I don't own anything except for my OCs.

In the Griffins' house; Meg and Eddie were getting on bed. Meg (wearing a pink negligee and matching panties) was brushing her hair.

(A/E Fan: Hey wait a minute, I thought this was…

Me: Shut up!)

"Aw, isn't it relaxing to have a night for ourselves after thousands of missions?" Meg asked.

"Yes, it is" Eddie answered, coming out of the bathroom and dressed up as Emma. He was wearing a frilly blue bra and matching panties.

"Oh, really?" Meg asked, annoyed.

"Come on, I found it harder the chance to crossdress" Eddie/Emma said "Besides, I'm sure most of our friends want to wear clothes of their opposite sex"

"I highly doubt that" Meg commented.

"How 'bout you?" Eddie/Emma asked "You never was interested on wearing my clothes?"

"Oh, please, like if I'd like to wear smelly and sweaty male underpants" Meg said "Except yours are soft, delicate and...worn by you"

"I bet a lot of couples do that, maybe our friends in Langley Falls" Eddie/Emma said "Isn't Halloween, like, next week?"

"What do you have in mind?" Meg asked "A costume party?

"Even better: a Costume Party Contest!" Eddie/Emma answered "We'll challenge them to all the couples to crossdress and see who's the most convincing crossdresser! Aside of me, of course"

"Sounds super sexy" Meg said.

"But tonight..." Eddie/Emma said as they both started making out before their passion night.

Meanwhile, Hayley was finishing giving Mary a bath. Jeff puts on her diaper and outfit.

"Isn't she so cute?" Jeff smiled.

"She sure is" Hayley agreed.

Steve walks into the bathroom.

"Hey guys, guess what? Eddie Walker and Meg Griffin are inviting us to their Halloween party and they're coming here to Langley Falls!" Steve cheered.

"Really?" Jeff asked.

"You bet! They sent us an invitation and we can invite our friends as well" Steve added as he shows them an invitation card that reads "Costume Party Contest": The Best Crossdresser Costume Wins!" Hey wait a minute, crossdressing?"

"What?!" both Hayley and Jeff asked in unison.

"I don't know. I do want to go but I don't know about how Zoey feels" Steve wonders.

"We're going!" Hayley said.

"Hell yeah babe! Eat some candy and reunite with our friends. I can't wait to travel to Quahog" Jeff said.

"Actually, they're visiting us here in Langley Falls, as I recall" Steve corrected. "That means we don't have to travel!"

"What's crossdressing?" Mary asked.

"Uh...we'll tell you when you're a little older" Jeff said as he pats his daughter's head.

"Halloween party! Yes! I'm down!" Zoey cheered and hopped like Pinkie Pie as the scene shifts to her house. "I have no plans so hell yeah I'm down!"

"Not just a Halloween party, but a costume contest as well" Steve added.

"That is freakin' sweet!" Zoey added as well. "Oh crap, did I steal that quote from somebody?"

"You sure did!" Peter Griffin's voice was heard miles away.

"Sorry nice man!" Zoey apologized.

"So anyways, what will you dressed up as?" Steve asked.

"Like this" Zoey goes into her closet and dons a Korra costume from Legend of Korra.

"I'm the Avatar! You gotta deal with it!" Zoey shouted as she tries to airbend, but fails miserably.

"That's great, but Zoey there's a catch" Steve added.

"What is it?" Zoey asked.

"It's a...(gulps) crossdressing costume contest" Steve answered.

From hearing that, Zoey instantly has deja vu moments of Steve stuck as Stacy. She sees moments where Steve was transformed into Stacy and was stuck with her after Lucy was "defeated".

"Oh no" Zoey whimpered.

"Are you okay?" Steve asked.

"When is this party?" she asked.

"Next week" he answered.

"Oh I don't think I can make it" Zoey said.

"But I thought you said you were free" Steve reassured.

"Actually, I totally forgot. I have a history test to study for" Zoey said.

