Harmony Kendall
Harmony Kendall grew up in Sunnydale, pretty, rich, blonde and not too bright she fit exactly the criteria for being a Cordette and followed Cordelia all through high school until Graduation.  On Graduation Day her life changed when, in the middle of the largest and probably only fight of her young life she got bit by a vampire and turned.

With her new found power and bloodlust, Harmony soon finds someone else to follow, Spike.  But Spike is mean to her and tries to stake her and when he comes crawling back with a chip in his head, hiding from The Initiative she kicks him out.

After reading some empowerment books, she gathers together her own crew, and some nice ornamental unicorns and makes plans to kill Buffy.  When at first she doesn’t succeed, she comes up with another plan, kidnap Dawn to lure Buffy into her trap.  Unfortunately, Buffy kills all her crew and it’s Harmony’s turn to go running to Spike for help, believing that she is Buffy’s arch nemesis.

She remains with Spike until she can take his lust for Buffy no longer and she finally leaves for LA, inviting him to take one last look at her ass.

In LA she soon hooks up with her old friend Cordelia, and when Cordy finds out she is a vampire, she teams up with Angel Investigations and tries to fight on the side of good for a while.  But her evil ways get the better of her, and being a single vampire, with a lust for blood she finds herself working in the typing pool at Wolfram & Hart.  It is here that Wesley finds her and promotes her to Angel’s secretary, sorry Personal Assistant.

Under Angel’s reign at Wolfram & Hart, Harmony is forced to lead a human blood free life, and does so very well until she is set up by a jealous colleague who buts human blood in her flask and a corpse in her bed. Fortunately for Harmony, she manages to find the culprit and smooth things out with her terse boss, keeping her alive for a while longer.  When it comes to the final fight and Harmony has to choose a side, her evil side gets the better of her once again and she betrays Angel but still manages to leave Wolfram & Hart with a letter of recommendation.
