Pieter Burke

Pieter Burke is a high ranking Belltower officer and the primary antagonist in Deus Ex: Human Revolution - The Missing Link.

Background
According to an email on Tiffany Kavanagh's computer, Burke was a former US marine who was dishonorably discharged. He is described as charismatic and a natural leader, but he also have sexist tendencies. The specifics of his service record is almost entirely classified.

After discovering the stowaway Adam Jensen aboard the Hei Zhen Zhu cargo ship, Pieter tasked his second in command, Netanya Keitner with interrogating Jensen. It was revealed later that she assisted him in escaping, due to her role as an Interpol double agent. After docking at the Rifleman Bank Station, Burke proceeded to relay instructions to his top scientists, and unlocked a hidden elevator, unaware of Jensen's presence.

After having his spare augmentations stolen and discovering Keitner's defection from Belltower, Burke placed the facility on alert and began filling the prison cells and labs with toxic gas in an attempt to kill all potential witnesses. After Jensen made his way through all of his forces, Pieter then made a last stand against Adam in a hangar containing a 80-X Boxguard and several Belltower guards.

Regardless of whether Jensen killed or spared Burke, his subordinates are promply forced into retreating by Garvin Quinn impersonating him. Burke is most likely arrested by Interpol for his involvement in the Hyron Project, if he survives the encounter with Jensen.
