13th Hunter Chairman Election arc
Following Teradein's decision to arrest Illumi and Hisoka, Latoon was sent to stop the Needle People and follow one of the blimps dispatched by Killua. Upon hearing of the crushing defeat suffered by one, possibly two of the teams who joined the hunt, Bushidora Ambitious remarks that it is not a job for amateurs and suggests that Teradein send out a warning to the Hunters going after the Needle People. However, Latoon does not answer the phone, prompting Bushidora to take matters in his own hands. Later, Loupe Highland bursts into Teradein's office and informs him that all the members of Bushidora's team and of the one previously pursuing the Needle People have been killed. Teradein confirms Latoon's death in an announcment video message to everyone in the Hunter Association.
