Buffy

Buffy is an English diminutive form of Buffalo, but in modern use it functions primarily as a pet form of Elizabeth, following the same pattern of creative nickname formations from that name. It gained widespread cultural recognition through the American television series Buffy the Vampire Slayer, which aired from 1997 to 2003, cementing the name's association with a strong female protagonist. Related forms include Buff and the many other diminutives of Elizabeth such as Bess, Betsy, and Betty.
