Gaios Anzem

Gaios Anzem (ガイオス・アンゼム) is one of the Seven Demon Elders created by Anos Voldigoad.

Appearance
Gaios is a huge man with twice the average person's height, dark skin, thick arms, and legs knotted with muscles. He also sports a beard.

Personality
Like his fellow Demon Elders, he is nothing but absolutely devoted to his creator and master, the Demon King of Tyranny.

History
Two thousand years ago, Anos created the Seven Demon Elders from his own blood, including Gaios. After Anos's sacrifice, the seven co-operated with the Hero Kanon to create the fictional Demon King Avos Dilhevia as a decoy to protect Anos when he reincarnated. Kanon then fused six of his sources with six out of the seven demon elders, including Gaios. He also erased their memories so Anos wouldn't discover their plan, as the Elders could not lie to Anos.

Demon Sword Tournament Arc
As part of the Great Demon Sword Training, Gaios and Ydol personally appeared to instruct Class 1-2. Because Anos is the only one that was able to pull out a demon sword, Gaios decides to spar with him. However, it quickly becomes a two-on-two fight due to Anos' cockiness: Gaios vs. Anos and Ydol vs. Lay. Gaios is effortlessly beaten by Anos and declares his loss.

After Anos defeats Lay during the finals of the Demon Sword Tournament, Melheis Boran ambushes the injured Anos with Gaios and Ydol. However, Lay is revealed to be still alive and beheads both Gaios and Ydol, while Anos stops time on their bodies in order to resurrect later.

Upon defeating Melheis and destroying the device that was controlling him, Anos attempts to extract the two unknown sources inside Gaios and Ydol for questioning, but an unknown masked person destroys them. Melheis then revives both of them.

Hero Academy Arc
When Avos Dilhevia returns and declares war on Azesion, Gaios is among the four Demon Elders who are on Anos' side. They follow him to Eiyan Hill, where Avos' army had built demon king castles to serve as their headquarters. While Anos heads towards the main castle, Gaios, and the others stay to fight the three Demon Elders who sided with Avos.

When everything was over, Anos teleported everyone back home.
