Flavius Metellus (c. 90s BCE – 47 BCE), also known as The Lion, was the Roman proconsul of the province of Kyrenaika. He was also a leader of the Order of the Ancients during the reign of Cleopatra and a close ally of Julius Caesar.
Flavius was born in the Roman Republic to an old patrician family which had lost much of its wealth. He was later married to an unknown woman who he had a son with. Flavius later married another woman named Porcia Orestilla, which helped to restore his family's treasuries.
Flavius later rose through the ranks of the Roman army and became a close ally to Julius Caesar. Due to his distinguished military career, he was later selected to become the proconsul of Cyrenaica, a position he held until his death.
Quest for the vault
- "The Snake takes that as your answer."
- ―Flavius, moments before killing Khemu
They had their soldiers capture Chenzira, a friend of Bayek's son Khemu, and convinced the boy and his mother Rebecca that they only wished to speak with the Medjay. Chenzira led the soldiers to Halma Point, where Bayek was defeated in combat and knocked unconscious, after which he was brought inside the Temple of Amun and before the Vault door. Flavius's fellow member Medunamun showed Bayek the Apple, but the Medjay did not know how to unlock the vault door. Frustrated, Flavius kicked Bayek to the ground, but was calmed down by Pothinus.
Before the interrogation could continue, the Pharaoh Ptolemy XIII, who accompanied the Order to Siwa, came to investigate. Flavius and some of the other members went to distract the Pharaoh. Khemu managed to steal a knife for Bayek, allowing the Medjay to cut free his bindings. Returning, Flavius then brandished a sword at Khemu, threatening to cut the boy's heart out if Bayek would not tell them how to open the vault. Bayek then broke free of his restraints, and a scuffle broke out between him and the Order.
Bayek pinned Flavius, holding the knife to Flavius's throat. The Roman simply sneered, taking Bayek's assault as his answer, and deflected the blade away. The blade instead struck Khemu in the chest, killing the boy instantly. A grief-stricken Bayek attempted to attack Flavius, but the latter used the Apple to knock the Medjay out. Flavius and the rest of the Order then fled the scene, leaving the Medjay for dead. Unbeknownst to Flavius, Bayek had in fact survived and began hunting down all involved in his son's death a year later. He later learned of the Order's existence and thus allied with Cleopatra to track down and assassinate every member of it.
Alexandrian Civil War
In 47 BCE, Flavius accompanied Caesar during his pursue of his son-in-law Pompey. Arriving in Alexandria, they were greeted by Ptolemy XIII, who presented the head of Pompey to Caesar, in hopes of gaining an alliance. During their meeting however, they were interrupted by the arrival of Aya, Bayek and Apollodorus, who carried Cleopatra into the palace within a rug. When Ptolemy demanded his guards to eliminate them, Flavius clashed with the guard but stood down at Caesar's command. Caesar demanded an audience with Cleopatra alone, ordering Flavius and Cleopatra's followers to leave the building. 
Later on Flavius entered and reported to Caesar that Lucius Septimius, the Gabiniani, and Ptolemy's forces had attacked the Roman legions. After the battle, Flavius used his considerable political power to have his fellow Order member Septimius spared from judgement and even offered Septimius a position next to Caesar himself, an act which greatly enraged Bayek and Aya. While the city celebrated Caesar's success, Flavius and Septimius broke into the Tomb of Alexander the Great to retrieve his staff, but were encountered by Apollodorus who had begun to suspect Caesar and Cleopatra and their actions and intentions. They managed to wound him and steal the Apple from him, after which Flavius and Septimius headed back to Siwa to finish what they had started two years ago.
After leaving the chamber, Flavius marched to Cyrene, where he had been appointed proconsul. Bayek had tracked him down to the city, and they clashed inside the Roman Akropolis. Despite Flavius' use of the Apple, Bayek was able to defeat him, and thus finally avenged Khemu's death.
Equipment and Skills
When in control of the Oracle's Relic, Flavius displayed a number of miraculous abilities. He was shown to possess the power to control the wills of the people and make them do things they would never do such as make them walk into a fire, force them to willingly allow themselves to be eaten by a lion, write his name on walls, dance themselves to death, murder each other, recite love poems devoted to him, make women leave their familes and proclaim their love for him, turn them into rapists and recite Order of Ancients propoganda. He was also able to create tangible-holograms of his former brothers which attacked Bayek. He could also turn invisible, project golden energy and fire a kinetic blast which slowed down Bayek momentarily. He was also a skilled swordsman and hand-to-hand combatant.
He was a strong political leader and mastermind, having become the leader of the Order of the Ancients. He was also able to use his influence to convince Caesar to spare Septimius despite the fact that Septimius attacked Roman forces.
