Kim Kaphwan was going to be playable under the pseudonym "Mr. Taekwondo" (similar to Takuma's persona as Mr. Karate in Art of Fighting). However, veteran designers protested the idea, resulting in Kim being replaced with a different fighter. While several SNK's Taekwondo characters were considered (such as Jhun Hoon, May Lee, and Seo Yong Song from Buriki One), a fellow developer suggested creating a female Taekwondo fighter with Kim's "hot-blooded" personality, which eventually formed the basis for Chae Lim. To set her apart, Chae was made to be the struggling student who was not as adept as her peers or mentor but possessed a dominating determination. Ureshino depicts her relation with Kim as a "father-daughter relationship", adding that she is a young woman with Kim's potential.
