One of these three:
a. there's no evil team; a rival class or school fills its place. Your rival also comes from that rival class or school.
b. the evil team is a group of cartoonishly conservative group of Pokémaniac/Nerd Pokémon trainers that thinks things changed too much in the past 20+ years and try to sabotage whatever the new gimmick that replaces gyms is.
c. the evil team is another bunch of clowns that want to reshape the world using whatever the magic power of the third uber legendary has. Instead of technology, they'll either be the complete opposite or use actual magic.
