5. Anne Steele
Anne Steele (born Joan Appleby and formerly known as Sister Sunshine, Chantarelle and Lily Houston) is one of the few characters to have appeared in both Buffy the Vampire Slayer and Angel, having appeared in five episodes in total. She was a social worker and the director of the East Hills Teen Center in Los Angeles. Having formerly been a runaway teenager herself, her life was saved on two occasions by Buffy Summers (for example when she nearly died at the hands of Spike when she was a vampire worshipper) and she was also later aided by Angel and Charles Gunn (for example when her centre came under attack from zombie police officers). Despite facing many hardships growing up, Anne maintained an optimistic outlook on life. She was very cute and, initially, very naive, but turned in to a very responsible woman.
