OK K.O.! Let's Be Heroes is turning out to be one of Cartoon Network's most popular shows among their newest lineup. With an awesome cast of characters like Enid and Rad, there's tons of superheroes to spot in K.O.'s town. However, we have yet to see or hear much about K.O.'s father... Is it possible that he is still lurking in the shadows? Will we ever see him on the show EVER?!
