Nicholas Stephen Tyrol is the infant son of Cally Tyrol and Brendan Costanza, originally believed to be the son of Galen Tyrol.

He was born some time between the end of "Lay Down Your Burdens, Part II" (c. day 680) and "Battlestar Galactica: The Resistance, Part I" (c. day 727), and is dedicated to the service of Ares and Apollo (Battlestar Galactica: The Resistance, Part X).

Chief Tyrol tells Sharon Agathon that Nicholas is named after Cally's grandfather (Exodus, Part I).

When Cally finds out that her husband is a Cylon, she attempts to kill herself and her son. However, Tory Foster, under the guise of dissuading her from her actions, takes Nicholas into her arms, only to space Cally herself (The Ties That Bind).

He was originally thought to be a Cylon/human hybrid[1], because his father Galen Tyrol is a type of Cylon (Crossroads, Part II). Some time later, young Nicholas is treated for renal failure, and Galen reminds the medical staff has to give special care for young Nicky because of his believed half-Cylon nature. But after Layne Ishay compels Dr. Cottle to tell Galen more about his son, Doc Cottle later reveals that Galen Tyrol was not the biological father (A Disquiet Follows My Soul).


  • Nicholas Tyrol was named after producer David Weddle's maternal grandfather.[2]
