Dinosaur Alien Mission Arc
After Shion Izumi appeared in the Gantz room, Nathan and his friends were seen searching for a way to get out, and like most of the other new members, Nathan did not wear his Soft Suit Coming off as tourists, Nathan and his friends spoke English during the entire cause of the mission, heavily criticizing Japan for being "Crazy." It is unknown whether the four of them knew how to speak Japanese.
Near the beginning of the mission, Nathan and several other new Gantz Tokyo members was attacked by several Velociraptor Aliens, but was saved when Hiroto Sakurai, Kenzo Sakata and Daizaemon Kaze intervened.
Nathan and his friends were later seen seeking cover when Yoshikazu Suzuki and Kei Kurono fought off the T-rex Aliens on the Gantz Bike. When the Kappe Alien made its second appearance, Nathan and his friends jumped in hoping to defeat it, but they were all easily defeated, leaving Kaze to finish the fight.
When Kurono finally finished off the Boss Dinosaur, Nathan and his friends surrounded Kurono while cheering. Before being teleported away however, Nathan and several other new Gantz members were shot dead by the Vampire Bosses.
