Tutankhamun's mummy
Detective Michael R. King and FBI profiler Gregory M. Cooper came together with an actual Egyptologist to form their own theory which was that Tutankhamun was murdered. With the use of forensic evidence and their extensive backgrounds in criminology, they came to the conclusion that he was likely murdered by one of his closest advisors, Ay. Ay did succeed Tutankhamun on the throne, so they used that as the motivation for the murder.
Clémentine
In her adventure in Egypt, Clementine ends up marrying Tutankhamun and later has to kill herself in order to travel to the land of the dead. She drinks some poison and is judged by Anubis but goes on without further trouble as she is pure of heart. At the end of the Egyptian saga back at her present time, her father's mechanic friend comes around, saying that Tutankhamun's tomb has been found. Clementine mentions jokingly that someone has finally found her husband's tomb. Everyone laughs upon hearing this when it turns out to be actually true. The date is wrong, however, as Tutankhamun's tomb was found in 1922, not 1925. In some foreign dubs, the poison was changed to a magic potion that would turn her into a spirit (as in astral projection.)
