Five nights with Brief.

Brief - He has raspberry-colored hair (which is shoulder-length) and dark raspberry-colored eyes. He wears a raspberry-colored jacket with a light raspberry-colored bow tie and dark raspberry-colored pants. He's strange, can be quite cruel, vindictive, doesn't like being touched (though he can sometimes allow it), and enjoys watching people suffer. He also has a friend, Yoshka. He attacks from both sides. And he hates Knife. (That's why he can sometimes strangle or beat Knife.)
Yoshka has purple hair (his is also shoulder-length) and lilac eyes. He wears a purple shirt and purple pants. He's a very kind, positive, sweet, and sympathetic guy. (Only to the animatronics!) Unlike Kratkiy, he cares about people. (And some people mistake him for a girl, although he's actually a guy!) He's a friend of Kratkiy's, and he can appear in your office and attack you.
Knife - He has gray hair and brown eyes. He wears a white T-shirt with a hoodie over it, and gray pants. He's withdrawn, pessimistic, unkind, whiny, and rude. He can tease everyone, and he can sometimes call everyone names. He also has an enemy, Kurasan . He often teases Kratkiy, calling him "Robin" or "Raspberry." (It's safe to say he hates Kratkiy, too.) He also has a friend, Light Bulb. He attacks from the right door.
Light Bulb - She has blue hair and slightly dark blue eyes. She wears a blue dress. She's kind, cheerful, positive, and doesn't do rude things. (This applies to the animatronics!) But she's easily upset, and she's Knife's girlfriend. She attacks from the left door.
Kurasan - He has brown hair and dark brown eyes. He wears a brown T-shirt and blue jeans, and is the shortest of all the animatronics. He's usually a rude, ill-mannered, and cruel guy. (Well, he can very rarely be caring and gentle.) He attacks from the ventilation vents and has an enemy, Knife.
