During a battle with an enemy called the Iron Nail, the Super-Soldier Serum within Rogers’s body was neutralized, causing him to age rapidly to match his chronological age of over 90 years. No longer able to take part in field missions but retaining his sharp mind, Rogers decided to take on a role as mission coordinator, organizing the Avengers’ plans of attack from the mansion, while appointing Sam Wilson as his official “replacement” as Captain America. When various Avengers and X-Men were inverted into villains and several villains inverted into heroism due to a miscast spell by the Scarlet Witch and Doctor Doom, Rogers not only coordinated the efforts of Spider-Man and the inverted villains, now called the “Astonishing Avengers”, but also donned his old armor to battle the inverted Falcon, until the heroes and villains could be returned to normal with the aid of the White Skull (the inverted Red Skull).
