Author's note: This is the dumbest thing I have ever written

"Whew!" Wander exclaimed, wiping off sweat. "I'm finally done with this fruit stand!"

"Uh buddy, you've already built seven fruit stands." Sylvia said, gesturing to said fruit stands. "I think that's enough."

Wander shook his head. "Sylvia, a marketplace can NEVER have enough fruit stands! You know what they say! 'A torkapple a day, keeps the norploots away'!"

Sylvia smiled and rolled her eyes. It had been a few months since the whole "end of the galaxy" fiasco, and the denizens of the galaxy had begun to rebuild the planets Dominator had destroyed. And of course, Wander had insisted they help with the reconstruction.

At the moment, they were helping to construct a marketplace.

All of a sudden, the sky seemed to darken. "Weird." Sylvia said. "Hey Wander, maybe we should all head inside, it looks like it's about to rain."

"Rain?" Wander looked up and immediately froze. "Uh...Syl? That's not rain."

Realization hit Sylvia like a freight train. It wasn't rain clouds making the sky darker. The entire planet was in the shadow of something huge. Namely, a massive spaceship.

Sylvia felt a wave of fear wash over her. The last time something like this happened was with...DOMINATOR. But...she couldn't be back! Could she?

Sylvia looked up, fearing the worst, but the silhouette of the ship was distinctly different from Dominator's enormous battle cruiser. Indeed, this ship was not like any ship Sylvia had seen before. It was composed of a shiny white metal, almost crystalline in appearance, and shaped like a giant head with shoulders attached.

"Oh grop, NOW who's this?" Sylvia wondered. Just when they thought they had seen the last of Dominator, THIS GUY pops up?

"Wander, I think that's our cue to g-" she turned to find that Wander was frozen in place.

"Buddy? You OK?" Sylvia asked but Wander didn't respond. He took a step closer to the massive space ship.

Squinting at the massive dark structure, Wander whispered "It looks...familiar..."

"What? You mean...you've seen this guy before?"

Suddenly, a deafening voice rang out from the ship. "ATTENTION FILTHY ORGANICS!"

The voice was female, with a posh English accent. It was authoritative, but at the same time, it was very...theatrical. Everyone immediately stopped whatever they were doing and looked to the ship.

"I am currently searching for an intergalactic fugitive." The ship projected a massive hologram of a wanted poster into the air. Sylvia's swallowed hard. The poster featured a picture of Wander, with the caption 'Tumbleweed: WANTED DEAD OR ALIVE'.

The citizens of the planet began to murmur amongst themselves.

Sylvia grabbed Wander by the arm and pulled him along. They needed a hiding spot and fast. Suddenly, Sylvia spotted a large basket next to a fruit stand. The two jumped into the basket and closed the lid over them, making sure to stay as quiet and motionless as possible.

Outside, the voice continued to speak. "My sources have indicated that he was last seen on THIS PLANET. If anyone has any information on the whereabouts of this wanted criminal, come forward NOW!"

Sylvia felt her heart skip a beat. They've been hanging out in this planet all day. Lots of people had seen them. What if someone sold them out?

Worried, Sylvia poked out of their hiding spot for a peek. The citizens of the planet nervously shifted in their spots, murmuring under the breath. Not a single person stepped forth.

Sylvia breathed a sigh of relief. What was she thinking? Of course nobody would sell them out! Everyone knew who Wander was. No one would ever dream of selling out the galaxy's most beloved hero. They were in the clear...

"Fine! We'll do this the HARD WAY!" The voice said. "Initiate planetary DNA scan!"

The villainess faltered for a moment. "No, I don't CARE how much energy it's going to take! I KNOW he's here! I can sense it! Now do as you're told and INITIATE PLANETARY DNA SCAN!"

The ship emitted a beam of light that passed over the surface of the entire planet. After what seemed like an eternity of silence, the voice finally spoke up again.

"Gotcha."

There was a loud mechanical noise as the ship whirred to life. Its mouth slowly opened, and as it did a massive laser cannon pushed its way out and aimed itself directly at Wander and Sylvia.

"Oh grop."

The duo leapt out of the basket just as a scorching laser beam blew it to smithereens, leaving a miniature crater where it used to be.

"After so many years of searching..." The unseen woman cackled with glee. Her maniacal laugh boomed throughout the planet.

"My MORTAL ENEMY! My NEMESIS! Finally, I HAVE YOU IN MY SIGHTS!" The woman spoke each and every word with such relish that it was almost hard to take her seriously. "I've waited a lifetime to say these words..."

