Alright so here's the info on the Elite Four, no info about their teams or how they are because of what the "writer" says at the end for this one.
Next time there will be a Profile for the Writer and her team, then I'll more likely then not write a few random entries here and there.
So after obtaining the badges through Combat or Survival, you can go straight up to the Elite Four, present them those shiny medals you worked yourself to the bone to get and battle them…. After waiting for the season of Summer to come that is.
See here the Elite Four doesn't ever allow anyone to battle them until Summer rolls around. Hell if I know why but goddamn I will tell you this… they do NOT go easy on you the more badges you have!
See if you have the standard Eight, they will use their mildly weaker pokemon/Alchemymon to try and make it more fair… more then that and they will use their stronger ones… have every last badge in the region, you get a round of applause… before being destroyed by their strongest team.
As for the champion… well just defeating the champion will NOT make you the champion by default, after all they hold themselves to the same rule as the Elite Four and used their mildly weaker team for those who only got 8 badges.
The only way to become champion is to obtain the whole 16 badges of the region, at minimum 10 of which need to be obtained through combat or survival, defeat the Elite Four's toughest teams with your own… IN A ROW WITH LIMITED HEALING SUPPLIES, then defeat the Champion's toughest team then finally you have to answer one final question.
…. What you expect me to know what the question is? Hell if I know only those who beat the champion at their strongest will know or if they are the Champion.
Besides I'm just a traveler who's out to give advice to newbies or foreigners that want to get by here in Amestris. (Not only that but my team is WAY too rowdy to be even CLOSE to challenging the Elite Four, let alone the champion… besides I've only got three plus an unhatched egg!)
