Five Nights at Freddy's: Security Breach takes place in a massive entertainment complex known as Freddy Fazbear's Mega Pizzaplex, which has animatronic mascots, Glamrock Freddy, Glamrock Chica, Montgomery Gator, and Roxanne Wolf. As the animatronics perform for an audience at the complex, Freddy suddenly suffers a malfunction and breaks down on stage, ending the performance.

As a result of the malfunction and his fear of Vanessa, Freddy disobeys her orders and instead guides you to the lobby to help you escape, only for the complex to lock up for the night and trap you inside until they reopen in the morning. As you got separated from Freddy you had to go into the underground section, only for a broken down version of Glamrock Chica to ambush you!

”Hehehehehe!! Oh look at you, you cutie child!! C-Come to Chica!!!”

This Chica was ruined, she wasn’t the original version chasing you down inside the Freddy’s Megaplex on the top floor, this was an alpha prototype model of Chica… so that’s why she didn’t recognise you.
