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 followed Saitama to the Hero Association's headquarters. Rover and Black Sperm are later entrusted to Butterfly DX, Chain'n'toad, and Forte since they lost a bet with Saitama.
