Amanda was sent to Buffy for beating up another student who was picking on her.
Amy appears again in Seasons Two and Three as a Sunnydale High School student.
Aware that Amy has inherited magical power through her mother and has become a practicing witch (after seeing her use magic to deceive a teacher into thinking she has submitted her homework when in fact she has not), Xander Harris asks her to cast a spell to make Cordelia fall in love with him in the episode "Bewitched, Bothered and Bewildered" with humorous and potentially disastrous results.
The show's popularity caused it to spawn a multitude of Expanded Universe tie-in material such as comic books, novels, and video games, as well as a spin-off program entitled Angel.
In 2007, four years after the television series' seventh and final season, Buffy the Vampire Slayer was officially continued in the comic book Season Eight.
Buffy, Giles, and the Scooby Gang combine forces to defeat her.
When a spell Catherine/Amy cast against the Slayer backfires, Amy's spirit is restored to her own body and Catherine's spirit is trapped in a cheerleading trophy she had won in the 1970s (shown in Sunnydale High's trophy case).
She is not seen again in the TV series after this but no mention is ever made of her death, and it is presumed she most likely survived the destruction of Sunnydale by leaving beforehand along with the rest of the town's population.
The character has appeared in the comic book series Buffy the Vampire Slayer Season Eight and Season Ten.
Due to various scheduling issues none of the six planned characters were able to appear in the episode, their roles either being assigned to other characters or otherwise written out.
Had the character of Amy appeared it would have marked her fifth appearance in the series, and the first time that the character would have appeared in more than one episode per season.
Amy repays Willow by introducing her to the warlock Rack and abetting Rack in addicting Willow to dark magic.
