Ikki Tenryou is a lively and easygoing boy, although a bit timid. At first Ikki is unable to afford a Medarot. 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.
