Pharaoh Akhenamkhanen is a character in the Yu-Gi-Oh! manga. He is the father of Pharaoh Atem and the first holder of the Millennium Puzzle. This is the original version of Akhenamkhanen, known as Aknamkanon in the English anime.
In Ancient Egypt, Akhenamkhanen was the previous Pharaoh with Siamun Muran and Akhenaden as advisers. He loved his country dearly and was (most likely) oblivious that his brother was secretly resentful and felt relatively unimportant. When Egypt was under attack, Akhenaden pushed to fight back and protect their people, but Akhenamkanen refused on the grounds as he wanted peace. Eventually, the invading armies grew too close to the palace to be repelled, and Akhenaden suggested using a spell from the Millennium Tome to create the Millennium Items. Faced with the undeniable fact his kingdom may be destroyed, the Pharaoh agreed.
What Akhenamkhanen didn't know was that Akhenaden led a group of soldiers to the village of Kul Elna, where he ordered the thieves there killed, and their blood collected for the ritual to create the items, unknowingly leaving one survivor of this slaughter. The slaughter was so horrific that Akhenaden never told Akhenamkanen of it, and had all the soldiers he had taken brainwashed so as to forget the incident. Upon the invading army's attack a week later, Akhenamkanen, along with Siamun, Akhenaden, and four other priests used the Millennium Items to defeat the army.
Sometime later, Aknamkanon finds out about the massacre from Priest Mahado, who learned the secret from the Millennium Ring, he sacrifices himself to the gods of Egypt as a penance in a state of guilt and shame believing that it was his own choice of option for allowing this to occur, asking only for his son's safety from their wrath in return. After the disturbing discovery, Akhenamkhanen grew ill and died.
Years later, Thief King Bakura carries Akhenamkhanen's sarcophagus in front of Pharaoh Atem (Akhenamkhanen's son) and his Guardians and places the blames on the late Akhenamkhanen for killing his villagers to make the Millennium Items (although it was actually Akhenaden that was responsible). Akhenamkhanen (through his corpse) speaks with Atem with the instructions "Justice is in the name of the Gods" or "Justice lies with the Egyptian gods". Later, Akhenamkhanen's spirit again tells Atem the instructions "Justice is in the name of the Gods" is the key to defeating Zorc Necrophades. After the Ceremonial Battle, Akhenamkhanen is seen waiting for his son as he passes into the door between life and death along with the other guardians.
