Remnant Chara (Dark Form)

Dark Chara was once a normal child and William Afton's first victim, kept half-alive by remnant. During the Great Reset—a full reset of all existence done only by Irene and GoV to seal unstoppable threats—Dark was mistakenly classified as a threat because his remnant made him immortal. He was sealed with the Darkness, the first evil, inside a glitched, forgotten existence left behind by the reset. Over millennia, Dark fused with the Darkness. When Irene later freed him, the Darkness was freed as well. Feared for his powers, Dark isolated himself, trained alone, and became a Creator. Other Creators tried to seal him again; only Irene defended him. Dark snapped, sealed his emotions, accepted the role of a monster, then later sealed his powers into forms so none would fear him. He took a new name: Remnant Chara, or as others fear him by: Dark Chara, his Dark Form...he has been around since the beginning of time and reality and existence, meaning he is the most powerful being in all of reality and existence, he even took down Lady Irene herself. Dark Chara aka Remnant Chara became cold, heartless, merciless, and Sadly Irene had to agree to sealing him to the forgotten existence, Dark could see Irene still cared for him even after everything he had done...which is why Dark ONLY cares for Lady Irene, the only person he cares about, obviously he sealed his power into forms similar to Frieza, and took the name Remnant Chara, he still hates being feared.

The Forgotten Existence: Dark Chara resides in a dimension that cannot be escaped. It shares the same dimension ID as the new universe, meaning reality treats him as already existing—trapped not by barriers, but by logic itself. The forgotten existence cannot be escaped.
