Mike is the grumpy but caring husband of Linda. Like his sons, he's ginger. Mike doesn't seem to mind the Monster culture as much as his wife, Linda. For most of the film he is perfectly fine with the monster lifestyle and does his best to respect it. However, he does seem to not like Dracula that much at first. He's annoyed at how Dracula calls his grandson, Dennis, Denisovich. He also thinks that Dennis should move to Santa Cruz with him and the rest of the family where he'd be more safe and accepted since Dennis shows more signs of being a human rather than vampire.
