They are closely followed by the Anti-Bio android Bio Hunter Silva, who uses them and his tracking of Bio Particles to likewise reach Neograd and retake Balzion for his own. Shuichi Kageyama, the son of Doctor Man during his previous life, likewise sneaks in using the guise of the leader's former android "son" Prince (attempted to be used by Silva as a bargaining chip) in hopes of trying to have a final chance to save his father.

Upon reaching the fortress, Doctor Man confronts Shuichi a final time, who pleads to try and save his father within the madman. Doctor Man appears to die still claiming he was the world's greatest genius; but the Anti-Bio Bomb rises up within Gear's main control computer to be disarmed within moments after Doctor Man's final explosion, making Shuichi believe perhaps some part of him was saved.
