Digimon World DS

So is classic Agumon in this game? I see his icon is.

Nope, just his color swaps, black shadow and snowy white, considering that his "default" color in this game splits off into GeoGreymon this time around, in which in-game is not really hard to get, and I know ChronomonHM's one of the harder ones to obtain too, since you get to defeat him TWICE, then bring his in-training form back to his origional form, which has some REALLY ballsy requirements to obtain, second only to Omnimon and/or GallantmonCM.
