Holographic avatar
From Battlestar Wiki, the free, open content Battlestar Galactica encyclopedia and episode guide
A holographic avatar is a digital representation of a person in the virtual world of the holoband. Avatars are created by scanning devices upon purchasing a holoband headset.
While a majority of avatars are controlled by a user in the real world, Zoe Graystone, who inherited her father's brilliant computer skills, found a way to create a fully sentient online holographic avatar of herself, Zoe-A, with all of her memories and experiences - essentially a twin who existed only in cyberspace and could interact with Zoe's separate representation there. After her death in a suicide bombing caused by her boyfriend, Ben Stark, Zoe-A is uploaded by Daniel Graystone into a robot body, the first Cylon known as Zoe-R (Caprica pilot).
