Watch Science Ninja Team Gatchaman online: Episode 102 Reverse! Checkmate X

A message comes in that a mecha has appeared, but since he can't contact Nambu, Ken goes out based on his own decision. But that mecha is bait to lure the team away from Nambu. Meanwhile, Joe visits an unlicensed doctor. The Female Commander appears, unnoticed by Joe. The doctor watches Nambu, who has locked himself up in his house, pushing his analysing work. Nambu is abducted by Galactor. Joe, who has visited the doctor again, sees the commander, follows her and arrives at the mecha where Nambu is held. Nambu says to the triumphant Katse that it's a pity that he can't publish the true face of Katse, which he has been grasping for a month. At that moment, Joe comes storming in in order to save Nambu. He is shot by the Megazainer, the transformation is undone and he remains unconscious. He is surrounded by Galactor rifle muzzles. At that instance, the Science Ninja Team, who entered because of Joe's message, mows down the Galactor members. Katse aims the Megazainer again at the Science Ninja Team. Regaining consciousness, Joe shoots the wire of his airgun into the muzzle of the Megazainer, making it explode. The mask goes flying through the explosion's shockwave and Katse covers his face. Nambu trusts them the secret that Katse should have been born as twins, one male, one female, but that he is a mutant who was born as a hermaphrodite. Just then X shows his form before Nambu and the others. Ken hesitates for a moment to throw his boomerang at the fleeing Katse. The Science Ninja Team shudders at the existence and power of X.
