They've never been shown, in Japan or the west.
They were meant to be on right after last year's Tsunami; they got postponed, but they're planned to be shown eventually.
dude..........u still watching poke-e-mon? Seriously?!!
Why not? It's just a show like everything else. People have their likes and dislikes so 'nuff stereotyping. Watching mature-themed shows doesn't automatically make the viewer a mature person.
