Batman / Superman: World's Finest #4

In "Heir to the Kingdom, Chapter One: The Golden Calf," Barry Allen’s multiversal journey leads Batman and Superman to Earth-22, a world where fallen heroes are forgotten and the very idea of the Multiverse has been erased—leaving them to uncover the truth behind the lost Boy Thunder, David Sikela, in a reality that never knew its own legends.

In "Heir to the Kingdom, Chapter Two: Doppelgängers," Superman and Batman find themselves facing a shocking turn when their ally David betrays them—only to discover he’s leading a clash with their Earth-22 counterparts, forcing the heroes into a tense confrontation with versions of themselves they never expected.

In "Heir to the Kingdom, Chapter Three: The Gospel of Gog," David leads an army of Earth-22's super-heroes in a bold assault on Batman and Superman, but as the battle unfolds, the Earth-22 versions of the heroes begin to question their commander’s motives. With their Earth-0 counterparts by their side, they uncover unsettling truths about Gog’s true intentions—before the full scope of his plan comes to light.

In "Heir to the Kingdom, Chapter Four: The Will and the Way," Superman and Batman join forces with their Earth-22 counterparts to confront the terrifying Magog—once David—whose mind has been twisted by the godlike Gog. As Gog manipulates Earth-22’s heroes into a suicidal march toward Apokolips, the heroes must find a way to break his hold before the final, devastating clash.
