Rusty's out of jail and on the move - with Peanut Butter (his Perfect Bidoof) by his side! And, uh, destroying everything in his wake. Yep, Rusty has (essentially) a god under his control, so this should end well.
Rusty's made it...surprisingly far! He's escaped prison, defeated the Elite Four, and has a Perfect Bidoof doing his bidding. All that's left is to catch all the legendary Pokemon! There's no way Rusty will screw this up! No way at all!
