Page under construction and in no way shape or form to be used as an index.

This is a page that lists ideas for Fanfiction, mainly ideas from people who don't have the confidence, the talent, the skills, the passion, or willingness to put in the effort to just sit down and write it themselves. Not everyone is meant to write, but a good idea is still a good idea whether it is put into practice or not.

Please put what media-work the fanfic ideas are based on. If you have any specific details about the story, characters, or the medium, please include it into the description. Please refrain yourself from making edits to another person's idea, but if you have anything to add to a preexisting story idea, please indent the following example under the preexisting example. See Example Indentation in Trope Lists for context.

The L1MBO is a spaceship designed to find orphaned children from across the galaxy and care for them until they are deemed fit to rejoin intergalactic society.

While the angel milk formula has not stunted her growth like the humans and has since grown into her teens, the glitch in Jude's programming has led to her being cared for as a baby by the Judies since babyhood and never developed past it mentally.
