Alice McCoy

Alice McCoy is an animated fictional character who first appears in episode 44 of Digimon Tamers. She is 11 years old with blond hair, blue eyes and a gothic lolita style of dress. Alice is voiced by Philece Sampler.

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 (he sacrificed his life to do this). After this episode Alice is not seen again.

Writings released by Chiaki J. Konaka, executive producer of Digimon Tamers seem to suggest that Alice "passed on" prior to her appearance in the series and what was seen was actually her ghost. Nothing in the series seems to confirm this, however and Konaka himself notes that it was probably just his imagination getting the better of him.

Panini Comics
The Digimon comic strips published in the UK's Wickid magazine briefly explored Alice's history, in an attempt to create some backstory for the character. Here, it is explained that she was caught up in an early digital experiment being conducted by her grandfather years ago, and was inadvertently teleported to the Digital World. She was found and raised by the Digimon Sovereign, who created Dobermon to provide her companionship. Following the arrival of the Tamers in the Digital World, she was charged with reaching them to give them the power to Biomerge in the real world, only to have her attempts repeatedly stymied by the D-Reaper's Agents. In reference to Konaka's own theories about the character, at one point during the story, Alice comments that she is "not even sure if she is alive anymore."

Although the UK comic strips are officially licensed, their story content is not moderated by any Japanese creators, so this information is not strictly canon for the animated series. In particular, there is no real reason that Alice's grandfather would be conducting an experiment related to the Digital World, as he had no reason to believe such a place even existed at the time.
