Null is a mysterious corrupted character in the Baldi's Basics series, who later becomes a major antagonist in Baldi's Basics Classic Remastered.

Null appears to be an almost invisible entity. He appears to be nothing more than a T-posing set of photo-realistic clothes, hair, eyebrows, and eyes. He wears blue jeans and a red T-shirt.

Null does fourth wall breaks, feeling obviously aware of why or how he is in the game. He claims that he is corrupted for classified reasons.
