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.

Siblings of Doom! contains examples of:

  • 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.
  • 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.
  • Advertisement:
  • 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.
  • Crossover Couple: Word of God says that this will happen between Lincoln and Gaz.
  • 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 stupidy 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.
  • 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?"

How well does it match the trope?
