Ash and May are characters in the Pokémon anime series. Ash meets May in the Sinnoh region in the 541st episode.
I think its when ash is don at the Sinnoh region and goes back to pallet
Depends what region you want to know what Pokemon he has. In Sinnoh he has Pikachu, Gliscor, Monferno, Grotle, Buizle, and Staraptor
Ash will go to the Isshu region. He takes pikachu along and will travel with Iris and Dento.
The Isshu Region.
They start to talk about it in episode 746. There Ash re meets the Sinnoh region champion and help out a hurt Pokemon (that Team rocket hurt) and help it out. Than they ride a water plane to get to the east part of Unova. There the champion tells Ash someone that he knows is there. If you want to wait and see DO NOT look below It's Dawn (the girl Ash traveled with in the Sinnoh region!)

Paul is a purple haired rival of Ash in the Sinnoh Region. He treats his Pokemon poorly, and lets go of Pokemon that he thinks are useless. He is stronger than Ash, considering that all of the battles Ash has been in with Paul have ended with Ash losing or them getting a tie. Paul has a brother named Reggie, who is much nicer, and has earned every badge their is to earn in every region except for the badge of the Pyramid in Sinnoh. Paul has also faced Sinnoh's champion, Cynthia, but lost. She gave him advice, but it is hard to tell yet if it has had any affect on him.
Lucario and the Mystery of Mew.
Ash entered the Sinnoh region with Pikachu and Aipom, Team Rocket arrived and took Pikachu away, but their hot air balloon went down and Pikachu flew into the middle of a forest, which is where Dawn met Pikachu and tried to catch him. Ash was determined to find Pikachu , and he found a Starly and caught it so it could search from the sky. So practically, Starly was his first in Sinnoh region.

yes he goes to a new region called the issue region.
