Ep 15. The Battle According to Lenora!

In Pokemon season 14 episode 15, titled "The Battle According to Lenora!", Ash and his friends arrive in Nacrene City, excited to challenge the town's Gym Leader for their next badge. The Gym Leader in question is Lenora, a serious and intellectual woman who also happens to be the town's museum curator.

After arriving at the Nacrene City Gym, Ash and co. learn that Lenora's Gym focuses on Normal-type Pokemon, a versatile group that can learn a variety of moves. The group heads into Lenora's Gym, ready to challenge her and her Normal-type Pokemon.

In the meantime, Team Rocket is also in the area, hoping to steal some rare artifacts from the museum. However, their plans are quickly foiled by Lenora and her trusty Watchog, who manages to stop their attempt at stealing a valuable artifact.

As Ash and co. begin their battle with Lenora, it quickly becomes apparent that this Gym Leader is not to be underestimated. Her Normal-type Pokemon are powerful and well-trained, making the battle much more challenging than the group initially thought.

Nevertheless, Ash and his Pokemon are determined to come out on top. Throughout the battle, they use their training and quick thinking to stay ahead of Lenora's moves and ultimately emerge victorious.

As the episode draws to a close, Lenora congratulates Ash on his impressive skills and awards him with the Insect Badge, his third badge on the road to becoming a Pokemon Master. With another successful Gym battle behind them, Ash and his friends continue their journey across the Unova region, eager to face whatever challenges may come their way.