A giant panel on the ship's forehead opened up and a platform extended outwards. Standing on the platform was the largest villain Sylvia had ever seen.

She was absolutely enormous. So big that Wander would have fit nicely in the palm of her hand. She stood at ease, hands behind her back. Her face wore a maniacal smirk.

The villainess resembled something like a cross between a queen and a military general. She was lithe but muscular, like a jungle cat. She dressed in pale white attire, regal but modest. Well...aside from the impractically long white cape that flowed behind her. She had spiky white hair that stuck upwards and swayed ever so slightly in the wind, so that it almost resembled a flickering fire.

But what drew Sylvia's attention the most was her face. It almost seemed like it didn't fit with the rest of her body. Her eyes constantly twitched and her demented facial expression was ridiculously over-the-top. The contrast was deeply unsettling. Jutting out of her forehead was a shiny white gemstone, shaped like a diamond.

"Tumbleweed," the villainess spoke, gleefully savouring each syllable as it left her mouth. "You have been found guilty of crimes against the Diamond Authority! Return to me what is rightfully mine, and I, the resplendent White Diamond, will make your death MARGINALLY LESS AGONISING!"

Wander gasped. "White Diamond!" he exclaimed. "Where've you been? I haven't seen you in years! Did you get a new paint job on your ship? Fancy! I hardly recognised it!"

"Uh...Wander?" Sylvia whispered. "I'd hate to interrupt but-"

"Oh! How rude of me! White Diamond, I'd like you to meet my new pal Sylvia! Syl, this is my old friend Wh-"

"I'M NOT YOUR FRIEND!" White Diamond yelled. Suddenly there was a blinding white flash, and a sear of heat. The ground beneath Wander and Sylvia's feet exploded, sending them flying through the air.

White Diamond threw her head back and laughed. "That was a warning shot Tumbleweed! CONSIDER YOURSELF WARNED!"

The two of them sat up, their bodies aching from the impact. Wander dusted himself off and turned to White Diamond, mildly annoyed. "Hey! Is that how you greet an old pal?"

"OLD PAL?! WHA-I'LL SHOW YOU 'OLD PAL'!" White Diamond aimed the laser again. "Last chance Tumbleweed! HAND IT OVER!"

"Hand what over?"

White Diamond frowned. "Fine. Enjoy your last precious moments alive Tumbleweed!" she cackled. "I guess I'll just have to loot it off your IMMOLATED CORPSE!" She pointed down at the duo in an exaggerated manner. "FIRE!"

There was a long awkward silence.

"AHEM! I SAID FIRE!"

More silence.

"Uh...MOONSTONE?!" White Diamond shouted. "Why aren't my enemies suffering an agonising death right now?" A bored voice came from within the ship that was just barely audible.

"We don't have enough energy for another blast, my diamond. The energy crystals have been depleted. They need to recharge."

"WHAT?!"

"I told you the planetary scan was a bad idea."

White Diamond pinched the bridge of her nose. "Ugh, remind me to shatter you later."

"Buddy, I think it's time for us to go." Sylvia whispered.

Wander nodded in response and took the bottle of orbble juice out of his hat. He turned to the ship and, cupping his hands around his mouth, he shouted "Hey White D!"

"I TOLD YOU NEVER TO CALL ME THAT!"

"It's been great seeing you again! But you seem real busy, so I think it's best if me and Syl just skedaddle on out of here! Planets to visit, sights to see, you know how it is!"

Wander blew an orbble around the two of them. As soon as he did, Sylvia took off from the planet at breakneck speed.

"Oh, LEAVING SO SOON?!" The massive ship turned to face the duo as they fled. White Diamond shook her head in mock disappointment. "There's nowhere to run Tumbleweed! I'll tear this galaxy apart until I find you!"

"Leave him alone!" Sylvia snapped. "My pal here hasn't done anything! What do you even want from him anyway?"

White Diamond's face contorted with anger. "What do I want with him? I want him to suffer a painful demise! I want him to beg for mercy as I eradicate his physical form!"

She grinned. "But most of all...I want him to return what he STOLE from me all those years ago!"

"Stole?" Sylvia wondered aloud.

"YES!" White Diamond cried. Her voice was now fading into the distance but it was still clearly audible. "You ask me what I want, fleshy blue steed? I want VENGEANCE! I want JUSTICE!"

"I! WANT! MY! HAT!"

YAY! Crossover! This is my first ever fanfic for this show. I'm not entirely sure if I really want to continue this story but I do have a few ideas. And trust me, it only gets dumber from here on out.
