The Mummy Trilogy
Rick O'Connell is the reincarnation of one of the Ancient Egyptian MedjaiEverybody's already thinking it, I'm just saying it. We already know that he's one thanks to the tattoo on his wrist, and that Evy is the reincarnation of Pharaoh Seti I's daughter Nefetiri. It would make an incredible amount of sense for Rick to be a reincarnated Medjai charged with the task of protecting Nefetiri, and/or her lover.
The movie The Mummy (1932) was an adaptation based on Evy O'Connell's first novelThis was Universal Pictures, already known to have adapted Dracula and Frankenstein to film. Adapting Evy's novel for their Mummy movie makes complete sense!
Some Tomb of the Dragon Emperor fanon:
The series takes place in an alternate history:Nearly everything that the films pass off as fact about Egypt or China seems to be in there for the sole purpose of making learned people cry. This Troper was writhing on the floor in pain upon hearing that bit about an Egyptian New Year. Also, why don't they just use Qin Shi Huangdi's name? I saw no reason for the Emperor's name to be witheld.
The Medjai are immortal:They're in charge of keeping the world safe from Imhotep, if he was brought back from the dead. So, in order to make things right, they become immortal in-order to protect the world and it wears off when Imhotep has risen.
The Mummy films and Van Helsing are in the same universeMummies were not represented in Van Helsing, but they have a common studio and director (except for the third Mummy film). Van Helsing's organization isn't in touch with the Medjai because they keep to themselves and Imhotep was the first mummy to wake up ever. (This does lead to All Myths Are True.)
