In the 2004 series she was once again a fighter pilot and mechanic. Her real name was Sharon Valeri and used the callsign Boomer. She was later found to be a Humanoid Cylon sleeper agent, although being a sleeper she did not realize this herself until an exact replica of her got on board the Galactica and shot Adama. Another copy of Boomer was found by Helo, a pilot trapped on Caprica.  She helped him escape, falling in love with him in the process. Being a cylon she was imprisoned when the pair rejoined the fleet.  She helped the fleet avoid Cylon attacks, and rescue other refugees from Caprica.  She became pregnant through an unmarried relationship with Helom and gave birth to a cylon-human cross breed. Her cylon title was Number 8.

'''Baltar''': Baltar is a traitor to the colonials. In the original series he was a member of the Quroum of Twelve, who helped the cylons attack the colonies.

In the 2004 version he was a timid scientist who became the vice-president, and later the president.

He created a defense grid around the twelve colonies that the cylons were able to hack. He was seduced by a humanoid cylon (number 6) who appeared to him but not to anybody else. During his brief presidency the fleet built a city on New Caprica. This was captured by cylons and Baltar was forced to sign the surrender of the colonies. When the people from New Caprica were rescued Baltar was captured and forced to stand trial.
