The Old Man is a minor character in Mad Father. There are two distinct old men in the game, but this one has more importance to the game's plot, especially in IF Mode.

The Old Man was taken in to be a servant for the Drevis family, and appeared to enjoy his time there. However, he soon discovered that the family enjoyed taking in weak or homeless people and turning them into dolls afterwards. The Old Man, now realizing who he's working for and fearing for his life, planned to escape in secret and manages to flee as far away as he could. However, Monika Drevis had managed to discern that their servant did not approve of what they were doing and learned of his escape plans. Thus she chased him down and killed him.
