Biff is a human colleague of Colin Robinson. He appears in What We Do in the Shadows (TV series).
When emotional vampire Evie Russell began working at their office, she kept pretending to fall over and told her colleagues tragic stories to make them feel sorry for her. This took away potential feeding for Colin. One day, both psychic vampires tried to feed off Biff at the same time. They both followed and cornered Biff to a toilet cubicle, Evie told him sad anecdotes while Colin tried to engage in dull conversation. So much of Biff's energy was consumed that he fell into a coma and was taken away by paramedics. The incident caused the two vampires to engage in a psychic battle, but then call a truce and start dating instead.
