Eon family

The Eon family is the legendary family that defeated the General. Only Eon, Marty, and his father have been mentioned, but all members are great warriors and martial artists. The General's forces wiped out the family through the years leaving Marty the sole blood heir to the family legacy. Their ancestral home is a huge fortress surrounded by bamboo forest. Underneath the home is the family's ancestral training ground that includes wood training drones and tests to hone the family's martial arts skills. The home has fallen into great disrepair since the death of Marty's father.

Eon – Eon was the hero who ended the Second Robot War by destroying the General, but unfortunately he died in the process. His weapon, later called the fist of Eon, was passed down through his family for 100 years. He has only spoke to Marty once, although it was a hologram of him that actually spoke to him in The Temple of the Iron Soul where he once trained to learn control of the fist.

Marty – Marty is the lead character of the series. While scavenging for robot parts to sell he finds the Fist of Eon and puts it on, although unwillingly. Marty later discovers that he is a direct descendant of Eon, who 100 years prior to the series start defeated the General and ended the Robot War. Endowed with the power of the fist he must fight the evil forces of the general. He was originally named Iron kid in the original Korean version. Marty is the last descendant of the Eon family and is also the last heir of Eon. He is the final carrier of the Fist. He's shown to possess a natural talent for fighting and grows stronger as the series goes on.

Gaff – An ancient robot who has served the Eon family for more than 130 years. He safeguarded the fist for one hundred years until its successor, Marty, was found. Somewhat a mentor to Marty and has watched over the Eon family for years and defended the family from the general's forces as best he could. His weapon is the dragon sword.

Master Zhang – An unofficial member of the Eon family Master Zhang waited for the fist's successor at the family's ancestral home. He is a martial artist master who has trained several generations of the Eon family. Although he is quite old he is still a formidable teacher and opponent but can be quite silly.

Charlie – Charlie is another unofficial member of the Eon family. In flashbacks it is revealed that he was a servant of the Eon family and a close friend of Marty's real father. During an attack he flees with Marty and raises him as his own, per his real father's instructions. He was later captured by Black Beauty shortly after Marty flees to Crystal City.
