Mario - the second antagonist of the game, acts the same as Bonnie from the first game.For his role, he is supposed to be the comedian and lead singer of the group. Like the other characters, he's not the real Sonic, but it's a clone. He becomes active from the third night, but can try to attack Knuckles when the office runs out of power starting from the first night. Appears in the office, preferring to walk in from the right door. He is based on the Classic Sonic design and acts just like Freddy Fazbear from the first game, wearing a black top hat and bowtie but has a little difference: first, he appear when the door lights are turned on and if someone else is on the camera, second, he can go into Pirate Cove. After the fourth night, he stops calling, because of presumable death after Sonic attacks him. Throughout the game he gives Knuckles advices to help the latter survive. Luigi - carries out the role as Phone Guy.Knuckles the Echidna - the main character of the game who got a job in a new pizzeria where he has seven nights to survive.Management and all locations of the game are also similar to the original game. The game's office is identical to original from FNaF. Once again, the place was shut down and the clones stayed in, rotting for 2 years. He really didn't care about the clone's attitude. After that he went off hiding, but not before working to get the place shut down, he was triggered cuz he didn't had much money. And finishes his week but is fired due to his attitude, his odor, but most importantly, for not watching the Master Emerald. And so, Knuckles, who were playing on the actual game, became the new nightguard. Luigi was the first nightguard of the restaurant, working for five days and doing phone calls for other guards, but then on his 5th night, the Sonic clone attacks him because the power ran out all of the sudden. The Tails clone started to slowly be broken for only a few days, and his cove was shutted down. They waited for the process but Eggman who found about that and snucked in the place decides to ruin Sonic's name and the business, by messing with the machines, which makes the clones evil at night. The clones were planned to be made, when the day came they all went in their respective machines, with accessories on them to do like Origin Sonic, i suppose. Mario & Yoshi who ware Modern's friends suggested to join Classic Sonic, Classic Tails did too. Classic Sonic who was with Modern Sonic agreed to be cloned another time at promises the new cloning machines would work better.
But in his condition, he was now called "Golden Sonic", having all his cloning material melting on his face, with the bloody teeth from the bite. An obscure company built an new restaurant called "Sonic's Hero Pizza Palace", the place where Origin Sonic was took.
