My story is
From the Proffesor you take your starter pokemon he has 3 children (2 boys and a girl), he has no connection with them. He sends you to connect with them and also collect badges. Meanwhile you know of a bad group whose aim is to creeate a world where they are supreme and everyone are their slaves (name you decide). You connect with 1 boy and 1 girl who has become scientist in different cities. You also come to know that the 3rd one is also a scientist but u didnt find him. people inform he has been not seen there for over 3 months. The bad group has also arrived since 3 months. Is there a connection.
In the last after winning the league you came to know that the last scientist was the head of the bad group but he already fled to another world with the help of arceus. peace again florished in the region.
