Personality
Since Childhood, Mahad has and is a loyal person to people he cares about such as Atem and Mana, his apprentice. He often acts as a guardian for the two and deeply cares for them as evident when a snake was going to bite Atem, Mahad took the blow instead. Mahad is very selfless as he puts the well-being of others before himself such as when he ensured a child that he will protect the people. Mahad's greatest trait is his loyalty to his Pharaoh and childhood friend, Atem. Even though Mahad died in his battle against the Thief king, Mahad's loyalty to the Pharaoh is so great that even in death he was still willing to fight to with him as the "Dark Magician" and loyally continued to do so up until the end of the final arc.

Relationships
Pharaoh Atem

Arguably, his strongest friendship was with his Pharoah as they were childhood friends. As children, Mahad was the oldest of the children and had to look after both Atem and Mana. When a young Atem, Mana, and himself was playing in the garden, a snake appeared and was about to bite Atem. Mahad choose to take the hit instead and Atem decided to help him even though Mahad asked why he would do that to which the young prince reminded him that he is his friend. This event would shaped Mahad into the loyal person he is known for in his later years as a priest.Years later after Thief King Bakura's attack on the Royal Palace, Mahad decided to confront the Thief King himself and after an arduous battle Mahad decided to sacrifice himself to defeat the Thief King which ended up with him turning into a tablet and becoming Dark Magician. Before his final end came his last words to his king were "Pharaoh, I will always be your loyal servant." Despite his physical death, he lived on as Dark Magician and as the Dark Magician continued to fight alongside the pharaoh until the end of the final arc. In the Ceremonial Battle, when Atem summoned Dark Magician, Mahad told the Pharoah that even though he is a spirit, he will loyally fight with him showcasing the bonds between the two despite time has passed. This vow became the reason why the Dark Magician in the current era will always protect Yugi.

Mana

Mana is the childhood friend of Mahad and Atem. Years later when Mahad became a priest, Mana became his apprentice in the magical arts. Mahad himself can get tired of Mana whenever she appears such as hugging the Pharaoh surprisingly. Mahad as her teacher would often try to tell her to study her magical arts as well as ask if she did practice any spells. Mana also cares greatly for her master as when he died to sacrifice himself to stop Bakura, she was grief-stricken and morned for her master's passing. This event would shape Mana into becoming a great sorcerer like her Master before her and in the end it proved fortuitous as years later durning Priest and now Pharaoh Seto's reign she became one of the newly formed six priests as well as becoming the new owner of the millennium ring.

Priestess Isis

Mahad seems to care about his fellow priest's well-being. It seems that Isis seemed to have romantic feelings for Mahad as she was in tears, when he was going to die and later mourned for his death.

Priest Seto

There seemed to be little interaction between the two priests. Despite this, there was some instances of interaction but there relationship was not really a good one. This was evident when Mahad told the Pharoah that he and his magicians set up a barrier during the defense against Thief king Bakura, Priest Seto made a mocking statement about how good his magicians are which offended Mahad but Solomon one of the priests cut them off before a confrontation. Even though Mahad died honorably, Seto believed that his death changed nothing and that he was a fool for doing so which showed the negative relationship Seto had with Mahad.
