Xu·Gmun·Ba[src] (ズ・グムン・バ, Zu Gumun Ba)[1], also known as Unidentified Lifeform #1 (未確認生命体1号, Mikakunin Seimeitai Ichigō) to the police, is a spider-themed Gurongi and the first of the Xu Group to appear in Kamen Rider Kuuga.
History[]
Gmun first appeared in southern Nagano weaving a web on the 1532 MK Building, overwhelming law enforcement as he attacks them without mercy with his power to spray webbing and create claw extensions on his hands.
Crashing into the police station, Gmun slaughters the police officers until Yuusuke puts on the Arcle, being targeted by the Gurongi as he becomes Kuuga in "Growing Form" in a fight that ends with Gmun being knocked out of a helicopter several feet in the air. [Revival]
Surviving the fatal fall, Gmun reappeared to settle the score by aiding Goma in his clash with Kuuga, now in his Mighty Form. But in the end, the Xu was mortally wounded by Kuuga's incomplete Mighty Kick, screaming his intent to kill Kuuga as he exploded. [Transformation]
Kamen Rider Decade[]
World of Kuuga[]
At least one Xu·Gmun·Ba 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. [Transcendence]
World of Agito[]
Xu·Gmun·Ba was one of two Gurongi seen on the front page of a newspaper detailing the appearance of the Unidentified Lifeforms that was read by the Hikari Studio group when they arrived in the World of Agito. [Reunion: Project Agito]
Kamen Rider Wizard[]
Xu·Gmun·Ba's destruction at the hands of Kuuga (as seen in Transformation) was shown in a recollection by Amadum as he explained the nature of his world as a paradise for monsters destroyed by the Kamen Riders. [The Kamen Rider Rings]

The sticky thread that vomits from his mouth is said to be harder than steel and more supple than silk. This thread can be ejected at a high speed enough to break through the window of a police car with a single blow. He specializes in tactics in which the target is entangled with a thread and stabbed with the elastic claws growing from the back of the hand. Also, he has the ability to move while sticking to the wall. In addition to this, he possesses super-speed counter attack and supernatural power as a common ability of Gurongi, boasting vitality that invalidates even handgun's bullets, and a strong arm that gently pushes the bus.
