S03E08 Crisis on Earth-X (I)
As Barry and Iris celebrate their wedding, the festivities are interrupted when villains from Earth-X launch an attack on the event. The heroes unite, joined by allies like Citizen Cold, The Ray, Felicity Smoak, Iris West, and Alex Danvers, to confront their most dangerous foes. Leading the charge are Earth’s greatest champions – Green Arrow, Supergirl, The Flash, and White Canary – as they rally their teams to protect the world from imminent destruction. The saga continues in Arrow S06E08 Crisis on Earth-X (II), The Flash S04E08 Crisis on Earth-X (III), and DC's Legends of Tomorrow S03E08 Crisis on Earth-X (IV).
