#1 - Transmission Impossible
Power Rangers - Season 5 - Episode 5
Arriving from the Planet Inquiris to deliver a message of great importance to Dimitria, the alien Visceron is brought down by Divatox, and when he refuses to talk, she meddles with his mind and turns him against the Turbo Rangers. Meanwhile, Tanya's KAGV radio show is targeted both by Divatox (a detonator is placed on the transmitter tower) and the Bulk & Skull Chimps (they hope to get noticed as humans by getting on the air!)
#2 - The Power Stealer
Power Rangers - Season 2 - Episode 8
The Ranger teens head yet another clean-up drive in Angel Grove Park. Lord Zedd sends down the Octophantom monster, who siphons off most of Tommy's Green Ranger powers. He also captures a couple of the Rangers, leaving only Billy & Jason to free their friends and defeat Octophantom via his only weakness: his vanity.
#3 - Rock-a-Bye Power Rangers
Power Rangers - Season 4 - Episode 30
After two weeks of constant Cog attacks by the Machine Empire, the Zeo Rangers are run ragged, exhausted by both their superhero duties and those of their normal life. Having gotten them to a weakened, sleep-deprived state, King Mondo sends down the Somnibot monster, whose lullaby spell-singing manages to exploit this achilles heel. Can the Gold Ranger wake them in time? Meanwhile, Bulk & Skull are entrusted to guard a safe containing a valuable item for one whole day, unaware that a cat burgler has his eye on it.
