Glory is a fictional character in the television series Buffy the Vampire Slayer portrayed by Clare Kramer. Glory is a god from a hell dimension and was the main antagonist of the fifth season.

Glorificus (also known as "Glory") is a god from a hell dimension in which she ruled alongside two other deities. Her power and dominion were vast and continued to grow stronger and stronger, as did her lust for misery and destruction, and she quickly became the most powerful of the three hell gods. Afraid and fearful that Glorificus would grow too powerful and seize total control of the dimension for herself, the other two allied together and went to war against her. The hell gods barely defeated her, but despite their victory, she was too powerful to destroy, so they banished her into the earthly dimension, where her essence would be imprisoned in a human child named Ben, created solely to "contain" her until he eventually died as a mortal, sealing her.

Glory was too powerful to be completely contained within the human vessel and when Ben reached his 20s, Glory began to gain control over Ben for short periods of time, taking the form of a vain, self-centered human female possessing superhuman strength, speed and invulnerability. Glory's strength was greater than that of any Slayer, vampire or demon on Earth, although her powers were greatly diminished compared with those she had in her true form. Dark magicks prevent humans from learning that Glory and Ben are one and the same; even when she transforms right in front of someone, they instantly forget what they saw. The spell does not affect supernatural creatures like vampires and demons. This becomes a recurring joke in the penultimate episode of Season Five, where Spike finds himself repeatedly having to explain that Ben and Glory are the same person, only for people to either to misunderstand him or to instantly forget. As Ben and Glory's personalities begin to merge more and more (see below), the magic weakens until, in the finale, the whole gang is able to see through it. This human form is Glory's only weakness; if the human vessel containing her is killed, then Glory perishes with him.

Glory's goal is to find the Key, a "mystical energy nexus" which is the only way for her to return to her original dimension. Unfortunately, using the Key will break down the barriers between all dimensions, causing all worlds to bleed into each other and allowing "Hell to reign on Earth". The Key was safe, guarded by an ancient group of monks known as The Order of Dagon. When they discovered "The Beast" (Glory) was searching for the Key they chose to hide it. Using ancient magic they transformed the Key into a human girl and placed her under the protection of the Slayer Buffy, altering the memories of the Slayer and anyone connected to her into believing the girl was Buffy's younger sister Dawn. The Order of Dagon were eventually destroyed by Glory. The last monk of the order was taken prisoner and interrogated by Glory, and later rescued by Buffy. Before the monk died from his wounds he revealed to Glory (under torture) that the Key had been transformed, but not what the Key had become. The monk, after being rescued by Buffy, revealed to Buffy that Dawn was the Key, something she already suspected.
