Eli Knable (Earth-6531)

Eli Knable is a German mercenary and former associate of the Riddler who helped him in his assaults.

Invasion of the Virago Casino
Eli Knable was one of the mercenaries helping the Riddler during his invasion at the Virago Casino in Gotham City, New Jersey, as his second in command. While Riddler kidnapped Rumi Mori, Knable battled Batman, but he was defeated after an intense fighting.

Interrogated
He was taken into custody by the GCPD officer Sgt. Renée Montoya, but the police force was approached by S.H.I.E.L.D. agent Jasper Sitwell, who revealed Eli was under their jurisdiction from that moment onward. Taken to a S.H.I.E.L.D. base in Connecticut, Eli was brutally interrogated in exchange of information regarding the Riddler by the orders of Director Nick Fury himself.

Batman was able to track the S.H.I.E.L.D. agents, and took Knable to interrogate him himself at an undisclosed location. There, Batman discovered the mercenary was following the Riddler out of fear rather than money, and that he plotted to target S.H.I.E.L.D. itself. He also revealed about the Lady of Dublin, a ship in Annapolis, Maryland, where the Riddler was enacting his plans. Batman eventually beat Knable down, leaving him unconscious and with a concussion.
