- "Surging Shark! GaoBlue!"
- ―GaoBlue's roll call[src]
Kai Samezu (鮫津 海 Samezu Kai) is GaoBlue (ガオブルー Gao Burū) of the Gaorangers.
Kai is a 19-year-old (29 as for the Great Legend War in Gokaiger) freeter, whose previous jobs included pizza delivery and working as a clerk in a bowling alley. He was chosen as a Gaoranger around the same time as Sae. He is a very energetic and playful guy, but he hates being treated as a child, especially because Sae is younger than him. He is skilled at bowling and studied under a professional bowler, Don Katayama.
His motto is "Never give up!" which he frequently uses to encourage Soutarou. He is in charge of forming the right arm for the Gaorangers' mecha formations. After the final battle, he became a clerk in a surf shop although he and Soutarou initially planned to run a Chanko shop together to "dominate the world." He also seems to be interested in Sae.

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 GaoBlue powers are later used by Joe Gibken via the Ranger Keys.

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 GaoBlue was defeated as part of a group of surviving Blue warrior keys by Gokai Blue and Super Gosei Blue.
After Zangyack were finally defeated, the Gokaigers gave the Ranger Keys back to their rightful owners. Kai received his key and became GaoBlue once more.
