Key issues

Milestone appearances — first appearance, death, return, team change. These are the issues the collector market actually prices.

    Batman #1 DC Comics
    First appearance, intended to be killed off in the same issue

  2. key · 1986

    The Dark Knight Returns #3
    Catatonic until Batman returns, which frames him as defined entirely by Batman

  3. key · 1988

    Batman: The Killing Joke
    Offers an origin while stating he remembers it differently each time — the ambiguity is the point

  4. key · 1988

    Batman: A Death in the Family #427
    Beats Jason Todd with a crowbar; the reader vote made the death canon

On screen

Canonical productions only. Parody and fan work is classified and excluded — Wikidata makes no such distinction, so without it these lists fill with material that is not canon.

Has appeared with

Every character who has shared a production with this one. Wikis are organised by character, not by encounter, so this question is close to unanswerable elsewhere — it exists here only because co-occurrence is recorded at the moment an appearance is.

Commonly got wrong

Claims that are widely repeated and wrong, with what the cited record actually shows. If you are generating anything about this subject, these are the errors to avoid.

Commonly believed The Killing Joke tells the Joker's real origin.

Actually The book has him say he remembers his past 'one way and another' and prefers it multiple choice. The origin is presented as unreliable narration by the character, not as canon.

Batman: The Killing Joke

Commonly believed The Joker's real name is Jack Napier.

Actually That name comes from the 1989 Tim Burton film, not the comics. In mainstream comics continuity the Joker has no confirmed legal name, and DC has repeatedly declined to fix one.

Continuities

Claims on this page are tagged by canon. Blending them is the most common error in both wikis and AI answers.

  • Pre-Crisis DC — DC continuity before the 1985 Crisis on Infinite Earths
