Skullgreymon itself might be something you consider early on as it has 150 Attack and SpA. Ignoring the Skullgreymon bit (which is Fire/Dark), it goes Fire to Fire/Steel to Fire/Ice (as Omegamon) and has a solid movepool. So you want Greymon, but alas, this is the first of a very long line of 'attack > def' evolutions and as with most of them it's fucking dumb because Agumon has 70 base Attack and 60 base Defense. but then will turn into Metalgreymon either way, and while Skull was better, Greymon gets you shit like Megahorn.
This line is also designed to make you hate yourself because Agumon will turn into either Greymon or SKULLGREYMON. If you know what Agumon is but no other Digimon, yes, this becomes Agumon. Koromon is also a Baby II and is Normal/Fire.
