—Sinclair before executing Lucas Kellan

Thomas Sinclair (2339 - August 5, 2390) was the director of the Shadow Marshals and the president of the Vektan Security Agency during the events of Killzone: Shadow Fall, as well as being one of the primary antagonists, serving initially as a supporting character beforehand.

Sinclair was a former Shadow Marshal himself serving in the Second Extrasolar War, and the Helghast resettlement. He tasks Lucas Kellan with missions and objectives throughout the game. He first meets Lucas when his father Michael attempted to escape New Helghan. After saving Lucas from certain death, Sinclair took him to the Vektan side of the wall. He seems to regard the Helghast as animals and views the peace treaty as a mistake. Ruthless and calculating, he is shown to go to any lengths to wipe out the remaining Helghast, even so far as betraying and executing Lucas, who was like a son to him, to restart the war. In retaliation, Echo assassinated Sinclair during a speech as he attempts to get political will behind him.

Sinclair is voiced and portrayed by David Harewood.


A highly decorated Shadow Marshal of the Second Extrasolar War, Thomas Sinclair was active in numerous operations that were instrumental in securing the Interplanetary Strategic Alliance's victory. He was involved in the formation of the Vektan Security Agency and was mostly likely responsible for the instigation of violence and unrest to create a perceived Helghast threat. He moved through the ranks of the VSA to become agency head within few years. Many questioned this rapid rise; some claimed Sinclair used information gathered from his ties to the intelligence community as blackmail. He is a staunch patriot and idealist. This personal view is a major factor in his decision making process against Helghan.

Killzone: Shadow FallEdit

Main article: Killzone: Shadow Fall

In 2370, Sinclair helped Michael Kellan in helping him and his son Lucas to escape from New Helghan. Unfortunately, Sinclair was only able to save Lucas and Michael was killed by Helghast soldiers. Within over two decades, Sinclair became Lucas' mentor and later his superior in the Shadow Marshals.

During rising tension between the Vektans and Helghans came close to war, Sinclair sent Lucas to infiltrate New Helghan and recovering classified data relating to an ISA bio-tech weapon experiment, headed by Dr. Hillary Massar, developed on the ISC Cassandra to be use as a deterrent against the Helghans. Sinclair ordered Lucas to scuttle the Cassandra and destroying the experiment from falling into Helghan hands. However, Massar willingly defected to the Helghans and allowed her bioweapons research to be use against the Vektans. Sinclair placed a high priority for Massar's capture.

Following an attack on the VSA headquarters by the Black Hand under their leader Vladko Tyran, Sinclair dispatch Lucas to again infiltrate New Helghan and locating Tyran. Lucas soon returned to the VSA and informed Sinclair of Chancellor Hera Visari's alliance with Jorhan Stahl and their intentions to ignite another war with Dr. Massar's bio-weapon. Sinclair, however, was very displeased from hearing from Lucas that he decided to side with Visari's daughter Echo on calling for the VSA to stand done from further provoking war with New Helghan. Refusing to consider Lucas' words, Sinclair had Lucas sent to Helghan, where Massar had finished preparing her bio-weapon, and to take custody of Massar. Lucas did not followed Sinclair's order and allowed Echo to kill Massar, causing Sinclair to brand the Shadow Marshal a traitor.

Sinclair soon commanded the ISA into launching an assault on Jorhan Stahl's base. He was then contacted by Lucas into aborting the assault as Stahl was about to activate Massar's weapon, but refused to listen. Consequently, Massar's weapon destroyed every ISA ship. Sinclair survived and managed to board Stahl's base, killing Stahl and mortally wounding Lucas. Sinclair revealed his intentions to Lucas that he actually intended to restart the war against the Helghast and planned to use Massar's weapon to finally eradicate the Helghast threat. After discussing his plan, Sinclair executes Lucas Kellan.

Sinclair returned to Vekta as a "hero" and began rallying the Vektans for war against the Helghast. During a speech, Sinclair was assassinated by Echo, thereby preventing a new war from beginning.


  • "I never thought it would be you to betray me Lucas, be the one I couldn't trust. "
  • "You're too important to this operation. Goddammit you're too important to me."
  • "Look buddy, I don't like it any more than you, but until we cross the wall, it's their rules."
  • "We think it's Helghast encryption."



  • He is voiced and modelled after David Harewood and despite having an American accent, his voice actor is British.
  • He seems to distrust politicians, as shown in the beginning of The Shadow.
  • His callsign is Pulsar.
  • He is the announcer for the VSA in Warzone, alongside his counterpart, Anton Saric.
  • He appears to have been wounded rather severely in the war, taking a glancing shot to the head (if his uneven widow's-peak is any indication) and possibly having a bionic arm, given the harness he appears to be wearing in cutscenes.
  • According to the Dossier about Sinclair (a collectible which can be found during the campaign), his first name is Thomas. However, in the last mission, "The Savior," there are two TV screens visible from the uppermost level of the park broadcasting Sinclair's speech which state his name as Elliot Sinclair.
