Ooohhh, I get it now. Tank was the hero from the Explorers games. I'm kinda worried about what happened to his partner, though... unless the Yamask WAS his partner.
Well, I'm stupid! In the time it took me to write the first half of that last comment, I forgot that Tank said on this page he and Namira saved the world, and that the Yamask's name was Namira. I r totally smrt!
So tank used to be human. I thought the different appearances of pokemon were result of natural selection and mutation in a apocalyptic pokemon only world.
Oooh how interesting. I like this take on the story. So the Kabuki mask must mean Namira was a vulpix/ninetales.
