Agatha and Amelia try to take their mother's power and run the Academy themselves, however Mildred and the Miss Cackle from the present talk them out of it. It turns out Agatha is the eldest (by 13 minutes), not Ada as they believed, meaning that Agatha was supposed to inherit the Academy. Their mother told Ada that she lied about which twin was older as she wanted Ada to have the school, because Agatha would never run it according to the proper values.

Agatha ends up getting expelled and sent to Wormwood's Academy (where wicked witches are sent) while Ada becomes head girl. They apparently attempted to run the school together, but it was a disaster.

Trivia

  • Despite being evil, she's proven to be pretty intelligent at times, like in her first appearance, when she ordered Coldstone and Bindweed to take out Hardbroom: the most powerful witch in the academy. In her second appearance, she tried to eliminate Mildred as an enemy before her takeover, knowing that the girl would pose as a treat to her plans.
  • In all of her TV and film appears Agatha is played by the same actress, as her twin sister Amelia Cackle.
  • The Worst Witch is often compared to Harry Potter because both series are fantasy, and centered on boarding schools, they were both written by British authors, and the character's personalities are similar too.
