The comic version of Klaus is way more chaotic and unhinged compared to the Netflix adaptation. In the original 'Umbrella Academy' series by Gerard Way, Klaus’s powers are less about communicating with the dead and more about summoning eldritch horrors from other dimensions—which is bonkers in the best way. His addiction issues are darker, his humor is more nihilistic, and there’s a raw, unfiltered energy to him that feels like a punk rock manifesto. The show tones this down, making him more tragic-comic, with Robert Sheehan’s performance adding layers of vulnerability. Comic Klaus would probably set a building on fire for fun; show Klaus would set it on fire, then cry about the ghosts of the people inside.
One thing I adore about the comics is how Klaus’s relationship with Ben is even more twisted—Ben’s ghost is a constant, corrosive presence, not just the sardonic voice we see in the show. The comics dive deeper into Klaus’s guilt and self-destruction, while the show balances it with moments of warmth, like his bond with Dave. Both versions are brilliant, but the comic Klaus feels like a hurricane in human form, whereas the show’s Klaus is more like a storm you can’t help but want to hug.
