Ink!Sans is an out!code character who does not belong to any specific alternative universe (AU) of Undertale. He exists out of them but can interact with them. Ink cannot interact with the habitants of the AUs, because otherwise he could alter with the story or direction, he can only interact with the out!codes. Ink!Sans supports the artists to keep contributing to the fandom and generally embodies an artistic aesthetic that even follows him in his combat abilities.
