The Flash #20 — Mike Del Mundo Cover (2025) | Bad Moon Rising: Part One

The Flash #20 — Mike Del Mundo Cover features a striking, heavily stylized portrait of Wally West as the Flash, presented in multiple overlapping images against an intense orange and yellow background.

The main Flash figure occupies the center of the cover, wearing his iconic red mask and costume while looking directly toward the viewer. Behind him are additional large images of the Flash, creating a repeated or multiplied effect that visually reflects the issue's story, in which Wally has divided himself into hundreds of versions known as “Temps.”

A brilliant white lightning bolt dominates the lower portion of the artwork, surrounded by crackling yellow energy. The composition uses warm orange, gold and yellow tones throughout, giving the cover an energetic, almost sun-blasted appearance.

The top of the cover identifies the story as “Part One — Bad Moon Rising,” while the large black THE FLASH logo stretches across the upper section. The DC All In branding, issue number 20, and legacy number 820 appear at the upper left. The bottom-right text reads “ARMY OF ONE,” emphasizing the central concept of Wally multiplying himself into an army.

The story begins a major Flash event in which the moon becomes a battlefield between Wally West and a reborn Eclipso, who has taken control of the Moon and assembled an army of his own.
