Page "Illyria (Angel)" Paragraph 29

; Angel: Illyria was a regular towards the end of the Angels fifth season in 2004, first appearing in " A Hole in the World ," replacing Fred.

Technically, since she is played by the same actress as Fred, it could be said that she was credited as a regular from her first appearance, but the first instance of the opening sequence showing Amy Acker specifically as Illyria and not Fred is in " Underneath ".

Illyria appears in 8 episodes in total.
