Description
Gladiolus Amicitia, eldest son of the noble House Amicitia, inherits his family's sworn duty to protect the kings of Lucis. As heir, he serves as primary shield and bodyguard to Prince Noctis Lucis Caelum, embracing the life-pledged responsibility to safeguard the Lucian royal household with pride.

Childhood training sessions at the Citadel fostered Gladiolus's initial negative view of Noctis, whom he perceived as uncooperative and spoiled. He resented being assigned as the prince's protector, preferring direct service to King Regis like his father. This perspective shifted when his younger sister Iris wandered into woods outside the palace trying to see Noctis. After Noctis safely returned Iris yet claimed sole responsibility for her disappearance to shield her from repercussions, Gladiolus learned the truth from Iris. This act earned his respect and forged a bond of mutual trust with Noctis, evolving into a brotherly relationship.

Gladiolus possesses a tall, muscular build, standing 198 cm (6'6") tall, with amber eyes and brown hair shaved at the sides. A long scar crosses his left eye, obtained years prior while protecting Noctis from an assailant. His appearance changes significantly after a ten-year timeskip, featuring longer hair tied in a ponytail and faded tattoos. A large tattoo of a bird of prey covers his back and arms, symbolizing his role as the King's Shield; male members of the Amicitia line receive this upon formally assuming duty.

Despite his imposing physique, Gladiolus exhibits a cheerful, outgoing demeanor. He freely expresses opinions, acts as a pillar for the group's objectives, and employs blunt humor. An avid outdoorsman, he collects camping equipment and appreciates nature. His loyalty to Noctis transcends duty, rooted in deep personal bonds. Yet he holds Noctis to high standards as future king, becoming confrontational when perceiving complacency, sometimes escalating to physical altercations. He is protective of his sister Iris and flirtatious with women.

In combat, Gladiolus wields greatswords and shields, favoring raw strength over magic. Possessing high physical durability, he excels in close-quarters combat. His techniques include generating shockwaves by slamming shields and throwing greatswords for ranged attacks. As a survival specialist, he tracks, scavenges, and manages the party's camping gear.

Key events demonstrate his development. After failing to protect Noctis from Ravus Nox Fleuret during an Imperial base infiltration, Gladiolus temporarily separates to undergo rigorous training under Marshal Cor Leonis. He confronts the legendary Gilgamesh, overcoming self-doubt about his capabilities. Following Lunafreya's death, he confronts Noctis over reluctance to wield the Ring of the Lucii, prioritizing Noctis's responsibilities as king over grief. During the decade-long World of Ruin, Gladiolus travels Eos eliminating daemons while awaiting Noctis's return, reuniting fully committed to defending him in the final confrontation at Insomnia.

His relationship with Noctis remains central, evolving from childhood friction to profound mutual reliance. Gladiolus consistently prioritizes Noctis's safety and growth, balancing protector duties with honest counsel even during conflicts, underscoring their bond as brothers beyond formal duty.
