Admiral Ackbar is a fictional character in the Star Wars science fiction saga. A member of the amphibious Mon Calamari species, Ackbar was the foremost military commander of the Rebel Alliance who led major combat operations against the Galactic Empire and was later integral in the formation of the New Republic. Ackbar played a supporting role in the 1983 film Return of the Jedi, and later became a prominent character in the novels, comics books and other media of the Star Wars Expanded Universe.
With his distinctive salmon-colored skin, high-domed head and large fish-like eyes, Admiral Ackbar was realized in Return of the Jedi through the use of a half-body puppet and slip-on mask, depending on the camera angles used. He was portrayed in the film by puppeteer Timothy M. Rose, who asked to play the part after he was impressed with a sculpt of the puppet. Ackbar was voiced by Erik Bauersfeld, who made up the voice he believed matched the character after looking at a photo of Ackbar.
The Ackbar character has been received positively by critics and fans. The line "It's a trap!", which he says during a scene in Return of the Jedi, was one of the most popular lines from the Star Wars films and became a popular Internet meme.
