I mean come on. I wanna see Porygon-Z!
Yep. They deserve another appearance, even though they seizure-ified japanese kids. Seriously, they didn't screw up bad enough to never be in there again!
IT WAS PIKACHU'S FAULT!!!!!
Yeah, it is rather ridiculous. It was actually Pikachu's move that caused it, and later they altered the episode to fix the issue anyway.
