Circus Baby

Circus Baby (or just Baby for short, formerly Elizabeth Afton) is the main antagonist/deuteragonist of the 2016 indie horror game Five Nights at Freddy's: Sister Location, and one of the three main antagonists in its 2017 sequel, Freddy Fazbear's Pizzeria Simulator as Scrap Baby, alongside Springtrap and Molten Freddy. However, she made her debut as a cameo in Five Nights at Freddy's World.

Baby was the primary mascot of Circus Baby's Pizza World & Circus Baby's Entertainment and Rental. The soul of Michael Afton's sister, Elizabeth, resides in Circus Baby, and is revealed to possess her in Pizzeria Simulator. She is one of the five animatronics created by William Afton, programmed to kill children through subtle ways. Eliazbeth/Baby can be considered the secondary antagonist of the series as Afton's right-hand minion.
