Hello hypothetic readers. Welcome to my first fanfic.

It took me a long time actually do this but it's happening. I had this idea for an episode of HA! and I just had to share it.

It's post-TJM and Arnold and Helga have been publicly for a while (for how Helga came around to the idea, read "Couples Only" by Cre8ivelybankrupt87, I love it but it's not the story I'm telling)

This is only Chapter 1, there will more soon. Also, english is my second language so sorry for any grammar errors I may have left in.

"Hey Arnold" belongs to Nickelodeon


"The Succubus"- A Hey Arnold fanfic

Chapter 1

It was the first week of summer vacation in Hillwood. After surviving the 6th grade, the kids of P.S. 118 celebrated their hard-earned freedom. Five of them, Arnold, Helga, Sid, Stinky and Harold specifically, decided to go to The Kiska to watch the premiere of the new horror flick "Heather's feast"

"Ooh. Can't wait to watch this movie!" Sid said.

"Right there with you, buddy!" Stinky followed.

"Y-yeah. So much… fun" Harold said, who was obviously scared of the idea of watching an R-rated movie, but he couldn't let anyone notice.

"What's the matter, pink boy?" Helga said in a mocking tone. "Chickenin' out?"

"Me? Hell no!" Harold answered.

"Harold, if you're scared just say it now" Arnold said.

"Ha! You'd like that. Would ya?" Harold said defensively "Well, it ain't happening!"

"Suit yourself, Tubby" Helga said as she rolled her eyes at her chunky friend

The abrasive girl then approached the box office and put her game face on, ready pull off a deception.

"Five tickets to "Planet of the Pies", please" she said innocently as she handed over the money.

"Huh? I'm confused" Stinky said "I thought we came to watch... Ouch!"

Stinky wailed as Helga had stepped over his foot to shut him up. Luckily for them, the clerk didn't suspect anything and gave them the tickets so they moved along.

"Damn it, Stinky!" Helga yelled in anger "You almost blew it! Don't you remember the plan?"

"Oh! The one in which we buy tickets to another movie and then we sneak out" said the simple country boy as he realized his mistake. "Yeah, I forgot".

Helga hit Stinky with a glare, while fighting the impulse to choke him.

"Yeah, well once again Helga saves the day" the angry tween snarked snidely. "Now move it, dweebs! We have to get snacks before the movie begins!" she commanded as they ran to the lobby.

After sneaking into the room projecting "Heather's feast", the kids picked their seats and waited for the movie to begin.

"Hey Football Head, don't you dare to pull a "yawn and reach" on me" Helga said to her long-time-crush-now-boyfriend Arnold "Just because we're thing now doesn't mean you can get handsy"

"Okay. But don't ask me to hold you when something scary happens" Arnold said, having learned to match her mean-spirited wit.

"As if!" Helga replied "I don't need excuses to hold my man"

As both continued their playful bickering, the boys seated at their left sighed in annoyance.

"Oh boy" Sid whined "Here we go"

"The Arnold and Helga routine" Stinky said, already familiar with the couple's dynamic "Prepare for a sickening mixture of flirting and fighting"

"Why did she come anyway? We invited Arnold and she acts like she runs the show" Harold complained.

"It's like she is Arnold's shadow. She goes wherever he goes" Stinky explained.

"Well I don't like it" Harold continued "Ever since those two became a couple, we get more Helga of I can take"

"What does Arnold see on her?" Sid wondered, as he found his friend's choice of partner very puzzling.

"Hush, you guys. The movie is about to begin" Stinky whispered while the screen went dark.

Skip an hour into the movie. We see the titular Heather, a beautiful cheerleader, and Steve, the handsome jock, in a car. They drive into a secluded part of the woods, specifically the make-out point.

"Some night we got there, Heather" Steve said "Fresh air, clear skies…"

"And not a single soul in miles" Heather said in a seductive tone "We can do whatever we want"

Steve gulps at this comment "Oh yeah?" he said trying not to lose his cool "What… do you have in mind?"

"Well, my top feels very tight? Mind if I take it off?" the blonde knockout said.

