Tseng is a young man with a slim build, tan skin, straight, long black hair, and dark brown eyes. He has a tilak and sometimes wears his hair in a ponytail when in the field. Tseng wears the standard Turks uniform consisting of a dark suit, which includes additional accessories such as black leather gloves and stud earrings. Tseng is calm and collected. He is intelligent and insightful, possessing important intel about the planet, people, history, and Shinra. He is a stern, competent, and prudent director, deeply trusted by the company for his experience. Tseng takes pride in his duties as a Turk, aspires to act professional, adapts his personality to the situation, and leads casually. Despite his seemingly cold and serious demeanor, Tseng is loyal and compassionate, putting his hair up to indicate his reluctance to take on heinous missions. However, he tends to hide his true feelings. Tseng maintains casual relationships with his acquaintances and colleagues. He excels at managing his eccentric and reliable subordinates Reno, Rude, and Elena, who respect him and turn to him for guidance despite his sometimes callous attitude. He also built a trusting friendship with Zack, working with him on various missions, joking around with him, and eventually going against company orders in a failed attempt to save his life, a burden that continues to pain him. Tseng is close with Rufus, acts as his trusted right-hand man and bodyguard and agrees with his vision to help Shinra atone for their past by protecting the planet. He is not very close with the other Shinra executives, but they value his rational judgment and exceptional insight.
