Louds vs. the Forces of Evil is a Star vs. the Forces of Evil and The Loud House crossover written by Ninjamon1228

Watch as the princess of Mewni Star Butterfly goes to live on Earth with a certain white-haired boy and his massive family. Lincoln's life is about to get a whole lot crazier, but luckily he's down for it as he, Star, his family, and friends he has now and meets along all take on whatever lies ahead all the while still having a good time!


Louds vs. the Forces of Evil provides examples of:

  • Adapted Out: The Box of Truth isn't used due to the presence of Hekapoo, who, recognizing what it is, chucks it into a dimensional portal.
  • Adaptational Badass: Unlike Marco, Lincoln isn't really a fighter. However, he later gains fire and Ice powers in the vein of Shoto Todoroki.
  • Adaptation Relationship Overhaul: In canon, Star develops a huge crush on Marco. While you would normally expect this would translate to a crush on Lincoln here, instead she begins to develop a crush on Jackie.
  • Adaptational Sexuality: In canon, Leni Loud has a boyfriend, and Carlota had an ex-boyfriend. Here they are dating each other.
  • Affectionate Nickname: After becoming friends with Hekapoo, Lincoln starts calling her H-Poo, like Marco. Much to her annoyance.
  • Age Lift: The Loud House characters are aged up by three years.
  • Advertisement:
  • Ain't Too Proud to Beg: Hekapoo certainly isn't shy about doing so when Toffee is about to crush Lincoln.
  • All Men Are Perverts: Star tells Hailey that all guys have a perverted side when they catch Lincoln checking the disguised Hekapoo out during class. An interesting case since neither is bothered by this since Star considers it perfectly normal and Lincoln, unlike Rusty, doesn't let it control him, while Hekapoo is "pleased" that Lincoln finds her that attractive.
  • The Bet:
    • Lincoln doesn't go on a decades-long quest to beat Hekapoo's challenge like Marco. Instead, he bets her that he can prove that humans and Earth aren't boring by just his hometown alone. If he wins she gives him back the scissors she reclaimed. If she wins then she gets the satisfaction of being proven right that humans are worthless. He wins.
    • Rusty bet Zach that the new student Hailey had F-cups. He wins.
  • The Beastmaster: Out of all of the siblings, the laser puppies bond closest with Lily, who can order them around enough that they'll attack someone on her command.
  • Blind Musician: Lincoln's friend Terry is a blind street musician.
  • Break the Scientist: When Lincoln introduces Star to his family, by using her intro no less, Lisa scoffs and (as expected) dismisses the idea of her being a "magical princess from another dimension", and magic in general. Until she creates her laser puppies, per Lily's request, leaving the family, but most importantly Lisa, unable to process what they just saw. The final nail was when she used her Sparkle Glitter Bomb Expand spell to turn the attic into her new room, resulting in the little know-it-all's brain to shut down. After which she refuses to be involved with anything related to Star's magic.
  • Calling Your Attacks: Still being the geek he is, Lincoln calls out attacks when using his powers.
  • Casanova Wannabe: Rusty, one of Lincoln's friends, thinks he's a lady's man, constantly flirting and hitting on multiple girls, usually ending with him getting smacked. Even when Star goes crazy from mewberty, and was cocooning every single boy in school, she tosses him aside like a piece of trash. What's REALLY pathetic, is that he WANTED her to cocoon him.
  • Character Development: Everyone from the Loud side of the crossover is three years older and like in reality, not everybody remains the same person they were when they were kids.
    • Lori is noticeably more chill, now that she's not the one in charge of her younger siblings.
    • Lincoln has picked up a few new skills since he was eleven. He's able to play the guitar and sings well enough to draw a crowd.
    • Rusty is no longer a kid just starting puberty who thinks he's a lady's man, he's a teenager in full swing of it and has only gotten 'more' unpleasant for girls to be around.
    • In "Mewnipendance Day", Hekapoo shows the same narrow-minded bigotry towards monsters, as she does in the show. Not only thinking all monsters are evil, but also claiming humans aren't capable of doing anything bad... until Lincoln gives her a history book on Adolf Hitler. After reading a few pages, she's so shocked she dunks her head into a lava pit to muffle her horrified screams. After Lincoln talks to her about keeping an open mind, she starts to question her beliefs.
  • Child Prodigy:
    • Deconstructed. Lisa is an exaggeratedly intelligent child genius who has been a Nobel prize-winning scientist who regularly gives lectures at local universities, but has little in the way of social life or a life in general outside of her experiments. Even an unparalleled genius needs to have fun outside their work every once in a while.
    • Downplayed. Lincoln is the second most intelligent person in his house after Lisa, but given the sheer gap in intelligence between her and most people, it would be more accurate to say he's the smartest 'regular' member of the family.
  • Covert Pervert: Lincoln was embarrassed to admit he spent a lot of math class staring at Hailey/Hekapoo's backside and asks Star not to tell her. Though Hekapoo already knew that and was fine with it since she was teasingly encouraging him to do so.
  • Distracted by the Sexy: Lincoln finds it hard to concentrate in class after a disguised Hekapoo joins and he can't stop himself from staring at her behind. Not that she isn't pleased to find out he was.
