My very first crossover! My inspiration for this is because I always thought there should be a crossover between these two shows and I was surprise no one has ever done it. So it looks like I'm the first. So please enjoy and give feedback.

Pokémon and Rugrats belong to their respective creators and I own nothing.

Quick note: Some words will be deliberately misspelled and misused as a way to mimic the way the babies talk. I also plan on having characters from Pokémon make appearances as well. Enjoy and please review.

Update: I fixed my spelling/ grammar errors, excluding deliberate ones for when the babies talk. Story is now written in present tense instead of past tense. I apologize if any unintended spelling/ grammar errors remain.

The lights switch on, throwing the arena from out of the darkness. On one end of the battlefield, a girl with blond hair and close to the age of three stands with her arms folded, and smirks an intimidating smile. The girl is confident, wearing a purple dress, and her hair arranged into two spoinktails.

"So, you challenge me to a pokymon battle, baldy?" the girl asks her challenger.

"I sure have Angelica, for my name is Tommy Awfully Bald Pickles," the eight month old baby, in the blue t-shirt and regular diaper responds. "Do you accept my challenge?"

"I never turn down a challenge, even if he's a stinky baby," Angelica replies.

A spot light shines above a redheaded toddler wearing a referee's outfit, as he approaches the middle section of the battlefield. Tommy recognizes him as Chuckie. He speaks into the microphone, "This will be a one-on-one battle. No substitutions." Taking a deep breath he blows in to a whistle. "Begin!"

"All right, Fluffy, I choose you!" Angelica says.

The poké ball opens up to release a purple cat-like pokémon known as purrloin, wearing a bow on each ear.

"Purrloin," she says.

Tommy smiles, staring at his opponent. He reaches into his diaper and pulls out a regular poké ball and throws it. "Spike, I choose you!" he hollers as a houndour exits the poké ball.

"Fluffy, use night slash!" Angelica orders. Fluffy's claws turn in to a whitish purple color, and she charges for Spike, ready to swipe him.

"Spike, dodge and use fire fang!" Spike successfully dodges Fluffy's shadow claw and, with his mouth forming fire, lunges at the dark cat pokémon.

"Fluffy, get out of there! Hurry!" Too late. It's a direct hit and Fluffy goes flying.

"Yay!" two identical siblings cheer from the stadium, wearing matching outfits that are teal green with a yellow ducklett print.

"I'm your biggest fan!" the male sibling cheers.

"No Phillip, I am," says the girl sibling, retorting her brother.

Phillip, or Phil, leers at his sister. "No Lillian, I am!"

"No, I am!"

"No, me!"

"Me!" Lillian, or Lil, retorts.

"Can you continue?" Angelica asks Fluffy. She nods to her trainer, ready to continue the battle. "Great. Now, use furry swipes!" Long claws emerge from Fluffy's paws and she charges towards Spike, who is readying for Tommy's command.

"Okay Spike, let's finish it off with flamefrower!" Spike releases a stream of fire.

"Fluffy, dodge and use another night slash!" Fluffy successfully dodges and swipes at Spike, causing pain. The cat pokémon snickers.

"Spike, you okay!" Spike barks, showing no weakness.

"Wait ago Spike, you can beat that nasty Angelica!" Chuckie roots.

"What was that Finster?!" Angelica growls.

He defends himself by replying with, "Nothing."

"Spike use flame charge!" On Tommy's command, Spike engulfs his body with flames as he charges towards Fluffy. For some odd reason, Fluffy and Angelica remain perfectly calm.

"Tommy's gonna win!" the twins cheerfully exclaim.

Just inches from impact, Angelica orders, "Fluffy, use hydro pump!" A powerful blast of water shoots out of Fluffy's mouth, sending Spike flying.

"What!?" Phil, and the others, shout in udder shock. Phil adds, "Purrloin's can't learn hydro pump! Can they?" Lil just shrugs her shoulders.

"Spike, can you still battle?" Tommy asks. Spike tries to get up but faints. He looks back at Angelica. "But how did Fluffy do that?" he stutters.

"It's a nightmare doofus; what I say goes," Angelica explains mockingly. Fluffy mocks as well.

"Not so fast Angelica, I'm still referee, and you are –" Chuckie vanishes into thin air and an adult known as Angelica's dad, Drew Pickles, replaces him. "The winner, for the most brilliant display ever – my precious little angel," Drew remarks. "And as winner, Angelica may now claim your pokymon!"

"Ah!" Tommy screams. He looks around to see that he is still in his crib and his trusty friend Spike, the houndour, is peacefully sleeping by his side.

"That mean old Angelica. Why must she always cheat, even within my own dreams?" Tommy looks back at Spike and smiles that it was just a nightmare, and that Spike is all right. He pets his companion's head and goes back to sleep.

"I can't wait till I go on my pokymon journey and become the very best."

So, what did you think? Other chapters will be longer. Hopefully I can figure out how to upload chapters. Hope the improvements made it more enjoyable to read.
