Ep 4. Tabula Rasa (2)

As the Justice League regroups following their near-defeat at the hands of the powerful android Amazo, they are called into action once again when a mysterious creature begins wreaking havoc in the Arctic. The team, consisting of Superman, Batman, Wonder Woman, Green Lantern, Flash, and Martian Manhunter, sets out to investigate the origin of the creature and put a stop to its destructive rampage.

Meanwhile, Lex Luthor is up to his old tricks, working with Dr. Wade Eiling to create a new weapon that can take down the Justice League once and for all. Using a special satellite, Luthor and Eiling are able to track the movements of the League and are quickly able to determine their next target: a research facility where the creature is being studied.

As the League arrives at the facility, they come face to face with the creature, which has now grown to monstrous size and appears to be impervious to their attacks. While the creature continues its rampage, Luthor and Eiling launch their attack, using a weapon that is powered by Superman's own energy and designed to take him down for good.

Despite their best efforts, the League is unable to stop the creature, and Superman is forced to take extreme measures in order to save his teammates and stop the rampaging beast. But even as they celebrate their victory, the League realizes that Luthor and Eiling are still out there, plotting their next move.

As they prepare for the next strike, the League also grapples with the aftermath of their battle, as they struggle to come to terms with the decisions they were forced to make and the sacrifices they had to endure in order to save the day. Finally, as the episode draws to a close, the League sets out once again, ready to face whatever challenges lie ahead.
