Overgrown Rover (育ちすぎたポチ, Sodachisugita Pochi) or Rover for short is a Dragon-level Mysterious Being and a member of the Monster Association. Its role is to guard the Monster Association headquarters to prevent intrusions.
Rover is a very large black six-eyed creature. He has fangs and resembles a monstrous-like dog. Although appearing very large in size at first, Rover was speculated by Black Sperm to have been weakened since it has gotten smaller in size after the battle between the Hero Association, the Monster Association, and Garou.
Rover behaves like a dog. It listens to any order given to it, even if it's from the enemy. Despite being one of the most durable and powerful monsters within the series, it has followed simple commands from the likes of Bang and Saitama to sit.
Human Monster SagaEdit
Monster Association ArcEdit
Overgrown Rover encounters Garou and Busaiku when the two are trying to escape to the Monster Association headquarters. Garou and Rover begin to fight, Garou ends up telling Rover to sit and punches Rover into the ground where they were fighting, leading them to fall into the headquarter's basement. Rover later encounters Saitama. Saitama tells Rover to sit and punches Rover into submission. Afterwards, Rover encounters Fubuki, Genos, Bang, and Bomb, who were trying to enter into the headquarters. Rover starts fighting against them and during the battle none of the members of the group are able to injure Rover, even after using their combined attacks. Out of annoyance, Bang rhetorically asks why Rover couldn't simply be quiet and sit down. Rover, remembering being forced into submission by Garou and Saitama after they gave the same command, obediently sat and stopped the fighting. For the remainder of the invasion, Rover's enormous size began to reduce drastically until it became not bigger than an average dog.
Psychic Sisters ArcEdit
After the destruction of the Monster Association, Rover rejoins Black Sperm and together they persuaded Saitama to take them to the Hero Association's headquarters in A-City. Rover and Black Sperm are later entrusted to Butterfly DX, Chain'n'toad, and Forte since they lost a bet with Saitama.
