This is a really hard one! I have kids who I consider the ‘man kids’ for each region, but a lot of the main kids in each region don’t interact a whole ton with each other, save for a few exceptions, so choosing just one to represent the whole bunch would be tough. Another big part of this is that, since Ash doesn’t exist in this world, there’s no one protagonist who’s kid would follow in his footsteps. But, if I had to choose just one, it would probably (at least at this point in time) be Draco. He is one of the few fankids who has definitely traveled to all the different regions and he has a lot of development along the way. He would be quite the antihero though, considering his…… charming personality, but I think he’d probably be the most interesting to follow as the protagonist, since he’d be the most likely to meet all the other kids. A second choice, and one a bit more heroic than Draco would probably be Amaryllis, since she’s Red’s daughter and is somewhat of a foil to Draco. Perhaps Rylla would be the protagonist and Draco would be the antagonist/anti-hero 

¯_(ツ)_/¯ .
