Pokemon the Series Season 15 Episode 34 An Epic Defense Force!

Ash and his friends are on their way to Nimbasa City to compete in the Unova League, but they come across a group of people who are preparing to defend a nearby village from a group of villains called the Team Rocket Trio. The group consists of a reporter named Mannes, a ranger named Joel, and a scientist named Freddy, who have formed a defense force to protect the village from the Trio's latest scheme.

The Trio has created a giant balloon that will release a powerful electromagnetic wave that will paralyze all of the villagers' Pokémon, leaving them defenseless. After learning about the defense force's plan, Ash and his friends decide to help out and join the force.

As they prepare for the Trio's attack, Mannes sends out a call to all Trainers in the nearby area to come and help defend the village. Many Trainers, including several characters that Ash and his friends have met on their journey, respond to the call and arrive to help.

The group sets their plan into motion and successfully prevents the balloon from releasing its electromagnetic wave. However, the Trio manages to escape and vows to continue their evil plans.

Ash and his friends continue on their journey to Nimbasa City, but they are grateful to have been able to help defend the village and its Pokémon. They vow to do whatever they can to help protect the Pokémon and people of the Unova region from any threats that may come their way.
