Dextor's parents are the parents of Dextor and are smarter versions of Dexter's parents (Mom and Dad). They believe to know what is best for a child like Dextor, however despite the strict education and diet they give to their son, they are rather cold and unfeeling and display none of the warmth and love that Dexter's parents are known for.
- In the credits, they are simply referred to as Science Mom and Science Dad.
- They are the complete opposites of Dexter's parents.
- However, unlike Dexter's mom, Dextor's mom wears glasses.
