Admiral Ackbar
Admiral Gial Ackbar is a fictional character in the Star Wars franchise. 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. Ackbar played a supporting role in the 1983 film Return of the Jedi, and later became a prominent character in the novels, comic 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, has become a popular Internet meme. Ackbar's first name, Gial, was not established until the April 2012 release of the Star Wars reference book The Essential Guide to Warfare.
Admiral Ackbar was designed for the film Return of the Jedi, the final entry in the original Star Wars trilogy. However, before the May 1983 debut of that film, the character made his first chronological appearance in a series of Star Wars newspaper comic strips by Archie Goodwin and Al Williamson. There he was portrayed as the leader of the alien species Mon Calamari, who were allies of the Rebel Alliance in their conflict with the Galactic Empire. The Mon Calamari are a species of fish-like, amphibious humanoids with salmon-colored skin, webbed hands, high-domed heads, and large fish-like eyes. Ackbar's back story was not explained in Return of the Jedi, but has since been established in Star Wars books and other media since the film was released.
