My current concept for Team Destiny is simple enough. There will be four facilities, each one consisting of an Executive and three Commanders. Each facility functions much like an Elite Four, in that a challenger must first defeat the three Commanders (in any order), then defeat the Executive, using the same team with the same moves. However, they can change everything for the next facility.
An issue I have run into is the number of Executives. While we have 12 Commanders, perfect for pairing with 4 Executives, there so happens to be that #5 spot.
"But Davis, why don't you just have the President be a final boss for after someone has defeated the four facilities?"
That's a good question, me.
Because then what does the challenger get to do with their team for that?
Free game? Our final boss will go down fast and hard.
