Zegion

Zegion (ゼギオン) is an Insectar that was 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. After undergoing Rimuru’s Harvest Festival ritual the Magisteel given to him by Rimuru that had previously evolved into Adamantite has evolved into Scarletite.

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.

Background
Found near death by Rimuru near a dead blade tiger along with Apito. Sensing Rimuru coming to him and Apito, he attacked Rimuru recklessly, to serve as bait while Apito fleeing away only to be stopped by Apito herself when she asked for Rimuru's protection due to her recognizing Rimuru's strength and his intention to help them. Due to his injuries, Rimuru patched him up with his own slime body to aid the healing process and replaced his missing exoskeleton parts with processed magisteel. Later, he was named and tasked to guard the treants' settlement by Rimuru.
