Alice McCoy is an 11 years old girl with blond hair, and blue eyes who dresses in the gothic lolita fashion style.

Alice is the granddaughter of Professor Rob McCoy, who keeps a photograph of her. She was sent to the Tamers by the Digimon Sovereigns to give them the ability to Biomerge in the real world, via the power of her partner, Dobermon (who sacrificed his life to do this).

Some events seem to suggest that Alice "passed on" prior to her appearance in the series and what was seen was actually her ghost. At one point, she is seen fading into the air as she leaves the area. Later, in Strategem, she seems to have picked up a few more tricks and still as mysterious as in her previous appearances.
