Fic ideas requested!

Hello everyone,

Lately I have been making preperations for a series of short stories called 'dark & twisted endings'. Basically, every part is a one-shot story where the ending of a story gets changed to give a dark ending to it, with mostly the focus on villainesses winning or heroine's turning evil. I have some ideas in mind, but not nearly enough and I am all out on inspiration. So if you happen to have an idea, let me know! Also, whilst you could suggest very popular stories like sailor moon, I think there has been made plenty and I wanted to make this a series on more lesser known stories.

You can feel free to rummage through my idea pit and take whatever and tune it to your own desires.  I do have a few general ideas in there as well...  As for series not really touched that have those bad end possibilities, off the top of my head that's

Fate/Stay Night UBW with Caster. Saber, & Rin...
Queen's  Blade has a few moments with Melona, Menace, & Airi, not counting stuff covered in Vanquished Queens, Rebellion and Grimoire...  
Najica and Aika always have the "things going wrong and the villainess getting the upper hand" moments...  
FFFXIII-2 could have one in the recruitment fight for Jihl...
Kid Icarus: Uprising could have something between Palutena, Amazon Pandora, and Medusa but it would probably require a original scenario
Project X Zone has tons of crossover potential, and of course there is my Lady Riamissanne mind controlling kisses
Dragon's Crown has potential with the Vampiresses, or the girls in the gallery like the beast controlling Dark Elf, mud golems, or the in game doppelgangers
Senran Kagura could have Katsuragi getting corrupted/charmed/drugged by Haruka, or one of the girls could employ a mind controlling Secret Art



And of course you can look through the sightings we have and pick one to give a bad ending to since there are loads of potential there.

Thank you very much! That idea box is very helpful indeed!

Sadly I don't know most of these shows, but that gives me something to watch I guess. That Jihl character from FF13 looks gorgeous though :O
