Hello, beautiful people. For all those out there who love Pokémon, the original Ben 10, both, or were just bored enough to take a look at this, here's a crossover between two worlds that aren't terribly different if you think about it. Enjoy, and review! Constructive criticism is welcome, I always want to make my stories better :). Takes place in the Original Ben 10 universe and Pokemon XY. Cover image is courtesy of DragonCraZ.

Ash and co.

"Lumiose City is sooooo cool!" Bonnie exclaimed.

"I agree. It's got some awesome sense of fashion!" Serena added. Ash, Serena, Clemont, and Bonnie were on their way out of Lumiose City and on their way to Cyllage City so Ash could get his second gym badge at the Cyllage gym. They were still in Lumiose City, but they were approaching the edge of it.

"It is a nice place," Ash agreed. "But I still can't stop thinking about the upcoming battle at the Cyllage City gym."

"Pika-Pikachu!" Ash's partner Pikachu chirped.

"You excited too, buddy?"

"Pika!"

"I'm interested to see how your battle goes. It's fun to watch you fight, Ash," Clemont said as the group continued to walk.

"Thanks," Ash replied. "Hey, race you to the edge of the city!" Ash quickened his pace to a run.

"You're on!" Serena accepted the challenge and began to run to catch up.

"Come on, Clemont!" Bonnie chirped to her older brother and ran off to catch up with Ash and Serena. Clemont sighed.

"Wait for me!" he shouted, running as fast as he could to catch up with his friends. Soon, Ash, Serena, and Bonnie were at the edge of the city, Clemont not far behind. Well, not too far behind.

"Hold… gasp… on…" he panted, finally reaching his friends. He put his hands on his knees to rest a bit.

"Clemont, you slowpoke," Bonnie said, raising her eyebrows.

"I'd like to see you try to run with a big metal backpack full of machines!" Clemont countered his little sister. Bonnie just giggled.

"Let's keep going," Ash suggested. Everyone nodded, and once Clemont caught his breath, the foursome continued on towards the forest that lay just ahead. But little did they know that they would have an encounter with something, or someone, that would completely change their adventure.

The Tennysons

"Aaaah," Grandpa Max sighed, leaning back on a picnic table. "Finally some peace and quiet." The Tennysons were at a playground, with a play structure, a swing set, and a grassy field beside them. A few public picnic tables were set up on the grassy field by the structures. Ben and Gwen were fooling around on the play structure. The cousins had the whole playground to themselves, as no one else was at the park.

"It's nice to be doing what normal kids should be doing on their summer vacation for once," Gwen agreed with her grandfather. She was on a side of a set of monkey bars, preparing to swing herself across them. Ben was on top of one of the tube slides that led down to the structure's base.

"For once, I agree with you," he said.

"That's a first," Max mumbled to himself, smiling. The trio continued to have a good time being normal people for once. But little did they know they were being watched.

-10-

"Ah, finally," Dr. Aloysius Animo said to himself as he sat upon his favorite mutated animal, his humongous frog. "I found that snot-nosed kid Ben Tennyson and his little gang." He patted his giant frog creature on the head.

Animo had been snooping around Iowa as soon as he heard the headlines in the Iowa news: "Fire-like humanoid alien saves burning apartment building". "Big bug-like alien stops bank robbery". Pretty good cues that Ben was around.

"Now that darn little brat will get a lesson he'll never forget!" Animo cheered, kicking his frog lightly in the sides to signal it to spring into the air. Right in front of Ben.

-10-

Ben jumped off the slide he was sitting on and decided to go over to the swing set.

"I bet I can get higher than you on the swings, Gwen!" he called to his cousin.

"You're on, dweeb!" she shouted back, dropping from the monkey bars she was hanging on. She began to run towards Ben, who was making his way towards the swing set. Suddenly a shadow was cast upon the cousins. Ben and Gwen stopped and looked up to see what had blotted out the sun. The answer landed with a loud thud in front of Ben.

Animo's giant frog, along with the twisted Doctor himself, landed just in front of where the 10-year-old boy now stood. The ground lurched as the massive frog landed, causing Ben and Gwen to jump. Max saw what was happening and ran over to his grandkids. He sighed as he did so. And to think we were having a normal day for a change, he thought to himself, a little disappointed.

