Bertrand Eldon was the former executioner at Blackgate Penitentiary turned vigilante known as the Executioner.


Early life

For 20 years, Bertrand worked at Blackgate Penitentiary executing criminals. Years later, he realized that all those he executed were innocent and were set up by a combined cabal of ADA Angus Stanton, detective Stu Donnelly and judge Raymond Calverick.[1]

Rampage as the Executioner and death

In 2019, feeling extremely horrible with himself and remorseful for the innocents he murdered, he donned the guise of the "Executioner" and attacked the three corrupt law enforcement starting with electrifying ADA Stanton. Later, he set up a trap that resembled a firing squad to kill Stu Donnelly, which he succeeded in but also accidentally shot Sophie Moore. Searching resources for the third execution method, he runs into Batwoman while searching for hydrogen cyanide, but his car knocked her out giving him the possibility to steal the gas. He would try to kill Judge Calverick in the courtroom but got interrupted by Batwoman once again. He attacked her but he is shot dead by Jacob Kane. His death caused a dead man's switch to trigger and make hydrogen cyanide fill the room, which was his plan for Calverick all along.[1]
