Justice League Unlimited (Seasons 1–3)

Justice League Unlimited (2004) is the DC Comics animated series you can watch online on iFILM. Picking up where Justice League left off, it expands the roster from a core seven heroes into a sprawling organization of dozens — Superman, Batman, Wonder Woman, The Flash, and Green Lantern now share the orbital Watchtower with characters DC animation had never touched before.

Every episode throws the team into a new kind of trouble: alien incursions, shadowy government conspiracies, and in the third season, the villains finally follow the heroes' lead and organize. Kevin Conroy and George Newburn return as Batman and Superman, anchoring the show's continuity with Bruce Timm's animated DC universe that began back in 1992.

Three seasons, no filler arcs. The writing treats its audience as adults — internal power struggles inside the League, ethical grey zones, and season-long conspiracies that pay off. Stream Justice League Unlimited online on iFILM.
