Sergeant Hobo 678 was in charge of Zim's training session on Hobo 13. When the time came for Zim's team to pick a leader, Sergeant Hobo 678 told them to choose carefully, as their success would depend on their leader's competence. However, Zim voted himself before the Sergeant could even finish his sentence, and won by default of silence. Zim then went on to get all his teammates eliminated, to the extreme disgust of Sergeant Hobo 678.
