Angel was an American comedy-horror series created by Joss Whedon and David Greenwalt for The WB, as a spin-off of Buffy the Vampire Slayer.
After realising that he can never be with his lover, the vampire slayer Buffy, Angel (David Boreanaz) flees Sunnydale and runs to Los Angeles. As the only vampire in the world cursed with a soul, Angel seeks redemption for the brutal killings he has committed in his 200+ years on the earth. In LA he meets Doyle (Glenn Quinn), a charismatic and noble demon whose prophetic visions show him people in need of rescuing. Angel and Doyle, along with former Sunndydale alpha female Cordelia Chase (Charisma Carpenter), open up a detective agency, hoping to help the helpless and earn redemption for Angel.
Over the course of the series, Angel battles many dangerous enemies, many involved with demonic law firm Wolfram and Hart, and makes loyal friends including Wesley (Alexis Denisof), a rogue demon hunter; Gunn, a former gangster turned battler of evil (J August Richards) and Fred, a geeky girl from the sticks (Amy Acker).
- At the end of the third season of Buffy the Vampire Slayer, the characters of Angel and Cordelia were spun off into Angel. There were multiple crossover storylines between the two series, and two other Buffy regulars eventually became regulars on Angel: Wesley Wyndham-Price and Spike (James Marsters).
- Wolfram & Hart's clients include Yoyodyne and Weyland-Yutani. Yoyodyne was referenced in The John Larroquette Show and Star Trek: The Next Generation. Weyland-Yutani made the weapons used at the Battle of Serenity in Firefly and a Weyland-Yutani ship from the film Aliens could also be seen in some wreckage in the Red Dwarf episode "Psirens".
