What channel is Pokemon Sunday in the US?

There isn't a show called "Pokémon Sunday" in the US.

There are many different Pokémon shows and programming, though. Are you perhaps thinking of:

* Pokémon the Series (currently airing on Cartoon Network): This is the main anime series.

* Pokémon Journeys: The Series (also on Cartoon Network): This is the latest season.

* Pokémon's YouTube Channel: They upload new episodes and other content there.
