Played by Adrian Edmondson, Vyvyan is a psychotic punk metal medical student. He has orange-dyed & spiked hair and four metal stars seemingly embedded into his forehead. In the episode "Interesting", he drinks a pint of blue liquid which makes his hair fall out and the number 666 is visible on the side of his head. He is extremely violent and regularly attacks Neil and Rick with pieces of wood, cricket bats and other large objects. He never harms Mike, whom he respects, and often addresses as "Michael". He despises Rick more than he does Neil - 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 refers to as "a complete bastard." Ironically, this antagonistic relationship between Rick and Vyvyan makes them virtually inseparable, as the two spend by far more time together than with the other housemates. Unlike Neil and Rick, Vyvyan appears to come from a working-class background (something Rick incorrectly believes himself to have).
