What are the Anti-Fairies doing back on Earth? Didn't Timmy already defeat them in the previous story? And why did they choose this moment to return?

Chapter 2: Meet the Anti-Fairies

"Hello, Timothy," Anti-Cosmo greeted Timmy.

"What do you want?" Timmy growled. Tootie had never heard her boyfriend so furious.

"Um, Timmy?" Tootie asked. "Do you know these, uh, creatures?"

"Oh, sorry, Tootie," Timmy apologized. "Tootie, meet Anti-Cosmo, Anti-Wanda, and Foop. They're Anti-Fairies, and the evil opposites of Cosmo, Wanda, and Poof. Anti-Cosmo is the smart one, Anti-Wanda is a complete idiot, and Foop is a real brat."

Tootie blinked. "Anti-Fairies?" she repeated, shaking her head. "I feel as though I should've known that."

Anti-Cosmo and Foop began laughing, while Anti-Wanda poofed up a sandwich and started eating it with her feet. "You don't remember?" Anti-Cosmo cried. "Hilarious! The one person in the universe who should have remembered it all has had a memory wipe!"

"Remembered what?" Timmy demanded.

"Are you saying that you don't remember either?" Anti-Cosmo laughed even harder. "You can't possibly have forgotten what had happened when you went 200 years into a future?"

Timmy was confused. "I never went time traveling into the future," he insisted. "I've only gone into the past." Timmy turned towards his Fairies. "Right guys?" Cosmo, Wanda, and Poof began whistling like they do whenever they're hiding something. "Right, guys?" Timmy repeated.

"We were under strict orders not to tell you!" Cosmo blurted.

"Cosmo!" Wanda cried.

Now Timmy was thunderstruck. "Are you saying that my memory was erased after time traveling 200 years into the future?" Timmy asked. He shook his head. "What could possibly happen in the future that I needed to forget it?"

"Not the future, Timothy," Anti-Cosmo corrected. "A future."

"Huh?" Tootie asked.

Anti-Cosmo sighed. "Thirteen years ago, Timmy Turner 'saved' a certain timeline from my people, who had taken over the universe," he explained. "This resulted in a new timeline, one that is happening right now."

"But now we've come back to Earth to create a new timeline!" Foop cried. "A timeline where the Anti-Fairies are unstoppable!"

"For real this time. Hyuck!" Anti-Wanda added, having finished her sandwich.

"You can't be serious!" Poof cried. It had been the first time Timmy had heard Poof speak since the Santa Claus incident last Christmas.

Foop blinked with astonishment. "You're finally talking, you purple pain in my pants?" Foop shouted, throwing his hand in the air. "Great! Another thing Poof has taken away from me: my advantage of vocabulary!"

"There will be plenty of time to destroy Poof, my son," Anti-Cosmo assured Foop. "But first, we need that ring." He pointed at the engagement ring.

Timmy didn't understand. "Why do you need Tootie's engagement ring?" he asked. "And when did you successfully take over?"

"If I know Jorgen, you'll find out soon enough," Anti-Cosmo announced. "Grab the ring!" he ordered Anti-Wanda and Foop. Foop sent a blast of energy from his bottle towards Timmy's hand.

It hurt. The blast of black magic stung Timmy's hand like a dozen bee stings, if the bees were really humans with stingers. He knew first-hand what that felt like.

Timmy dropped the engagement ring in pain. Anti-Wanda then turned her wand into a catcher's mitt, and dove to where the ring was falling.

"I got it! Hyuck!" Anti-Wanda cried.

"Yes!" Anti-Cosmo let loose a long, evil laugh. Wind swirled and lightning flashed behind him.

"No," Tootie whispered, as she saw Timmy in pain, Poof terrified, Wanda furious, and Cosmo playing with a piece of string, not noticing the chaos around them. "Noooooooooo!" Tootie screamed.

The world seemed to vibrate from the intensity of Tootie's cry. The vibrations pushed the Anti-Fairies back, but it didn't affect Timmy or his Fairies. The engagement ring rose from Anti-Wanda's mitt and zoomed onto Tootie's finger.

A burst of white light emitted from the ring, temporarily blinding Timmy.

Once the light vanished, Timmy saw that the Anti-Fairies had disappeared as well. He turned towards Tootie, only to see her faint, as if from exhaustion.

"We have to get Tootie back to the van," Wanda instructed. "She'll be safe there."

"Why does she need to be safe?" Timmy demanded. "What's going on?"

Poof looked at his mother. "You better tell him, Mommy," he said.

Wanda sighed. "All right," she agreed. "Timmy, help us get Tootie into the van, and I'll make sure you're told everything." Wanda turned to Cosmo, who was still playing with his string. "Cosmo, we have to go!"

"Can I take Phoebe with us?" Cosmo asked, gesturing at the string.

"Phoebe?" Timmy repeated.

"I used to have a pet nickel named Philip, so this is my pet string named Phoebe," Cosmo explained. "It's a boy string!"

It was Timmy's turn to sigh. "Fine," he said. Timmy turned back toward Wanda. "You'll tell me everything once we're safely in the van, right?"

Wanda nodded. "Promise."
