Right now there is no officially confirmed single “main villain” for Hazbin Hotel season 3, but the strongest canon-backed hint is that Alastor (the Radio Demon) will step into a much more outright villain role, with Lilith and other overlords still in the larger mix of antagonists.

Quick Scoop: What We Actually Know

  • The show’s creator has teased that a “friendly face” / anti‑hero type will become a villain in season 3 , describing a trickster character with hidden, more sinister motives.
  • In the same interview, that description is framed around a character fans widely recognize as Alastor , who has just regained his full power by the end of season 2 and is positioned as one of Hell’s strongest demons.
  • Official background info also notes that Lilith is a long‑term “slow burn mystery” who will have a notable presence in season 3, but she is framed more as a central puzzle and power player than clearly labelled “the” new villain.

So the safest answer: Alastor is heavily teased as the season 3 villain figure, but the show has not publicly locked in a single, definitive “big bad” yet.

Creator Teases vs. Fan Hype

The fun of this topic is that official teases and fan theories are blending together a bit.

What the creator tease implies

  • The tease describes:
    • A character seen as a friendly face or anti‑hero in seasons 1–2.
    • Someone who joins the heroes’ side at first, but in season 3 reveals darker motives and a more outright villain arc.
  • The interview then very directly pivots to Alastor , highlighting:
    • His restored powers after his deal is broken.
    • His ambiguous “care” for Charlie and whether that care is genuine or just another layer of manipulation.

That structure strongly pushes the idea that Alastor is being set up to be the primary villain figure or at least the most personal, emotionally loaded antagonist in season 3.

What fandom discussions are saying

Across forums and theory videos, fans are actively debating who fits the “anti‑hero turns villain” clue best:

  • Many fans argue Alastor is the only one who perfectly matches the description and the timing of the power‑up at the end of season 2.
  • Others float names like Lute, Lilith, Zestial, Rosie, Valentino, and Velvette as potential or secondary antagonists for later seasons, cross‑referencing older commentary and storyboard teases.

These are speculative but show where fan excitement is focused right now.

Main Season 3 Villain Candidates (Fandom View)

Below is a snapshot of the most talked‑about villain options and why people bring them up.

1. Alastor – The Big Favorite

Most fan and article discourse treats Alastor as the probable main villain of season 3:

  • He has:
    • A long‑term, carefully built‑up presence.
    • A reputation as one of hell’s most dangerous overlords.
    • A renewed, unchained power status after his deal is broken in season 2.
  • The tease about a charming anti‑hero stepping fully into villainy fits him almost too neatly.
  • Some fan posts and videos go as far as to say it has been “confirmed” he is the season 3 villain, though these are drawing conclusions from interviews rather than from an outright label stamped “Official Big Bad: Alastor.”

In story terms, that would make season 3 a clash between Charlie’s idealism and Alastor’s refusal to change , which also lines up with the show’s core themes.

2. Lilith – The Long Game Threat

Lilith is less likely to be “the” single villain of season 3, but almost certainly a major antagonistic force:

  • Creator commentary calls her the “big slow‑burn mystery” of the series, with answers unfolding “over the next couple seasons.”
  • It is stated she will definitely have a presence in season 3 , tying directly into Charlie’s family drama and the political structure of Heaven vs Hell.
  • Theory channels often position season 3 as:
    • A transition point where Lilith moves from an off‑screen mystery into an active driver of conflict.
    • Possibly a co‑villain or overarching chessmaster , even if Alastor is the more immediate, emotional antagonist.

So: Lilith looks like a major power player and narrative engine , but not necessarily the single focus of the “villain” marketing tagline yet.

3. Other Names in Theories

Fans love filling out a longer villain roadmap beyond season 3:

  • Lute
    • Heavily associated with Heaven’s side and vengeance for past events.
    • Some fans originally thought she might be billed as a main post‑season‑2 antagonist, but more recent talk leans toward support or secondary villain status.
  • Zestial, Rosie, Valentino, Velvette, Roo
    • These names circulate often in multi‑season villain lineups, with some Reddit posts proposing sequences like:
      • Season 2: Vox/Lute
      • Season 3: Alastor
      • Later seasons: Roo, Rosie, or others stepping up as primary threats.
* None of these have the same direct tie to the “friendly anti‑hero becomes villain” hint as Alastor, which is why they are usually framed as **future big bads** rather than the headline for season 3.

All of this is fan speculation , even when it cites old concept notes and interviews.

So, Who Will Be the Villain?

Putting it all together for your core question, “who will be the villain in Hazbin Hotel season 3?”:

  • Most likely candidate, supported by creator hints:
    • Alastor (Radio Demon) taking on a clear, central villain role after two seasons of being a dangerous ally.
  • Likely major antagonistic presence:
    • Lilith , who is confirmed as an important slow‑burn mystery with a presence in season 3 and is expected to drive larger, family‑ and Heaven‑related conflict.
  • Additional players and wildcards:
    • Lute, various overlords (Rosie, Zestial, etc.), and other Heaven/Hell figures may act as side villains, political threats, or setup for later seasons, but they are not as squarely framed as “the” season 3 villain in current public info.

Until an official logline, trailer, or episode outright states “X is the main villain of season 3,” everything stays probable but not guaranteed —with Alastor sitting at the top of that probability list. Information gathered from public forums or data available on the internet and portrayed here.
