Ideas for a Little Nightmares crossover fanfiction?

One idea could be a crossover with 'Alice in Wonderland'. The protagonist of Little Nightmares could fall through a distorted mirror and end up in Wonderland. They would encounter the strange creatures there, but with a Little Nightmares' twist of horror and mystery. For example, the Cheshire Cat could be a more menacing figure, with a dark aura and a creepy smile that reveals sharp teeth.

A cool plot could be a character swap. Imagine Frisk from Undertale in the world of Little Nightmares. Frisk's determination would be put to the test in the nightmarish setting of Little Nightmares. They would have to face the Janitor and the Twin Chefs just like Six does. Meanwhile, Six could be in the Underground, dealing with Flowey and Toriel. The contrast in the two worlds' aesthetics and challenges would make for an exciting story.

A more heart - warming fanfiction could be a story where the characters get a moment of peace. Imagine if there was a hidden corner in the world of Little Nightmares where the characters could relax. Six could share her food with the others, and they could all have a brief moment of camaraderie, forgetting the horrors that surround them for a while.

Well, you could write a fanfiction where the stomach growl of the character attracts the attention of a friendly but strange creature. This creature could help the character find food in exchange for something. For example, the character might have to solve a riddle for the creature.

First, decide which two universes you want to cross over. For example, if it's Little Nightmares and Alice: Madness Returns, study the lore and characters of both. Then, create a scenario that brings the characters together, like a strange portal opening up.

An OC could be a former cook in the Maw who has a change of heart. The fanfiction could explore their journey of redemption as they help the other children. They might have knowledge of the Maw's layout and use it to their advantage.

One idea could be exploring the backstory of the Thin Man. Maybe he was once a normal child in the world of Little Nightmares but something happened to turn him into that terrifying figure.

The color palette of both can be combined. Little Nightmares has a lot of dark, muted tones, while Undertale has more bright and distinct colors in some areas. In the crossover, you could have the dreary halls of the Maw tinted with a bit of the purple glow from the Underground. For the characters, Six's ragged clothes could be contrasted with Frisk's bright blue and purple striped shirt. You can also blend the spooky nature of Little Nightmares with the somewhat comical but also menacing aspects of Undertale, like making the Janitor have some of Sans' laid - back but dangerous attitude.

First, decide on the two universes you want to cross over. For example, if it's Little Nightmares and 'Silent Hill'. Then, think about how the main character from Little Nightmares would end up in the Silent Hill world. Maybe they get lost in a strange fog and suddenly find themselves there. Next, introduce the elements of Silent Hill, like the rusty and desolate environment, and start building the conflict. Will the character be hunted by the creatures from both universes? That's how you can start.

One idea could be exploring the backstories of Six and Seven. Maybe Six had a family before ending up in the Maw and how that affected her journey. For Seven, we could imagine his adventures before meeting Six. Another idea is a time - travel fanfic where they go back to change certain events in the Little Nightmares world.
