Future's Past

There are only eight teams left standing at the quarter-finals of the World Robattle Championships. Much to their dismay, Ikki and Koji learn that Spyke has been asked by Space Medafighter X to take his place on Team Japan, not wanting to be caught by the police. Koji angrily begins to whip Spyke and Krosserdog into shape with some last-minute training, with disastrous results. Spyke runs away, upset.

When Ikki and Rintaro find Spyke, they also find Patra of Team Egypt. Angered when Rintaro mentions that Hikaru Agata is his medafighting inspiration, she lures Rintaro into a sparring match, and she soundly defeats Kantaroth. She tells Ikki that no one should mention the name of Hikaru Agata after he caused the 10 Days of Darkness at the World Championships eight years ago. Ikki remembers that Henry has mentioned this so-called "Forgotten Robattle" before.

Ikki tries to learn more about the 10 Days of Darkness from Henry, who is mysteriously vague about what he knows. He lends Ikki a tape of the World Championships from eight years ago. Unfortunately, the tape has been mysteriously erased.

At the Championship quarter-finals, the battle is terribly one-sided, with Patra easily defeating Sumilidon. Metabee is saved from defeat by a last-second sacrifice from Krosserdog. Summoning the Metaforce, Metabee narrowly manages to defeat Cleobattler. Admitting defeat, Patra and her teammate Joe Swihan agree to tell Ikki the terrible secret of the 10 Days of Darkness: a medabot owned by Hikaru Agata led the other medabots on a riot which turned the stadium into a sea of fire. That medabot... was Metabee!