"Zoey, are you hiding something from me?" Steve asked.

"No why?" Zoey wondered.

"You look scared and I want to know why" Steve said.

"I told you I'm fine. Look, if I have time, I'll go to the party. I'll meet you there, I swear" Zoey said.

"Well, okay. I have to go. Think about it" Steve said as he kisses her lips and left her house.

"Not again!" she whimpers as bad memories of Steve being Stacy were reappearing again.

"So I heard" a mysterious voice said.

Meanwhile, Mark was helping Adaline...model her new dress.

"Adaline, what's all this?" he asked.

"It's for my BFF's quinceanera" Adaline answered.

"I'm glad I'm wearing regular clothes and not having to wear it actually" Mark commented.

Suddenly, an envelope shows up in front of Mark's face.

"What's this?" Adaline opens it.

"Hello? What about me?" Mark asked.

"Hmm, it's from someone named Meg Griffin and another person named Eddie Walker. They said that they're coming to Langley Falls for a Halloween costume contest. We should go" Adaline said.

"I've never heard of those two but I love to go, but I'm scared about how they look or if it some form of scam" Mark commented.

"Relax, take a look" Adaline said as she showed Mark her iPhone with Hayley's Facebook page and there was a photo of her, Jeff, Meg, and Eddie smiling together.

"I guess we can trust them" Mark smiled.

"Perfect! We're going to need some costumes" Adaline said.

"I know what I'm wearing" Mark said as he left and donned a Zorro costume.

"I am Zorro, the Mexican warrior" Mark said with a Spanish accent as he slashes an M on Adaline's dress.

"Mark, first of all, Zorro isn't Mexican. Second of all, you ruined my dress" Adaline grumbled as it falls down, revealing her pink bra and matching bikini panties, but she quickly dons another dress. "Third of all, it's not just any costume contest. It's a crossdressing costume contest."

"Huh?' Mark asked.

"In fact, I get to dress up like a boy and you get to dress up like a girl" Adaline said.

"Oh my God, am I going to be like Steve? It's going to feel weird" Mark said.

"Come on, I'll help you out" Adaline said as she dragged him to her room.

"Here, try this one!" Adaline gave him a pretty princess pink dress.

"Adaline, I'm not sure" Mark said.

"Hey, if we're going to win, you gotta be the girliest guy of the party!" Adaline explained.

"Okay, as long I don't have to wear..." Mark was interrupted.

"BRA AND PANTIES!" Adaline exclaimed as she also took out a pink bra and white panties with pink laces.

"NOOOOOOOO!" Mark shouted as the camera zooms out of the building.

Meanwhile, Zoey walks around in her room, thinking nonstop about Stacy.

"I don't think I want to go. I just can't go" she told herself. Her cellphone vibrates.

"Zoey, it's okay if you don't want to go. I understand. I won't get mad" she reads a text message from Steve.

"Hang on" Zoey takes a nap.

(Dream Sequence 1)

Lucy Sheridan from Wrath of Lucy transforms Steve into Stacy and destroys her spell, preventing Steve from becoming male again.

(Dream Sequence 1 Ends)

Zoey twists around in her nap in fear.

(Dream Sequence 2)

Stacy undresses Zoey, revealing her black bra and panties and they make out on the floor. Zoey's parents arrive as Michael's eyes were covered by the hands of Kat.

"How could you?!" Kat shouted.

"Sorry girl, I'm still Stacy" Steve/Stacy taunted.

(Dream Sequence 2 Ends)

"No!" Zoey's scream was heard from the outside of her house.

"I think that's Zoey" Steve said as he was giving invitations to Barry, Toshi, and Snot for the Halloween party.

"I think she's having explosive diarrhea. I would scream that loud whenever I eat KFC" Barry commented as Steve smacks himself in the face.

"Steve, maybe she's scared that she will be the least prettiest from the girls" Snot said.

"Well, it has to be something. I'm going for it" Steve leaves.

