Lefty

L. ure E. ncapsulate F. use T. ransport E. xtract, also known as Lefty, with The Marionette trapped inside it, is a salvageable, and buyable animatronic in the game. He causes the most damage, and the player cannot get rid of him. It has also been confirmed this is now the body that The Marionette possesses.

Appearance
His upper head looks similar to Toy Freddy's, but his lower jaw is separated and connected with metal rods to the upper part. He has the rosy-red cheeks like the Toys from FNaF 2, and his top hat and bow tie are red. Like the other Rockstar animatronics, he has a star on his grayish chest. He holds his gold microphone in his left hand, fitting the name "Lefty". His left eye is small and black, while his right eye is normal with yellow pupils. His knee pads are also rosy-red. If one looks closely, they can see the Puppet inside of Lefty, which features on a secret death screen.

Overall, it is a black and red version of Rockstar Freddy without his left eye and holds his mic in his left hand as well. He is also a member of the Rockstar Assemble, a band including  'Rockstar' versions of Bonnie, Chica, Foxy, and Freddy.

Ultimate Custom Night
He sits in the closet off of the left hallway. He becomes more and more agitated if the office becomes too noisy or too hot. This state of agitation increases slowly, and will eventually end with Lefty jumpscaring you. Lowering the noise won't reverse the effects, nor will reducing the temperature, and doors won't prevent Lefty from getting to you. The only way to ease his temperament is to switch on the Global Music Box (which soothes all music box animatronics at the expense of extra power being drained)."

=Gameplay= Lefty will hide in the left hall closet deactivated. If there is too much noise and heat, Lefty will become more agitated and active until eventually leaving the closet to hunt the player down. He can't be stopped by the door and lowering the heat and noise can't stop him, But he can be soothed by the Global Music Box (at the cost of a little chunk of power being drained). If the player fails to soothe him in time Lefty will jumpscare the player.
