Mac is a natural born mom. Being the most level-headed of the Glamrocks, she tends to be the voice of reason when it comes to physical safety. When she’s around the kids at the Pizzaplex, she always manages to insert a safety lesson in almost every conversation she has. She’s very loving toward the kids, with most of them coming to her when they get lost or hurt, because Mac will always treat kids and grownups alike with maternal love and kindness. When Gregory is looking for parts from the other animatronics to salvage for Freddy, he takes Mac’s auditory processing enhancers. This causes Mac to go completely deaf, and as a result get extremely worried about the lost child in the Pizzaplex, constantly calling out for him to come to her so she can protect him, keep him safe, etc. Even when infected with the “Vanny Virus”, her internal programming to care for the children still comes out in her speech, even though it might not in her tone.

Bonnie Bowl?

Mackenzie operates at her bowling alley in the Mega Pizzaplex, Lotor Lanes. In canon, it’s said that Bonnie Bowl was in dire need of a re-theme after Bonnie was decommissioned; Enter Mac! While Monty took his place on stage, Mackenzie took over his attraction as the newest addition to the glamrock team. Mac has no knowledge of Bonnie, so when children ask about him she responds with something along the lines of, “Who? Is that your friend?” Because of the nature of her arrival, the others in the Glamrock team are hesitant to warm up to her at first, but soon come around.

Ruin

As of the events of Ruin, Mackenzie has been damaged almost beyond repair. When Gregory was taking parts from the other animatronics to upgrade Freddy, he took her auditory enhancers. This was done while she was chasing him through a vent above Lotor Lanes, Gregory quickly ripped her ears out and kicked her back, pushing her into a fan above the establishment and mangling her. This action removed both her hands, and the bottom half of the shell on her tail. The entire shell of Mac’s left arm was destroyed, showing just the upper arm of her endoskeleton left. The casing on Mac’s back and right foot were also destroyed, again, showing her endoskeleton. At every point of damage, Mackenzie has exposed wires that are live and flickering. In Ruin, Mackenzie is by far the least damaged of her peers. This is because she hid, not allowing herself to be seen, in an attempt to not be hurt any further. Mackenzie became feral in a sense, crawling in the vents and hissing at the light.
