Weiss was one of the intelligent holograms created by Hirogen engineer Donik to serve as prey for their holographic training simulations. He was modelled after a human Starfleet officer. He was later liberated by Iden and became part of his rebellion.
- The holographic Weiss may have been created from a template of Lieutenant Weiss, an officer stationed aboard Voyager, although this was never substantiated.
- Weiss was played by actor Spencer Garrett.
