Idea I has~! It's based off an old plot which never really came to fruition.
The PokeSpe kids were just getting together for a reunion, right? Just a plain old lunch at a local cafe. Nothing really amazing has happened since Red, Green, Blue, Yellow and Silver became unpetrified. However, adventure seems to dog these thirteen kids like a shadow. In a flash of light, about two thirds of the kids disappear, leaving a random selection of kids to stay and wonder what has happened. One of the thirds have been transported to a place where things seem to work differently- the contests, for example. Some of them are being mistaken for other people, like Red being called Ash on multiple occasions. The last third is also in a different place. Everything seems so stoic and boring, and once the shock has worn off they quickly go insane with monotony. Again, a few of them have been mistaken for other people, like Ruby being called Brendan. What has happened? How will they get back? Let it all unfold...
I love cross-canon stories, though there isn't that many. So, how's this?