  • Elemental Powers: As a result of Star trying (and succeeding) at fixing his broken arm, instead of a monster tentacle he gains elemental powers that, once he accepts them as a part of himself he gains control of.
    • Playing with Fire: First Lincoln gains the ability to generate and manipulate fire with his left hand. Stars' attempt to put it out with another spell resulted in him gaining...
    • An Ice Person:...Ice powers in his right hand.
  • Everyone Can See It: It's obvious even to Leni that Hekapoo and Lincoln are romantically interested in each other. The only ones that don't see that they're more than friends are Lincoln and Hekapoo themselves and even then even they aren't sure they mean it when they say they don't like each other like that.
  • Everyone Has Standards: While going through mewberty, Star goes boy crazy and start's webbing all the boy's in school to the walls. All but Rusty, who actually 'wants' her to cocoon him. But even in her state, she's not interested in a womanizing creep like Rusty. So she tosses him aside and ignores him.
  • Fantastic Racism: Hekapoo starts to realize her hatred of monster is this, especially after she starts seeing the parallels with regular racism from the history books she's reading.
  • Gag Boobs: Hekapoo asks an ogling Zach and Rusty if they've never seen a girl with F-cups before.
  • Green-Eyed Monster: Everyone in Lincoln's class turns into this when Hekapoo joins the class in her Hailey disguise. The girls get jealous over her looks, while the boys get jealous of Lincoln when she pays attention to Lincoln...and Lincoln when other boys keep ogling her.
  • Heel Realisation:
    • When Lisa joins Star and Lincoln's trip to Father Time's realm in Freeze Day, and they see her past in the monitors, Star is quick to call Lisa's life "Boooooring". And the worst part, Lisa agrees. Despite her dedication to science, seeing her do the same routine of test, study, and experimentation, has left her life hollow and dull. Compared to all the adventures her brother goes on, and the fun activities her sister's do. This is why she now tries to loosen up and have more fun, and study less.
    • When Tom tries to pull his stunt with Mr. Candle this time, he doesn't have the benefit of a heart to heart with a sympathetic ear, but is threatened with holy violence by Jackie into telling Star the truth, resulting in him hurting Star far more and him feeling terrible for putting her in this position.
    • When Hekapoo helps Lincoln, Star, and Lana babysit Buff Frog's kids, she ends up having several flashbacks to her time raising Queen Festivia, and how she essentially manipulated the girl she'd raised like her own daughter into becoming a drunk to get her to wage a war against monsters, then yelling that she regrets raising her after the girl sobered up enough to realize it was wrong. This, combined with her realizations regarding her own bigotry, force her to acknowledge that she's been a pretty terrible person.
  • Hidden Depths: In the years between since he was eleven and the present, Lincoln has learned to play the guitar and sing. He admits he's not as good as Luna or his friend Terry, but that doesn't mean he's not good. Just ask Hekapoo.
  • Hulking Out: Star's mewburty form doesn't just appear once then never again. After it appears the first time Star will start to 'go purple' in times of great stress. When confronted by the knowledge that she doesn't get to choose her own future Star starts to turn back into a giant moth.
  • Humans Are Special: Instead of going on a quest to hunt down clones, Lincoln is challenged by Hekapoo to prove to her that humans aren't worthless. He wins.
  • Hypocrite: Star claims that All Men Are Perverts to at least some degree to Hekapoo, while in her canon show she went wall-eyed staring at adult Marco's abs.
  • I Am Not My Father: Star's worst fear is becoming like her mother, a stern, emotionless, dull woman. As shown in "Royal Pain", when Star has had it with her father staying with her and tells him to leave. To which she sees her reflection as mistakes herself for her mom. She becomes so distressed at this that she has a panic attack, and has another purple episode.
  • Immortal Immaturity: Hekapoo is centuries old at least and a Time Abyss at most. However physically and mentally she is a teenager.
  • Insistent Terminology: Hekapoo flirts with Lincoln because she likes to tease him, not because she's falling in love with him.
  • Lap Pillow: One of the ways Hekapoo enjoys teasing Lincoln is by sitting in his lap.
  • Lady Drunk: To Hekapoo's regret she had allowed Festivia to turn herself into a drunk so that she was easier for the MHC to manipulate.
  • Like Brother and Sister: Star very quickly finds herself being treated like just another one of the Loud sisters, and Lincoln like a close brother. So much so she's creeped out when Mr. Candle asks if she has a crush on him or Jackie.
    Star: What no! Lincoln is like a brother to me. And dating your brother... um gross.
  • Like Father, Unlike Son: Star has nothing in common with her mother Moon, and has no interest in being queen. It's even fleshed out more during Lincoln's therapy session on how much she resents her mother for being so strict. And her trying to force her daughter into being a "proper princess" hasn't improved their relationship either. Star even thinks her mom hates her for who she is.
  • Likes Older Women: Hekapoo is at least over 10,000 years old. This however doesn't unnerve or make her any less attractive to Lincoln. Then again it probably doesn't hurt that despite her age Hekapoo looks like a pretty teenage girl anyway.
