Desetamon is a Mutant Wizard Digimon and a Champion-Class Hybrid Digimon whose name is derived from "deset" (Bulgarian for "ten"). It is the Artificial Human Warrior of Combined Power, a spirit created from the data of the Legendary Warriors. As an artificial Legendary Warrior, its spirit is only compatible with the first person who merges with it. Also, being artificial, Desetamon does not have an Ultimate Human Spirit form.
Like the others, Desetamon resembles a human. It is clad in white-colored armor, mainly basic in construction. On the tops of its arms are the symbols of the original ten Legendary Warriors: Flame, Wind, Ice, Earth, and Wood on its left arm, Light, Thunder, Darkness, Water, and Steel on its right, all of the symbols being their respective colors. Rather than have its symbol in a small area, its whole chest armor is covered in grooves which form its symbol, which looks like the symbols of Fire and Light overlaid on top of each other. Desetamon's helmet resembles that of Susanoomon, only with two differences: 1. The V-shape attachment is absent, and 2. Desetamon has a face with a gray visor instead of just eyes. Its boots have symbols on the toe areas that resemble the Roman Numeral X (Ten).
- Decimator: Fires energy beams from the symbols on its arms all at once, for a total of ten beams.
- Elemental Force: One of the symbols on its arms glows, then an attack of the corresponding element is fired from its hand. Desetamon does not call out this attack's name when it uses it.
