What is the title of episode 4, where the gang visits Kyoshi Island?

The title of episode 4, in which the gang visits Kyoshi Island, is “The Warriors of Kyoshi.”

It is the fourth episode of Book One: Water in the original animated series. Aang, Katara, and Sokka stop at Kyoshi Island, where they encounter Suki and the Kyoshi Warriors, an all-female group modeled after Avatar Kyoshi’s legacy.

The episode introduces Suki, develops her relationship with Sokka, and shows Sokka confronting his dismissive attitudes toward women warriors. After the group trains him, he recognizes that the Kyoshi Warriors are highly skilled fighters. The story also features the giant eel-like creature Unagi and an attack by the Fire Nation.

This episode is commonly confused with “The King of Omashu,” which is episode 5, or “Jet,” which appears later in Book One. “Imprisoned” is episode 6.
