Ink demon

The Ink Demon is a nearly invincible, ink-based entity capable of manipulating ink, teleporting through walls, and instantly regenerating his form. He alters reality around him, kills other ink creatures on contact, and can transform into the monstrous Beast Bendy when threatened. With implied infinite power, fourth-wall awareness, and possible planetary-level influence tied to the Cycle, he's a terrifying force beyond comprehension.
