Tails

Miles "Tails" Prower, commonly referred to as Tails, is one of the five threats in Five Nights at Sonic's, who later became a supporting antagonist in Five Nights at Sonic's: Maniac Mania. He was created as one of the four clones to entertain in the first Sonic's Hero Pizza Palace in 2015. However, he turns evil at night due to Dr. Eggman tampering with the cloning machines. As of Five Nights at Sonic's Maniac Mania, he's voiced by Resident (who also voiced Tails Doll, Withered Tails, Nightmare Tails, and Plushtails).

Appearance
Tails takes a similar appearance to Classic Tails, but he wears a eyepatch that covers his right eye and a hook conceals his left hand. During the night, like Sonic, Mario, and Yoshi, his eyes changes to black with glowing, red pupils and his teeth sharpens.

Behavior
In Five Nights at Sonic's 1, Tails starts in his cove (conveniently named Tails' Cove). He'll eventually leave his cove and fly his way down to the left hallway to get to your office. The player needs to close the door to avoid Tails or else if he gets into the office, he'll kill the player. In Five Nights at Sonic's: Maniac Mania, Tails, as usual, starts at Tails' Cove along with Nightmare Tails and Taingle (if two said characters are activated with or without Tails). Just like in the first game, he'll eventually leave to get to the office. However, he'll choose which hallway to go to, so it's heavily advised to close the appropriate door upon hearing Tails' sound cue to keep him away. However, if the player fails to close the appropriate doors, Tails will kill the player.
