Voltar the Invincible

Dr. Kaff (or Dr. Cops; 카프 박사 in Korean), an evil scientist bent on world domination, creates an army of giant robots to kidnap world-class athletes and conquer the world. To fight off this attack, Dr. Kim creates Robot Taekwon V. Kim Hoon, the taekwon-do champion eldest son of Dr Kim, pilots Robot Taekwon V either mechanically or through his physical power by merging his taekwon-do movements with the robot. Comic relief is provided by Kim Hoon's younger buddy, elementary school student Kim Cheol.
