Eric Koenig

Eric Koenig's first appearance was in Sgt. Fury and the Howling Commandos vol. 1 #27 (February 1966), and he was created by writer Stan Lee and artist Dick Ayers.

Eric Koenig received an entry in the All-New Official Handbook of the Marvel Universe A to Z: Update #3 (2007).

Eric Koenig was a member of the original Howling Commandos and fought alongside the team during World War II. He was a pilot as well as a trainer and was a very anti-Nazi German, as the Nazis killed his sister. He was the replacement of Dino Manelli, who was away on a special mission, and then replaced Izzy Cohen when he was a prisoner of war. Upon Cohen's return, Koenig stayed as a member of the team. In issue #65, "Eric Koenig, Traitor!", Koenig seemed to have been exposed as a Gestapo plant, and his apparent treachery was part of the storyline from then on. This later turned out to have been a complicated double agent operation by the High Command, and in issue #79, Koenig was finally confirmed to be a loyal fighter for the Allies.[1][2]

After the war, Koenig was one of the Howlers that joined Nick Fury in forming S.H.I.E.L.D. A Life Model Decoy of Koenig appeared and was part of the Deltite affair, but destroyed itself after being captured and scanned by Tony Stark.[3]

When S.H.I.E.L.D. was decommissioned and its agents auto-transferred to the newly founded H.A.M.M.E.R. during the "Dark Reign" storyline, Eric remained with H.A.M.M.E.R. This was despite the fact that 1200 agents who were Fury loyalists (including Dum Dum Dugan and Gabriel Jones) resigned and formed the Howling Commandos PMC. It later transpired that he was working for them from within, and aided in a heist that saw the HCPMC (now owned by Fury) raid a number of H.A.M.M.E.R. Helicarriers, and bolstering their ranks when over 3000 H.A.M.M.E.R. agents defected to their side.[4] He is later killed in a battle against HYDRA. Gabriel Jones is also one of the many S.H.I.E.L.D. fatalities along with Eric.[5]

Eric Koenig first appears in the Agents of S.H.I.E.L.D. episode "Providence", portrayed by Patton Oswalt.[6][7] He was assigned to Nick Fury's secret S.H.I.E.L.D. base, Providence, and assisted Phil Coulson and his team following S.H.I.E.L.D.'s downfall. However, he was murdered off-screen by Hydra double agent Grant Ward, and his body hidden in a ventilation duct until Skye found it.[8]

Oswalt returned in the season one finale "Beginning of the End"[9] as Eric's twin brother Billy Koenig, who oversees the S.H.I.E.L.D. base, the "Playground".[10]

In addition to appearing as Billy in the second season, Oswalt also portrays Eric and Billy's other brother Sam Koenig in the episode "...Ye Who Enter Here".[11] Sam helps Billy protect Inhuman Raina from Hydra agents until Skye, Melinda May, Lance Hunter, and Antoine Triplett arrive.[12]

In the season four episode "Hot Potato Soup", two more Koenig siblings are revealed:[13] Thurston Koenig, a slam poet activist who is not a S.H.I.E.L.D. agent as he refers to them as a bunch of "sheep" for allowing Eric to die, and an older sister named L.T. Koenig (portrayed by Artemis Pebdani). L.T. got her younger siblings to join S.H.I.E.L.D. and constantly picks on them. Billy, Sam, and L.T. try to hide the Darkhold from the Watchdogs and Holden Radcliffe, but they discover too late that Agent May was replaced by one of Radcliffe's LMDs. By the end of the episode, the Koenigs confirm that they are all human, though they were part of S.H.I.E.L.D.'s original LMD program.[14]

In the season seven premiere "The New Deal", the agents travel back to 1931 New York City and meet the Koenig siblings' grandfather, Ernest "Hazard" Koenig, who runs a speakeasy that would go on to become an S.S.R. asset and S.H.I.E.L.D. safe house under the pseudonym Gemini. One of his employees turns out to be Wilfred "Freddy" Malick, the father of future Hydra leader, Gideon Malick.[15] Koenig is given a glimpse of the future when he meets the Chronicom Enoch and is brought aboard the agents' airship, Zephyr One, to help save Freddy from rebel Chronicoms. After the S.H.I.E.L.D. agents leave 1931, Koenig hires a stranded Enoch to become his new bartender in exchange for information how he, his speakeasy, and his descendants will help S.H.I.E.L.D. in the future.[16]
