you a Heatblast!" Ed responded.

"Heatblast, huh? I like that name, I think I'll use it from now on." 'Eddy', now known in this form as Heatblast, said.

"Eddy, this is serious! We have to find a way to change you back to normal before someone sees you!" Double D said.

"You're just jealous that I'm finally taller than you!" Heatblast responded. Just then the hourglass symbol he had on his chest started doing a beeping sound and flashing a red light on and off. "Hey… what's that?" asked Heatblast before a red light enveloped him and when the light died down he was back to being Eddy again, much to his disappointment.

"What?! And just when I had picked a new name!" Eddy said annoyed. Just then, Ed lifted him by his hair. "Hey!"

"Let's go to your house so that we can talk about this 'watch' of yours." Double D said with air quotes before walking alongside Ed.

They arrived at Eddy's house and entered his room directly so that they could talk privately.

"I think we should tell our parents about this." Double D said.

"What? Why?" Eddy asked.

"Eddy, that watch could be dangerous. We need to let someone know." Double D said.

"Double D, I can't get this thing off. If you let someone know, they might cut my arm off or kill me with their experiments. Is that what you want?" Eddy asked.

"We'll be three no more! Like Hop, Skip and no Jump! Like Up, Up and no Away! Like Blah, Blah without the other Blah!" cried Ed with tears.

Double D thought about it for a bit and with Ed and Eddy begging he made his decision.

"All right already! We'll keep the watch a secret! Happy?" Double D asked.

"Yay!" Ed said as he hugged Double D and Eddy tightly. "We are three once more!"

"Let go Lump!" Eddy said as he pushed out of Ed's hug. Just then the 'watch', which until that point had become red where it once had been green, did a beep sound and its green color returned. Eddy deduced that it had needed to recharge and that he could now use it again.

"I want to be Heatblast again!" Eddy said as he pressed the hourglass and the core popped up.

"Eddy, wait!" Double D tried calling him but to no avail, Eddy smacked down the core and the green light enveloped him again, however, when the light died down there was no trace of Eddy as he looked to have banished. "Eddy? Where did you go?"

"Hey! What happened?! Why is everything so big?" Double D heard a tiny voice ask. He looked under him and found what appeared to be a dark green alien with big green frog eyes that wore a yellow jump suit with a thin vertical red stripe going down it (much like Eddy's t-shirt) and also had the hourglass symbol of Eddy's 'watch' on its back. Double D assumed that it must be Eddy.

"Well, well, well. Just who are you taller than now Eddy?" Double D said with a smug smile.

"Shut up Sockhead! And help me go back to normal!" cried 'Eddy' in his new form.

"Didn't you want to stay as an alien? Why not this one?" laughed Double D.

"Awww! You look adorable! Like those aliens from Neptune Attacks!" Ed said as he grabbed 'Eddy' with his hand and lifted him up.

"Hey! Let go Lumpy!" 'Eddy' angrily cried.

"I'm going to put you in a soda can and use you to play with my other figure actions." Ed happily said as he started walking towards his house with 'Eddy' in his tiny alien form still in his hand.

"No! Ed! Let me go! Let me go!" 'Eddy' cried desperately.

Meanwhile in space:

In Vilgax's ship, his radars had finally detected the signal of the Omnitrix activating.

"I'm getting close…" Vilgax said as his radars tracked the signal of the Omnitrix and his ship took course towards Peach Creek.
