I don't understand the naming scheme. Besides my own personal complaint that if you're going to make a Digimon game in English, you should use the English names (which like I said is a personal complaint, and I'm not going to fault people who disagree) there seems to be no logic to it.
There's ones like
DemiMeramon (English name) instead of PetiMeramon or PetiteMeramon
Chrysalimon (English name) instead of Kurisarimon
Gobli- and SnowGoblimon (English names) instead of Goburi- and SnowGoburimon
But then there's others like
PicoDevimon instead of DemiDevimon (English name)
Chibimon instead of DemiVeemon (English name)
Growmon instead of Growlmon (English name)
Ganimon instead of Crabmon (English name)
And those are just the ones I've noticed. Also, unrelated, I absolutely love Kurisarimon's movement animation.
