13 Worst Anime in 2025 – Regret Watching These Nightmares!

Anime has given us masterpieces, but some shows are just outright disasters. Whether it’s terrible animation, nonsensical plots, or unbearable characters, some series are simply the worst anime in the world. Let’s dive into the 13 worst anime to watch in 2025, featuring some of the worst-rated anime ever!

1. EX-ARM (2021)

Widely considered one of the worst anime series ever made, EX-ARM is an absolute trainwreck. With horrendous CGI that looks like a failed video game project and a plot that makes no sense, this anime is a must-avoid. It remains one of the worst-rated anime in the world.

2. Pupa (2014)

Ever wondered what it would be like if an anime tried to mix body horror with an incomprehensible story? Pupa is your answer. With only 4-minute episodes filled with grotesque imagery and zero character development, this show is often on the worst 13 anime ranking lists.

3. Vampire Holmes (2015)

A detective anime with zero detective work? That’s Vampire Holmes! With boring characters, lifeless animation, and a non-existent plot, it’s easily one of the 13 worst anime of all time.

4. Hanoka (2006)

One of the first anime entirely made in Flash, and it shows. The poor animation, forgettable story, and stiff characters make Hanoka one of the worst anime to watch.

5. Gibiate (2020)

Marketed as a next-level sci-fi anime, Gibiate turned out to be an absolute disaster. From awful character designs to laughable dialogue, it belongs in the worst anime ranking.

6. Forest Fairy Five (2016)

If you’ve never heard of Forest Fairy Five, consider yourself lucky. The anime has some of the worst CGI ever, making it painful to watch.

7. Skelter Heaven (2004)

This anime is a perfect example of what happens when bad animation meets an even worse story. With its cringe-worthy mecha fights, it deserves its spot on the worst-rated anime in the world list.

8. Mars of Destruction (2005)

Some say this is the worst anime of all time. The voice acting is robotic, the plot makes zero sense, and the action scenes are laughably bad.

9. Eiken (2003)

This anime is infamous for its absurdly exaggerated fan service. With no real plot and disturbing character designs, Eikenis one of the worst anime series ever made.

10. Tesla Note (2021)

If you thought EX-ARM was bad, Tesla Note somehow manages to compete. The CGI is atrocious, and the story is a confusing mess.

11. My Sister, My Writer (2018)

Horrible animation, cringeworthy dialogue, and a premise that’s just uncomfortable. This show is often listed in the worst anime ranking.

12. Dark Cat (1991)

An old but legendary bad anime. With incomprehensible plot points and terrible animation, Dark Cat is still one of the worst anime of all time.

13. Conception (2018)

A fantasy anime where the protagonist must impregnate 12 magical girls to save the world. Yes, that’s actually the plot. It’s as bad as it sounds, making it one of the worst anime to watch.

Final Thoughts

If you value your time, stay far away from these worst-rated anime in the world. From horrendous CGI to awful storytelling, these anime fail in every aspect. Avoid them at all costs!
