Iolitemon is the Armor Digivolved form of Impmon through the Digi-Egg of Determination. Its armor is made up of cordierite (iolite), a unique blue gemstone mineral. Its wings consist of flames, and a faint white band of data runs along both of its arms and behind its back. It shares some common characteristics, notably its body structure, with Magnamon. The smiley face that was on Impmon's body before Armor Digivolving is still visible, in slightly modified form, on Iolitemon.
- Spectrum Flare: Absorbs and reflects light in its gemstone armor, and then releases in a burst of multicolored flame.
- Azure Flight: Flies up into the air, leaving a column of blue flame from its wings where it took off.
- Cordier Bracers: Briefly increases its strength, by activating the bracers around its forearms.
