Stories that should be on my favorites but aren't, because they're not on this site:
Dungeon Keeper Ami (Sailor Moon x Dungeon Keeper) - forums.sufficientvelocity.com/threads/dungeon-keeper-ami-sailor-moon-dungeon-keeper-story-only-thread.30066/
Sailor Mercury, magical girl and warrior for love and justice, accidentally ends up in another world wielding inherently evil powers. She tries to do good, and kicks ass with SCIENCE!, but it seems like every time she overcomes a problem she finds a bigger problem...
Manager (Worm) - forums.spacebattles.com/threads/manager-worm-story-thread-iv.301602/
Taylor Hebert is Slenderman, bogeyman of capes. This is by the same guy who does "A Drop of Poison".
A Cloudy Path (Worm x Supreme Commander) - forums.spacebattles.com/threads/a-cloudy-path-worm-supreme-commander-thread-four.310497/
Worm setting, Taylor Hebert is a Tinker with more room for escalation than most. Life craps on her, and she fights back. She's very very effective at fighting back, but somehow her problems keep growing...
Mother of Learning (original) - www.fictionpress.com/s/2961893/1/Mother-of-Learning
Zorian was a 15yo misanthropic student mage in a fantasy setting, before he got caught in a "Groundhog's Day"-style time loop. Mystery / Grinding / Adventure. Keep your eyes open when reading the first few chapters - EVERY detail mentioned, no matter how small, will become relevant later. This is by the same guy who does "Scorpion's Disciple". Book 1 & 2 are finished, book 3 is in-progress.
That Gnawing Worm, Cancer (Worm AU) - forums.spacebattles.com/threads/that-gnawing-worm-cancer-worm-au.391395/
Taylor Hebert uses her powers to secretly give Emma migraines and Madison bad hair. Sophia she doesn't touch though, not yet - as a Ward, there's too high a chance that someone would figure things out if she did something to Sophia. Taylor doesn't worry about whether it's right to use her powers in petty ways - Taylor just doesn't give a fuck. Why would she care about that kind of thing after being diagnosed with terminal brain cancer? This is by the same guy who does "People Lie".
Heromaker's Legacy (Worm AU) - forums.sufficientvelocity.com/threads/heromakers-legacy-worm-au-original.7589/
Worm started to happen, but early in the timeline a major Outside Context Power sympathetic to humanity wandered into the the setting, was a bit confused by the whole Entity/Cycle/Shard thing (which are equally confused by him), made a few small but important improvements to the setting, got distracted, and left. Later Taylor Hebert triggers with her canon power... and then finds bits of the infrastructure left by the OCP and slowly begins to understand it. Soon she's nilbog!Taylor, and her understand is still growing... A word of warning though: this story can feel like slow motion after a while - there's functionally half a dozen copies of Taylor's personality now, and they all get their own perspective on a regular basis, so it can take over a hundred pages for a single day to pass. Also, this is a VERY overpowered Taylor - not as Sue-ish as stories like Acceleration, but in terms of raw power or at least potential power it's far beyond any other Wormfic that doesn't have a ROB.
