Jimmy is Bea's longtime husband and Betty's maternal grandfather. He was a scientist who was studying the musicality of space rocks. He was lost years earlier while trying to discover sounds on a distant planet, but was found on The No-L 9, a collection of singing planets in "The No-L 9". Betty manages to find him, but not before protecting the planets from Maximus. Since then, he has settled in the Moose Jaw countryside with Bea. He later makes a reappearance in "Wedding Crashers", when Bea and Jimmy decide to organize a "second wedding", attended by both Betty's parents and the entire Galactic Guardian organization. Beatrixo's evil sister Auntie Matter is jealous of her sister's relationship with Jimmy, to the point she kidnaps him in "Wedding Crashers" and tries to grant Jimmy superpowers like hers so she can marry him. However Jimmy is saved by Bea with a little help from their granddaughter.
