The Ace from Outer Space

A flashback showing Ikki, Koji and Rintaro losing a three-on-three Robattle against Shrimpy Lipowitz (Shrimpy of the Rubberobo Gang) and his Medabots leads to Ikki's surrender of Metabee's rare medal. A timely arrival by the mysterious Space Medafighter X, the number one-ranked Medafighter in Japan, foils Shrimpy's plans. X returns the rare medal to Ikki with a warning that ownership of medals should never be Robattled over. They're too precious a commodity.

This disastrous Robattle causes Ikki to drop to number four in the national Medafighter rankings. Only the top three Medafighters will represent Japan in the World Robattle Tournament. Ikki's friends implore him to resume Robattling so that he can improve his rank, but the defeat has caused Ikki to lose his confidence as a Medafighter.

Rintaro takes Ikki and Metabee to a Medabot training facility in hopes that Ikki will learn some new battle techniques and will regain his love of Robattling. However, the new-age facility, and its flaky, bearded instructor, cause Ikki some concern. Koji, Karin and Erika track Ikki and Rintaro to the training center.

When it's discovered that the instructor is really Shrimpy trying to con Ikki out of his rare medal, Shrimpy calls upon his three Medabots to initiate a Robattle. This time, Ikki is prepared. He hadn't given up on Robattling at all; he'd simply been devising ways to counter-attack each of Shrimpy's Medabots. Metabee summons the Medaforce to defeat Shrimpy's Medabots. Koji realizes that he can never triumph over Ikki in Robattle unless he finds a way to counteract Ikki's use of the Medaforce.
