Caesar

Caesar sitting at Zoe-R's feet (CAP: "Rebirth").

Caesar is the Graystone family's dog. He was the puppy of Daniel Graystone's previous dog. He was allowed in Daniel's lab and appeared to sense that there was a sentience in the U-87 robot (CAP: "The Imperfections of Memory"). In an attempt to convince the U-87 to identify itself as an avatar of his daughter Zoe, Daniel gives the robot a handgun and orders it to shoot Caesar. It complies, but the gun is loaded with blanks, sparing the dog. Zoe was aware of this because her Centurion body could sense the gun's weight was too low to be filled with real bullets; otherwise, she might have turned it on Daniel (CAP: "Ghosts in the Machine").

Notes

• Caesar can be seen clearly in the pilot episode, in the Graystones' living room just after Daniel kicks Lacy Rand out and revokes her security clearance. [1]
• "Caesar" is a Latin word meaning "head of hair," although it later becomes synonymous with Julius Caesar.
• Caesar and Jake (in New Caprica) were possibly portrayed by the same dog.
