New Digimon
As with Digimon World DS, Dawn and Dusk introduce several new Digimon to the franchise. Chicchimon is a new Bird based Fresh/In-Training Digimon. Grimmon, ChaosGrimmon, and EXO-Grimmon also make their first appearances in the game as the main enemy. Grimmon seems to have a connection with Chronomon Destroyer Mode, a boss from the first game.
Dawn and Dusk also complete the Digivolution lines of the Digimon from Digimon Data Squad, with the likes of ShineGreymon and MirageGaogamon, after having been left out in the first game. DotShineGreymon and DotMirageGaogamon make their debut, with DotAgumon and DotFalcomon returning from the first game and also includes DNA Evolution to obtain stronger Digimon. It is possible to have certain digimon that were bosses in previous games. For example Kimeramon and SkullGreymon.
