I've gone to Pokemon.com, and I've heard rumors about them...
Where are they?
you could go to http://dubhappy.com/ i go here its free and always work.every Pokemon episode is on this site
They're here: http://www.pokemon.com/us/tv-episodes/watch/
Altough I reccomend this site as it has all the episodes/movies etc as opposed to only some:
You can try going to http://animefreak.tv/ to find some episdoes. Most are in english.
