Lieutenant Otis Hacks, callsign "Bugspray," operated as an elite trooper and second-in-command of Fort Casey’s K-12 Roughnecks. When Major Henry Varro, the unit’s commander, was arrested, Hacks stepped into the role of acting leader. He survived the fort’s evacuation after a bug attack alongside Ratzass and Holy Man, later rescued by Lieutenant Daugherty’s A-01 team. During the chaos, Hacks saved Trig from a warrior bug, forging a bond that evolved into a romance aboard the starship *Alesia*. Their relationship deepened when Trig revealed the emotional weight of her custom sniper rifle, urging him to bury it in her hometown if she fell—a request he deflected, insisting she survive. Tasked with locating the vanished *John A. Warden*, Hacks volunteered to aid Trig in confronting the Queen Bug but was barred by the air vent’s narrow confines. After the *Warden* crashed on Earth, he joined Varro’s assault on the Queen’s chamber. Discovering Trig’s body, he was ambushed and fatally wounded by a warrior bug. Wielding her rifle, he stalled advancing bugs to cover Varro’s advance, simultaneously honoring Trig’s self-imposed mission to kill one bug for every civilian lost in her hometown’s destruction. He fell in this final act. Known for camaraderie with Ratzass—teasing his teammate’s unsuccessful overtures to Ice Blonde—Hacks led with pragmatic decisiveness, prioritizing mission success even when it demanded personal risk, such as remaining behind to secure objectives during pivotal operations.
