Synopsis
Enemy Ace does not feature in the modern-day plot involving Booster Gold and Dr. Will Magnus. Instead, his appearance is localized within the issue's backup feature "The History of the DCU, Part I." As Harbinger's cosmic recording orb projects a chronological montage of Earth's historic protector figures, Hans von Hammer appears in a fresh flashback panel, depicted flying his iconic red Fokker Triplane alongside other historical DC icons including Anthro, Silent Knight, Jonah Hex, and the golden-age Justice Society, visually anchoring his place in the definitive timeline of Earth-One.