"Anata wa mijukudesu (You guys are immature)" Toshi commented.

A week later, it was the Halloween party. Meg and Eddie are arriving to Langley Falls, with the Halloween party materials.

"This is going to be so much fun" Meg said.

"You bet. Meg, do you think it's a good idea to leave our baby girl with your dad?" Eddie asked.

We see Peter and Gwen...watching My Little Pony: Friendship is Magic together.

"This is beautiful! They look so pretty!" Peter cheered as he was crying while watching with his granddaughter.

"It's fun" Gwen said.

"I don't know. Mom has to do grocery shopping and Chris is busy with Amy, so we don't have a choice. I promise this will be a fun costume contest" Meg commented.

"I think it's time for a commercial break" Eddie said as someone hands him a piece of paper.

"Oh crap, it reads here that because pen123 hasn't uploaded a chapter in more than two weeks, he has to air an episode commercial free for the satisfaction of the fans. Sweet!" Eddie smiled.

"Who?" Meg asked.

"Never mind. We're here" Eddie said.

"Soon, my friends" the same mysterious voice said.

Meanwhile, Adaline finished dressing up a girl with blonde hair and a princess costume.

"You look wonderful darling" Adaline smiles.

"I don't know" the girl had a masculine voice.

"You have to sound girly, Mark" Adaline ordered.

Later, the community building was filled with Halloween decorations.

"I think we did a great job! I'm so glad the owner was generous of letting us borrow this place" Meg said.

We see the owner playing with Flaming Knight and Pink Arrow action figures.

"I think I'm in Heaven" he laughs.

Now in the party in the community building, Meg (dressed up as Anakin Skywalker) and Eddie (dressed up as Rey from The Force Awakens) were in the podium to give a welcome to the contestants as they enter.

"Welcome, lovely couples of Langley Falls!" Eddie greeted.

"I hope you're all excited for the contest" Meg said.

Everyone at the party cheered.

"We'll all come to judge your costumes by how convincing you look as your opposite sex" Eddie said "In order words, how feminine the gentlemen look."

"Or how masculine the ladies look" Meg added.

"GOOD LUCK!" Meg and Eddie said.

We see Hayley and Jeff dressed as John F. Kennedy and Marilyn Monroe, respectively.

"Hey babe, look how hot I look" Jeff does the famous Monroe dress blowing pose, but he's wearing his whitey tights underneath.

"Jeff, you're still wearing underpants" Hayley said as she dragged Jeff out of the wind.

"Babe, I'm not comfortable wearing panties" Jeff explained.

"Then just don't wear any underwear then" Hayley suggested as she removed his whitey tights.

"But what about my…" Jeff was stopped as Hayley does something in ultra speed motion. "Much better."

Snot and Lana arrived, dressed as Wendy and Dipper from Gravity Falls, respectively.

Barry and Bethany are dressed up like Mrs. Pacman and Pacman.

Toshi is dressed like Sailor Moon while his girlfriend Lindsay is dressed like Ash Ketchum.

Mark is dressed as a princess while Adaline is dressed as Flaming Knight.

Then Meg and Eddie approached Mark, Adaline, Steve's friends and their girlfriends.

"So, Steve and Zoey told us about you guys" Meg said. "I'm Meg. Nice to meet you guys."

"Nice to meet you too" Adaline smiled.

"Haha, you look so pretty" Eddie commented.

"I'd wish this dress was a little longer" Mark said, pulling down his fairy dress "My panties are showing, but thank God I've shaved my legs before arriving here."

"Also, whoa, I'm impressed you're dressed as Flaming Knight" Eddie said to Adaline

"He's my favorite Ultimate Hero since he uses powers from my homeland Innerland" Adaline said "I'd wish I could meet him."

"Well, you have him in front of you" Eddie said.

All the friends were astonished to know about Eddie's secret identity.

