During Sanmi Ittai, GunDober becomes the right arm of Big Volfogg, its exhaust pipes forming the 4000 Magnum. When Big Volfogg performs Chou Bunshin Sappou, its silhouette takes the form of a big cat; its head design in FINAL reflects this. GunDober acts on direct commands and does not contain a Super-AI (although during the fight against EI-27, it can be seen looking up towards Volfogg, as though to ask for him to hurry).
