OC I made. They're originally from the Red Rabbit dimension, but got yeeted out into the multiverse because of the dimension Being Weird (eldritch axolotl thing is bored af) and crash-landed in the LAES dimension. Day found them and was like, "Oh cool now I don't need to build a replacement of my ex-boyfriend."
Calling this the Skyfall AU. More lore under the cut.
Sky used to be an entertainment robot, but started doing some bounty-hunting on the side (one of the few ways robots could get money). Trapeze artist by day, bounty hunter by night. They got yeeted into LAES on one of these hunts. (eldritch axolotl thing likes to play with its toys)
Day put the USB in Sky's head when she was unconscious, allowing him to coerce her to do evil or whatever. The cast assume its a hair-clip or something.
Remember when the crew used a drone to spy on Day? Someone pointed out that it looked like he was talking to someone in the shed. In this AU, he was talking to Sky, bringing her up to speed on what she needs to do.
