Judar (ジュダル, Judaru) is one of the four Magi in the current era and a Magician who specializes in Ice Magic. He is the former Oracle of Al-Thamen and the Kou Empire after siding with Hakuryuu to aid him in taking over Kou Empire. According to Hakuryuu Ren, the name "Judar" was given by Al-Thamen, and his real name is unknown.
Judar is very powerful, cruel, arrogant, and somewhat childish. He's also shown to be rather spoiled since he has led a pampered life as a Magi. Usually, he doesn't listen to anyone's advice or orders and does things his own way. He is usually disrespectful, even to his fellow Magi. He seems to be careless about what others think, goading Sinbad into feeling pity for him and then laughing at him. He is a good actor and goes to great lengths to mock others. Because of his confidence in his abilities he enjoys fighting and war, declaring without support that the Kou Empire will destroy Sindria. Judar does not mind injuring and attacking innocent bystanders of his fights and civilians. Judar doesn't let his troublesome past bother him, as long as he gets to do whatever he pleases. However, he also seems to hold deep grudges as he couldn't forgive Al-Thamen or Gyokuen Ren for using his life for their own ends and asked why they couldn't have used Scheherazade or Yunan and why it had to be him.
During his time with Alibaba, he's shown to be very spoiled and complained a lot.
During Sinbad's first trial, Sinbad reveals Judar was having second thoughts about his life and involvement with Al-Thamen due to being under the influence of Solomon's Wisdom. Judar shakes it off and finds his current life already fulfilling.
