Swan Shiratori

"The pure white, healing étoile! DekaSwan!"

Cignian Swan Shiratori (白鳥スワン, Shiratori Suwan) / DekaSwan (デカスワン, Dekasuwan) (36, 50): Nickname, "Swan-san" (スワンさん, Suwan-san), and is known as "The Immaculate Healing Star".

Dekaranger
She is Kruger's assistant from the Planet Cigno, though Swan herself is half human. She's the one who provides the Dekarangers with their arsenal, and constantly amazes the others with her amazing intellect.

Swan can transform into DekaSwan. Although she says it is her policy to only do it once every four years, in Episode 49, she attempts to transform again when a Batusroid breaks into her command center. It has been suggested that Doggie and Swan may be "more than just friends", but they both would hastily deny it.

Her surname, Shiratori, can also be read hakuchō, meaning swan. Her number is either 7, (which is represented by the geometrical figure of a heptagon instead of a number), or 99, (the heptagon vaguely resembles the character for "white" (白, shiro), which is one stroke short of "100" (百, hyaku)).

Gokaiger
Swan fought in the Great Legend War, along with the first 34 Super Sentai teams. She, along with everyone else, sacrificed their powers to destroy the Zangyack armada. DekaSwan's Ranger Key, along with those of the 9 other Extra Heroes, ended up in the hands of Basco ta Jolokia.

The copy of DekaSwan appeared when Basco united his nine remaining Extra Hero copies, his Black Knight key having been taking by Gai in his failed attempt to gain the greater power of Gingaman, when he was confronted by Gorou Hoshino (OhRed†). The Extra Heroes would then fight the Gokaigers again, who wished to take the Ohranger's greater power rather than just be given it. DekaSwan and DekaMaster fought GokaiRed. The Extra Heroes were taken down by the Ole Bazooka. DekaSwan's key, along with the rest of the Extra Heroes was claimed by Gai.

When the Gokaigers first transformed into Extra Heroes, in their fight against the Dogormin, Ahim (GokaiPink) became DekaSwan.
