Trihexa (666), also known for many names in her timeline, such as The Beast Of Apocalypse, The Goddess Of War, The Queen Of Destruction, Anti-Christ, Dragon Of Darkness etc.

She is considered the second most powerful thing that exists in the universe due to her unreal strength who's almost as strong as the God of the bible. Many are not sure what to classify her, if she's a fallen angel or a devil. But one thing that they knew is that she's not a creature to be underestimated…

But she wasn't always like this, she was a former general of heaven as her name wasn't always Trihexa or her current titles…

Artoria Morningstar (Pendragon) also was named Saber at the time. She is known for being the perfect angel alongside his brother Lucifer Morningstar and both of them were called the Twins Of Perfection and Lucifer at the time was the heir apparent of Micheal . She was at first a warrior of the angelic army and the apprentice of the archangel Gabriel. She was a prodigy and she had a lot of loyalty towards God of the bible. While Lucifer was a prideful angel since he was considered perfect, she was the opposite.

She was kind and gentle, she never saw herself as superior or the most powerful. She treated the other angels as equals unlike her brother who always saw himself as superior. And she always scolded her brother for him to change his ways before God, who they called father, gets furious against him. But leaving that detail to the side. She was the strongest member of the army as she was respected in the battlefield as she one time was able to kill 100 million fallen angels by herself with zero damage.

But there was a change of events that happened in heaven. So Lucifer started a cult behind the scenes and the number of the angels in that cult was around 1 million angels and they planned to raid heaven and kill God so that Lucifer could be the next God of the bible, but Saber refused to let him kill their father as she had a brutal fight against her brother as she felt betrayed by her own family, but it wasn't the time for her to cry about it. At the moment of the fight, they weren't siblings, they were enemies and she was the soldier of God, so she had to be strong for her father…

Eventually God found out about the raid that Lucifer planned on doing with his cult. He was furious that Lucifer would do this after all the blessings that he had. So instead of making him a fallen angel, he decided to make him something even worse…and that's how devil's were born. He became a devil alongside his cult and they were banished from heaven for eternity. Despite all the trouble that her brother has caused, she still cared about him and that broke her heart seeing her brother like that and she silently cried for him, but she had to be strong for the sake of God and for the rest of the angels. God then put all of his attention to Saber as God acknowledged her strong loyalty for him as he decided to upgrade her status and make her something beyond what she was before.

She was now called Lancer, and she became an archangel with 12 wings, the strongest angel of all at that time, even 10x stronger than the other archangels and the official general of the army of the angels. She still continued being humble and kind hearted towards her comrades. But there was a lot more pressure for her since she was the general as she was also in charge of training the rookies. Although it was tiresome, she was satisfied that she could be as useful as she could. Even though she was kind, she was very strict and serious when it came to being a warrior. Everything was going smooth for a few 100 years, till, one event that changed everything…

It was informed that Lucifer wanted to raid heaven again as he returned filled with a lot of hatred and rage against everyone in heaven alongside with his army of devils and the number of them was more than 10 million devils ready for blood and the angels were aware about the second raid attempt. So they were training twice harder than before and Lancer was training herself to face her brother for the second time. She didn't know how strong he got so she couldn't underestimate him.

It was now the day of the battle between angels and devils. The angels and the other archangels were ready for the battle which took place on an alternative dimension so that the devil wouldn't sneak out of the battlefield. Lucifer had a golden armor (he basically looked as identical as Gilgamesh archer) and he had his former face again as he was ready to kill his sister and take over heaven…

The battle that they had was bloody as both sides lost a lot of soldiers who either passed away or were critically injured, but they were extremely tired as they had been battling for 3 days straight. So the only ones who were standing were Lancer and Lucifer. Lucifer was the one with more damage than his sister as Lancer had a broken helmet and the chest armor had cracks and she had some cuts. Lucifer had his whole armor broken and he had severe injuries and he lost an arm and an eye.

He was going to lose and when they tried to attack each other again, Lancer just cut his other arm and cut his stomach so his internal organs could be seen and he was bleeding and he was slowly dying.

