The Ninja Encounter

The Ninja Encounter is a three-part episode in the second season of Mighty Morphin' Power Rangers.

Synopsis
Three teens from nearby Stone Canyon High School come to Angel Grove for a ninja tournament and find themselves targeted for recruitment by Lord Zedd, learning the Power Rangers' secret identities and becoming friends with them in the process.

Plot
Tommy, Kimberly, and Billy meet Rocky, Adam, and Aisha and their teacher Hank Anderson after rescuing his baby son, Jacob from a runaway stroller. Later that week, the rangers watched the newcomers win a ninja tournament against a team of undefeated, yet arrogant champions, who caused the stroller incident.

Lord Zedd was interested in recruiting the champions because of their evil qualities, but when he learned that the other side won the tournament, he was forced to recruit them instead. He sent Goldar and a platoon of putties to kidnap the three kids and Mr. Anderson. Tommy, Kimberly, and Billy tried to save them, but were unsuccessful.

Afterwards, the rangers had to balance rescuing the four civilians with saving Angel Grove from two monsters. They managed to defeat the monsters and save the hostages at the very last second, but as Billy was wrestling with Zedd's evil snake, he was severely weakened. Tommy and Kimberly had to take Billy's helmet off for him to avoid suffocating. However, unbeknownst to them, Rocky, Adam, and Aisha were watching on from the entrance to the cave, and inadvertently learned the identities of the Power Rangers.

Rocky, Adam and Aisha are taken to the Command Center. Having found them to be of good character and due to their bravery, Zordon decides to trust the three with the secret of the Rangers' identities. Rocky, Adam, and Aisha agree, taking a vow to never reveal what they've learned, and they reunite with their new friends..

Errors

 * At the very beginning of Part 1, Jason & Trini's stand-in's faces can be seen briefly from the side and front respectively.
 * In Part 2, before Tommy kicks the Hatchasaurus, he asks where he went, even though he was facing the monster before asking the question.
 * In Part 3, Kimberly calls Billy and Tommy by name in front of Rocky, Adam, and Aisha before Billy is unmasked, though she may not have been aware they were behind her.
 * At some points during the battle between the Thunder Megazord and Hatchasaurus in Part 2, footage of the Dino Megazord can be seen, as it was reused from Season 1. In one shot, the full Megazord is clearly visible for several seconds; near the end of the battle, the Megazord's hand is shown grasping the original Power Sword, before cutting to a shot of the Thunder Megazord and Thunder Saber.
 * In Part 2, Zordon told Tommy to destroy Cardiotron, but that was never shown.
