Medabots:Sumilidon

Rosewood Private School student Koji (In the Japanese version, he goes to Seidō Gakuen (青銅学院), meaning Bronze Institute) is the mollycoddled and rather snooty son of an extremely rich family. Something of an ace medafighter, Koji and his medabot Sumilidon are legendary for never losing a robattle. Koji and Ikki are rivals, but manage to co-exist together because of their crush on Karin. Koji always trains hard with his Medabot, Sumilidon, trying to master the technique known as the Shadow Sword, taught to them by Space Medafighter X. He thinks of himself as Karin's boyfriend. He's afraid of any insect, due to collecting a mantis egg sack as a child and forgetting about it, which lead to the egg hatching into a number of mantis that frighten him. He was even fightened of the Medabot Spidar, calling it a big bug, although he seems to either not care of Metabee's appearance of a Hercules Beetle, or doesn't see the resemblance. He, along with Ikki and Space Medafighter X, participate in the World Robattle Tournament as Team Japan.

Medabots:Brass

Erika is a friend of Ikki who also attends the same Junior High School. She is a strong-minded girl who is always bossing Ikki around. However, she also has a sweet feminine side and a soft spot for Ikki. Erika is also the reporter for the school's newspaper and will do anything for a scoop and is always looking for a story. Because of this, she tends to follow Ikki and Metabee around time to time because of their ability to find trouble. It is speculated that she has a crush on Ikki due to jealosy when Ikki flirts with Karin (season 1) and Ms. Nae (season 2). Her Medabot, Brass, is her camera girl.

Ikki Tenryou(天領イッキ Tenryō Ikki), is a lively and easygoing boy, although a bit timid. At first Ikki is unable to afford a Medabot. But after finding a medal in a river, he manages to buy a model, which is named Metabee. However, the medal he found appears to be defective, as Metabee is stubborn and disobedient. In spite of this, a strong bond grows between them after several robattles. Though Ikki is not a full-fledged Medafighter, he gradually matures through the Robattles he engages in.
