Fictional last words in Avatar media

The numerous deaths across all different media of Michael Dante DiMartino and Bryan Konietzko's Avatar universe have yielded many memorable last words.

Avatar: The Last Airbender (2005-2008)

 * Admiral Choi! Prepare to meet your fate!
 * Who: Hahn
 * Source: Episode: 120, "The Siege of the North, Part 2"
 * Notes: Says this line before charging towards Admiral Zhao, who easily dodges the attack, and sends Hahn falling into the water below. Whether this killed him is unknown.


 * I have to do this.
 * Who: Yue
 * Source: Episode: 120, "The Siege of the North, Part 2"
 * Notes: Says this line before sacrificing herself, giving up her human life to revive the Moon Spirit. She then becomes a spirit herself.


 * It can't be!
 * Who: Zhao
 * Source: Episode: 120, "The Siege of the North, Part 2"
 * Notes: Says this line right after discovering the moon has returned. He is then killed by the Water Spirit.


 * You dare suggest I betray Iroh? My firstborn? Directly after the demise of his only beloved son?! I think Iroh has suffered enough. But you? Your punishment has scarcely begun!
 * Who: Fire Lord Azulon
 * Source: Episode: 207, "Zuko Alone"
 * Notes: In Zuko's flashback, shortly after the death of Iroh's son Lu Ten, Ozai demanded that Iroh be passed over as heir to the throne, inciting his father's fury. As such, Azulon wanted to make Ozai feel the pain of losing a firstborn son by ordering him to take the life of Zuko. The next morning, Azula casually tells Zuko that Azulon passed away in his sleep - in truth, Ozai forced Ursa to poison him.


 * I'm not leaving. I can't. I've spent too long trying to find this place. There's not another collection of knowledge like this on earth. I could spend an eternity in here.
 * Who: Professor Zei
 * Source: Episode: 210, "The Library"
 * Notes: As the members of Team Avatar escape the library from Wan Shi Tong, Zei tried desperately to grab as many books as he could. Eventually, he simply declared that he would rather "spend an eternity" in the library than lose all of his life's work. Zei ended up dying in the library, inadvertently fulfilling his wish.


 * Don't worry, Katara. I'll be fine.
 * Who: Jet
 * Source: Episode: 217, "Lake Laogai"

 * I'm sorry, Katara.
 * Who: Aang

 * Please...
 * Who: Avatar Roku
 * Source: Episode: 306, "The Avatar and the Fire Lord"
 * Note: While trying to stop an erupting volcano with the help of Fire Lord Sozin, Roku is suddenly struck by the volcano's poisonous fumes. After pleading for Sozin's help, he and his dragon Fang die from the pyroclastic flow that hits them both, only for Roku to be reincarnated immediately after as Aang.


 * It's me. Take me as your prisoner.
 * Who: Kya
