Zack is a secret playable character unlocked by finishing the game with all the Final Fantasy VII characters. He functions more or less as a clone of Cloud in the arcade, versus, and minigame events. Like Cloud, he fights both hand-to-hand and with the Buster Sword, and has renamed versions of Cloud's techniques, including Meteo Shots, High Braver, True Cross-slash, and Unseen Omnislash.
Zack's fighting style is identical to Cloud's fighting style even his unique ability to wield the Buster Sword and to utilize few of his Limit Breaks. However the names of Cloud's Limit Break was later renamed to his own moves. His win animation is identical to Cloud's win animation.
In Kingdom Hearts Birth by Sleep, a slightly younger version of Zack appears in the Olympus Coliseum world. He wears a Hercules-based version of his SOLDIER uniform and uses his original sword from Crisis Core -Final Fantasy VII-. He is shown fighting Terra, talking with Ventus, and flirting with Aqua, in the similar manner he flirted with Aerith in Crisis Core -Final Fantasy VII-. He even asks Aqua out on a date. He retains his habit of doing squats. During the credits of the final episode of Birth by Sleep, he stands in the doorway of the Coliseum (much like he did at the end of Final Fantasy VII: Advent Children) watching Phil stand on Hercules while Hercules is doing push-ups. While Zack is in the doorway, he spots a single black feather falling, signifying the presence of Sephiroth.
According to an interview with Famitsu magazine, Tetsuya Nomura stated Zack was included due to his status as a character from the past in Final Fantasy VII, to tie into Birth by Sleep taking place ten years before Kingdom Hearts. He is the only Final Fantasy character (aside from moogles) to appear in the game because Nomura felt the series would have too many side stories, which could confuse some players. A remix of the "Successor" theme from Crisis Core, titled "A Date with Fate", is featured in the game.
He appears in Kingdom Hearts Union χ[Cross], on several medals.
