If you pick Patamon or Gomamon, you can fill in every in-training/rookie except Lucemon

You can actually fill out all the babies and childs except Lucemon. Gomamon and Patamon are both from Poyomon, I think it will be easier to start with Patamon since it's base personality is Enlightened and it lets you devolve into Poyomon faster. Grinding personalities is probably going to be the slowest/random part of the game

Tokomon goes to Patamon/Coronamon/Terriermon/Armadillomon/Lucemon
Bukamon goes to Kamemon/Crabmon/Gomamon/Gizamon/Syakomon

So you can only have 1 from those 10 in the demo, you can have multiples of the others if you want