"Ugh… No! Not at all! Go for it!" Steve said eagerly.

Heather proceeds to do just that just to reveal a huge pair of breasts covered by a devilish red bra. Steve (and every male in the theater) gawks at the view.

"Yowza!" Stinky exclaimed.

"Hey Arnold" Sid whispered to Arnold "Check out those knockers". He got no reply.

Confused on why his friend was ignoring him, Sid turned his head just to see Arnold making googly eyes at Helga, while the two fed each other popcorn and giggled. For all of Helga's animosity towards PDA, the young couple could get really corny if given the chance.

Grossed out, Sid turned back to the movie.

"Do you like what you see, Steve?" Heather asked.

"Oh yeah! Very much so!" Steve replied.

"Prove it"

As Heather closed her eyes and pressed her lips, Steve did the same expecting a sweet and tender kiss. Unfortunately for him, the moment he closed his eyes, Heather opened hers. But they weren't blue and innocent no more. They had turned blood red and her mouth widened to reveal scary sharp teeth. The ominous score of the movie let everyone know what was coming just as Heather sank her teeth into Steve's gorgeous face, which made for a very effective blood fest.

Harold's reaction was expected. He jumped, let out a loud scream, and hid under his seat while crying for his mommy. For their part, Arnold and Helga instinctively held each other, not even bothering to think what the other wanted.

When Heather finished cannibalizing her date, she got out of the car, covered in blood, and said "I'll give him this. He knew how to take a girl for dinner".

One hour and four murders later, the movie ends. The kids leave the theater

"Boy howdy, that was intense!" Sid exclaimed.

"You can say that again!" Stinky followed.

"I must admit it was a pleasant surprise" Helga admitted in a rare moment of humility.

"Yeah, it's one of the most original horror movies I've seen" Arnold said "Harold, what do you think?"

Harold just stood there, still in shock from what he just saw.

"Harold? Are you okay?" Arnold inquired.

"Me? Uh, yeah" Harold answered nervously "I just remembered that it's getting late. I don't wanna miss the bus" he said trying to steer the focus away from himself.

"Fatboy's got a point" Helga said "I'm not using the subway again. Not after the last time"

"Well, let's get going" Arnold said "This was great, guys. We'll see you later" he told Sid and Stinky as they will be taking a different bus (their houses are in a different area).

"See you, guys. Bye for now" Stinky said as he waved them goodbye.

Arnold, Helga and Harold went to the bus stop to wait the bus that takes them home. Inside the bus, Harold pulled Arnold to the side to talk to him without Helga noticing.

"Hey Arnold, you forgot to invite the guys to Rummy night on Friday" he whispered to the blonde kid, as he usually provided the house for the game.

"Uh, actually I'm calling it off" Arnold answered "I'm busy on Monday"

"What? But it's rummy night!" Harold exclaimed.

"I'm sorry, Harold. We can always reschedule"

"But why?!What are you doing on Monday?"

"Helga and I are going on a date"

"Ow! Come on, man! Can't you two be apart for one day?"

"Harold, calm down. We'll just have rummy night another night. It's no big deal" Arnold tried to reassure his friend.

Upset, Harold crossed his arms and mumbled to himself. Meanwhile, Helga decided to intrude.

"What are you two hens gossiping about?" she asked in her usual mocking tone.

"It's just a scheduling conflict on Friday. But we will figure it out" Arnold told his girlfriend.

"Well, you better don't cancel on me, Hair Boy. Or you can say goodbye to your surprise gift"

"Oh yeah?" he asked curiously "How surprising it is?"

"You'll drop dead. That's all I will say".

At hearing this, Harold's mind flashed back to the movie, specifically the gory killings performed by a sadistic blonde demoness. From there, Harold just spiraled into assuming the worst. But was he exaggerating?

"Well. Guess I'll wait. Unless I find out before you give it to me" Arnold said in a cocky tone.

"Oh, don't bother Shortman. You will never see it coming" she said even cockier.

Harold' eyes went wide as plates as he heard that last phrase, although in a more sinister tone than it actually was said. But it was enough to convince him. Arnold's life was in danger.
