This article, Xander Ambrosius, is the sole property of DevilSlayer, also known as HolyknightX, so be warned before begin to edit.

Why I joined the Khaos Brigade, you ask? ...You see my answer is simple, I just despise human beings...I always have and I always will. They're too easily corruptible, they're weak minded and frail creatures. Devils are just annoying beings who rely only on their status and strength. Angels are simpleminded beings who're lost without their creator. Fallen Angel are just filthy and pathetic crows who lost their way. And then there are the Gods who just sits by and won't strike fear into any of them, that's why I create a new one. So just die and save me the trouble, because it's only going to be a one sided genocide.

Xander Ambrosius is one of the major antagonists in The Magic Knight. He is the father of Galahad Du Lac and Christian Ambrosius, Xander is also the ex-husband of Elaine Du Lac. He is the former leader of the Ambrosius Family, before defecting to the Khaos Brigade, more specifically Qlippoth. Xander is known as the 'Strongest Magician'.


Despite his elderly age, Xander has the appearance of a young man with silver hair and red eyes, it is unknown how he was able to retain his young appearance. He is normally seen wearing royal Magician robes that signifies his status as the highest grade of Magician. Most of the time, Xander has a sadistic smile on his face that usually sends shivers by the spines of those around him.


Xander acts in a sadistic and cruel manner towards those around him, speaking down to even the members of his family and even to his own allies. He also only sees those around him as nothing more than pieces that are placed on a boardgame and states that the lives of any and all lower beings are nothing more than an annoyance to him. In the past he has acted cruelly towards his two children, most of the time he drugs them and place them in a dangerous situation after waking up.

His cruelty even goes to commencing heinous experiments on orphaned children and people, that he state goes beyond even the Holy Sword Project. Also according to Xander, he despises human, even the factions in the world; that includes Angels, Devils, Fallen Angels and even the Gods. He even states that he desires to completely eradicate every single one of them completely, which was the reason why he joined the Khaos Brigade.

Going as far as to murder his own parents without even the slightest bit of hesitation to prove himself. Xander believes that a peaceful life is a boring life for a Magicians and a Mad Scientist like himself, so he seeks a world full of chaos. Aside from despises humans and other races, Xander like Evil Dragons more, since they are more honest and aren't afraid to do what they wish.


Xander is the only child of the former leader of the Ambrosius Family and his wife. As a child, Xander was viewed as a child prodigy and was exceedingly bright possibly surpassing the knowledge of most adult Master Magicians and being able to understand the world and everything in it. Like Christian, he was always reserved, though unlike him he showed no sign of compassion towards his family and secretly finding them to be annoying and a hindrance.

During his studying he began to dig deeper into the realm of forbidden magic and began to experiment on living creatures in utter secret, making sure that no one from the Ambrosius Family or the Magician Organization would find out. When he was in his late teens, he was approached by Rizevim Livan Lucifer and told him his plans involving Ophis, the Holy Grail and even 666 (Trihexa) and about the other world that Rizevim mentioned in their conversation. After hearing about the other world, Xander felt elated that there was another world that was different from the 'dull' world that he lived in.

But before he could join up with him, Xander had to prove his loyalty by killing his own parents in secret and becoming the leader of the family until it was right for him to officially join him. After Rizevim teased him about not having the gut to do it, Xander only laughed and responded, "Family? I've lived a dull life with a dull father and mother, if you didn't tell me to kill them...I would've done it myself." Afterwards he murdered both is parents without no one finding out it was him and later became leader of the family.

After becoming his families' leader he later met up with the heiress of the Du Lac family, Elaine and decided to pretend to care about her. Xander only saw the time that he spent with her as a theory that he wanted to prove...could a Knight be born with the capabilities of a Magician.
