Ep 5. This Little Piggy

In Justice League Unlimited season 1 episode 5, titled "This Little Piggy," the show's focus is on Wonder Woman as she is transformed into a pig by Circe. The episode opens with the Justice League members enjoying a day off in Gotham City. Wonder Woman is initially hesitant to join in on the fun, but Batman convinces her to let loose for once. As they are walking through the city, they come across the villainous sorceress Circe, who has a bone to pick with Wonder Woman. Using her magical powers, she transforms the Amazon princess into a pig, and whisks her away to her island.

The rest of the Justice League members attempt to locate their missing friend, but their superpowers seem to be of no use against Circe's magic. They even go to the trouble of seeking out the help of Madame Xanadu, a magical fortune teller, who informs them that there is only one way to break Circe's spell and return Wonder Woman to her normal form - a man must profess his love for her. At first, Batman steps up to the plate since he has a romantic history with Wonder Woman, but ultimately, it is The Flash who must take on the task.

Meanwhile, Circe has taken Wonder Woman back to her island and imprisoned her in a pen with other animals. Using hallucinogenic herbs, she makes Wonder Woman believe that she is nothing more than a mere pig and will be living out the rest of her days on Circe's island. The Amazon princess must find a way to snap out of the spell and escape her captor's clutches.

In one of the episode's most memorable scenes, The Flash disguises himself as a suave Frenchman named Jacques, and professes his love for the pig that he believes to be Wonder Woman. The hilarious moment is amplified by the fact that the other League members are watching through surveillance equipment, trying to contain their laughter.

As The Flash makes his way to the island, he is joined by Superman, who is on a mission to retrieve their lost friend. The two heroes arrive at the island, and after a brief battle, they are cornered by Circe. It is at this moment that Wonder Woman, having finally snapped out of the spell, makes her appearance. She confronts Circe and defeats her before the group return to Gotham and Wonder Woman transforms back into her normal self. The episode ends with the League members returning to their daily routine, grateful that their teammate is safe and sound once again.

Overall, "This Little Piggy" is an entertaining and light-hearted episode that showcases the unique bond between the members of the Justice League. The comedic moments, coupled with the action-packed battles, make it a standout episode in the show's first season. While it strays slightly from the typical superhero formula, it ultimately delivers a strong message about the power of friendship and the lengths that we will go to save those that we care about.
