Resurrection (RDM)
- For information on a book based on the Original Series universe, see Resurrection (book).
The consciousnesses or programming of some Cylons who are destroyed can be revived in a process known as resurrection.
Humanoid Cylon Resurrection
When a humanoid Cylon's body ceases to function, their consciousness can be transmitted (or "downloaded") into a duplicate humanoid Cylon body (Miniseries).
For resurrection to occur, the dying agent must be close to a resurrection point, or a Humanoid Cylon's consciousness risks being permanently lost. The transmission method of a Cylon's consciousness has not been explained, but a form of wireless is probable. Resurrection points identified include the Cylon homeworld, a Resurrection Ship, or other facility, probably located on a planet where numerous agents would congregate. A rebirthing facility may have existed on occupied Caprica. Within each resurrection point is at least one Cylon rebirthing tank, where a duplicate body is immersed in a thick opaque substance to await download (Downloaded).
While humanoid Cylons appear to be able to be resurrected indefinitely, two problems can occur. Repeated downloads can cause pain and other unexplained symptoms. A Cavil reports severe headaches after one resurrection, and a sensation that felt like "a white hot poker in my skull" in a following instance (Exodus, Part I). This might be a subjective or singular experience, as a Number Three finds a download to be rejuvenating (Downloaded). Far more threatening is if a humanoid Cylon's memories have become compromised, corrupted, or otherwise tainted (based on the perspective of other Cylons). If that occurs, the consciousness might not be downloaded, instead being "boxed," a drastic measure equivalent in Cylon society to our capital punishment. Conversation in "Downloaded" suggests that this is either very rare or has never occurred apart from the boxing of the Number Threes (Rapture).
Very little is known about the mechanics of downloading. With a proper setup, a complete download can be performed in no longer than two days. This measurement comes from the download of the Cavil previously mentioned in "Exodus, Parts I & II". However, too little is known to determine whether this is among the quickest or the lowest amounts of time required to download, as the audience is not privy to the logistical or technological barriers in initiating that download.
Fighter Resurrection
The semi-sentient personalities of Raiders also can be retrieved. This allows the Raiders to return to fight with greater tactical awareness (Scar).
The Raider known as "Scar" may have been one such Raider to learn master fighting tactics. The Scar personality scores many Colonial kills before its permanent destruction.
Raider resurrection also requires a Resurrection Ship in order to take place.
