Saizou

"NinjaBlue~Saizou!"

Saizou (サイゾウ, Saizō) is NinjaBlue (ニンジャブルー, NinjaBurū) of the Kakurangers. He is a descendant of Saizou Kirigakure.

Kakuranger
At 22 years old, he's a constantly chattering, easily flattered man who thinks he's a lot smarter than he really is. Likes to help other people, making him popular among children. Somehow unlucky in most things. His way of talking is a little feminine. He corresponds to Sha Wujing.

Super Sentai World
When Emperor Daidas and his army invaded Earth, Saizou, alongside his team, joined with the four Sentai that came before them, the Dairangers, Zyurangers, Jetmen, and Fivemen, to defeat him.

Gaoranger vs. Super Sentai
NinjaBlue is among the Sentai warriors seen in clips when Yuusuke Amamiya (Red Falcon) lectured Gaku Washio (GaoYellow) about the past Sentai sword experts, showing him that the true sword wasn't the sharpest, but the one that feeds on courage.

Gokaiger
Years later, Saizou fought alongside not only his own team, but every single Sentai ranger in existence, against the Empire of Zangyack when it attacked the Earth in the Great Legend War. After fighting against hundreds of Gormin and their Zgormin commanders. Kaijou 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 NinjaBlue powers are later used by Joe Gibken via the Ranger Keys.

After the defeat of Ackdos Gill, the Gokaigers returned all the Ranger Keys to the former Sentai heroes. It is assumed Saizou and his teammates received their keys, allowing for them to utilize their powers once again.

Super Hero Taisen
Saizou, alongside his team (bar Ninjaman), among the majority of the Super Sentai heroes, was caught up in the "Super Hero Taisen" incident which eventually resulted in the Super Sentai teams and Kamen Riders joining forces to defeat both Dai-Zangyack and Dai-Shocker.

Ranger Key
The NinjaBlue Ranger Key (ニンジャブルーレンジャーキー) is Saizou'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 NinjaBlue Ranger Key was mainly used by Joe Gibken (Gokai Blue), who used it to fight as NinjaBlue.
 * When he, Don, and Ahim became the Kakurangers while Gai became Shurikenger when they got a Gokai Change got mixed up.
 * When the Gokaigers became the Kakurangers to escape from Action Commander Shieldon.
 * When the Gokaigers became the Kakurangers while fighting against Action Commander Bibabu.
 * When the Gokaigers became the Kakurangers while fighting alongside Ninjaman against Action Commander Juju.

After Zangyack were finally defeated, the Gokaigers gave the Ranger Keys back to their rightful owners. It is presumed that Saizou received his key and became NinjaBlue once more.
