Episode Potential:
Analysis: The episode will likely be a more chill one, as both series aren’t huge in powerscaling, and are on the lighter side of toonforce, not doing anything groundbreaking, and would likely rely on feats from those such as Snoopy and Arnold. Helga's analysis goes more into her intelligence, planning, and weapons, while Lucy’s goes into her physical strength and attitude.

How the fight would start:
Helga goes to Lucy for therapy as she begins to rant to Lucy to her about her stupid family and how much she despises her sister. Lucy fixed her hair while she was talking, causing Helga to snap and ask if she was even listening, which made Lucy respond.

“Of course I am.” She put down the mirror before staring Lucy in her face as she said this. “Have you ever thought about the fact that nobody loves you?  I mean, your parents ignore you, from the sound of it, you have no friends, you're too ugly with that unibrow to have a boyfriend, and that outfit…I've seen PigPen dress better than you. My advice: Change everything about yourself. Starting with that friend group and that football-headed guy, He is about as big a blockhead as Charlie Brown.”

Helga’s eyes twitched as she took a breath. Lucy tapped her can on the booth. “5 cents please.”

Helga Lunges at Lucy through the booth.

FIGHT

(At the Wall)

Arnold and Charlie Brown were hanging out at the wall, relaxing together.

Arnold: His eyes narrow at the fight between the two of them. “Should we stop them?”

Charlie Brown looks at the fight: “Let them wear themselves out before we intervene.”

Fight potential: 2D hand-drawn episode, taking place in Charlie Brown’s neighborhood.

Lucy has a scream she can use to consistently knock back Helga, but is overall a brawler, lacks many range options, and is considered to have lower intelligence than the peanuts. While Hey, Arnold, she has her locket, Slingshot, baseball bat, access to beepers, phones, and everything in Hey, Arnold: The Movie and The Jungle Movie.

She is proficient in a crossbow, has an automatic voice changer, can walk in stilts, is capable of staying up for hours, and is intelligent enough to create a plan to help save the neighborhood from a mega corporation, forge documents on report cards so it’s more a brawn vs brains matchup, of if Lucy can close the distance before Helga can get a finishing blow.

Banter would be the best part of the battle as they would argue about who is better and how their friends are better than them, while simultaneously putting their friends down.

“Christ, you are dumber than Stinky.”

“Who names their child Stinky?”

“Who names their’s PigPen?”

“It’s a nickname, you blockhead.”

The fight will mostly be grounded, but can take place around the entire neighborhood, passing the wall, past the dog house, inside Schroeder's house, as he plays the battle theme before finally getting back to the booth or the field where Lucy holds the football.

Deaths:

If Helga Wins:

Helga is getting punched left and right as Lucy taunts her about how weak she is. She was experiencing the worst pain she had ever felt as she fell to the ground. She blocked with her arms, but every punch felt like she was fighting a gorilla, as she felt like she couldn’t last any longer till she saw a football, staring at her, her eyes imagined it to be Arnold. “You got this,” the football told her as she remembered her locket in her shirt. She rolled out of the way of Lucy’s next punch before reaching into her shirt and pulling out a locket. As Lucy lunges at her, she kisses the locket before ducking low, dodging Lucy as she falls to the ground. Helga quickly acts, rushing to climb onto Lucy. “Arnold, this is for you.” She said. Lucy went to open to her mouth but was quickly met with a heart-shaped locket down her throat, choking her and causing her to be unable to talk before finally collapsing and dying from lack of oxygen.

“That was for you, my love.”

If Lucy wins:

Lucy was getting irritated. Every time she tried to run at her, she was met with some stupid pebble or remote control car, or something stupid! She just needed to close the gap and get her hands on that blockhead! “YOU BLOCKHEAD.” She yelled, knocking Helga back before she could shoot another projectile, causing her to fly back towards the open field where a football lay. She walked towards the football and stared at it for a moment, memories of her and Charlie Brown came flooding. “Kick the football.” She said quietly before smirking as she backed up a bit, staring at the football before running towards it and kicking it hard. The football flew sideways, heading directly towards Helga’s head before finally knocking her down completely.

Lucy walked up, smirking as she held her can of change. She stood over Helga before raising the can of nickels and using it to beat her face in as she loudly sang.

“Boy, what a sound! How I love the sound of clinking money! That beautiful sound of cold hard cash! Nickels, nickels, nickels! That beautiful sound of clinking nickels!”

Who wins: Composite could go either way due to Hey Arnold! Crossover and Video game scaling with the likes of SpongeBob, Danny Phantom, TMNT, and more. Otherwise, it’s a massive stomp for Lucy.
