True Identity

Berserker's real identity is Lancelot of the Lake, as revealed in the final volume of the Fate/Zero. Until his identity was revealed, he was known simply as the Black Knight.

Lancelot, known as the Knight of the Lake, had been loyal to Arturia as a Knight of the Round Table. He was one of the few individuals that Arturia viewed as a friend, and as such was privy to the secret of her true gender, as well as the nature and properties of her sword. Lancelot's downfall began when he fell in love with Arturia's queen, Guinevere. Though the king was actually a woman, Arturia had married in order to maintain the image of a stable royal family before the kingdom, and also to maintain the pretence that she was a male. Guinevere, in turn, willingly sacrificed her own life as a woman in order to preserve this ideal government.

When Lancelot and the queen began their affair, the Knight of the Lake considered fleeing Camelot with her, but his loyalty to Arturia and his sense of duty prevented him from doing so. When political enemies of the king exposed the affair, the queen was ordered to be executed. Left with little choice, Lancelot attempted to save her, killing several of his fellow knights in the process. Lancelot, who was considered the Perfect Knight, Guinevere, the queen who had made her beloved betray his duty, and Arturia the king who blamed herself for her loyal knight's despair, all suffered from the resulting fallout.

Lancelot's guilt was, ironically, compounded by Arturia's refusal to actually blame or reprimand him for his actions. He would later admit that this made him feel it impossible to atone for his sins. In his despair, Lancelot sought escape through descent into madness; thus, when he became a Heroic Spirit, he was summoned as the insane Berserker.
