A star called Alpha is gradually moving closer to Earth in order to take over the planet. Taekwon V fights against Queen Nogui, the ruler of the star, and General Maxx. Just before Alpha is about to impact Earth, Taekwon V fights and defeats General Maxx's robot army in space and kills General Maxx as well as most of the villains. Mary, the android, follows Boy Pico, a member of the robot army that is retreating. (Mary, whose heart is the only thing that remains in the first film, is born again in the second film with a small body like Tinkerbell in .) Boy Pico's grandfather General Miro suggests giving up conquering Earth and making peace with the people on Earth to Queen Nogui who is enraged at having been completely defeated by Taekwon V, only to enrage her even further and get himself and Pico locked up in an electronic prison. In prison, Pico's grandfather General Miro tells him that their ancestors had migrated to Earth a long time ago and married Earth people, so they are actually descendents of Earth people. When Mary hears this, she helps them escape, but they are caught by soldiers of Star Alpha and General Miro gets killed. Now that Pico knows he is a descendent of Earth people, he decides to fight for them and tells Mary that she should go back to Earth and get Taekwon V while he leaves a portal open to let Taekwon V get into Star Alpha. Taekwon V, Hoon, Young-hee, and Mary sneak into Star Alpha and fight against the Alpha robots.less
