A Deltamon was controlled by the Digimon Kaiser. In a plot to humiliate Daisuke he had several Bakemon disguise themselves as the other Chosen Children so Daisuke would think he had captured them. The Digimon Kaiser called forth Deltamon and said he would feed them to him but that because Deltamon only had three heads he could choose which one he wanted to save. Daisuke said to take him instead so the Digimon Kaiser agreed and sent Deltamon at Daisuke, but then the real Chosen Children arrived and saved him. Deltamon battled Daisuke's Fladramon but was unable to stop Fladramon from breaking the Evil Ring controlling him.
Appears in Area 02 and Area 03 as a wild enemy encounter.
