The Pokemon anime has spun over 25 seasons starring Ash Ketchum as its main character. As a farewell of our favourite boy leaving, I'm going to do the unthinkable... rank all the twenty-five seasons of the Pokemon anime so far

BUT WAIT

I'm going to rank it on how interesting the season can get (league battles, evil team arcs not bland old fillers)
I'm going to try and avoid any bias including any favouritism due to nostalgia.
ALSO THERE ARE GOING TO BE A WHOLE LOTTA SPOILERS

Spoiler

so I'm going to use spoiler tags on those which I think will give away important events
