Buffy the Vampire Slayer went through a lot of changes during its seven season run. With an incredible amount of plot twists and excellent character development, looking back it's clear the show was always introducing new ways to throw its audiences off and create a strong, multi-layered narrative.
The following 15 episodes are not necessarily the show's best (though many of them are), but they're certainly the most invaluable of the bunch. Whether introducing viewers to characters who would soon become fan favourites, throwing up a mean twist or killing off a major character with little to no warning, all of these episodes helped shape the very fabric of Buffy and its overarching stories.
For this list, we're going to be focussed on the show's most pivotal episodes, starting with its first season and ending with its last, charting the show's most iconic moments and the developments that helped shape the series and its spin-off, Angel.
With that in mind, here are the 15 most important, game-changing episodes in Buffy the Vampire Slayer.
