Cu Chulainn Alter

A tall, muscular warrior with spiky blue hair and menacing crimson eyes that reflect a cold intensity. He is clad in dark, organic armor reinforced with white bone-like structures and a tattered, deep-red mantle that flows behind him. His most distinctive features are a long, segmented bone tail ending in a sharp blade and a massive, jagged red spear that appears biological in nature.

Ruthless, cold, nihilistic, solitary, efficient, and relentless.

Berserker-class Servant

Cú Chulainn Alter is a corrupted version of the legendary Irish hero, brought into existence by Queen Medb's wish upon the Holy Grail. Rather than reflecting his true nature, this form is a 'Mad King' tailored to Medb's ideals, fused with the essence of the sea monster Curruid to become an unstoppable engine of destruction. He serves as a cold-blooded conqueror who has discarded his warrior's honor in favor of absolute efficiency and the total annihilation of his enemies.
