If Pokémon had a new trainer every season it would be a much better series

[Formerly Black Trash]

Don't know why they don't
X and y was good
And sun and moon looks like it will be too
But tired of the same formula
Ash loses the league and goes on to the next one and gives up his pokemon

 

[Days of Future Piff]

Co-sign. If they gave Red's storyline a beginning, middle, and and end and then transitioned to the story of Gold...

Then characters from previous arcs make cameos later on...

I'm pretty sure there's a manga that did this...

 

[The Prince of All Saiyans]

Don't know why they don't
X and y was good
And sun and moon looks like it will be too
But tired of the same formula
Ash loses the league and goes on to the next one and gives up his pokemon

just lettin' em go like "well see ya"

 

[Green negs and spam]

Co-sign. If they gave Red's storyline a beginning, middle, and and end and then transitioned to the story of Gold...

Then characters from previous arcs make cameos later on...

I'm pretty sure there's a manga that did this...

Just imagine that epic battle between Red and Gold at the end of Gold's run.

I think the reason is because Pikachu (not Ash) is too popular in Japan. There's no way to keep Pikachu while dropping/transitioning away from Ash.
