Forces of evil, chaos, and destruction await. Not even protectors like Superman, Batman, Wonder Woman, Green Lantern, the Flash, Hawkgirl or the Martian Manhunter may have a chance alone. But together as the Justice League, they are a metahuman force (and a hope) to be reckoned with.

Although several actors reprised their voice roles from the shows "Batman" (1992) and "Superman" (1996), conspicuously absent is Timothy Daly, who voiced Superman. He became unavailable after landing the lead role in the TV series "The Fugitive" (2000). However, this is the fourth consecutive animated series starring 'Kevin Conroy' as Bruce Wayne/Batman: the forementioned '92 series, _"New Batman Superman Adventures, The" (1997)_ and "Batman Beyond" (1999) (Not including guest appearances on "Static Shock" (2000) and "The Zeta Project" (2001)).

Continuity: In "The Man Who Has Everything" Batman states that the Black Mercy has eaten through Superman's costume. When the plant is removed Superman's costume is intact.
