Dr. James Timothy Possible
Voiced by: Gary Cole
Kim's father is an astrophysicist, a rocket scientist. His full name was revealed in "So the Drama" by Big Daddy Brotherson. His name (Jim Possible), like his daughter's, is a play on the word "Impossible". It was revealed in season 4 that he was a graduate of the Middleton Institute of Science and Technology (MIST) and that he enjoyed writing Captain Constellation fanfics. In the crossover episode "Rufus", Kim revealed that James was best friends with the Senator of Hawaii when they were in high school. He doesn't like when Kim is with boys. He often said "as long as you are not with boys, I am ok" and yet he is fine with Ron.
