Václav Koller

Václav Koller (pronounced [ˈvaːtslaf]) is an underground augmentation specialist based in Prague, Czech Republic. He owns a book shop named The Time Machine in Prague, and his clinic is in an underground area below the shop, accessed through a secret bookshelf door.

Koller acts as Adam Jensen's personal neuroplastic surgeon during his stay in Prague.

Background
Koller is an eccentric engineer who has used his skills to augment himself extensively and deals with both standard and controversial augmentations.

He has associations with many of the factions in Prague, including organized crime. In particular, he is under the protection of the Dvali crime family. It is revealed that their leader, Radich Nikoladze, has a secret leg augment, so Koller maintains it and is given protection in return. However, Otar Botkoveli is unaware of the reason behind this protection, so he tries to get to Koller as a way to get to Nikoladze.

Koller also reveals he does not agree with Talos Rucker's philosophy that they should take a peaceful approach to making things better, as Rucker was "making us [Augs] look like wimps" and is happy that he is now dead. When pressed about it, he will simply say that he felt Rucker was not the solution and they need a leader who will actually fight the discriminatory laws, like the Human Restoration Act.

Trivia

 * Jensen pronounces Koller's first name with a soft "c" instead of the proper "ts". Even Koller himself pronounces it this way about half way into the story, when he hails Jensen over to fully calibrate his system to be compatible with his experimental augmentations.
