Misty and Ash continue to wander the Viridian Forest when they spot a Weedle. As Ash battles it, he's distracted by a boy dressed as a samurai and calling himself (naturally) Samurai. Samurai challenges Ash to a battle, and Ash gets the advantage when his Metapod defends itself against Samurai's Pinsir. Samurai sends out his own Metapod—and a standoff begins.

A swarm of Beedrill interrupts the battle. Ash flees, but leaves his Metapod behind. The Beedrill grab Metapod and take it back to their hive. As Ash sneaks toward the hive to save Metapod, Jessie, James, and Meowth shows up to cause trouble. Ash is able to duck the angry Beedrill, and they instead focus their wrath on Team Rocket.

Metapod is mad at Ash for being abandoned. Has Ash learned his lesson about leaving his friends behind? Will Metapod evolve again? And will Samurai and Ash ever resume their battle?
