Ash is the main character people. He is naturally going to be seen a lot in the anime series. I think he should have evolved pikachu by now, I mean its at a high enough level that its learn probabaly all of its best attacks. Don't be in such a hurry to get rid of ash. Pokemon has been on for 9 seasons and counting. One day, Pokemon is going to have to start back from the drawing board and the story will be completely different. Ash Ketchum may not even exist. But that is kind of why Chronicles came out, too focus more on other trainers. And I have the feeling that Ash will one day, maybe not capture, but befreind a legendary pokemon and use it in a battle, so don't be in a hurry. And honestly, if they were to get rid of Ash, the anime series would go straight down the hill. Ash has been on too long to just take him off. Ash is there to stay for a few more seasons at least, and if you don't like it, stop watching the anime. For that reason, if its a natural catastrophy, get a copyright thing to make your own series of pokemon where Ash never existed.
IF YOU GOT A PROBLEM WITH ASH, TOUGH, GET A LIFE!!!
