However, in the middle of the battle, Belial brainwashed Rei into being his servant, and by extension had Gomora attack the Ultra Brothers. Ultraseven received the most critical hit and was mortally wounded. Although the arrival of Ultraman Dyna and ZAP Spacy managed to get Rei back to his senses, an exhausted Seven made a final attempt by throwing his Eye Slugger as a distress call before collapsing to his injuries. The Eye Slugger arrived when Zero's training was completed and had his relation to Ultraseven undisclosed. This reveal prompted him to race towards the Monster Graveyard, but he was too late, as his father died in his arms before he helped the resistance win against Belial's army. After the battle, the Plasma Spark was returned to its position and unfroze the Land of Light and its residents. While Zero was grieving for his father's death, Seven returned and reunited with him.
