Dr. Anton Koenig was the lead virologist of Gentek and responsible for its major projects conducted in New York City. After the second outbreak occurred, Koenig worked with Blackwatch and experimented on various infected creatures. He was eventually recruited by Alex Mercer and became one of his Evolved.[1]


Early lifeEdit

It is unknown when Koenig started working for Gentek. During the second outbreak, Koenig became responsible for many major projects in NYZ. He was also part of Project Orion, Blackwatch's second attempt at creating Super soldiers.[2]

Eventually, he was contacted by Alex Mercer and was recruited into his army of Evolved. Koenig started to work undercover, deliberately hiding sensitive information from Blackwatch while recruiting more scientists for Mercer's army.[1]

The Test SubjectEdit

"The raw data we 're collecting is like nothing I've ever seen before!"
―Koenig seeing the initial data recorded from Heller test.[src]

Koenig operated on James Heller following his infection, and was fascinated by the fact that he was still alive despite being flooded with the virus. Wanting to put Heller through a series of tests, his fascination grew after seeing the initial data recorded, as he had never seen anyone like Heller before.

When Col. Douglas Rooks gave the order to destroy Heller, Koenig objected vehemently, instead advising Heller to consume more infected to survive, a choice which put him at odds with the Colonel. After Heller escaped from the lab, he targeted Anton not knowing that he was working with Mercer.[1]

Aiding HellerEdit

Eventually, Heller cornered Koenig at one of the bases. Koenig tried to convince Heller that he was trying to help him by revealing the locations of a Blackwatch project, codenamed Orion. Heller believed him and set out to destroy the project. However, after Heller consumed one of the leading scientists he learned that Koenig was observing him in order to measure his strength, and that he now knew how to kill him. Enraged at this act of betrayal, Heller contacted the doctor and told him that he was coming after him.[1]


"I'm what you could've of been. What you were suppose to be. I'm going to prove that to Mercer. Prove he's mistaken about you. And when he sees how flawed you are... I'll be there, watching, while you die."
―Koenig to Heller, after revealing his powers. [src]
Koenig WP 2

Koenig, preparing to fight Heller to the death.

Koeing contacted Blackwatch to evacuate him, but Heller managed to destroy the soldiers guarding the base where he was hiding. During the evacuation, Koenig boarded one of the gunships and ordered the pilot to attack Heller instead of evacuating. However, Heller destroyed the gunship and tried to consume Koenig, only to be attacked and discover he was one Mercer's Evolved.[1]

Koenig stated that Alex Mercer required someone inside Gentek to get information. He then began to mock Heller, claiming that he wanted to prove to Mercer that he should be his second in command, and to do that, he had to kill Heller.[1]

The two then fought to the death. Eventually, however, Heller overpowered Koenig and consumed him, gaining the knowledge that Mercer had spies in both Gentek and Blackwatch.[1]
