>Megas are revamped
>Pokemon do not Mega Evolve anymore, the trainer evolves into a Mega Human with Pokemon features
>outside battle, you can customize your base stat and typing, essentially giving us the closest thing to a official create-your-Pokemon
>if you are dual typed, you can only learn moves from those types
>if you are single typed, you can only learn moves from that type and Normal type
>if you are single Normal typed, you can learn moves from Normal type and one chosen typing
>you battle alongside your Pokemon once you Mega Evolve and you play a supporting role with your attacks/effects doing only quarter their usual strength and long lasting effects only working for one turn
>both trainers can Mega Evolve and will be incapacitated for the rest of the battle once KOed, but if a Pokemon or trainer chooses to attack the opposing trainer, they will take extra damage from attacks during that turn
