Played by Adrian Edmondson, Vyvyan is an orange-haired, mohican punk rocker and medical student. He is extremely violent and regularly attacks Neil and Rick with pieces of wood, cricket bats and other large objects. He never hurts Mike, whom he respects. He hates Rick more than he does Neil, taking every chance to insult and attack him. For example, when Rick, Mike and Neil meet his mother at a bar in the episode "Boring", he calls both Neil and Mike his friends, but not Rick, whom he calls "a complete bastard." Although Rick and Vyvyan hate each other, this makes them all but inseparable; the two spend more time together than apart, or with the other housemates.
