Amalthus

Prateor Amalthus, or simply Amalthus, is the main antagonist of Xenoblade Chronicles 2. He is Indoline Blade Eater that rules Indoline Prateorium as its Praetor. He is the current Driver of Fan la Norne and Minoth, and formerly Malos.

He is voiced by Corey Johnson in the English version, and voiced by Junichi Suwabe in the Japanese version.

Appearance
Although Amalthus appears to have a young appearance, he is actually a very old man, having lived before the events of the Aegis War. He has light blue skin, white hair and wears a royal outfit.

After absorbing all of the Core Crystals he's gathered, his general appearance has taken on more of a monstrous appearance, in addition to gaining red eyes and blue tentacles made out of energy.

Personality
Initially, Amalthus appears to be a calm and respectful man. He is very welcoming and caring for his guests, to the point that he allowed them to stay at his Sanctum.

However, in truth, Amalthus is a cold-hearted, psychopath that is hell bent on the destruction of humanity. Ever since the death of his mother, he has developed a motive of wiping out humanity from existence. He believes that it's the Architect's will of cleansing the world by destroying humanity. According to Pyra, Amalthus' hatred and anger is the main influence of Malos' destructive nature.

Despite this, he is not a complete monster. He still holds a heart for others. This is shown when he saved Zeke from near death for Pandoria's sake.

Prior Events
Many years ago, Amalthus and his mother were on the run from a group of men. His mother decided to get rid of him, by pushing him down a tree, in order for him to save his life. When Amalthus awoken from his fall, he stumbled around the forest, until he came across the men that killed his mother. Devastated at the sight of his mother's corpse, he grabbed a rock and proceeded to kill one of the men with it.

Since then, Amalthus has traveled around Alrest, assisting those in need and sharing his ideas. When he walked around in a forest, he came across a house where he discovered a soldier that he healed was ready to kill a woman and her child. Amalthus, however, prevented the man from doing so and instead killed him. He then took the baby with him, calming it down, and watched the skies, wondering what the Architect's true intentions were when creating the world.

Some time later, Amalthus traveled to the World Tree, where he managed to reach to Elysium. There, he came across the Aegis Core Crystals, which he ended up taking home with him. When he returned to his home, Amalthus grabbed the purple Core Crystal, which as a result, awoken Malos. Malos proceeded to destroy humanity, while Amalthus left the other Core Crystal for the time being.

Eventually, Amalthus passed down the Core Crystal to Addam, who unleashed it, awakening the Aegis Mythra. Together, they were able to defeat Malos in the Aegis War. After the war, Amalthus became Praetor of Indoline Praetorium and began to gather Core Crystals around the world. He would later use these Core Crystals to create Blade Eaters, by fusing them with children.

At some point, Amalthus came across Pandoria, who was grieving over the fact that Zeke was ready to die. Amalthus decided to split Pandoria's Core Crystal and place it in Zeke, making him a Blade Eater. Preventing him from death, Amalthus promoted Zeke as his special envoy and gave him the task to find the Aegis and its new Driver.
