This article is about a/an episode in Mighty Morphin Power Rangers.

A Chimp in Charge is the one hundred and fortieth episode of Mighty Morphin Power Rangers. The 18th Zeo Serial Short aired before a later airing of the episode.


Katherine and Aisha help teach a chimpanzee, Kelly, to communicate with sign language for a school assignment. However, Rita Repulsa and Lord Zedd turn the ape into the Sinister Simian monster to lure the Power Rangers out to fight her. Now, the Rangers have to find a way to defeat the ape monster without harming her and return Kelly back to normal.

  • When working on the antidote, Billy told Zordon he was still trying to find a way to deliver it. However, the projectile that he would later use was already in front of him.
  • When Billy talks about hitting the right spot, the shot is mirror-flipped (as evidenced by the control panels on the Shogun Zord's cockpit being on the opposite walls to normal).
  • Billy states that the projectile has to hit close to Kelly's heart, as this is "where memories are kept". However, any scientist, especially one as intelligent as Billy, would know the heart is not responsible for the storing of memories.
  • When Kelly returned to normal size, she was wearing none of the items the fruit stand owner had given her.
  • Zedd laughed at Rita telling her this was what happened when she tried to take over Earth alone, however, he'd had an active role in the plan.
  • At the beginning of the episode, Kat is seen in the classroom with the other Rangers getting the last assignment of the school year, despite it being said in A Ranger Catastrophe, Part II that Kat would start school in the fall. It also brings into question whether the Rangers are on summer break or not, as they are shown being in and out of school.


  • Final appearance of the White, Pink, Yellow, and Blue Ninja Rangers, as well as the last use of the Ninja Ranger forms.
  • This is the third and final episode where Kat calls to use the Ninja Ranger Forms. Curiously, she gives the call even though Tommy is present.
  • Third time Kimberly (who had been replaced by Kat as the Pink Ranger since "A Different Shade of Pink") doesn't appear.
  • Last appearance of Ms. Appleby in Mighty Morphin Power Rangers. She makes her first and only Power Rangers Zeo appearance in "A Brief Mystery of Time", though archive footage of her is used in "There's No Business Like Snow Business", Part 1.
  • Apart from the "powering up" shots, the Zord fight is entirely American-produced footage. In Kakuranger, the monster was defeated by the Battle Borgs.
  • Finster references King Kong.
  • Ironically, Bulk and Skull later come to understand a whole lot more about chimpanzees when they are each transformed into one during the first half of Power Rangers Turbo.
  • Katherine takes a hit from one of Rita's and Zedd's monsters as did previous Rangers and onward so.
  • First and only episode where one of the Rangers confronted Finster.
  • Bulk makes a joke about Kelly being Tommy's twin brother  This foreshadows Tommy's encounter with his actual brother, David Trueheart, in Power Rangers Zeo's "Challenges".
  • A chimpanzee's natural diet does not include bananas.  Bananas are native to southeastern Asia.  Chimps normally eat termites, other invertebrates, small vertebrates, flowers, leaves, seeds, and especially the fruit of the Strychnos spinosa tree (which, like chimps, is native to tropical Africa).
