The ghost who walks among the living, haunted by addictions and the voices of the dead.
Klaus Hargreeves, known as Number Four, is the necromancer of The Umbrella Academy and perhaps its most tragic figure. While his powers make him a valuable asset in supernatural conflicts, his life has been defined by a desperate struggle against addiction and trauma.

Lore & Background
Despite his self-destructive tendencies, Klaus's powers are among the most potent in the universe. He can summon spirits to fight, bargain with them, or even temporarily inhabit their bodies. His relationship with death is unique; he has died multiple times throughout the series, often returning from the afterlife with new insights or scars. These experiences have forced him to confront his past traumas and eventually seek sobriety, transforming him from a liability into a crucial anchor for his family during apocalyptic crises.
In Their Own Story
The air in the alleyway smelled of wet cardboard and stale rain, but Klaus didn't mind. The spirits here were loud, screaming about lost wallets and unfinished business, their voices scratching at the back of his skull like static on a broken radio. He lit a cigarette with trembling hands, the flame illuminating the hollows under his eyes. 'Shh,' he whispered to the air, though no one living was there to hear him. A translucent figure in a tattered suit appeared beside him, weeping silently. Klaus took a drag, exhaled a plume of smoke that mingled with the ghost's form, and offered a weary smile. 'We'll get through this,' he lied, mostly for himself.
Reader's Guide
The universe of The Umbrella Academy operates on a metaphysical plane where death is not an end but a permeable membrane. Klaus's abilities reveal that spirits are bound to the physical world by strong emotional ties or unfinished business, allowing them to be summoned and manipulated. Historically, the adoption of the seven children was a calculated experiment by Reginald Hargreeves to create a defense force against an unknown threat. However, the psychological damage inflicted on Klaus suggests that the Academy's training methods ignored the spiritual toll of his specific power set, leading to decades of avoidance and addiction. The deeper rule governing Klaus is that sobriety acts as a catalyst for his true potential. When he is intoxicated, his connection to the spirit world is chaotic and uncontrolled; when sober, he achieves clarity, allowing him to navigate the afterlife with purpose. This dynamic emphasizes the series' theme that personal trauma must be faced directly rather than numbed away.
