Jed Altman, as an Otto warrior born of fusion setting, all his forms are fused by two different Otto capsules in the plot. For such a setting, it can be clearly affirmed that he has no ontological form. Follow-up with the appearance of the theatrical version, in this work, the appearance of G&D Altman polar form and the use of a single Otto capsule, in my cognition, think that the ultimate form is G&D Altman's ontological form. As for the reason, I will give you a detailed explanation.

In the TV version of the story, G&D Altman really appeared at the beginning through the fusion sublimator, using his father beria's capsule and the first generation Altman capsule. Since then, other morphological changes have been realized by using the strength of Otto's predecessors and other capsules. In the TV version, Emerald Altman really doesn't have its own ontology.

The appearance of the theater version of the ultimate form, from the appearance of the ultimate capsule, the previous Aote capsules are all from monsters or other humans, but the ultimate form capsule is different, a capsule appears from asakura Road itself. The birth of the ultimate form is also directly transformed with this capsule and the ultimate combat instrument. For this deformation mode, the ultimate fighting tool is G&D's Transformers, and the space capsule is the source of light energy. This conclusion makes me feel that the ultimate form is his ontological form.

In addition, in terms of body shape during transformation, in the TV version, before G&D Altman really integrates the strength of two Otto fighters, an illusory body shape will appear every time. Under this body shape, G&D Altman can gain the strength of two Otto fighters, thus becoming a powerful form. When the ultimate form was born, a careful look at the illusory figure that appeared during the TV merger can be said to be exactly the same as the ultimate form of G&D Altman. This is why I think the ultimate form is the ontological form of G&D Altman.
