A mad scientist named Dr. Cops is bent on world domination and is kidnapping world-class athletes in order to make an army. In response, Dr. Kim creates the super robot Robot Taekwon V and has his eldest son, taekwondo champion Kim Hoon pilot it. Hoon either pilots V mechanically or by his movements that includes his Taekwondo style. Joining Hoon is his young friend Kim Cheol (aka Tin-Can Robot Cheol) who wears a tea kettle with eyeholes on his head for his alter ego and Hoon's girlfriend Yoon Yeong-hee who like Hoon also utilizes Taekwondo and can pilot the Taekwon V.
Relationship to Mazinger ZEdit
As admitted by Kim Cheong-gi, there are several elements from Mazinger Z. An obvious point out is the strong resemblence that Taekwon V has from its source of inspiration. Several of the main characters also physically resemble the main characters of Mazinger Z. Cheong-gi stated that besides wanting a hero for the Korean children, he wanted Robot Taekwon V to be a Korean version of Mazinger Z, giving the robot the ability to use Taekwondo kicks to appeal to the South Korean audience.
