Sinister Freddy is one of the main antagonists in Sinister Turmoil.
Sinister Freddy is a large, bipedal animatronic bear.
He bears a main color of brown, while it is broken up by a secondary, lighter brown on his stomach area.
Sinister Freddy is actually an edited creation both from pieces of recovered Fazbear pieces from Fazbear's Fright and anything on hand.
Sinister Freddy was modified from his original form by receiving a sharp set of teeth and a lack of eyes.
However, a majority of his adjustments came from the inside, as a completely new endoskeleton was put inside the suit so movements will be more fluid and quick, causing them to really be able to do harm if necessary.
