Dark Cosmos Sans is the offspring of Undernight Sans and Outertale Sans. He lives in Suetale to keep GaryStu Sans company and because he has nowhere else to go.

Appearance Edit

He wears a navy blue robe with yellow stars at the bottom, a cape with varying shades of purple, white mittens, and brown boots. One of his eyes has a galaxy pattern in the background, with a black shaped star, and his other eye is just purple with a rainbow heart. He blushes black, and his tounge is static.

Backstory Edit

One night, Undernight Sans and Outertale Sans got drunk. They did the soul fuse and fell asleep. A few years later, a Sans was spotted roaming the galaxy, clogging black holes and tending to the stars. Of course, Science Sans and the other Sanses researching were curious. To lure the Sans in, they set up a decoy star robot and sent it out to where the Sans was presumed to be next. The Sans saw it, and it looked like it wouldn't shine bright enough. He grabbed onto it, and the "star" started to zoom towards where the other Sanses were researching. The robot crashed right outside of the observatory the next night and right next to the star was a very defeated looking Sans. He got up, and since he never saw a planet like that before, he started to explore. Science Sans was originally going to bring him inside, but one of the other Sanses persuaded him to let Specimen X wander around a bit. After a while, the Sans started following the other Sanses back to the observatory room. When they got there, they looked surprised to see that Specimen X was following them. They lead him to a testing room and performed some tests. Really, just letting him follow them to the Testing Room was a test in itself. They ran tests about his species, his gender, his sexuality, and finally, his SOUL. When they found out that it was composed of space vacuum, light and Undernight Sans' and Outertale Sans' SOULS, they were shocked. How didn't they find him sooner? Eventually, though, they let him rest. They all had a long day, and the next day was going to be even longer.
