Zack Fair -⋆˚★˖°

Zack's signature appearance is a tall, well-built man with spiky black hair, and the iconic sky-blue "mako eyes" common to SOLDIER members. In his most iconic appearance as a SOLDIER First Class, he dresses in black uniform, wearing gloves and boots, and wields the Buster Sword. He also has an X-shaped scar on his cheek, a silver stud earring in his left ear, and a single lock of hair hanging down in front of his face.

Zack is upbeat, optimistic, kind, and driven, beaming with enthusiasm and energy even under dire circumstances. His energetic nature is coupled with a short attention span and restlessness, earned him the moniker "Zack, the Puppy" when his mentor spoke of him to others. Zack is extremely affable, befriending people quickly with ease, and gaining the trust of allies. He is similarly flirty and charming with women. Over time, the dire circumstances Zack faced did not make him bitter or pessimistic, but rather matured him away from his more restless behavior, maintaining his positive and hopeful attitude even in his latter days.

Zack's core motivation is to become a hero and protect his honor, his guiding principle. When fighting Wutai, he affirms loyalty to comrades while equivocating as to which side is right, but spares the captain's life rather than act out of cruelty. When he eventually clashes with former comrades, he does so reluctantly, after trying each time to save them. His quest to see good in people and to support them allows him to inspire, but sometimes lead to naivete. Zack's drive is a direct contrast to Genesis, who seeks heroism for the glory, validation, and superiority coming with it, where Zack seeks to surpass only himself. Though he grew cynical of his own past ambivalence as to what he was fighting for, his commitment to honor and heroism stuck with him to the end, reiterating his mantra in his last stand.

Zack had exceptional skills in swordsmanship and hand-to-hand combat. This allowed him to defeat both Angeal and Genesis, two of the most powerful SOLDIER members, and present a challenge to Sephiroth despite ultimately failing. Zack also had tremendous durability, fighting an entire Shinra army alone in his last stand, and taking out Fort Tamblin's defenses by himself. His combat skills led Hojo to consider him worthy of being used in tests against powerful monsters.

Zack was competent in using magic granted to him by materia. His most notable other attacks came from Digital Mind Wave, wherein he copied the skills from his allies, as well as monsters and creatures after gaining their summon materia and items, respectively. Beyond this, Zack showed competency with a sniper rifle, something he was averse to using, but credited to Shinra's Auto-Assist System rather than his own skill.

Zack possessed strong physical fitness, demonstrated in his squats. A personal hobby of his, Zack was described as "unbeatable" at squats, and Lazard even worried they were "all he was good for" before sending Zack off to Wutai. Zack is also capable in many harsh terrains, such as snow mountains, something he owed to him being a "country boy". Zack also demonstrated handywork, building Aerith's flower cart.
