Francis Allen Doyle is a fictional character created by Joss Whedon for the television series Angel. The character was portrayed by Glenn Quinn. Doyle is a seer who receives prophetic visions from The Powers That Be, usually of people in peril. Half-human, half-demon, his demon heritage allows him to manage them without suffering any permanent damage. His half-Brachen demon physiology grants him the ability to shift from normal human to demonic appearance, in which he has heightened sense of smell and superior strength, speed, stamina, and dexterity, the last of which allows him to twist his head around in such a manner as to fake a broken neck. However, Doyle rarely used his Brachen powers, preferring to remain human, thus limiting his usefulness in a fight.

Angel is an American supernatural television series, a spinoff of Buffy the Vampire Slayer. The series was created by Buffy's creator, writer and director Joss Whedon, in collaboration with David Greenwalt. It aired on The WB from October 5, 1999, to May 19, 2004, consisting of five seasons and 110 episodes. Like Buffy, it was produced by Whedon's production company, Mutant Enemy.
