Here’s Cimon and Narcyz, the Charged AU versions of Dream and Nightmare! From what I hear, Dream and Nightmare weren’t initially Sans in concept; rather, they were... balls of light, or something? As a result, Cimon and Narcyz aren’t exactly like their classic counterparts; They were created indirectly due to Sparky having horrid night-terrors. It’s a sort of parallel in a sense; and as the two of them stemmed from this little conundrum, they look and are physically a little young. They may hold the appearance of a young teen or a pre-teen (So please don’t go and make lewd stuff with these two, that’d be really messed up to do).
They come to know my Ink (Canon) and Error (Windows) after creation in the white void, allowing for the four of them to work together on protecting the Charged AUs.
Fun little thing about Narcyz and his tentacles: They come directly from the coat tail! Annnd if you’re wondering about if the two of them get along? Yes, they do. their time frame events are quite different from Dream and Nightmare’s, and so their dynamic is different as a result. They wouldn’t be able to physically fight eachother anyway; the White and Black Charges would cancel eachother out, forcing them to come up with alternative solutions.
