Take a character from any region, and turn them into the Champion, like how Emerald made Wallace the Champion instead of Steven.

Only rule is that the new team has to copy the levels of the previous Champion.

Here I made Volkner the Champion of Sinnoh. Cynthia has decided to step down from the role of Champion, in order to focus fully on her study of mythology. She can be battled in the postgame at Spear Pillar at higher levels instead.
