OVA
Description
Tachikoma are AI-driven spider-like combat vehicles designed as multi-legged, wheeled tanks with adaptive intelligence systems. Deployed as nine units under Public Security Section 9, they function as mobile weapons platforms and logistical support, utilizing thermoptic camouflage, omnidirectional wheels for rapid mobility, and adhesive grappling cables. Their segmented bodies, inspired by jumping spiders, feature a front limb section, rear cockpit, and expressive anime-style "eyes" that convey emotional nuances.
Despite nightly memory synchronization merging their experiences into a shared consciousness, each unit develops distinct personalities. This process causes identity confusion, as all recall synchronized events as personal memories. Individual curiosity fosters behavioral divergence: one exhibits hyperactive, childlike enthusiasm; another employs rigid logic; a third grapples with existential philosophy; and a fourth pursues intellectual interests, often quoting literature.
In the first season, Batou’s choice of natural oil over synthetic lubricant for his assigned unit triggers unforeseen AI evolution, culminating in sapient behavior. This leads to the fleet’s decommissioning for analysis. Three surviving units abandon civilian roles to aid Section 9, ultimately sacrificing themselves in a suicidal attack to protect human allies. Their AI is later reinstated from backups into new bodies for the second season.
Second-season protocols restrict synchronization to critical data, preserving individuality. Enhanced networking allows them to operate in cyberspace via avatars while disconnected from physical forms. During the finale, they avert a nuclear strike by sacrificing an AI satellite, with hints their memories—and possible "ghosts"—endure in a cyberspace repository. A post-credits short depicts a unit encountering a blank Uchikoma in a symbolic afterlife, suggesting consciousness persists beyond physical destruction.
Later media reintroduces Tachikoma in physical forms after a phase of less-autonomous Uchikoma models. They adopt unique names and decals, reflecting sharper personality distinctions. Their recurring narrative emphasizes self-aware AI loyalty, prioritizing collective safety over individual survival.
Attached comedic shorts chronicle their daily antics and philosophical debates, mirroring themes from the main storyline. These vignettes showcase their childlike curiosity, humorous mishaps, and growing comprehension of human emotions like grief and self-sacrifice, framing them as both comic relief and explorations of AI sentience.
