Mr. Ka-Boom is Mrs. Ka-Boom’s husband and Katie Ka-Boom and Tinker Ka-Boom’s father. He usualy causes some situations where Katie gets mad (Katie Ka-Boom: Call Waiting) and tries to calm her down. 

He has brown hair and wears a blue sweater over a white collared shirt, black shoes and brown pants. He’s voiced by Rob Paulsen, most famous on the show for his role as Yakko. Based on the appearance on mannerisms of Mr. Ka-Boom, it’s strongly suggested he was modeled after actor James Stewart, in particular his role as George Bailey from It's a Wonderful Life.
