Pico

In FNF, Pico was added to the game in collaboration with Tom Fulp.
Some of Pico's character traits:
Aggressive and murderous, Pico rarely shows fear and fights mercilessly against anyone who stands in his way.
Paranoid - doesn't trust others too much and is always armed.
Recklessness - During the destruction of the school, Pico immediately takes action despite the danger.
Unstable - In the unreleased sequel Pico's School, Pico has an unstable personality, usually inserting insults or sarcastic comments into his responses.
At the same time, Pico has proven himself a reliable friend and ally to those he truly trusts. For example, he twice betrayed Dear Daddy to spare and even save the boy when he was ordered to kill him.
Pico is also shown to have incurable schizophrenia, which is why he never goes anywhere without a weapon.
