Don't be fooled by her beauty. Agrippina is a ruthless and cold monster. She manipulated events to put Nero on the Imperial throne of Rome and is the cause behind Nero's migraines.
Agrippina is evil to to the core. A fact that is not in the history books is that Agrippina, while pregnant of Nero, did a dark ritual. She gave her daughter as a vessel to an dark entity called Beast VI/S. She thought that, by doing that, she will gain control of the Beast and gain tremendous power.
However, it backfired on her and Nero, upon learning the truth, ordered the assassination of Agrippina.
She got reborned at the same time as Nero.Now, she have two goals.
1. Get revenge on Nero who betrayed her. She intend to rip the essence of Beast VI/S out of her daughter's body and bond with it, becoming the Beast of Humanity's new vessel
2. Acquiring the Holy Grail to fully become the Beast VI/S and gain its powers. In turn, it will cause the End of Times. And she already elected 4 of the most vile creatures ever imagine by Humanity to be her Riders of the Apocalypse.
One of them is a creature who couldn't stand his broken heart and decided to rip it of his own chest, turning into an hideous beast of the sea, cruel and unforgiving.
The other is a creature who do not seek world domination, it seeks to corrupt the world and bind it to its will by the flames of destructions, making the world at his image
The third one is a being devoid of love. Cold, ruthless. He wasn't corrupted by a dark master, he corrupted himself, alone. A self-made monster. Scared of his own mortality so much he mutilated his soul. He thinking defeating death would make him superior to anyone else, feeding his own ego.
The final one is the closest to the Biblical Satan one could be. The seductive face of evil. Promising greatness and power, but only giving pain and suffering and turning people into disposable pets. Patiently waiting on his throne, waiting for the next soul to corrupt and make his to do as he pleases.
Vile creatures for a vile woman.
___
- Driven to Madness: It is stated in "[Ai Art] Goliath - Fate/Grand Order OC" that she has been hearing drums in her head for as long as she can remember, and that this is what has driven her crazy. It is also implied that it is the Master (who lived with her as Caligula) who is the cause, and The Toymaker confirm finally it.
- Evil Matriarch: An obvious one since she poisoned Nero.
- Hair of Gold, Heart of Gold: Subverted. Her heart is as black as her hair is golden.
