S15E41 Iris and the Rogue Dragonite!

In Undella Town, a sudden blackout prompts the gang to investigate, leading them to suspect a rampaging Dragonite might be the cause. Iris soon finds the creature and feels it isn't malevolent at all. However, things take a turn when she gets cornered in a room with the Dragonite, along with Ash's Oshawott and Dawn's Piplup, creating a tense situation for them all.
