Baldi

For breaking the rules, he locks a student in the classroom, right? But if you break another rule (one that isn't one of Baldi's rules), he'll add it to the basic rules of conduct, limiting your violations. With each mistake, he'll lock you in longer, until the timer reaches an hour.

"A great director because of his incredibly keen hearing! He can tell not only where a sound was created, but who created it!"

Baldi has a strong love for mathematics and rules, so he tries to teach us about them. He is first introduced as a friendly and calm character, although this is likely his usual mood. He greets students warmly and praises them when they answer his questions correctly. He loves mathematics and rules of conduct, and believes that everyone else does too. His love of rules is so strong that when others break them, his personality changes. His friendliness and cheerfulness completely disappear.

Baldi, the Janitor, Mrs. Pomp, Dr. Reflex, and Teacher Derry are the only characters who are school staff.
Generally: friendly, calm, welcoming.
When angered: easily irritated, aggressive.
Punishes for mistakes, hears all sounds, good mechanic.

If Baldi has lost you, he will run around the entire school, checking classrooms and offices.
If you turn on the phone, Baldi will run to turn it off.
Baldi's birthday is June 3rd. He is 29 years old.

Baldi is a humanoid figure with long, skinny fingers, pale skin, red lips, and a bald head with a single red hair. He wears a dark green shirt, dark blue pants, and bare feet with braids. A yellow bow tie adorns his neck.
