What if Arturia had been summoned as a Berserker, with another Knight as Saber, in Fate/Zero? Something like this.
Rage. It was everywhere, turning the landscape of his mind into a burning inferno. Feeling his skin roasting by the flames, the intense heat making him start to pass out, Kariya focused on the one thing stark against the fire.
The Black Knight.
She looked at him with the full force of her anger, and she stalked through the fire as her Master stood up and was lifted into the air by a black gauntlet. The pain. So much pain, a storm of sorrow drenched emotion flooding his mind. No human could ever contain or comprehend so much; but he guessed a Servant had a larger capacity. She spoke to him, and he whimpered.
"I am the forgotten and despised. A failure in the history of war and bloodshed. My shining Kingdom raped by those who came after, its memory stained with betrayal. Birthed by the hopes and dreams of a a divided people, I am their corrupted martyr. And so I rage, I resent and hate. The fools who betrayed me lived and garnered their own unsullied glory. Because of his infidelity and their scorn, I am forever the whore of men!"
"But… the tales told…"
"FAKE! LIES! GLORIFIED SHIT! MY LEGEND IS WASHED CLEAN BECAUSE THE TRUTH DIRTIES THEM! I AM THE MARTYR FOR THEIR FALSE GLORY AND I SHALL BRING IT DOWN AROUND THEM! NO ONE WILL SURVIVE AND THAT PRETENTOUS TALE WILL END AS IT SHOULD HAVE DONE CENTURIES AGO!"
Berserker paused then, and tightened her grip.
"WEAK! COWARDLY! SELFISH! YOU ARE EVERYTHING I DESPISE IN MEN; YOUR SACRIFICE FUELLED BY YOUR LUST FOR A WOMAN! AS YOUR KING, I WILL USE YOUR BODY AND SOUL WITH HONOUR, FOR DEEDS GREATER THAN YOU DESERVE, UNTIL WE FALL INTO THE DEPTHS OF HELL TOGETHER!"
Oh god, he was really going to die.
Thanks for reading, please review!
