The fully composed Gunbuster stands at 240 meters tall, taking a mecha-humanoid appearance. Gunbuster's torso and head transforms from Buster Machine 1, containing large, hulking shoulders lined with thrusters for heightened agility and movement. Large cylindrical arms fall from Gunbuster's shoulders. Buster Colliders are encased within both of the arms. Gunbuster's head takes the form similar to that of a samurai's Kabuto helm, adorned with a golden, gleaming crest representing the logo of the Imperial Space Force. Within the head lies Gunbuster's "Eye", a purple sphere with a single, powerful photon lens in the middle, which can emit a Buster Beam when activated. Gunbuster's lower body transforms from Buster Machine 2. From the hips descend large, cylindrical bipedal legs similar to that of Gunbuster's arms. Gunbuster's feet contain caterpillar treads tipped with serrated spikes. The legs can preform the Super Lighting Kick when activated. The whole of Gunbuster's body is colored dark gray with yellow-orange trim.
