Zack
Zack comes off as goofy, cheerful, flirty and extraordinarily easy going – not exactly the image one would associate with somebody from SOLDIER. His philosophy that you only need to meet someone once to become good friends with them describes his personality in a nutshell. Despite his friendly attitude, Zack is an excellent fighter, capable of dispatching enemies with the strength of many men. Although he is strong, he will not fight unless it is necessary, and will take care to avoid permanent casualties where possible.
