I really want to re-watch Pokemon XY and XYZ but Netflix removed them in April. Also, in my country DisneyNow is not available.
You can use sling or as jay the [sorry but characters in name are confusing] said in my question https://www.watchcartoononline.io/search but you should use a vpn while using there or like I said above sling.
EDIT: Sling is missing all of its Pokemon right now so just use the site above or if you have cable disney's site [you don't need Disney Now]
Edit again: sling is back but you have to type pok otherwise nothing apears.
There is a app called "Pokemon TV" where you can watch any Pokemon anime you want
Hoped I helped :)
Pokemon x and y was recently free on amazon but, unfortunately now cost money. The only place that I know of were it is, is Hulu.
Hope that helped :) :) :)
