The Digivolution system of this game is the same as the one for the v-pet and pendulum Digivices.
Botamon
The First Digimon You will get no matter What.whether you train it or not he will always digivolve to Koromon.
Koromon
This is the digimon that gives you the hardest training point almost Ever! Usually for some reason you will likely end up with Betaman some people like that one but most would like an Agumon but most are really unsure.
Betamon
This is the most common digivolution form of Koromon.
Agumon
The best form that you can from a koromon.It can be recieved by not allowing a koromon to have to call you 3 times.
Numemon
The worst digimon you could ever possibly get. Its a rookie with powers of a weak champion it digivolves from rookie digimon of the Botamon family that are weakly trained or sometimes even overly trained.
