Author's Note: Yes, I have done it. I have created the ultimate crossover, with my Fairly Oddparents OC, Piper Johenson, and Purpledino25's OC, Lexi Sanders. This chapter mostly focuses on the little stuff, but we'll get into the main plot in a little while.

I'm not exactly sure who Timmy should end up with by the end of the story: Piper or Lexi. Of course, in my story, Magic Carpet Ride, Timmy and Piper will be married…but this is an alternate universe, and it's confusing as it should be. So that's where you people come in! In your reviews, just tell me who you think is better for Timmy (in this story).

Disclaimer: Butch Hartman owns FOP, and Purpledino25 owns Lexi and Diamond. I own Piper, Dezzie, and my other OCs. So don't even try to steal them from me!

Lexi Meets Piper

Chapter 1

"Hey, Timmy!" Piper Johenson waved to her best friend, none other than Timmy Turner, as she hopped off of the bus and started walking towards him.

Then she froze.

Because he wasn't alone. He was standing with a girl, his and Piper's good friend. A girl with long, blonde hair and bright blue eyes. A girl who looked girly on the outside (despite her dark clothing), but who was really a tomboy at heart. A girl who Piper told all of her secrets to, but couldn't help but feel intimidated by.

A girl by the name of Lexi Sanders.

About six months ago, when Piper had moved to Dimmsdale, Timmy and Lexi had already been best friends. They were practically inseparable, but they had made room for Piper, and soon, the three of them did everything together.

Of course, she couldn't help but feel left out during certain things – inside jokes, memories of past adventures, and pictures of the two of them (Timmy and Lexi) before she had arrived.

And Piper couldn't help but notice that, over the months, Timmy and Lexi's feelings grew for each other.

Take now, for example. As she watched the two talking, Lexi grinned and said something that Piper was too far away to hear. What she did hear, however, was Timmy bursting into laughter at whatever was ever-so-funny, and clapped a hand on her back the way one football player might do to another after a winning game.

It wasn't just a friendly gesture, though. Piper knew a crush when she saw one, and the way that Timmy gazed at Lexi in that moment was definitely factoring in as a major one.

A burning jealousy erupted into Piper's chest, making her heart flutter, and her eyes widened as the realization hit her. No. It wasn't possible. She did not like Timmy Turner in that way. That was ridiculous.

Or was it?

There was only one way to find out. Crossing the street, Piper plastered a large smile on her face and smiled at her two friends, who were still laughing. "Hey, guys."

"Hi, Piper," Timmy and Lexi said in unison, laughter still clinging onto the edges of their voices.

An awkwardness unlike anything that the three had experienced around each other hung in the air. It was so thick one could reach out and almost feel it. Finally, Piper broke the silence with a simple, "So…excited for the weekend?"

"Sure am," Timmy said with a smile, at the same time that Lexi replied, "Yeah, and I have no homework as a bonus."

More awkward silence.

This time it was Timmy who spoke. "Lex and I have a baseball game tomorrow against the Eagles."

"Cool," answered Piper with a faraway smile. Why are things suddenly so weird? Piper thought anxiously. This has never happened before. Why now?

The silence returned. After a few moments of fiddling anxiously, Lexi glanced up and cracked a grin. "If anyone starts talking about the weather, I'm leaving."

Timmy cracked up laughing, and Piper couldn't help but join in. Lexi always knew just what to say in any kind of situation, good or bad. It was a skill that Piper hadn't been born with, although she wished that she had.

Both of Piper's friends turned their gazes towards her, as if it was her turn to talk. "Okay…so, either of you wanna come over to my house? There are some brownies in the fridge left over from Miranda's birthday party a few days ago, and we can watch the new Crash Nebula episode." She smiled; there, maybe it was that easy.

Or maybe not. Timmy and Lexi exchanged a guilty look. "Actually, Piper…Lexi and I were gonna go practice for the game tomorrow," Timmy explained, clasping his hands behind his back and staring at the sidewalk. "Sorry…we should've told you."

Lexi nodded energetically. "Yeah, it totally slipped my mind. But we should hang out on Sunday or something. All three of us, you know?" Her words were nice enough, and her smile was genuine, but something about the way she said it made Piper uncomfortable…like she was some sort of third wheel.

And she didn't like it one bit.

oOo

It wasn't like Piper had any other plans that Saturday morning, so instead of hanging around her house with her mom and obnoxious little sister, she walked the short few blocks to the baseball park.

The game was just starting as she arrived, and immediately Piper caught Lexi's eye. The blonde haired girl waved happily, and, after checking the batting order (she was fourth), trotted over, Timmy following close behind, a smile on his face.

"Hey!" Lexi cried, her face breaking out into a smile so large that her blue eyes sparkled. Piper found it very hard to be mad at someone who seemed so happy to see her.

"Hi, you guys," Piper greeted them. "How's the game?"

"It's great," Timmy told her, taking a seat on the bleachers, right beside her. For reasons unknown, Piper's heart fluttered. "It's only the second inning and we're already winning."

"That's awesome T – you guys," Piper corrected herself quickly, glancing over at Lexi. She had almost forgotten that the other girl was there.

That is, until Timmy ruined it. "Yeah, all thanks to our MVP!" He leaned over and clapped Lexi on the back for the second time in two days. "At her first time batting in the game, she hit a homerun and brought in three runs!"

Lexi grinned, her cheeks turning light pink with pride. "Aw, don't make it sound better than it is." Then she leaned in and added in an undertone to Piper, "Although it was pretty awesome, if I do say so myself."

"Nice," Piper congratulated, but her words were empty. Why did she feel so cold to the girl who had always been her good friend? She'd worry about it later, she decided, for the coach was calling out, "Sanders! Hurry up, you're in the box!"

"Gotta go," Lexi said and raced off, throwing off her baseball cap, pulling on her helmet, grabbing a bat and moving to the side to take a few practice swings. Piper watched her for a few seconds before Timmy's voice pulled her from her thoughts.

"You think you can stay for the whole game?"

"Huh?" Shaking her curly brown bangs out of her eyes, Piper squinted into the sunlight to look him in the eyes. "Oh, yeah. Definitely." As long as I can see you play.

Timmy grinned, looking honestly pleased. "Good. Maybe you'll be my good luck charm and I'll actually bring in a run this game."

Piper laughed, her spirits lifting. Timmy's good luck charm. That had a nice ring to it. "Yeah, maybe I will."

There they sat, smiling at each other. That moment could have lasted forever, and Piper was half expecting Timmy to lean over and kiss her on the spot (yes, unrealistic, she knew that), when a loud cheer rose up from the small crowd.

Lexi had just scored another homerun.

As soon as her feet hit home plate, her teammates surrounded her. "This game is in the bag!" one boy cried. "Lexi can hit anything!"

The girl herself laughed, high fiving her teammates as she moved towards the bench to grab her water bottle. "Thanks, guys. It's nothing, really. Don't make a big deal about it."

It was then that Piper noticed that the seat next to her was empty. Timmy had left, and by the time she looked up again, he was already right next to Lexi. Before Piper's very eyes, he reached out and hugged her tightly, practically lifting her feet off of the ground. "Way to go, Lex!"

Lex. He didn't have a nickname for Piper. Why not? Why doesn't he? she thought somewhat miserably as Timmy released Lexi and high fived her in their special handshake. He didn't have a secret handshake with Piper. Hm.

Then he did something that made her forget all about that. As Piper watched, Timmy leaned over and kissed Lexi – right on the cheek. Lexi's blue eyes widened for a second, then she grinned and hugged him again.

Piper couldn't take it anymore. She bolted.
