Unknown

In a timeline that no longer exists, there was once a version of Undertale where everything followed a familiar path... until it didn't.

She doesn't use a name anymore. Most just call her "Unknown."

Once, she was the Sans of her world-lazy smile, quiet jokes, and a sharp awareness of timelines. But her universe wasn't reset... it was erased. Torn apart by Error Sans, leaving nothing behind but fragments and echoes.

Unknown survived-but not whole.

Now she drifts between broken AUs, a glitch in existence itself. Her humor is quieter, colder. She remembers things she shouldn't, feels timelines that aren't hers, and carries the weight of a world that no one else can mourn.

She doesn't fight to save timelines anymore.

She watches.

Because when you've already lost everything... what's left to be afraid of?
