10-year-old Ikki Tenrio has always dreamed about becoming a top-ranked medafighter, and now that he has his own medabot he can finally pursue his dream.

In the year 2122, Ikki and children like him have pet robots called medabots, with A.I. (artificial intelligence) capabilities. They take their medabots and robattle against each other until a champion medabot team is determined.—Cliff Wade <[email protected]>

Medabots-powerful robots granted artificial intelligence through special "medals"-serve at the whims of their owner. They are more commonly used in "Robbatling," a popular combat sport where two medabots face off against one another. In its professional form, Medafighters use their Medabots to qualify for the World Tournament and fight among st the elite to gain the title of champion. Elementary scholar Ikki Tenryou has just gained his first Medabot: Metabee, an outdated model with no medal. Fortunately, however, Ikki manages to find a medal in the nearby river; but when Ikki places it into Metabee's head, the latter starts to exhibit strange behavior. Short-tempered and rebellious, he refuses to obey Ikki's orders. However, to climb the ranks to the World Tournament, Ikki and Metabee must first learn to work together, no matter how difficult the prospect may seem.—MAL Rewrite
