Over October I made a bunch of Pokemon versions of some classic Characters from English Gothic Horror: Victor Frankenstein, Count Dracula, Jekyll and Hyde...
A little late to the party but I say let the Spooky Season Continue! Day of the Dead is in November, the days are getting darker and colder, and the Wild Hunt Persists through to the Winter Solstice hollering through the sky in pursuit of their spectral prey!

If Vampires are the Nobles of the Undead there is still one higher, The King...Tonight is for the Mummies! Theoretically almost any pokemon could be a Mummy, the Egyptians mummified thousands of Animals as well as Pharaohs and Nobles; From Cats and Dogs to Crocodiles, Baboons, Birds, etc...but I decided to bring back a familiar character. Ozymandias the Lucario.
Ozymandias' name comes from a poem which uses the the Greek version of Pharaoh Ramesses II, and Lucario is based on Anubis the God of Funerary Rites and Mummification, so it felt just too ideal to make a Lucario named after an Pharaoh the representative for the Mummy, albeit more along the rehydrated variety than the husk variety, but there is precedent to that in English Literature with there being many stories of Mummies coming back looking as they did before they died and having strong opinions about the future world they have woke up into. Ozymandias certainly has some strong opinions about this world.

(I also took some inspiration form:
Madara Uchiha - Naruto
Lord Pain - Naruto
Dio - Jojo's Bizarre Adventure
Kars - Jojo's Bizarre Adventure
Seto Kaiba - YuGiOh
and Demon King Ganondorf - The Legend of Zelda: Tears of the Kingdom)

Ozymandias was born to an era of seemingly endless Wars and Chaos between the Legendaries and Yaldabaoth the Usurper and his Dark Forces. In order to survive the onslaught of destruction you needed to be strong, but Ozymandias strove beyond just survival and strength, he fought to establish a land of security and order amongst the chaos and save as many pokemon as possible. By his own effort he became The King of Kings mighty and righteous ruling the greatest empire the world had yet seen, though it came at great personal cost to him including the life of his young daughter Princess Anapi who fell ill while he was away.

Ozymandias firmly believes Rulership should not belong to those who desire power, Rulership is a sacrafice that demands of the leader to constantly fight themself to be greater than themself, but this has lead him to sees the faults and impurities in everyone else around him, and believe that no one else is qualified to be incharge and that it's his duty to take charge and will lead people to overcome their earthly flaws whether they want it or not.

By the end of his life he was laid to rest in a great tomb alongside his daughter, becoming a mummy so he could rest but his spirit would inhabit his temple and offer his wisdom to his successors through the ages till he may rise again revitalized and immortal to lead the world again to a new prosperous age, But following his death Yaldabaoth was finally sealed by the Legendaries and his existance was erased from the memories of pokemon. While Ozymandias was remembered as a great king the context for his rule was lost, and so was part of his legacy, so he never got to pass on his Wisdom.

The world he woke up to, he was not very impressed with, he believes this current world is corrupt and weak, a problem he plans to rectify... An old Absol called Tezoca the Hierophant found him and offered him a role familiar to organization from his era which withstood time by the allowance of the Legendaries; The Major Arcana, a group founded as spies to undermine Yaldabaoth in his era, now they were guardians to protect the world from his return. Fittingly Ozymandias was given the Tarot card of "The Emperor" and he joined with other members in the Major Arcana becoming known as the 7 Heavenly Virtues, representing the Virtue: Chastity, not because he has specifically sworn off Sex specifically though is not particularly interested in anybody sexually...more like he values self discipline.
"Ones with this virtue are unhindered by worldly desires. They are able to overcome temptation and show self-discipline not through lack of being tempted, but rather of making the conscious decision to better yourself rather than do what you know is morally wrong."
However despite representing Virtues and their initial reputation as heroes they soon became feared! Ozymandias doesn't care though, he is determined to make a better world he rules regardless of what pokemon think of him.
