The Séance

Klaus Hargreeves, known by the codename The Séance and designated 00.04 within the Umbrella Academy, is one of seven extraordinary children adopted by the enigmatic Sir Reginald Hargreeves to form the world's most unconventional superhero team. Born with the innate ability to commune with the dead, Klaus can channel spirits, levitate, and bend objects with his mind — a volatile cocktail of powers that mirrors the chaos of his personal life. His connection to the supernatural makes him both the team's most unpredictable asset and its most emotionally fragile member.

The Séance made his first appearance in The Umbrella Academy: Pantheon City / Zero Killer #1 in 2007, a Free Comic Book Day promotional issue that served as an early preview of Gerard Way and Gabriel Bá's landmark Dark Horse series. This debut issue is a prized find for collectors, representing the ground-floor introduction to the entire Umbrella Academy cast before the world knew just how significant the property would become. His full story unfolds across the main miniseries beginning with The Umbrella Academy: Apocalypse Suite #1 later that same year, where Klaus's reckless lifestyle and fraught relationship with his abilities are front and center.

Across subsequent story arcs including Dallas and Hotel Oblivion, Klaus continues to evolve in unexpected ways. His powers deepen in scope and consequence, and his sardonic humor masks a genuine vulnerability that resonates strongly with readers. The revelation of his immortality and the full extent of his necromantic abilities add mythic weight to a character who initially appears to be comic relief. Gabriel Bá's kinetic artwork gives Klaus a visual identity that is instantly iconic — disheveled, otherworldly, and impossible to ignore.

For collectors, Klaus Hargreeves books carry real heat. The Netflix adaptation of The Umbrella Academy brought a massive surge of interest in the source material, driving back-issue demand through the roof — especially for early printings of Apocalypse Suite #1 and the rare FCBD preview issue. High-grade copies of these key books are increasingly difficult to track down, and as the comic's cultural footprint continues to grow, The Séance's first appearances represent some of the most compelling modern-era collectibles in the Dark Horse catalog.
