Otis Hacks, callsign "Bugspray," holds the rank of lieutenant and second-in-command of Fort Casey’s K-12 Roughnecks. After Major Henry Varro’s arrest, he steps into the role of acting commander. Surviving Fort Casey’s evacuation alongside Ratzass and Holy Man, he is rescued by Lieutenant Daugherty’s A-01 unit. During the escape, he rescues Trig from a Warrior Bug, sparking a bond between them. Aboard the starship *Alesia*, their relationship deepens into romance, culminating in an intimate moment after shared emotional exposure. Trig gifts him her family-crafted sniper rifle, asking him to bury it in her hometown should she perish. He deflects her fatalism, insisting she survive. When tasked with locating the vanished *John A. Warden*, he volunteers to assist Trig in facing the Arachnid Queen but is physically unable to follow her into a narrow air vent, leaving her to confront the threat alone. After the *Warden* crashes in the French Alps, he advances with Varro toward the Queen’s lair. Discovering Trig’s lifeless body, he reclaims her rifle and stalls encroaching Warrior Bugs to buy Varro time. Mortally wounded in this defiant stand, he sacrifices himself to hold off the swarm, honoring Trig’s pledge to avenge her destroyed hometown by continuing her kill count. His final act emphasizes unwavering loyalty to both ally and duty. Physically, Otis is Caucasian with brown hair and green eyes, characterized by a mix of roguish charisma and tactical ruthlessness. No expanded backstory or additional appearances exist beyond his 2012 film portrayal.
