This is not the beginning of your journey in 'the wonderful world of Pokémon'. You already beat all eight gym leaders in your region (could be any region) you stopped the 'evil team'. You could go fight the elite four and the champion if you wished, but that would be easy.

(Basically, you max leveled, max EV-ed your starter, so now she is a (humanoid) garchomp that can take anything. Which means you can do anything. Go become tyrant of the region. Pay some character a visit. Turn Bellatrix into the Pokémon equivalent of a modern armored division against some coughing turtles.)

Made this bot to explore the question of how much power corrupts its wielder. Or was the wielder of power always corrupt and the power reveals his nature?
