Haunted Hotel Season 2 spoilers ahead.
Abaddon is one of the biggest reasons Haunted Hotel’s supernatural chaos works. The demon trapped in a young boy’s body can be terrifying, absurdly blunt, and unexpectedly sweet—sometimes in the same scene. Season 2 gives the character more room to show all three sides, which helps explain why reviewers are calling him a standout.
Why Abaddon stands out in Season 2
Abaddon’s central joke is also the source of his appeal: he speaks and thinks like an ancient, powerful demon, but he has to navigate ordinary family life and the hotel’s day-to-day problems. That contrast gives the writers a dependable comic engine without reducing him to a one-note gag. His deadpan confidence makes even small interactions feel like a supernatural threat—or a punchline waiting to happen.
Season 2 also places him more firmly inside the Undervale’s makeshift family. The show can play him as dangerous, but it can also let him behave like a kid who wants attention, approval, or a place to belong. Those shifts make the character more than a source of scary one-liners.
Jimmi Simpson’s performance makes the demon funny
Real-life actor Jimmi Simpson voices Abaddon. The performance relies on contrast: a composed, matter-of-fact delivery for lines that are anything but ordinary. That restraint helps the character’s threats land as comedy, while leaving room for moments when Abaddon’s attachment to the hotel’s residents feels sincere. TheWrap’s cast guide also identifies Simpson as Abaddon’s voice actor.
Fans and reviewers are responding to the character
There is a difference between saying Abaddon is a fan favorite and claiming a measured, platform-wide trend. A recent CGMagazine Season 2 review specifically highlights Jimmi Simpson’s Abaddon and Natalie Palamides’ Esther as characters who “steal the spotlight,” while Mama’s Geeky describes the character as a fan favorite and praises his one-liners in its Season 2 review. Those are identifiable reviews, not a formal audience poll.
The discussion threads give fans a place to compare favorite moments and reactions. Read the Season 2 Reddit discussion and the “Ghost Day Out” episode thread. Individual comments are anecdotes, so they should not be treated as proof that every viewer agrees.

Is Abaddon officially the breakout character?
“Breakout character” is an editorial description, not an official Netflix award or a measured ranking. What can be supported is that multiple reviews single him out, the Season 2 marketing brings him to the front, and his contrast of demonic menace with childlike behavior remains one of the series’ most distinctive ideas. That is a strong case for calling him a standout—without pretending that every fan or critic has the same favorite.
