Siblings of Doom! is a crossover fanfiction story by author Mr Dusk featuring characters from The Loud House and Invader Zim.

After the Loud Family's house is destroyed in a tornado, the Louds move to another city to start their life anew. Unbeknownst to the family, their new home is located within close proximity to the Membrane family and Irken Invader Zim, who - upon learning that humans are commonly known to have siblings - immediately tries to rectify his apparent familial deficiency. Meanwhile, Lincoln astonishingly befriends Gaz while Lisa ends up transferring into Dib's classroom.

The story is being translated into Spanish.


Siblings of Doom! contains examples of:

  • All for Nothing: Dib joined the Swollen Eye Network in the hopes that he would eventually be able to gain recognition and respect from the ones that mocked him all these years. Only to be told by Agent Darkbootie that the whole point of the network is to be treated like crazy people, and as long as he works with them he'll always be treated like the 'weird kid'.
  • Alternate Universe Fic: Where the Loud family's house was destroyed by the tornado in “Homespun" rather than surviving it, forcing them to move to a new home.
  • Apathetic Teacher: Mr. Elliot is a minor case as while he's kind to Lincoln and seemingly optimistic, he completely fails to notice a child freaking out and jumping out of the classroom or Gaz and Lincoln playing games all day.
    • Lori's teacher is a more blatant example, spending the entirety of her class sleeping.
  • Ascended Extra: Minimoose, whose small involvement in the plot is significantly more than his (lack of) appearance in the Invader Zim cartoon.
  • Best Her to Bed Her: Lincoln unintentionally does this to Gaz during their first encounter, sparking their one-sided rivalry.
  • Advertisement:
  • Belligerent Sexual Tension: Between Gaz and Lincoln in A NEW CHALLENGER APPROACHES PART 2, bordering on flirting on Gaz’s part.
  • Bullying a Dragon: Lola and Lynn learn the hard way not to antagonize Gaz, though Lynn continuously fails to realize this.
  • Charles Atlas Superpower: Gaz effortlessly tosses Lynn out of the house when she interrupts her and Lincoln-twice.
  • Composite Character: Mr. Eliot turns out to be the human form of Señor Diablo
  • Cool Big Sis: Lori ends up giving Lincoln warm advice to deal with Gaz.
  • Curb-Stomp Battle: Professor Membrane, once he realizes that there is a giant robot destroying the city outside he easily defeats it with a push of a button.
  • Death Glare: Gaz shoots Lola a mean one when she off-handedly calls her a weirdo.
  • Deconstruction Crossover: Of the Crapsack World Invader Zim takes place in, with the Louds (who are from a slightly more realistic setting) being constantly beffudled by the insane amounts of apathy and stupidity shown by everyone around them.
  • Doomy Dooms of Doom: The title, of course; featuring Invader Zim.
  • Everyone Can See It: Or at least Lucy can see that Gaz is falling for Lincoln.
  • Fictional Counterpart: The names of the video games mentioned in Chapter 4 are all based on actual video games.
  • Girls Love Stuffed Animals: Gaz has a plushy on her bed that looks like Lincoln.
  • Insane Troll Logic: Zim's impetus to create robots that could stand in as siblings for his human disguise came about after observing the Loud siblings and misinterpreting their large number of children as being common for human families.
  • The Knights Who Say "Squee!": Lisa is clearly ecstatic upon realizing that Gaz and Dib are the children of Professor Membrane, much to the chagrin of Gaz.
  • Lampshade Hanging: When Rita hands Lily over to Leni after she accidentally dropped one of their moving boxes filled with fragile stuff, we get this quip from Lisa Loud:
Lisa: "...she can't be trusted with fragile objects but she's trusted with a toddler?"
  • Love at First Punch: Strongly hinted that Gaz started to have feelings for Lincoln as a result of him repeatedly beating her at games.
  • Love Confession: Lincoln tells Gaz that he likes her at end of chapter 23.
  • No Challenge Equals No Satisfaction: Discussed. Lincoln considers throwing a game to make Gaz feel better, Lynn points out how this would infuriate her more then losing.
  • Noodle Incident: In the second minisode, Luan is told of various incidents that occurred in the High Skool, resulting in the ban of novelty gags, mime makeup and squirrel jokes.
  • Normal Fish in a Tiny Pond: Leni may not be smart by any stretch of the imagination, but being able to open a door makes her a genius compared to the other girls at her high-skool.
  • Odd Friendship: Between Lincoln and Gaz, starting with Chapter 4.
  • Paper-Thin Disguise: As in Invader Zim, Zim passes off as human using a wig and contact lenses. GIR’s green dog suit doesn’t fool Lana, who realizes that he’s a robot, though she thinks nothing of it after Leni showed GIR to her.
    • In chapter 6, Lisa reveals that she saw right through it, much to Dib's astonishment.
  • Selective Obliviousness: Zim has managed to convince himself that the events of the movie never happened. As far as he is concerned his mission is real, the Tallest weren't trapped in a Florpus hole along with the entire armada and they will arrive someday soon to reward him for his efforts.
  • Shipper on Deck: Lori tries to set up Lincoln and Gaz.
  • Shout-Out: Features a brief mention of Nailbunny, from Jhonen Vasquez's earlier work, Johnny the Homicidal Maniac.
    • Johnny himself (going by Mr. Nny) later shows up as Luna’s art teacher. Noticeably he’s one of the only adults that’s good at his job.
    • Also a brief one to the Powerpuff Girls and My Life as a Teenage Robot.
    • Remina the Hellstar, a half-demon, half-cosmic horror sent by Señor Diablo to help Lincoln train with his new powers, is named after the title character of Hellstar Remina. It is even lampshaded:
      Lucy: Is that a reference to something?
  • Show Within a Show: Lily, GIR, and Minimoose watch Floopsy Bloops Shmoopsy in the first chapter.
  • Stunned Silence: Lincoln, upon realizing that Zim is an alien and that he lives across from their house.
  • Sucky School: The Skool that Lincoln goes to, also the High Skool and Middle Skool that his older sisters go to.
  • Took a Level in Kindness: Lynn; invokedWord of God says that his immense dislike of Lynn in the show compelled him to tone down her less unlikeable traits and to improve her character in a way that the show seems to refuse.
  • Unexpected Successor: Zim is next in line to become Tallest as dictated by the control brains, but his placement on the line at all was nothing but a joke by red and purple, and he is so far down the line that the only way he could succeed as the Tallest is if all of the hundreds of other Irkens ahead of him were either all sucked into a Florpus holenote  or were officially his subordinate and thus now behind him in succession.
  • What the Hell, Hero?: Darkbootie chews Dib out for having Tak's ship and not only not reporting it but using it for travel himself, and for involving the Louds. He tells the boy bluntly that the Swollen Eye Network was never going to help him get the fame and praise he thinks he deserves. This job isn't going to make his peers stop laughing at him, in fact, it will 'encourage' it to keep up the Masquerade, and he needs to ask himself if he's willing to step up and put the world over his need for people to like him.
