Pokemon the Series Season 20 Episode 43 When Regions Collide!

As Ash and Pikachu continue their journey through the Alola region, they encounter a strange phenomenon - multiple portals opening up in the sky. Before they can investigate further, they meet up with their Alolan friends, who have also witnessed the portals.

Professor Kukui provides some information on the portals, explaining that they lead to other regions. He also reveals that he has been working on a device that can analyze the portals and give them more information about where they lead.

Intrigued by the possibilities, Ash and his friends decide to explore the portals and see where they lead. They soon find themselves transported to a mysterious land, not like any region they have ever seen before.

As they explore this new world, they encounter several familiar faces from different regions. From Hoenn, they meet May and her Wailord. From Sinnoh, they run into Dawn and her Piplup. And from Kalos, they bump into Serena and her Braixen.

The group soon realizes that they have all been brought to this new world for a reason, and that reason becomes clear when they encounter a powerful Pokemon in the midst of a fierce battle. It's a legendary Pokemon that none of them have ever seen before, and it appears to be protecting this strange land.

The legendary Pokemon seems to be under attack from a group of trainers who are trying to capture it. Ash and his friends quickly jump into action, battling it out with the other trainers to protect the legendary Pokemon.

As the battle rages on, the group begins to learn more about the strange land they have been brought to. They discover that it is a sort of nexus, a place where regions from all over the world converge. They also learn that the legendary Pokemon they are fighting to protect is the guardian of this nexus, and that it must be kept safe in order to maintain balance between the regions.

With this knowledge, Ash and his friends fight harder than ever, determined to keep the legendary Pokemon safe. In the end, they emerge victorious, their new friends from other regions fighting alongside them.

As the battle ends, the group is transported back to Alola. They may have won the battle, but they realize that their adventures are far from over – there are still more regions to explore, more Pokemon to discover, and more legends to uncover.

And so, with renewed enthusiasm and a newfound sense of purpose, Ash and Pikachu continue their journey through the Alola region – and beyond.
