Belzebubs
JP Ahonen's webcomic about a black metal family man made the jump to animation and lost none of its warmth in translation. Sløth, frontman of the world's least successful satanic band, is a stay at home dad raising Lilith and Leviathan with his wife Lucyfer, and the show's genius is playing every domestic beat completely straight: school interviews, in law visits, band practice in the garage, all conducted in corpse paint. The mockumentary confessionals, where family members speak to a documentary crew that is never explained, give it a Modern Family rhythm filtered through church burnings.

Our Review
Belzebubs (2025) is a animation and comedy series from Yle (Finland). It has built a run of 13 episodes at roughly 22 minutes each. It premiered on September 24, 2025. It is currently running. It runs 1 season.
What Belzebubs Is About
Sløth is a well-meaning stay-at-home dad striving to balance family life with his ambitions as the frontman of a heavy metal band, alongside his unconventional family navigating everyday chaos.
What to Expect When You Watch
Episodes run about 22 minutes, which keeps the pace tight, the full run covers 13 episodes, spread across 1 season and it leans into its animation/comedy roots while leaving room for the quieter character beats.
Performance-wise the series leans on Andrew Wheildon-Dennis, Jess Robinson and Pippa Haywood to carry the emotional weight, with the rest of the ensemble filling out the world around them.
Cast and Creative Team
Andrew Wheildon-Dennis, Jess Robinson, Pippa Haywood, Amalia Vitale and JP Ahonen lead the cast.
Key roles include Andrew Wheildon-Dennis as Sløth (voice, English); Jess Robinson as Lucyfer (voice, English); Pippa Haywood as Nana (voice, English); Amalia Vitale as Blasphe-My (voice, English); JP Ahonen as Creator / based on the webcomic.
Why It Stands Out
Fans of animation and comedy have a clear reason to give this one a shot. It sits comfortably alongside Yle (Finland)’s other originals and it commits to its premise instead of hedging between tones.
Released in 2025 and carried by Yle (Finland) with the series still running, it lands hardest with animation and comedy viewers.
How Belzebubs Compares
If Belzebubs lands for you, the next stops are Avatar: The Last Airbender, Death Note and X-Men: The Animated Series, which share its animation/comedy lean.
Each of those sits at a different point on the same spectrum, so they make a natural follow-up once you finish the run here.
Where to Stream
Belzebubs comes from Yle (Finland). Check your preferred platform for current availability, since regional rights move around.

On the whole Belzebubs is the kind of series that rewards a patient watch, with Andrew Wheildon-Dennis and Jess Robinson doing the heaviest lifting, a tone that stays true to its animation/comedy roots, It has held up since 2025 and so if the premise sounds like your lane, the execution holds up.
The Bottom Line
Belzebubs is a safe bet for anyone already inside the animation and comedy lane, at 13 episodes it is an easy run to work through and so there is little risk in starting it tonight.
Verdict: 7.5/10. Watch it if you want animation/comedy you can settle into.
