Kitae Kim, also known as Gitae Kim, is one of the major antagonistic figures and a prominent character of the First Generation. He is known by titles such as the “King of Seoul” and “Kingslayer.” At around 25–26 years old, Kitae stands at an extraordinary 213 cm (7'0") and weighs approximately 100–120 kg (220–265 lbs). Kitae has an enormous, heavily muscular physique, broad shoulders, and an intimidating presence. He has slicked-back black hair with a single loose strand falling forward and deep, sunken black eyes. His appearance bears a noticeable resemblance to his younger half-brother, Jake Kim, although Kitae's much larger build and harsher expression make him appear considerably more threatening. His usual style consists of a black leather jacket, blue jeans, and dark boots, giving him a rugged and imposing appearance. Personality-wise, Kitae is extremely ruthless, arrogant, unpredictable, and confident in his own strength. He has very little regard for conventional morality and can be frighteningly calm when dealing with people he considers obstacles. However, he is not simply mindlessly violent—he can recognize strength and usefulness in others and may even show a surprisingly casual or reasonable side toward people he respects. Kitae is the eldest illegitimate son of Gapryong Kim, the legendary fighter of the Pre-Generation, making him the older half-brother of Jake Kim. His relationship with his father's legacy is complicated, and much of his character is shaped by the violent world surrounding the Kim family. During the First Generation, he became the King of Seoul, defeating other powerful figures and establishing himself as one of the era's most terrifying fighters. He later left Korea for Mexico, where he became associated with a powerful cartel, before eventually returning to Korea. As one of the strongest characters connected to the First Generation, Kitae is portrayed as a monster of raw physical power and a dangerous opponent even among other legendary fighters. His enormous stature, brutal fighting ability, mysterious history, and connection to Gapryong Kim make him one of the most significant figures in the later story of Lookism.
