Jonathan "Jon" Possible
Voiced by: Unknown
Mim's closest friend, Jonathan "Jon" Stoppable was a detective, who's every bit as clumsy and scatterbrained as his descendant. He was the only person who believed that Mim was innocent, and he tried desperately, but unsuccessfully, to prove it. Jon was the biggest (and only) fan of the concept of the taco (when it first came out), which parallels Ron's love for the Naco.
