Ikki Tenryou is an energetic and friendly young man who can be somewhat shy at times. Initially, Ikki does not have enough money to purchase a Medarot. However, after discovering a faulty medal in a river, he buys a model called Metabee. Despite the fact that the medal appears to be defective, as Metabee is stubborn and disobedient, a strong bond develops between them following several battles. Although Ikki does not possess all the skills required to become a skilled Medafighter, he gradually matures through his engagements in these battles.
