Ms. Appleby (Psychic-Echo Version)

Ms. Appleby is the principal of Angel Grove High School, and the teacher of many of the original Mighty Morphin Rangers, as well as the teacher of Liam McKenzie. She still teaches at Angel Grove High, but has also picked up the title of Principal after the retirement of the former Principal Kaplan.

Power Rangers Aether
Ms. Appleby makes a breif appereance in Power Rangers Aether. She notices Liam is not doing so well in his classes and seemed rather distracted, and gets frustrated with the fact Liam keeps having to leave class early (due to the increase in the Metalliwisp attacks).

She puts Liam in detention as a result from his actions. While Liam is in detention, She lectures him about how he needs to be more responsible and to focus on his school work. However, the detention is interrupted whenever a Metalliwisp hoard appears in the school, accompanied by a Cybershade monster, which is looking for Ms. Appleby specifically, believing she might have had some information on the Gold Aether Ranger.

In order to protect Ms. Appleby, Liam is forced to reveal his identity to her by transforming in front of her. Ms. Appleby is stunned to learn one of her students is a Power Ranger. After the battle, she speaks with Liam about the situation, telling him that she understands what he was going through, though she is still dissappointed that he is letting his school work suffer because of all of this, and hadn't come to her sooner about all of this.
