Personality:
Mike is the lone survivor of the Child murder, and been traumatized through the last of his childhood of watching his friends getting brutally murdered in front of his eyes. in the start Mike was struggling with his long grief and nightmares from his earlier job as Nightguard and trying staying alive from Freddy, Bonnie, Chica and Foxy there was out for blood.
 
a year later, a new Freddy Fazbear Pizza opened and to his huge surprise. none of the animatronics are bad anymore, in fact, they are friendly. at first he thought they weren't the same, but it didn't take him long realizing that Freddy and friends are the same animatronics that tried killing him (they just didn't know) and they were in fact sentience. to Mike's greater surprise, it didn't take him long befriending them and slowly getting over his grief from his friends. Mike's once great fear to the animatronics has since completely disappeared and now doing as much as he can to help his robotic friends with the restaurant and that comes in sign with taking the parent role for the new addition of animatronics: the Toys. Mike don't mind doing it, even though the Toys can be quite the handful as they have no idea the difference between good and bad, not to mention they all either hate or fear other humans.
later on and with some help from the Marionette, Mike realize that his death friends and his new friends; the animatronics are the same. it came as a huge surprise, but he never felt so happy being reunited with his friends.

Note: Mike has a huge role, so whoever chose to be Mike's voice can't be busy.
