Go-Jaaza-Gi

Go-Jaaza-Gi appeared in 2000 TV series called Kamen Rider Kuuga. Go-Jaaza-Gi (ゴ･ジャーザ･ギ Go Jāza Gi), otherwise known as Unidentified Life Form #44 (未確認生命体第４４号 Mikakunin Seimeitai Dai Yonjūyongō) and B10 (Ｂ群１０号 Bīgun Jūgō), assumes the form of a glasses-wearing woman in a dark green suit.

She hates to fight but she knows she must continue for her own survival and prefers killing those too weak to fight back. She is armed with a harpoon. When her turn begins after modifying herself from her default Quick Form (俊敏体 Shunbintai), she goes all out to kill 567 within five hours while leaving internet blogs proclaiming her actions minutes prior.

After slaughtering the mostly elderly 243 passengers of Rainbow Airlines in one go while posing a passenger, she kills the pilot after having him relay a message to the police of her intent. Jumping out of the crashing plane and swimming all the way back to Tokyo, she manages to severely wound Kuuga while his guard was down. After meeting with Baruba, she heads off to kill the remaining 327 at Sunflower Cruise, most of which were children.

Kuuga arrives on Gouram to stop Jaaza in Dragon Form. However, she evolves into her Herculean Form (剛力体 Gōrikitai), armed with a large sword and Kuuga in turn switches to Rising Titan Form, taking their fight into the ocean floor as he kills her.

At least one Go-Jaaza-Gi was part of a group of human-turned Gurongi created when they were exposed to N-Gamio-Zeda's miasma. Some were later absorbed by him in a last effort to defeat Kuuga and Decade. The remaining Gurongi died after Gamio was defeated.
