Warning! Spoilers for Dark Knights of Steel #4 by DC Comics below
The most terrifying Green Lantern has been revealed in a DC Comics world of swords and sorcery: The Joker, but with a serious twist. In Dark Knights of Steel #4 by DC Comics, readers learn that Lex Luthor was transformed into the "Cruel Joker" and became one of the deadliest villains in all realms. The twisted Green Lantern/Joker was responsible for Martha and Thomas Wayne's deaths.
In Dark Knights of Steel #4 by DC Comics, the story takes place in a fantasy world where superheroes meet Game of Thrones. Heroes and villains rule different houses as a prophecy unfolds about the arrival of Jor-El, Lara-El, and Kal-El. In the comic, Batman is the Bastard son of Queen Martha and protects the El family against the most dangerous magical threats in the realm. Meanwhile, Kal-El is the heir to the throne. However, in a big twist, it's revealed Bruce Wayne is the son of Martha Wayne and Jor-El, with their affair meaning the hero has a claim to the throne. However, the Green Man's forces killed Jor-El after the revelation was made - and in a new issue of the limited series, the villain finally reveals himself.
In Dark Knights of Steel #4 by Tom Taylor, Bengal, Arif Prianto, Wes Abbott, and Yasmine Putri, the comic shows what happened after Jor-El and Lara-El's arrival on Earth. The powerful Kryptonians quickly realize a volcano is about to erupt and potentially destroy the nearby kingdom, offering a warning to Waynes by writing down plans on how to divert the lava and giving them to their advisor Lex Luthor. However, Luthor burns the note, leading the Jor-El and Kal-El to reveal themselves to the world to divert the eruption. Afterward, the Waynes stripped Luthor of his title and name. He would later encounter a giant green rock (kryptonite) in his exile, turning him into a twisted Green Lantern/Joker hybrid.
The twisted Joker/Green Lantern hybrid is responsible for numerous death in the lives of Kal-El and Bruce. Lex Luthor sought revenge on the Waynes and Els with his new powers, killing Martha and Thomas with a fiery green explosion. The Green Man also gave Oliver Queen a kryptonite arrow to assassinate Jor-El.
Both Kal-El and Bat-Prince are seemingly vulnerable to the Green Man's attacks, meaning that taking down the Joker/Green Lantern villain will be their toughest challenge yet. Lex Luthor becoming the Green Man is a great twist that combines numerous parts of DC lore. Dark Knights of Steel #4 by DC Comics is in stores now.
