A few anime are often brought up as sharper or more self-aware alternatives to Detective Conan , but few directly “ruthlessly mock” it. The closest fits are usually The Kindaichi Case Files , Detective School Q , and Tantei Opera Milky Holmes , which play with detective tropes rather than openly roasting Conan itself.

Closest matches

  • The Kindaichi Case Files : This is the most obvious rival in the classic schoolboy-detective lane, and fan discussions often frame it as the series Conan fans should know about.
  • Detective School Q : A younger, more playful mystery series that mirrors some Conan-style setup while leaning into a lighter team dynamic.
  • Tantei Opera Milky Holmes : A parody-heavy detective anime that intentionally exaggerates the genre’s habits, so it can feel like a jab at mystery formulas in general.
  • Un-Go : More of a serious deconstruction than a comedy roast, but it comments on detective storytelling conventions in a way Conan usually does not.
  • Neuro: Supernatural Detective : This one is more satire-adjacent, with an over-the-top detective premise that makes genre absurdities part of the joke.

If you want actual mockery

If by “mock” you mean parodying Conan’s style, not just matching its genre , Tantei Opera Milky Holmes is probably the best fit from the commonly recommended lists. If you mean a show that indirectly exposes Conan’s formulaic habits , then Kindaichi is the strongest parallel because it emphasizes darker stakes and a less toy-like detective rhythm.

What the forum chatter suggests

The public recommendation lists lean more toward “anime like Detective Conan” than “anime that roast Detective Conan,” so the evidence points to parody of detective tropes , not a widespread ongoing anti-Conan gag. A direct, consistent industry-wide mockery of Conan is not what these sources show.

Best pick

  • For parody : Tantei Opera Milky Holmes.
  • For rival energy : The Kindaichi Case Files.
  • For genre deconstruction : Un-Go or Neuro: Supernatural Detective.

TL;DR: there isn’t a famous anime that mainly exists to savage Detective Conan ; the nearest things are parody-heavy detective shows like Tantei Opera Milky Holmes and rival-style mystery series like Kindaichi.
