Full list of appearances
Mr. Caplan is the principal of the Angel Grove High School. He alternated between being well-meaning and strict, but in some episodes he seemed more as a secondary antagonist. He is notable for frequently putting Bulk and Skull in detention, and once falsely did the same to the Power Rangers, keeping them from performing their duties. He occasionally had some animosity towards Jason, as shown in "Teamwork" and "Food Fight".
- Though "Food Fight" is the first episode to air that has Mr. Caplan, "Teamwork" predates the episode as it's the episode where the Rangers get their Power Weapons.
