Zhuge Liang serves as a Caster-class Pseudo-Servant, formed through the fusion of the ancient strategist Zhuge Liang and modern mage Waver Velvet. This union emerged from extraordinary circumstances during the Grand Orders, where Waver’s compatibility with Zhuge Liang’s tactical intellect enabled the latter to manifest using Waver’s physical form. Though Zhuge Liang retains authority, he prioritizes Waver’s autonomy, utilizing his host’s modern-era knowledge while offering strategic guidance from the background. His personality blends Waver’s pragmatism with Zhuge Liang’s analytical rigor, forging a rational yet occasionally short-tempered demeanor. He approaches alliances with detached professionalism, openly clashing with rivals like Sima Yi—labeled a persistent irritant—while honoring historical peers such as Iskandar. Moments of introspection surface when confronting figures from his past, including Artoria Pendragon, whose legacy continues to resonate with him. During the Second Singularity: Septem, he strategizes for Alexander, deploying tactics that range from calculated enemy enticement to orchestrated pincer maneuvers. His aversion to unnecessary risk manifests in decisions to evade direct combat with berserkers like Spartacus and Lu Bu, preferring to manipulate terrain and attrition. In the Fate/Accel Zero Order event, his expertise unravels anomalies within the Fuyuki Singularity’s Holy Grail War timelines, coupled with stern warnings about the Grail’s corruptive influence. His combat repertoire encompasses team-wide defensive fortifications, offensive enhancements, and NP acceleration. Battlefield dominance is asserted through skills like *Discerning Eye*, which sharpens allies’ tactical precision, and *Unreturning Formation*, a recreation of his Stone Sentinel Maze that cripples foes with defense erosion, curse accumulations, and NP depletion. These abilities cement his role as a versatile strategist who amplifies allies while dismantling enemy cohesion. Interpersonal ties reveal layered dynamics: he harbors nostalgic respect for Iskandar, balancing camaraderie with a mentorship toward the younger Alexander. With Gray, a former apprentice, he maintains a reserved yet attentive rapport, assigning mundane tasks to sustain their connection despite shifting roles. Across chronicled events, Zhuge Liang exemplifies adaptability, weaving historical wisdom into contemporary conflicts. His strategic focus anchors efforts to decipher temporal distortions or outmaneuver battlefield adversaries. This duality—rooted in his fusion with Waver—positions him as a conduit between eras, steering crises with methodical intent while confronting the weight of shared identity.