"Animo!" Ben and Gwen chorused.

"What's this all about?!" Max demanded as soon as he reached the two kids.

"This is about revenge, Mr. Tennyson. Revenge for you," he pointed to Ben, "always ruining my plans!"

"Sounds about right," Gwen acknowledged. Ben folded his arms.

"Dude, you've already had a chance to rule the world, and you blew it. You've had tons of tries for revenge and none of them have worked. What makes you think you can win now?" he asked, eyebrows raised.

"And, speaking of the whole take over the world episode, how'd you guys get out of that for force field?" Gwen put in.

"Okay, first, we got out of the Plumber base with Rojo's alien tech. We dug into the floor, but realized there was a force field there too. But Rojo had some alien tech that found a weak point in the force field, and we managed to break through," Animo explained. "And second, your smart remark question," he narrowed his eyes at Ben, who still had his arms crossed, "I've taught my pet here some new tricks!" Animo flashed a crooked-toothed grin and kicked the mutated frog once more. The mutant croaked and sprung towards Gwen. She dove out of the way, and Max, who was right behind her, dove as well.

"Time to give this doctor a lesson!" Ben shouted, setting the Omnitrix to Wildvine. He slammed it down, but when the bright green flash was over, Wildmutt stood in Ben's place instead of his chosen Flourana form. He growled, annoyed at the Omnitrix's malfunction, and leapt towards Animo's frog, teeth bared. The frog leaped over the Vulpimancer quite easily and shot out it's sticky tongue. Wildmutt rolled out of the way as not to be reeled in by the mutant frog.

"Alright, my pet, do your stuff!" Animo shouted. The frog took in a big gulp of air, making its vocal sac grow to look like a huge bubble. Then the creature opened its mouth and out came a croak so loud it violently launched everyone that stood in its path backward. Wildmutt clutched his ears (wherever they were) at the sound, his hearing much more sensitive than Gwen's or Grandpa Max's. Everyone got to their feet after hitting the ground hard.

"Now that I have your attention," Animo said, "this is also something that will make this fight different from the rest." He pulled out a device that looked similar to the Null-Void Projector, but instead if the light on the end glowing yellow, it glowed fiery red. Gwen's eyes widened when she saw the device.

"The Null-Void Projector?" she gasped.

"No, but similar to it, I believe," Animo replied. "You see, it runs on a power source that is extremely rare called Genosite. It can only be found in a few extremely old fossils. I only have enough of it to send one of you through to this other unknown world."

"So you have no idea what's on the other side?" Max asked. He had never heard of a device such as this before.

"Not in the slightest. But once I get rid of you three, it'll make taking over the world a whole lot easier!" Animo replied, grinning evilly. Wildmutt growled. "Let's try this think out now, shall we?" Animo pointed the device at Max, who took a step back. Wildmutt sensed that his grandfather was in trouble and ran towards him. Animo pulled the trigger, sending a beam of red light towards Max. Wildmutt dove in front of his grandpa and took the hit from the light beam.

"Ben!" Max shouted. Gwen gasped.

"Yes! Revenge is mine!" Animo cheered as Wildmutt disappeared from view. Max took out a small cube from his pocket, hiding it from Animo, and clicked a button on it. He flung it at Animo and it changed into a net. When Animo realized what was coming for him, it was too late. He fell off of his huge "pet", tangled in the net.

"Gwen, go to the Rust bucket and get the Null-Void Projector," Max said to his granddaughter. She nodded and ran to the old school RV, which wasn't far away. She went in, grabbed the projector, headed out, and gave it to Max. Max pointed the projector at the humongous frog, pulled the trigger, and away it vanished just as Wildmutt had.

"I'll call the police so they can pick up Animo," Max said.

"Okay. I'll be on the swings," Gwen replied and ran over to the swing set. As she sat on a swing, she thought about Ben and wondered how he was handling the strange new world. I hope he's okay, she thought to herself. He could be a major doofus sometimes, but he was family. Be strong, Ben.
