The French Deception - S2.E16

Ikki and Koji become suspicious when they learn that Tem France has won all of their matches by default because their opponents have failed to turn up. When Metabee's medal goes missing, the gang suspects that Team France have stolen it, but find that their opponents are able to dress up like other people, making them hard to catch. As the gang tries to recover their medals, Team France kidnaps Karin, so Samantha has to stand in as Space Medafighter X, but as the Robatlle prepares to begin, the real Space Medafighter X (a.k.a Phantom Renegade) has switched places with one of the members of Team France and so the team has to forfeit the match, meaning that Team Japan advances automatically.