Before Lancer could do her finishing move, Lucifer chanted a curse which in that curse, he would transfer all of his demonic powers and energy to her as her angelic traits got corrupted and she lost her wings and her sanity. So both the armies were confused on what was happening since they saw light being switching colors from bright to dark as she yells in pain and then she roars like a devil with a mix of a dragon in the process. After the beam disappeared, the armies tried to look closely to see what was happening. But they all saw Saber again, but…she looked different as she was covered in dark aura and her armor turned black and her hair turned into a whitish blonde, her eyes were covered and her skin was pale

Before they could figure it out, she sadistically grins as she releases a dark aura explosion, which killed everyone on sight on how dark and intoxicating the aura was. When she saw dead corpses and how the dimension was broken and at the collapse of breaking down she laughed at it like a psychopath, she thought that it was amusing seeing them all deceased as they died miserably. But then got confused on why was she feeling happy about their death when she never had remorse or grudge against them, but she grins in response to her thoughts as she thought it was pathetic as she embraced the dark side

So, basically then after not much time as passed, heaven heard the news regarding Lancer, which she returned to her Saber form, but she was anti than them and they couldn't tell if she turned into a devil or a fallen angel as she didn't possessed wings, and they told God about it.

He felt like a failure and sad about the situation as God couldn't reverse the transformation, even if he was God, he had limitations as God knew what Lancer has become, and he felt fear, not because could be able to kill him, but she has surpassed every being when it came to power scale as her personality changed and now she wants destruction of everything in existence…

Eventually Saber returned to her Lancer form, but she was still corrupted and she got more powerful than before. She started terrorizing hell, the devils and fallen angels as she killed them mercilessly, she even went after the Greek mythology and other mythologies as she was terrorizing, she spared the Gods, because she thought it would be boring if she took their lives.

She eventually started calling herself Trihexa due to her curse as she has a 666 mark on her neck. She eventually got other titles from bunch of folklore and stories. She even started destroying a few cities on planet earth, and one of those places were Egipt and Canaan. The same cities that the Hebrews were initially at, ever since Moses came in the picture. But she attacked it when Moses was already dead as well as Joshua.

And then sometime passed as she then felt something was going to happen in Jerusalem. And the event was that Jesus Christ, the son of God was about to being given birth, and she was it was an opportunity to attack the town and kill him as she was power hungry and bloodthirsty. So she ran towards the two with her horse as she feeling adrenaline and excitement to the son of God himself.

It was already midnight when Jesus was born as she rushed and rushed to get him and take his life and shower on his human parent's blood. While she was rushing, the sky got bright as she was a legion of angels surrounding her and refusing her to pass through. But that didn't discourage her as she thought it was a good moment to stretch herself, and she could feel that the angels were twice stronger since God gave them their blessing just to stop her and she thought it was pathetic but she didn't want to refuse the fight.

So she then started fighting against the angels by herself as she was killing a lot of them even with the blessings that God gave them. While they were fighting, a few men were hiding, watching and observing the fighting as they were amazed and terrified as they never saw something like this happening.

While she was fighting the angels and she was clearly winning, Micheal appeared at her presence as he showed his 12 wings and he had a serious look on his face. He was heartbroken how on how she has become. So right now Trihexa was looking at Micheal with murder on her mind as she had a sadistic look on her face and Michael then lifted his sword up as a light beam hit the area that Trihexa was and she throught that it was nothing, but the she started feeling something tying her up as she tried to free herself, but it wasn't working and the a light explosion happened and the angels, Trihexa and Michael disappeared and the men that were watching got out of their hiding spot as they were terrified and amazed on what just happened.

So now in heaven,. Michael went to notify that Trihexa has been successfully captured and seal and God felt relieved that everything was now resolved. But where Trihexa was sealed, she hands pierced on the wall by nails as she was tied with golden chains and her legs were also tied. Her sword was nowhere to be seen and she didn't have her armor and she only had clothes that supported the armor. But she wasn't fazed or angry about it as she was actually more eager to destroy everything

'It doesn't matter how long I'll be sealed…it can be for months, years, centuries or even millennials…I'll always come back to take everything from you…'

And cut.
