An Avatar is a virtual representation of a participant in a Virtual World. Other than insignificant enhancements, such as better clothes, or more makeup, avatars are digitally identical to the participant on whom the avatar is based. In "Pilot", Joseph Adama stepped into a booth that appeared to scan him, which used that information to create his avatar.
- Heracles stole the avatar of Chiron, and impersonated him. ("There is Another Sky")
- Zoe, while in the V-World pretending to be another girl named Rachel, suggested that she made her avatar look like Zoe Graystone on purpose. She also mentioned that additional avatars cost cubits, implying that modifications to avatars cost money ("Know Thy Enemy")
