Mom (voiced by Kath Soucie) is Dexter's and Dee Dee's red-haired mother; a woman who is afraid of germs and has trouble being around the rest of the family without her rubber gloves. She is rarely seen without her gloves, and, should she happen to lose them, starts to go insane (as in she starts having nightmarish hallucinations, featuring over sized bugs and germs) in an episode - Pslightly Psycho" to be exact - when they have gone missing from her nightstand.
Although a stereotype housewife, a few episodes imply most of Dexter's personality comes from her, including her perfectionist streaks, red hair, intelligence, and her penchant for dramatics. She speaks in a kind of Minnesotan accent. Even though Dextor's parents was smart, Dexter's mom has been shown to be nowhere near as moronic as her husband. In fact sometimes she has been shown to be very smart. It is revealed in a flashback episode that she used to be a Valley Girl type in the 1980s, which may also be the basis for her accent. In Chess Mom it is revealed that she used to be a cheerleader in high school. She is always seen walking on her tiptoes and her feet make a very dainty, clicking sound whenever she walks around which explains how Dee Dee inherited the squishy sound her feet make when she walks around. On that note, it is revealed in one episode that Dee Dee inherited snowball fighting skills from Mom. Her real name has never been revealed, and her husband only refers to her as "honey", "dear", etc. When she was a baby, she was a pacifier sucking addict as a baby and always whined.
Dexters mother has also shown to be able to fight very well. She beat up another mom, rescued Dexter from aliens, and helped Dexter save Japan.
- She sometimes visits Dexter with the cyberchase fighters always trying to keep Dexter safe when she visits
