Zero finds himself trapped within a universal gap and faced against an impostor Ace. Following the battle, Darklops Zero was restrained once more by Herodia, remembering a figure named "Kaiser Belial" before deactivating. Rei was restrained after his failed attempt to intrude the alien base but was rescued by none other than his alternate self. Unlike the prime Rei, alternate Reimon was never able to control his powers, forced into the state of Reionic Burst until the original Rei punched Reimon, thus deactivating its Reionic Burst mode. Rei revealed that he lost his Rayblood instinct after Hyuga threw Seven's Eye Slugger, creating a scar on his chest which symbolizes the former's friendship with ZAP SPACY members. While searching for Rei, Hyuga instead finds his Neo Battle Nizer and an entrance to the alien base made by Litra. Although the fake Ace was destroyed, Zero try to find an escaped but was halted by Seven and Ultraman impostors.

Ultraman and his comrades from M-78 (including a new Ultraman, Zero, the son of Ultra Seven) join forces with other allies to fight a massive army of giant monsters led by the evil Ultraman Belial.
