Summary
A huge list of AU themes that you would most likely find in an Omnilovania or similar compilation. I started the list for fun and decided to post it for others to see and use as a reference. Please don’t post it anywhere else. I do not claim to own any of the characters, AUs, or themes in my list.
Are you looking to make an AU and want to know if a song name or AU name has already been used? Or maybe you need to know which theme goes with which AU for some reason? Well then this is the list for you.

Summary
A comic re-posted from my Tumblr
There's no reason Simon would wake up on the Hail Mary and act rationally after dying in a blood ocean.
So, he doesn't
Good luck to Grace and Rocky

Summary
Ryland Grace is living peacefully on Erid. Peacefully until something (or someone) so monumentally bloody stains the water in his enclosure.
Simon is trying to get by on what he thinks is heaven, until he starts to mutate into something unholy.

Summary
The Blood Eel only knows pain and isolation in its world. Others have come searching for answers, only to learn in the end that death is the only one that matters. But then it meets Simon. As it unmakes him it catches a glimpse of something its never seen before, Happiness. It wants to learn about it, yet Simon doesn't know it. It goes to throw him away, but then he utters a prayer.
Hail Mary, full of Grace
The Blood Eel searches the cosmos and comes across The Hail Mary, occupied by Ryland Grace, and it decides this is what Simon was asking for. So it obliges.
What follows is the story of two lost souls coming together in a cosmic event, learning together to live, to love, to be happy. All while The Blood Eel looks on, insuring it continues to learn, one way or another.

Summary
Maybe what scares him most is how meaningless it feels even to himself. He's fought so fiercely to live, to carve out space for himself with bared teeth and bloodied fists, but the force and drive that had him surviving for so long just isn't anywhere near enough in the face of this complete hopelessness. And so what else is he to do but slump into the corner and see if he'll get lucky enough just to slip gently into oblivion.
And isn't that some sick fucking joke.
Self-indulgent platonic bloodymary fic in which Simon is a teenager that Grace finds cast out into space to die. Someone needs to get that man a child.