  • Logical Latecomer: This fic takes place a few years into the future, where Lori has moved out to go to college. She comes back to visit her family to find that the homestay they took in was a magical princess from another dimension.
    • The same with Ronnie Anne and Carlota several chapters prior.
  • Mood Whiplash: Lori is excited to hear about Lincoln's new 'female friend', then she actually meets Hekapoo, and her approval of the girl drops like a lead weight.
  • Ms. Fanservice: Hekapoo is already the series's HOTTEST girl (figuratively and literally). So her 'Hailey' human form pretty much reduces the boy students into drooling pigs, with Rusty even betting her bust size.
  • Mythology Gag: In the first chapter, Lincoln quotes his show's theme song.
  • No-Sell: Hekapoo tries to give Lincoln a burnt bald spot like with Marco. But due to his new powers making him fireproof, she can't burn his hair.
  • Not So Above It All: Lincoln once read Luna's diary on Luan's and Leni's prodding. His rocker sister and her girlfriend pranked them as payback.
    • Lincoln doesn't want to be thought of as one of those guys who just ogle girls, but even he finds himself staring at Hailey/Hekapoo during class.
  • Nothing Is the Same Anymore: Hekapoo can't stop thinking about what she's been learning about discrimination on Earth and comparing it to the monster situation on Mewni. The problem is that Hekapoo has had her mind made up about this subject for at least several centuries. So it's hard for her to accept changing it.
  • Not So Stoic: Hekapoo tries to play it off why she choose to go to school with Lincoln and Star, but a little prodding reveals she was seriously worried about Lincoln when he got kidnapped and nearly crushed and just wants to keep him safe.
  • OOC Is Serious Business: When Hekapoo see's Lincoln's about to be crushed in Toffee's cage, the tough-as-nails girl is reduced to tears and begs the lizardman to let him go, taking Toffee by surprise.
  • Paper-Thin Disguise: Hekapoo's human 'Hailey' form looks exactly like her minus (most) of her inhuman traits.
  • Parental Substitute: Hekapoo raised Festivia in leu of her real mother. She now realizes she did a terrible job.
  • Past-Life Memories: The time monitors in father times dimension show Lincoln memories of his past lives. Which all involve the past Butterfly Queens in some manner. The images are familiar to him, but he doesn't actually remember any of this as the room was showing him images from his timeline, not his memories.
  • Poor Communication Kills: Subverted. Lincoln explains everything about why he had the scissors to Hekapoo the first time they meet and is willing to just hand them over without a fight since they do actually belong to her, giving Hekapoo a better first impression of humans far quicker than Marco had. Though only just, as she still needs convincing before she considers humans as anything but magicless meat-wads.
  • Related in the Adaptation: Jackie and Sam are cousins.
  • Reincarnation: There are strong hints that Lincoln's fate has, throughout his past lives, always been intertwined with the Butterfly families. He hears about a white dragon that destroyed their original spellbook, and Celina the shy's epitaph mentions an 'orange prince' as her love. When the monitors in father times dimension focus on him, they show him points in his previous lives that involve members of the Butterfly queen stretching back centuries that he has no memory of. When he first meets Glossaryck, it's mentioned how he finds his laugh strangely familiar, and when when Celina is briefly brought up, Glassaryck simply states that he "doesn't need to tell [Lincoln] that", implying it's something Lincoln already knows.
  • Say It with Hearts: Hekapoo might not notice that her flame has started to take the shape of a heart whenever thinking about Lincoln, but Leni certainly has.
  • She Is Not My Girlfriend: Lincoln and Hekapoo insist their just friends and don't have feelings for each other. Nobody buys this for a second.
  • Shipper on Deck: The second Star see's that Lincoln and Hekapoo are close friends, she makes it her mission to hook them up. She even already has a shipping name for em, "Lincapoo". His sister's aren't far behind upon meeting her, sans Lori.
  • Ship Tease: Lincoln and Hekapoo are so obviously interested in each other that nobody believes it when he says she isn't his girlfriend. Going much slower and much more unsure about their true feelings for each are Star and Jackie.
  • Shout-Out:
    • Lincoln's teenage appearance is based on Future Trunks from Dragon Ball Z. With the same ponytail hairstyle and orange jacket.
    • Lincoln gains powers like Shoto Todoroki, but when he uses his ice powers his skin darkens like Gray Fullbuster's.
      • Linc's arc in that chapter is similair to Finn and the grass sword.
      • During that chapter, Linc accidentally shoots a bird with a fire ball. Lily's response?
    • Chapter 11 is named and based on the Adventure Time episode "Card Wars".
    • In "Louds on Mewni" after Lucy and Janna buy a demonic book, the storekeeper asks if they're witches, to which they answer yes. So he lights a torch and plans to form a mob.
    "...Welp, time to round up a mob."
  • Stalker Without a Crush: Toffee is revealed to have a file on Lincoln, going as far back as his childhood.
  • The Tease: Hekapoo does enjoy making Lincoln sweat in this way. Though how much of it is 'just' teasing is up for debate as she admits to liking the idea of Lincoln checking her out.
