Mr. Stoppable

All info provided http://kimpossible.wikia.com/wiki/Mr._Stoppable

Mr. Stoppable (voiced by Elliott Gould) is the father of Ron Stoppable. He is an actuary which allows him to work anywhere. Ron has mentioned that his dad has allergies to nearly every kind of animal hair, which led to Ron buying Rufus when he was young. Mr. Stoppable is Jewish, as it was confirmed in "Bad Boy".

It appears that he also happens to be a mathematical genius, and once assisted Team Possible on a mission to defeat the Mathter. In several episodes ("Ron the Man", "Odds Man In" and "Mathter and Fervent"), Mr. Stoppable appears to want to guide Ron with good fatherly advice and be considered his hero. Ron appears to be closer to his father than his mother ("Mathter and Fervent"), as he appears to be somewhat laid-back (like Ron himself is) and more accepting of who Ron is than his wife.

While he does seem to genuinely care about his son and what Ron thinks of him, both he and his wife do not seem to acknowledge or consider their son's thoughts or feelings on matters as being important. Often they make major changes to his and their lives without telling him, leaving him clueless until it's already happened, such as adopting Hana and moving his stuff to the attic, not telling him that they were moving to Norway until the day they moved, and telling him he was going to Camp Wannaweep only when the bus had come to pick him up. When asked by Ron why they didn't tell him, Mr Stoppable says 'This is our way of telling you'.

Ron finally gets back at them for doing this when they walk in to find Hana running on the ceiling. When they find out that Ron knew this, his father asks why he didn't tell him. Ron smugly replies, "This is my way of telling you".

His first name remains unknown. Some fans expect Mr. Stoppable's first name is "Ronald". This wasn't addressed in the series. He is allergic to any kind of fur, as seen in "Rappin' Drakken" and A Sitch in Time''.
