SystemStuck, an outdated Summerstuck fic by LooneyMooney

Summary
Or, In which a formerly well-respected scienterrorist is outed as a mutant and leaves adult society, adopts a blueblooded wriggler, and begins a heretical quadrant-smearing courtship with a lusus with rebellion espionage training who himself unwittingly adopts three orphaned children.
Contains graphic depictions of dismemberment, death, heretical relationships, anti-imperial sentiments, and a juvenile understanding of how the non-conciliatory quadrants work. Not suitable for trolls 6 sweeps and under.I found this buried in my Google docs from like 2017 and thought yall might enjoy it?

Weapon and the Meister by LooneyMooney
Fandoms: Animaniacs, Pinky and the Brain, Soul Eater, Soul Eater Not!

Summary
When Pinky and the Brain get transferred from Acme Labs in Burbank, California, to Patchwork Labs in Death City, Nevada, they try to make the most of the opportunity. There are rumors about Death City, after all, that it's home to an elite school of incredible assassins run by Lord Death Himself. Even if the rumors are exaggerated (which they must be - turning children into weapons is a metaphor, right?), overthrowing such an incredible empire would be a good starting point for global domination.
Unfortunately, the rumors are not exaggerated. Now Brain's left questioning everything he ever knew. Can Pinky and the Brain survive horrifying monsters, powerful Witches, even more powerful traumatized children, and their new owner's twisted experiments long enough to achieve their goal? And will there even be a world left to conquer if they can't work together? Stay tuned to find out!
Updates every time I hit around 1000 words. Does not require a prior knowledge of Soul Eater to read.

Summary
Gibson and Otto get infected by one of the Alchemist’s potions, and have to be quarantined together until they can make an antidote. But it’s hard to focus on your work when feelings start getting involved.
*******************************************************“There was a chemical spill. You should stay back, Captain Shugazoom, your lungs could get hurt.”
“What?” The Captain squinted into the room. “Oh, that. That’s not a chemical spill, that’s just the sex pollen.”
“WHAT?!?!” Otto cried, starting to actually panic now.
Gibson could relate. “We got SEX POLLEN all over our IMPORTANT MEDICAL SUPPLIES???”

This fic broke me and healed me all at once. The character interactions are impeccable, the plot will punch you in the face, and the drama of it all made me laugh, yell, and sometimes cry. Highly recommend

Summary
Dragon AU. In a faraway kingdom, the alchemists of ACME Guild have been tasked by the king to transform common metals into gold to expand the royal treasury and increase the king’s personal wealth, at the expense of the commoners and dragonkind.
Pinkhart is a young dragon who’s been sold to a noblewoman, and though he tries to make the most of his situation after being separated from his mother too early, it’s a lonely existence when he’s a status symbol and nothing more.
But when he meets a dragon from ACME Guild, maybe that will start to change. And maybe he can find a treasure to truly call his own.

Summary
AU. Brain and Snowball are aliens from an abandoned colony on the moon seeking to take over the planet they call Terra. Meanwhile, Pinky's just an Earth mouse enjoying the simple things life's got to offer him. But goals aren't always so clear-cut and things don't always go according to plan.

This is a REALLY GOOD FIC and a very sweet, well-thought-out AU. One of the most engaging interpretations of Pinky and Brain’s characters that I’ve seen in a while, especially since they had to grow up largely separate in this AU. It makes them more complex as individuals, and more engaging when they’re finally together. Highly recommend

Summary
Someone asked me how Bruce Wayne's company is structured and I went a little overboard, so now I'm archiving it Because Reasons. Feel free to use this for your own fics if you are also writing a universe where the Wayne family turned spite and pettiness into a billion-dollar empire.
