Another important aspect is the story of Henry, the store clerk who sold Ikki Metabee. It is revealed that he is, quite obviously, Phantom Renegade. A running gag of the series was Henry almost telling everyone he is The Phantom, with no one ever discovering this fact. Space Medafighter X is introduced, who is another one of Henry's secret identities, the number one medafighter in Japan. Later, during the World Finals, he rarely shows up to the fights, instead sending substitutes and working behind the scenes. This being because he supposedly started The Ten Days of Darkness, which occurred eight years before the events in the series during the World Robattle Cup when Henry fought as Hikaru Agata with the original Metabee (however, the medal was different). The Medabots went on a rampage during the Ten Days of Darkness, which stopped when Henry was forced to kill his Medabot by destroying his medal.
