- "Noble Eagle! GaoYellow!"
- ―GaoYellow's roll call[src]
Gaku Washio (鷲尾 岳 Washio Gaku) is GaoYellow (ガオイエロー Gao Ierō) of the Gaorangers.
Gaku is a 23-year-old (33 as for the Great Legend War in Gokaiger) former Self Defense Force pilot. He was the first Gaoranger to be chosen who worked a year alone with only Tetomu. Tetomu recruited him during a flight mission, and he became missing in action. Because of this, he bleached his hair to become less recognizable. As a pilot, he is good at skydiving and English and his hobby is playing the ukulele. At first, Gaku was very serious and humorless, he was upset that Kakeru has been chosen as leader instead of him and he was demoted to second-in-command. As time went on, Gaku opened up, and became especially close to Kakeru, often teasing him good natured.
Gaku is the one who insisted that the Gaorangers refer to each other by color and not use their personal names. Being his Power Animal a bird, Gaku refuses to eat bird meat (he seems to be the only one to have this tendency; neither Soutarou nor Kai have shown any problem eating cow meat and fish, respectively). He is in charge of forming any leftover parts for the Gaorangers' mecha formations. After the final battle, he returned to the Air Force and his natural hair color. Gaku has a tendency to speak in English with a clear Japanese accent still in his words.

After fighting against hundreds of Gormin and their Zgormin commanders. AkaRenger noticed the fleet moving towards them, he gathered all the Rangers together and gave them the order to sacrifice their powers to wipe out the first invasion's armada.

The GaoYellow Ranger Key (ガオイエローレンジャーキー Gao Ierō Renjā Kī) is Gaku Washio's personal Ranger Key and what became of his powers after he along with the rest of the 34 Super Sentai sacrificed their powers to end the Great Legend War.
This key along with the majority of the Ranger Keys were collected by the Red Pirates and later used by the Gokaigers. The GaoYellow Ranger Key was mainly used by Luka Millfy (Gokai Yellow), who used it to fight as GaoYellow. It was also used by Captain Marvelous (Gokai Red) on one occasion.

The Gaoranger keys, along with all the Ranger Keys of the first 33 Super Sentai, were briefly taken by the Black Cross King and turned into Ranger puppets that were fought by the Gokaigers and the Goseigers. Splitting up, the puppet GaoYellow was defeated as part of a group of surviving Yellow warrior keys by Gokai Yellow and Super Gosei Yellow.
After Zangyack were finally defeated, the Gokaigers gave the Ranger Keys back to their rightful owners. Gaku received his key and became GaoYellow once more.
