==Synopsis==

Ultraman Zero appears and battles Black King but realizes that the plan failed, Nackle escapes with Black King and brings Rui as a hostage in another dimension. To save Rui, X and Zero join forces.
==Plot==
At the Operation Base X, Rui takes a test run on her cotton candy gun while Gourman teaches Daichi of the super-dimensional theory. Soon, the lab team tries to enact an experiment to turn monsters into Spark Dolls based on Ultraman X's Xanadium Beam. While on a journey to the test site, a black monster attacks the convoy. While Xio members attack the monster, it seemed that it tries to target Xio Aramis for bringing the Spark Dolls.
Daichi runs away from Aramis, unknowingly spotted by Gourman and hides to transform into Ultraman X. While X fights the monster, a poncho-wearing alien named Alien Nackle Bandero approaches and defeats Wataru, trying to steal the Spark Dolls but stops when his monster, Black King, is in a pinch. He grows up and assist it in fighting X, overpowering him but once he tried to take the Spark Dolls, a giant appears from the wormhole, having hunting Bandero in various dimensions. Gourman knows him as the "infamous" Ultraman Zero. Zero attacks Black King and manages to torn off his horn. But Bandero nonetheless goes to another dimension by picking the Aramis, with Rui inside and leaves with Black King. Zero wants to kill them but X warns that a hostage is inside, angering him and goes to the same dimension Nackle escape to.
Rui finds himself in an alien world, where Black King receives a new cybernetic horn while Bandero contact his client. Spotting the Ultlaser, she grabs it and tries to attack but loses control. Despite that, it gives her time to run with the Spark Dolls in Aramis. Rui's communication though manages to reach Earth and Xio base, but the source of the broadcast is Area T-9C, which turns out to be the "resting place" for his parents in the Ultra Flare. As Daichi talks to X, Zero intrudes the X Devizer and wants to meet them at the space. Zero reveals to X of his background and reveals Rui's location on Planet Guillermo but insists to go himself. Returning to base, Daichi sees everyone trying to create an Ultimate Zero card that allows the user to go on any dimensions.
At Planet Guillermo, Bandero finds Rui and offer her a place by making him weapons to sell but she refuses and runs away. Bandero turns huge but Ultraman Zero enters and attacks him, with Black King Drill Custom enters to join his master. As the Ultimate Zero card completed, Gourman silently delivers it to Daichi as he transforms and use the card to assume Ultraman Zero Armor to go to Planet Guillermo. As he arrives, X takes on Black King Drill Custom, using Ultimate Zero, Gomora and Eleking Armor while Zero attack Bandero with Strong-Corona and Luna-Miracle forms before finishing him off with the Zero Twin Shoot while X finishes off Black King Drill Custom with his Xanadium Beam
As the battle ended, Rui picks Black King's Spark Doll and takes a picture with Zero, having infatuated to him, with X joining them in the picture. Zero bids farewell and wishes to meet again sometime later while X returns to Earth with Rui.
