Mary

Mary is the wife of Mark the Mailman, first appearing in Mark & Mary Marry. William Missionima was their best man, also attempting to help a Logdotzip-referenced redstone heart.

She reappears in Swapper, where she talks to William after he and Mark the Mailman switch bodies. She says she thought about getting a roof. "Mark" shortly tends to the kids, Mike and Martha Mailman. Seconds later, Teddy calls Mark the Mailman and William and says he created a reverse system to the device, enabling Mark and William to be put in their original bodies.

She makes a third appearance in Garyzilla, in which she hires her good-gunner lawyer to snipe Gary after he enlarges into a beast. The lawyer is soon killed as a reference to Jurassic Park.
