Ink

Ink is a Papyrus who deletes universes once they reach a high enough point, likely because he hates them because he doesn't have his own. Little is known about him, but it is likely that he only wears a pencil and paints to look less evil, so he can trick others. He is apparently the secret villain of the Swapverse Comic (currently uncreated). This likely indicates that he was the one who broke the deal, likely by trying to delete X-Swap, causing X-River Person and his creations to become evil. He often fights Reboot.