"Oh my God! Oh my God! Oh my God! Oh my God! Oh my God!" Steve's friends and Mark and Adaline went crazy as they met Eddie aka Flaming Knight in front of them and Snot began touching Eddie's hair.

"Oh my God, it is you! Can I have your autograph?" Snot begged as Eddie sighed and signed Snot's napkin.

"Anyone else?" Eddie asked.

"Can we take a selfie?" Adaline begged as she, Mark, and Eddie took a photo together.

Meanwhile, Steve and Zoey are eating at Pizza Overlord, but they look very bored and quiet.

"Steve, are you mad we're not at the party with everybody else?" Zoey asked.

"No, I'm not mad" Steve said.

"Look, I'm scared" Zoey said.

"What are you scared of?" Steve demanded.

"I can't tell you. You wouldn't understand" Zoey confessed.

"Zoey…" Steve snapped.

"(Sigh) I...I...I don't want to see Stacy again! There, I said it! It took decades for you to return as Steve and I'm worried that Stacy will return! There, I said it!" Zoey confessed.

"Is that why?" Steve asked.

"Yes, I know I sound like a scaredy cat. Please don't get angry. I do want to go but I don't want Stacy back again" Zoey began to shake.

"Zoey, it's okay. Stacy is gone. You will never see her again. Here" Steve takes out his boy-to-girl pills and smashes them and throws the powder into the garbage.

"Zoey, we don't have to dress up. Let's just go there and have some fun. We'll dance to some music and hang out with Meg and Eddie. Besides, they want to see us again" Steve suggested.

"You know what? You're right. We just won't enter the contest. We can just go and have some fun. I'm sure they'll understand. Come on. Here, to show you I'm sorry for my stubbornness, I got this" Zoey pays for the pizza with her cash money and they leave.

Later, we see Eddie looking at the guys as girls while Meg look at the girls as guys.

"They look very good. It's hard to tell" Meg said as she writes down scores on a notepad. Eddie does the same.

"Adaline, how long will I have to wear this?" Mark asked.

"Mark, you need to ask me in a girly tone" Adaline snapped.

"Fine! (Squeaky voice) how long will I have to wear this?" Mark asked again.

"Much...better?" Adaline questions.

Meanwhile, Meg and Eddie arrived at the podium.

"Alright, guys, it was a tough decision, but we decided who's the winner" Meg said. "For us, you guys are all winners in our book, but there can only be one winner."

"And the winner is..." Eddie said.

Then the lights out.

(Screaming)

We see the friends all completely...dead!

"(Laughs) I, the Phantom of the Costume Contest, strikes!" it was...Roger disguised as the Phantom from Phantom of the Telethon who arrived.

"Well, we're almost here" Steve said as he and Zoey arrived.

"Oh my God!" Zoey screamed at the sight of their friends covered with blood and look dead.

"Who did this?!" she demanded.

"(Laughs evilly) I the evil Phantom has killed your innocent friends!" Roger shouted.

"What have you done to our friends?" Zoey demanded.

"(Laughs) your stupid friends stole my idea! I wanted people to support my idea but nobody listened to me" Roger said.

"What are you talking about?" Steve asked.

"The costume contest was my idea!" Roger shouted.

"You never said anything about it" Steve snapped.

"Yes I have!" Roger said.

(Flashback)

"Want to come to my costume party?" Roger said as he asked Steve and Zoey, who were playing video games in the Smith living room.

"Ask me later" Steve said as Roger leaves.

"Want to come to my costume party?" Roger asked Hayley and Jeff, who were playing fort with Mary.

"Not now dude" Jeff answered.

(Flashback Ends)

"Wow, now I feel like crap" Zoey said.

"You bet your ass you should! Now, if you want your friends back, you will tell them that this was my idea!" Roger demanded.

"But Eddie turned it into a crossdressing costume contest" Zoey said.

"Oh, smart girl, eh? Well guess what? I'm going to kill you...with my keyboard!" Roger takes out the same keyboard from The Phantom of the Telethon and plays some notes.

