Lt. Sharon Valerii ( Boomer )

Lt. Sharon Valerii ( Boomer ) from Battlestar Galactica played by Grace Park.

Lt. Sharon Valerii ( Boomer ) is a fictional female Cylon (2003) pilot in the Battlestar Galactica television series who was portrayed on screen by Grace Park. In the new series of Battlestar Galactica, Boomer claims to be from Aerelon, although she is a Cylon spy. There are many copies of Sharon, one based on-board the Galactica, another who helps Helo survive Caprica.


Boomer doesn't realise she is a Cylon, she believes she is but is unsure. Boomer visits Dr. Gaius Baltar and asks him to test the Cylon detector out on her. The Cylon detector works but Baltar can't bring himself round to telling her she is a Cylon. Baltar tells her she's human and he tells Adama that the device needs to be corrected.

Boomer is sent on a mission with Lt. Margaret 'Racetrack' Edmondson. Whilst onboard the Cylon Basestar, she is confronted by other copies of herself. When she returns to the Galctica, she shoots Commander William Adama on the command deck of Battlestar Galactica. Boomer is subsequently arrested and charged over the murder. When Boomer is being led down a corridor to be returned to prison, Cally ( Battlestar ) appears from nowhere and shots Boomer. The spirit of Galactica-Sharon is reborn on a Resurrection Ship and struggles to fit in.


Lt. Helo gave up his seat for Dr. Gaius Baltar as Helo believed that Gaius's intelligence would be of benefit to the fleet more than Helo would be. Helo was forced to survive on the damaged Caprica. Helo was being watched by a Number Six clone, an Aaron Doral clone and a Boomer clone when Boomer was instructed to go and interact with Helo which she duly did. Helo honestly thought it was Boomer and referred to her, he wasn't to know it was anyone else.

Caprica-Sharon seduces Helo as they survive on the planet avoiding the Cylons. She convinces Helo that she is pregnant with their child before leaving the planet in a ship that Kara had used to get to Caprica from Galactica. The child, a baby girl is subsequently born. President Laura Roslin has visions of a girl which she believes to be Helo's child. It is discovered that Laura's cancer can be cured with the blood from the child which they try.

The Boomer character that was with Helo and subsequently became his lover, mother to his child and then wife was named Athena to distinguish between the two Boomers. Athena is led to believe her daughter has died but President Laura Roslin had hidden the baby amongst the fleet. Sadly, during the rescue of the colonials on New-Caprica, the baby Hera falls into the Cylon hands. When Boomer as part of a visiting party to the Galactica, the truth of Hera is revealed to Athena who then becomes angry. Adama confronts Roslin to find out the truth of the baby in which she reveals the truth. (The Eye of Jupiter)

Athena kept having visions of seeing Athena in a theatre hall running away and into the arms of a Number Six clone who then with Dr. Gaius Baltar walk into the bright light. One day whilst looking after Hera, the little girl runs off and is picked up by Natalie. Athena thinking that the dream has come real, shoots Natalie dead. Boomer is confined to the Brig.

Kara's Hospital Escape

When Lt. Kara Thrace ( Starbuck ) was escaping from a Cylon hospital, she ran into an operating room where it looked like the original, biological Boomer was connected to a machine. Kara didn't save Boomer as she didn't have time and believed her to be dead anyway.

Cylon Civil War

When Brother John Cavil tried to organise the Cylons around his thinking, he manipulated Boomer to change sides to what her Cylon model was thinking and then win the argument. It didn't go too well for John as Number Six wreaked revenge by killing John Cavill only for him to resurrect and then get his own back.

Lt. Boomer - Original Series

The casting of Grace Park in the role of Lt. Boomer was controversial. The character was both gender and race swapped, instead of being of African-American Descent, Boomer became a female of Korean descent. The original character was player by Herb Jefferson.

Lt. Boomer was an integral part of the series, his involvement did seem to reduce in the second half of the series. Instead of Boomer, Lt. Sheba became more prevalent in the series.
