with war, and to become more effective warriors they fastened metal armor to themselves. However, their wars decimated the civilization, and the survivors coded their memories onto hexagonal pieces of metal. These, "Medals", cloned and mass-produced by the Medabot Corporation (a corporation founded by Dr. Aki), are the Medabot equivalent of a brain and soul. The original medals, referred to as rare medals, are kept in storage because of the extreme power they have. Medarot Damashii (Medabots Spirits) Medarot Damashii, a sequel to the original series, follows Ikki and Metabee, as they face a new challenge following the events of the original series. Kam Kamazaki, a twelve-year-old boy, has designed one of the most dangerous medabots in the entire story, called Kilobots (or Death Medarot, in the Japanese version), who use the X-Medal. These Kilobots have no feelings, since the emotion part of the Medabot medal has been removed, and more strength parts have been replaced instead, and can break the rules in order to win a fight. Because they have no personality, the Medaforce is useless against them. In the first episode, Ikki loses a Robattle to Ginkai and his Kilobot when it cheats and reloads. But he soon meets Nae, a Medabot mechanic and Dr. Aki's granddaughter, who gives Ikki new medaparts in order to defeat the kilobot through using a new feature called Action Mode (later Demolition Mode is introduced as well). Throughout the season, Ikki, Erika and their new friend Zuru (who also masks as the Mystery Medafighter) battle several of Kam's friends and their Kilobots. The Mystery Medfighter's ambition is to rid the world of Kilobots, with the help of his medabot Roks. Eventually, Ginkai re-discovers the true spirit of medafighting and ceases being a rogue medafighter and returns to using Medabots. Eventually Kam realizes the error of his ways and stops trying to develop stronger and more dangerous Kilobots, choosing to remain with his Kilobot Blackbettle, who has a personality installed into her medal. The series is often criticized for the removal of several supporting characters such as Henry/Hikaru Agata/Phantom Renegade/Space Medafighter X and Arcbeetle, Rokusho, Koji and Sumilidon, Rintaro and Kantaroth, Karin and Neutranurse, Victor and Warbandit, Mr. Referee, the Rubberrobo Gang and the Chick Salesman, as well as for the fact that many of the new Kilobots and Medabots are simply slightly modified versions of the original series without relation to the