"I don't get it" Zoey said.

"Hang on, hang on" Roger presses a key and it plays "Rockit" by Herbie Hancock.

"Okay, that's not it" Roger said as he presses another key and this time, it plays the right notes from the episode.

"There we go" the alien laughed.

"Okay, are you going to attack us or not?" Steve asked.

"All right I'm going to attack you now!" Roger plays the keyboard but stops for a moment.

"Hang on, let me try this on the fart setting" Roger said as the keyboard makes fart sounds with the same tune. Steve and Zoey made grossed out looks.

"I don't know. It's funnier, but I think it takes out some of the tension" Roger explained.

"Run!" Zoey shouted as Roger takes out a bloody knife and chases them.

"Zoey, why are we running? Remember, we're the Ultimate Heroes and not Roger!" Steve suggested as he took off his clothes, revealing his Super Karate Kid costume.

"Steve, I don't have my costume on. It's laundry day" Zoey said.

"Here" Steve hands his girlfriend some toothpicks. "Throw them at Roger."

Zoey does, but the alien slashes them off.

"It's no use. I don't have my pistol sword" Zoey said as she and Steve tripped, as Roger was about to stab them, only to see...the bloody knife was actually plastic.

"What?! It was only a toy!" Zoey shouted.

"(Laughs) the looks on your faces are priceless! That was genius!" Roger laughs.

"Roger, you stop right this instant!" Steve demanded.

"All right, I "killed" your friends but you can have them ressurrected again" Roger insisted.

"What do you want from us?" Zoey asked.

"All you have to do is beat me in a…Force Crossdress showdown!" Roger demanded.

"Huh? I don't get it" Zoey said.

"All you have to do is crossdress...him" Roger points at Steve.

"No I can't!" Zoey shouted as scenes of Stacy reappear in her mind again. "I can't do it!"

"Oh, I guess you don't care for your friends. Fine then. They're dead for good!" Roger laughs evilly.

"No, how about I crossdress my girlfriend again? I can have her disguise as Ash from the Kalos League just like how Serena did it" Steve suggested.

(Cutaway)

We see Serena reading this special.

"It was supposed to be private!" she runs away as she shuts off her computer and leaves while crying.

(Cutaway Ends)

(A/E So sorry Serena fans. I'll make it up. I swear. Thank you Haven Paschall for guest starring for this tiny segment.)

"No, it's either Steve disguise as a girl or no deal" Roger refused.

"I can't!" Zoey panicked as she started to tear up.

"Zoey, it's simple: just dress Steve as a sexy blonde bimbo with large boobs and a sexy dress and I'll have your friends be back alive again" Roger demanded.

"What if she comes back?" Zoey trembled.

"Who?" both Steve and Roger asked.

"Stacy" Zoey whispered.

"Well, it looks like I win" Roger said as he quickly dresses up Steve as a sexy blonde girl. "Ladies and gentlemen, you're looking at the sexiest guy-girl in the whole wide world!" the audience cheered. "Zoey, you have 5 minutes to defeat me! Beat me or your friends are gone!" Roger laughs evilly as he vanishes with his cape.

"I can't" Zoey whispers.

"Zoey, just do it! Stacy does not exist. The pills are gone! It's okay. I promise that Stacy will not show up. Don't think about it and dress me up as a girl! Just do it!" Steve demanded.

"Okay" Zoey said in a soft voice as she undresses Steve, revealing his whitey tights.

"Okay, it's just Steve. He's in his boy underpants. It's okay" Zoey told herself as she puts on a dress on Steve. However, she falls back as a huge glowing light appears.

"I will never go away! (Laughs evilly)" an imaginary Stacy appears as s/he laughs evilly and Zoey trembles. "Steve Smith is gone! You will never see him again!"

"Not again! I knew this would happen!" Zoey shouted.

"Lucy is too powerful. Stacy can never go away! Sorry Zoey! Steve Smith is gone!" Stacy laughs evilly.

