Without its leaders, the remainder of the Justice League must battle an army of mindless clones led by a brutal clone of one of their own, in an episode that aired on this day in television history.
“Panic in the Sky” is the 11th episode of the 2nd season of Justice League Unlimited. Written by Dwayne McDuffie and directed by Dan Riba, it first aired on Cartoon Network on July 9th, 2005.
In the episode, which is part of the “Cadmus” story arc from throughout this season, the original Justice League turn themselves in (minus Batman) due to the events of the previous episode. At the same time, the crippled Watchtower comes under attack by a massive army of brainless clones of superpowered beings led by another clone, this one of Supergirl.
