Zack

Zack is one of the main characters of FNaF F.R.I.E.N.D.S., first appearing in Season 2.

Appearance and Personality
Originally an animatronic wearing a dog suit, he is now a barren endoskeleton that comes from the FNaF2 era. Along with this normal form, he also has another form known as Berserker Mode, in which his eyes become pitch black with white pinpricks, and his body shape shifts into an endoskeleton dog, which bears jagged fangs and sharp claws.

Not much about Zack's personality is know, though he does have a knack of protecting his friends at all costs from threats and enemies. There are times where he is happy and tries to cheer his friends, but after seeing multiple friends he knew die, enduring hardships, and living in an all around gloomy world, he has become depressed overtime, at times stranding himself from others. It's also at times of extreme rage or sadness that he transforms into his Berserker Mode, though he now trains himself to learn to control his "inner monster".

History
Making his first appearance in Season 2 Episode 1, he re-activates after an unknown period of time, finding himself covered in rubble. He digs himself out when he realizes that his suit is gone, leaving him as a bare endoskeleton, much to his horror. When he realizes that he is no longer at a Freddy Fazbear's Pizza, he looks around the city, trying to find where the location is. After climbing up to the roofs for a better view of the area, he comes across Donatello, Blake, and Rocket. Not wanting to creep them out with his appearance, he hides behind a roof vent, but one of his wires get stuck, causing him to talk loudly and be spotted by the three. He introduces himself to them, then starts asking about Freddy Fazbear's. When Donatello refuses to answer, Zack decides to just find out for himself, and runs for where it might be, causing Donatello to chase after him.

Zack eventually finds the pizzeria, only to discover a horrific sight: the pizzeria was destroyed, leaving a large crater in its place. Zack is scarred at seeing his home destroyed, and when Donatello and Blake finally explain what happened, Zack becomes enraged and goes off to find and kill any humans who were responsible for the pizzeria's destruction. He eventually finds a party being thrown by a group of Anti-Animatronic members, and sneaks in and executes the members using his sharp claws and teeth. Afterwards, he runs off again in search of more humans, but then he sees a kid with a Freddy doll being bullied by a group of other kids. He goes there and scares off the bullies. This also resulted in the bullied kid to run in fear of Zack's appearance, prompting Zack to leave as well.