"NO!" Zoey cries as a tear falls to the ground.

"Zoey, listen to me!" we see light shadows of Meg, Eddie, Jeff, Hayley, Mark, and Adaline.

"You are in charge!" Eddie said.

"You are a light girlfriend! A force for good!" Hayley added.

"Yeah, you can kick the evil's ass!" Jeff shouted.

"We're here for you Zoey!" Mark cheered.

"We'll be here no matter what" Meg commented.

"We believe in you!" Adaline encouraged.

"Steve Smith is not Stacy Smith!" Eddie added.

"No, he's not because he is...Steve Smith! He is my boyfriend and will remain to be my boyfriend!" Zoey roared at the sky as she quickly helps Steve crossdress to become...Korra from The Legend of Korra.

"Now, watch this!" Zoey puts on...an Aang costume from Avatar: The Last Airbender. "I need this" she dons a bald cap to look like the Avatar.

"No! You guys look like the opposite gender! It's not fair! No! I wasn't ready!" Roger cried. "Hey wait a minute, what about dressing Steve as a sexy blonde girl?" Roger snapped.

"Like this" Steve removes his Korra wig, revealing a long blonde hair wig and removes his costume, revealing black lingerie. The audience cheers super loudly.

"I win!" Zoey smiles as Roger kneels down.

"No! Okay fine, they're not really dead!" Roger confessed as they were revealed to be trapped in the floor in a backdoor.

"The dead bodies are actually dolls and the blood is actually cherry KoolAid.

"Babe, I was just having the strangest dream. I dreamt that we were trapped from some menacing phantom. Oh wait, was it real life?" Jeff appeared.

"I'm too scared to eat" Bethany complained.

"I'm always hungry" Barry commented.

"Kore wa damudatta (this was dumb)" both Toshi and Lindsay said in unison.

"Hi Steve! Hi Zoey. Wait a second? Is Aang cheating on Katara with a hooker?" Hayley asked as everyone laughed.

"Hayley, let me explain: I didn't want to join the contest because I feared that Stacy would be back, but now I'm cured from my trauma, thanks to Roger" Zoey said as she removes her bald cap to reveal her light blonde hair again.

"Good for you Zoey!' Meg cheered.

"Guys, I need to confess: the costume contest was my idea! Nobody approved it but you listened to this Eddie guy instead by which...hi Eddie, I'm Roger. Nice to meet you" Roger shakes...Meg's hand.

"That's Eddie" Meg points at Eddie as Rey.

"Hi Eddie, I'm Roger and nice to meet you" Roger introduced himself.

"Nice to meet you" Eddie said.

"Roger, I'm sorry we didn't approve of your idea but approved Eddie's instead, even though it was the same idea. You know what? I have an idea" Meg said as she and Eddie approached to the audience.

"Ladies and gentlemen, the master of ceremonies of the Halloween party is...Roger Smith!" Meg announced as the audience cheered for him.

"So who won the costume contest?" someone asked.

"The winner is...all of you!" Roger announced as everyone cheered super loudly.

"Now what?" Hayley asks.

"Let's boogie!" Zoey cheered as she dons her Aang costume once again, along with Steve wearing his Korra with blonde hair costume as the friends dance to Monster Mash.

"This is the best Halloween ever!" Eddie and Meg cheered in unison.

(A/E But tomorrow's Thanksgiving...oh what the hell? Simpsons air Treehouse of Horror on November sometimes so it's all good.)

"Thanks for not turning into Stacy" Zoey said.

"No problem babe" Steve said as he was about to kiss Zoey, but stopped.

"Uh, would it be weird for Aang and Korra to kiss?" Steve paused.

"I have an idea" Zoey dragged Steve into the bathroom and left their costumes outside.

The End

My apologies for an extremely long delay. I've been extremely busy but I'm back now. Thanks to aldovas for this crossover and I hope you enjoy it, despite Halloween being over a couple of weeks ago.
