 Being one of the largest meerkats in the group earned him the description of a "bruiser", ready and willing to lead the charge against any Whiskers rivals, or rival males trying to get too close to any of the Whiskers females.After Flower's death in the third series, Zaphod continued to perform the duties as the group's dominant male and would chase off any roving males trying to reach new dominant female Rocket Dog.As meerkats will not mate with first generation relatives, he eventually left the group and became a roving male.
