When is a Ranger Not a Ranger? is an episode in the second season of Mighty Morphin Power Rangers.
Lord Zedd turns Adam's kaleidoscope into the terrible monster Scatterbrain, who uses his brain-scattering powers on Tommy, Billy, and Kimberly to give them amnesia. Rocky, Adam, and Aisha try to undo the process by using prisms, but they too fall victim to Scatterbrain's attack. Who will save the Power Rangers now? Would you believe Bulk and Skull, of all people?
Adam has just finished his school report on his kaleidoscope, which puts Lord Zedd in a bit of a rhyming mood as he eyes the device. While Kimberly, Billy, and Tommy are playing with the kaleidoscope in the park, Z-Putties appear to distract them while Zedd turns the kaleidoscope into the monster Scatterbrain. The Rangers morph but are instantly caught in Scatterbrain's energy beam, erasing their powers and memories.
In the Juice Bar, Bulk and Skull are dressed up in camouflage gear. Their new plan to learn the Power Rangers' true identities is to stake out a spot and hide until they catch one morphing. Nearby, Rocky, Adam, and Aisha are studying a Newton's Cradle, which mesmerizes Bulk and Skull until they pass out, and they take advantage of the opportunity to slip out when Zordon calls.
After being briefed by Zordon, the Rangers meet up in the park. Tommy, Kimberly, and Billy are completely unable to recognize their friends or surroundings, and they have an even harder time believing their so-called friends when they talk to them about the Power Rangers and Lord Zedd. When Goldar arrives to "refresh their memories", the three brain-scattered Rangers cautiously go with Rocky, Adam, and Aisha to the Command Center.
Inside the Center, Tommy, Kimberly, and Billy are in even greater disbelief when Zordon tells them that they are Power Rangers. Adam suggests that deflecting Scatterbrain's beam through prisms might be able to reverse the effect. A plan is set up to lure Scatterbrain outside of the city so as to keep innocent people out of harm's way while Adam goes to Billy's lab to fetch prisms.
Out in the desert, the other four Rangers teleport onto the scene, completely unaware that Bulk and Skull have spotted them. The pair are shocked to learn that the Power Rangers had been (in their minds) playing the role of teenage "dweebs" to throw them off, but follow closely as Scatterbrain arrives. Rocky and Aisha morph to defend their powerless friends as Adam and Billy arrive with prisms, but Adam is brain-scattered before he can do anything. The remaining two Rangers are then brain-scattered while they make one final effort to grab the prisms, which fly off and land near Bulk and Skull as they watch in fear.
With all six Power Rangers no longer able to remember anything, let alone how to morph, Scatterbrain celebrates his victory. However, Bulk and Skull suddenly step out to challenge the monster in a Wild West-styled showdown, complete with randomly-drifting tumbleweed. After a tense standoff, Scatterbrain fires his beam and scatters what few brains Bulk and Skull have, but the beam also hits the prisms they had picked up and bounces it back to the Rangers. Their memories restored, the Rangers thank Bulk and Skull (both of whom having lost their memory of the Rangers' identities) for saving them as Zedd (who is upset that Bulk and Skull, not the rangers, foiled his plan) makes his monster grow, then summon the Thunder Megazord to shatter Scatterbrain.
Back at the Juice Bar, Bulk and Skull are boasting (with some added embellishment) about how they saved the Power Rangers, but no one will believe them. Kimberly and Aisha come by to admit that they believe their story and give the pair some words of encouragement, which cheers them up... or at least until they reject Bulk's offer to take them on a date.

- This episode was one of three episodes released in the Morphin Series. The other two being "Zedd Waves and "Lights, Camera, Action".
- Bulk and Skull's reaction to temporarily discovering the Power Rangers' secret identities is identical to their similar reaction when the Space Power Rangers revealed their identities to all of Angel Grove in Space's "Countdown to Destruction" ("Them?!"), as both episodes have the same writer and director, as well as a four-year gap between them.
- Despite having known Adam and Rocky for some time before the events of "The Ninja Encounter", Aisha describes Kimberly as her best friend.
- This episode contains a couple of references to "Day of the Dumpster". When the memory-wiped Rangers first return to the Command Center, Billy notices Alpha and says, "Whoa! A fully sentient, multi-functional automaton!", repeating his words from their first encounter (this scene even includes a similar view of Billy from Alpha's optic processor). Later, Kimberly uses the same remark of "Would somebody please pick me up and bring me back to Earth?" as she did in the first episode when the situation is explained to her.
- In an earlier script draft, the showdown of Bulk and Skull protecting the Rangers from Scatterbrain was originally going to take place in Angel Grove Park instead of the desert, and the Rangers would've originally stayed unmorphed after regaining their memories. 
- The Zord battle with Scatterbrain is the first time the Thunder Megazord stabs an enemy with the Thunder Saber.
- This episode's description of a kaleidoscope (breaking up light into a million pieces) is inaccurate. Such a description would more accurately fit a prism.
- Adam was the only Ranger to have his memories wiped when unmorphed, but when Scatterbrain's spell was broken by Bulk and Skull, Adam was morphed with the rest of the Power Rangers when they got their memories back.
- After the Rangers regain their memories thanks to Bulk and Skull, Tommy is shown summoning the Tigerzord, but it never arrives.
