There's a little bit of 975 in everybody.
"There was some things Man was not meant to know, but what would it be of any luck that the next horror came from such a small, innocent town known as Royal Woods? The Loud Siblings are now forcibly thrust into the life of such horrors when they became them, Lincoln's sisters and brother was captured by the SCP Foundation, and with his friends and allies, they will know...of SCP-975."

The SCP-975 Files
is a crossover between The Loud House and the SCP Foundation written collaboratively between EliteSlayer103 and Timothy D along with a few others, which was published on December 26th, 2019.
The SCP-975 Files provides example of:
- Adaptational Sexuality: Several of the characters in the story have been made bisexual and etc, such as Ronnie Anne being in love with Sid and Lincoln.
- Ascended Extra: In the Loud House show itself, Kat is a background character usually limited to cameos and only have two lines of dialogue in total throughout the entire show. Here, she is not only a central character, but also actively trying to free the Louds from captivity.
- Audience? What Audience?: While Lincoln explains to the readers How We Got Here, Sid just sees him talking to a wall.
- Asshole Victim: There was so far two people that the Loud siblings have personally killed for their vendettas, namely Chandler and Lord Tethersby.
- Ax-Crazy: A few of the SCP, but Lynn, Luan, and Kat stand out in particular.
- Badass Pacifist: Chris isn't exactly prone to murder or violence as an infected and would rather convert a person to their side, but his mutation allows him to assist his fellow infected without needing to get violent, that is, unless its someone that truly deserves it.
- Berserk Button: Luan is incredibly protective of Lio and it is a bad idea to hurt them in her presence. Agent Stone learns this lesson the hard way.
- Bizarre Alien Biology: 975 Infected outwardly look human save for the fact that they lack any internal organs, the uncanny ability to swap between their regular eyes and their new ones, as well as their human teeth becoming needle-like in appearance on demand. This lack of any substantial organ function means they cannot be killed by means that'd kill regular people. Along with their blood becoming highly infectious and their main means of transmission is vomiting on their victims.
- Blue-and-Orange Morality: It would be a stretch to call the infected Louds or the ones they infect evil since they personally target mostly either people that personally have their ire or criminals, with civilians being a toss up, since Lynn ignores easy to kill bystanders to defeat SCP-096 suggests their infection overwrites how a human morally understands a situation with something less restrictive, like killing as a solution to a problem, or subversion.
- Body Horror: Kat has the power to induce this in others by changing the chemical makeup of their body. She uses this to great effect when torturing an SCP operative into revealing the location of the captive Louds.
- Lio's 975 Mutation essentially allows him to mimic qualities similar to The Thing, yes THAT The Thing, being able to twist and distort his body to attack people.
- Regular Humans when infected by SCP-975 don't exactly have a fun time when they are turning into a new instance as explained below.
- Eldritch Abomination: It wouldn't be an SCP Crossover without hundreds of these running around or currently contained.
- SCP-975 initially is a mass of black barely sapient sludge that is surprisingly resilient and strong enough to overpower Lynn of all people all to force itself into her body and begin infection, though that is just the least of its capabilities.
- Hero Antagonist: The SCP Foundation is generally this in the story, being dedicated to keeping humanity safe from every kind of threat set to destroy them or take over, this well-meaning but very pragmatic and ruthless attempts to safeguard mankind inevitably draws them into conflict with the 975 Louds.
- Humanoid Abomination: What results from when SCP-975 infects a victim.
- It essentially melts down every internal organ in their body (except their bones and muscles) and converts it all into more 975 Fluid. They are then connected to the Hive Mind network of whoever the 975 Infected defers to the most, all while being subtly compelled to add more people to their network by forceful conversion.
- Not only that, these infected possess Super-Strength proportional to how physically active they are (for reference, Lincoln who is not the most active person can throw cars like toys), a Healing Factor that allows for From a Single Cell as long as there is a piece of 975 infected tissue or fluid to regenerate from, high-pain tolerance and Super-Toughness.
- The most dangerous capabilities the 975 Infected can have is their personality influenced Superpower Lottery that makes fighting them as a whole a nigh impossible front.
- Sizeshifter: Lori's mutation has the ability to grow between her default height to giant proportions and greater.
- To compare with Maddie and Ant, who can grow and shrink themselves.
- Smarter Than They Look/ Took a Level in Badass: Lio is introduced as the incredibly introverted and nervous twin of Lincoln, often going into fight or flight mode when encountering anyone outside of their family. However, they are also clever enough that they not only manage to escape the SCP Facility, but also evade the Foundation long enough to reunite with Lincoln.
- The Power of Apathy: A weaponized version of this trope, used by Maggie as an ability to project a Apathy inducing aura that would debilitate and eventually incapacitate her victims along with being able to create simple hard-light weapons that can specifically induce apathy.
- You Are Who You Eat: Being that Lio is essentially The Thing, Lio absorbs the memories and personalities of every person they eat. Taking things further, Lio can swap between the forms of the people they’ve eaten and can even create clones of themselves through infecting potential converts with their cells.
