Zegion

Zegion (ゼギオン) is an insectar that has been found, rescued and subsequently named by Rimuru in the Great Jura Forest.

Original
During his debut, Zegion appeared to be an extremely large beetle with characteristics of both stag beetles and rhinoceros beetles.

Humanoid
Later he evolved into a humanoid form that looks like a warrior clad in pitch-black exoskeleton with visible golden joints. A red-tipped, sword-like horn protrudes from his forehead. The exoskeleton took the form of Rimuru's preference.

Personality
Zegion usually has a calm and serious demeanor, speaking very few words. However, he is fiercely loyal to Rimuru and any words he interpreted as an insult to Rimuru would quickly anger him.
