Pokemon Ultimate Journeys: The Series Part 2. As the title of the series suggests, this is Ash and Pikachu’s final journey, and they’re the two main protagonists.
Both characters have contributed significantly to the Pokémon franchise over a long period of time. It’s strange to believe that the series could continue without them, but the Pokémon Corporation has made that choice.
When this season ends, a new series with a whole new cast
the protagonist will debut.
Pokemon Ultimate Journeys: Series Part 2 Plot

Ash has developed into such a talented character that the allure of early adventures and facing the toughest trainers as a novice has been lost. Ash did not need to prove anything to anyone because he was already a champion.
The adventure is over, so this final competition serves more as a victory lap than the rest. While it may be difficult to say goodbye to such endearing characters, to those who share their journey with them, they will all the time represent the core of the Pokemon universe.
Final Explanation of Pokemon Ultimate Journeys: The Series Part 2

Let’s look at the final understanding from part 2.
This second installment of the final episode of Pokémon Journeys is dedicated to the conflict between masters.
Cynthia, the Sinnoh region Pokémon champion, takes part. Cynthia fights a water-type Pokémon.
While some of the Pokémon are of a different type, such as the Dragon-type, most are water-based. These masters virtually all the time use dragon types because of how effective they’re in battle.
Iris, on the other hand, is the current regional Pokémon champion in Unova. Iris had a wide understanding of Cynthia’s methods and plans because she had been her trainee.
This battle has the potential to be legendary since Iris also uses Dragon-type Pokémon. It is in a sense. As Cynthian and Iris begin their fight, it is clear from their very first Pokémon that they are not messing around. The real deal is this.
Iris chose Excadrill, while Cynthia chose Gastrodon. Excadrill looked at a disadvantage in this fight when Gastrodon performed a rain dance to create rain. Excadrill’s DNA contains a Ground-type gene.
When it seems impossible, Excadrill surprises and defeats Gastrodon. However, Cynthia’s following Pokémon summons will not be very easy to defeat. He decides on Milotic, and the Pokémon soon defeats the battered Excadrill.
With their first Pokémon, Cynthian, and Iris made it clear from the start of their encounter that they weren’t messing around. This is the real thing, friends.
Iris chose Excadrill, while Cynthia chose Gastrodon. When Gastrodon uses the rain dance to create rain, Excadrill appears to be at a disadvantage in this fight. Excadrill has Ground-type DNA.
Excadrill defeats Gastrodon even although it is impossible to do so, leading to an unforeseen victory. But Cynthia’s next Pokemon will not be very easy to beat. Milotic was his Pokémon of choice, and quickly overcame the worn out Excadrill.
