[sub]Unlike regular humans, due to the experiments performed on him, Zack is a 'Super-Solider', to put it lightly. All of his senses have been enhanced dramatically, including, but not limited to, hearing, smell, sight, reflexes, and strength. He's extremely skilled with a sword, and can wield one twice his size. The holsters on the Buster Sword allow him to use junction enhancements that can be slotted into it to increase the sword's power twice fold through enhancements.

Zack himself is a master swordsman however and also well-versed in magic having come to learn several techniques and spells due to all of his training and effort enough to where he is on par with some Keyblade Wielders.

Memories and emotions serve as a major basis for boosting Zack's abilities. The process of this is the Digital Mind Wave, or the DMW. In Zack's mind, this works as a slot-machine type of device, matching up faces and memories to gain certain abilities or become stronger. The more Zack is focused on one person, the better a chance of him gaining that type of ability, but it is otherwise by random chance. In any case, the more people and friends he meets, the stronger he would become, it works similiary to Aqua Ventus and Terra's D-Links however with some differences.

Ventus: Gives him access to Ventus's Wingblade Command Style

Terra: Gives him access to Terra's Rockbreaker Command Style

Aqua: Gives him access to Aqua's Spellweaver Command Style

Angeal: Gives him access to Angeal's Rush Assault

Aeris: Gives him access to Aeris's Healing Wave

Cloud: Gives him access to Cloud's Meteor Shot[/sub]
