"Interesting enough, Freddy himself doesn't come off stage very often. I heard he becomes a lot more active in the dark though, so, hey, I guess that's one more reason not to run out of power, right?"
- Phone Guy, describing the behavior of Freddy during Night 2
Freddy Fazbear (often referred to as Freddy) is the main antagonist of Five Nights at Freddy's. He is an animatronic who stalks the pizzeria of Freddy Fazbear's Pizza, and seemingly roams around the hallways.
Freddy Fazbear is a teddy-like animatronic who is able to move around the pizzeria freely. Throughout the nights in the original Five Nights at Freddy's game, he is noticeably the most unpredictable animatronic, and the only way for the player to notice Freddy's movement is through the glaring white eyes through the monitor.
On stage, Freddy is a bear, with a black tophat, and dons a bowtie. He is also seemingly holding a microphone on his right hand, implying that he plays as the lead singer in the band. His ears are attached onto the costume, and as a result, they're able to move in a forward and backward position.
Before the attack
Previously, Freddy Fazbear was the lead singer in the band, while Bonnie plays the guitar, and Chica plays as the backup singer. Together, they play their songs and entertain the children while they're housed inside Freddy Fazbear's Pizzeria.
