Mahad, known as Mahado (マハード Mahādo) in the Japanese version, is one of the priests who serves Pharaoh Atem. He wields the Millennium Ring. In an attempt to defeat Thief King Bakura, he sacrificed his life and fused his Ba (Life Spirit) and his Ka together to create the "Dark Magician". He also was the best friend of the Pharaoh Atem since they were children. Before and after his death, Mahado always kept loyalty to his king. Mahado is the first among the six to die. He continued to serve the Pharaoh in the form of the Dark Magician. He also appeared in the Battle Ritual, Summoned by Atem in his Duel against Yugi Muto.
Mahado is very loyal to his childhood friend and Pharaoh, Atem, and is also Mana's teacher in the magical arts. He acts as a guardian for both Mana and Atem and cares deeply for them both. He also seems to have a close friendship with Isis. Mahado is very selfless, looking out for the well being of others before his own. His loyalty runs deep and he serves Atem with a strong conviction.
The name Mahad is a male Muslim name from Arabic origins, meaning: "one who is great". His Japanese name, "Mahado", can likely be translated to "magical wave", hinting his use in Spellcaster monsters such as "Illusion Magician".
As a child, during the time when Aknamkanon was Pharaoh, he, Atem, and Mana were good friends. He had to guard and protect the prince. At one point, he got bitten by a snake, and Atem saved him by sucking the venom out.
As a Priest
He later became a High Priest serving Pharaoh Aknamkanon. Mana became his apprentice. Also, he acquired the Millennium Ring and told the Pharaoh of the Kul Elna massacre. During an unspecified point of time, he had sealed his great power in a tomb. After Aknamkanon died, Atem became Pharaoh.
Mahad fought Thief King Bakura when he raided the palace alongside Atem and the other priests. Bakura later fled when Atem summoned "Obelisk the Tormentor". He later led Bakura to the Valley of the Kings. He and Bakura entered a tomb, where he had sealed his power, and his men blocked off the entrance so that Bakura can't flee. However, during the fight, despite obtaining the great power, he sacrificed himself to fuse his ka and ba together to form "Dark Magician" after he was severely weakened. He then made a blast so powerful that Bakura was believed to have died. He continued to serve Atem as the Dark Magician, and even destroyed Bakura's Diabound during their fight at Kul Elna. He participated in the final battle aganist Zorc Necrophades, when the latter began his assault on the palace. He and the Dark Magician Girl, Mana's ka, attempted to destroy Zorc with a combined attack but Zorc was unaffected and easily wiped them out. Mahad's soul was among others waiting for Atem in the afterlife.
