What Is the Joker's Official Profile?
The Joker's official profile is the character record published by DC Comics, not a fan wiki or a movie marketing page. It lists his first appearance in Batman #1 (1940), his creators Bill Finger, Bob Kane, and Jerry Robinson, his base in Gotham City, and one blank field: real name, unknown. Every other "official" Joker profile online traces back to that DC record or to a studio press kit for a specific film.
That split matters. The profile for the 2019 film Joker describes Arthur Fleck, a man with a job, a mother, and a diagnosis. The DC Comics profile describes a criminal with no confirmed identity. Both are official. They are not the same person.
What Is Joker's Real Name? Comics, Films, and Games Explained
Which Sources Publish an Official Joker Profile
- DC Comics character database: the canon record for the comics version, with first appearance, creators, and team affiliations.
- DC Studios and Warner Bros. press pages: cast lists and character notes for each film release.
- Studio production notes: the documents handed to press for Joker (2019) and Joker: Folie à Deux (2024).
- Licensed print references: DC encyclopedias and the Who's Who issues DC published in the 1980s.
Fan wikis borrow from all four. They add speculation, but the bones of the page come from publisher material.
What the DC profile contains
DC's record is short. It gives the first appearance, the creative team, a list of Gotham institutions tied to the character (Arkham Asylum, Blackgate), and the note that his real name and origin stay unrevealed.
Team affiliations shift by era. Writers have placed him with the Injustice League, the Legion of Doom, and various short-lived Gotham crews. None of those listings change the core record.
What the DC profile leaves blank
The real name field is empty on purpose. DC has kept the Joker unnamed since 1940, and editors have refused to lock in an origin. Height and weight appear in some licensed references and shift between printings, so treat those numbers as editorial choices rather than fixed facts.
Official Profiles for Each On-Screen Joker
Film and television profiles exist per continuity, because each actor plays a separate version of the character. Studios publish these in press kits, not in a shared database.
- Cesar Romero, Batman television series, 1966 to 1968.
- Jack Nicholson, Batman, 1989.
- Mark Hamill, voice role, Batman: The Animated Series, 1992.
- Heath Ledger, The Dark Knight, 2008.
- Cameron Monaghan, Gotham, 2014 to 2019.
- Jared Leto, Suicide Squad, 2016.
- Joaquin Phoenix, Joker, 2019, and Joker: Folie à Deux, 2024.
- Barry Keoghan, The Batman, 2022.
The Phoenix version is the only one with a standalone character profile built around a full backstory. Arthur Fleck has a birth name, a job as a party clown, and an address documented in the film's production notes. That level of detail does not exist for the comics Joker.
How to Tell an Official Profile From a Copy
Three checks separate a publisher page from a rewritten one.
- Look for a publisher or studio name on the page itself, not in the footer of an aggregator.
- Check whether the first appearance cites Batman #1 (1940) with no extra claims attached.
- Watch for invented detail. A page that states the Joker's real name, or gives a single origin as settled canon, is not following the official record.
Aggregator sites republish publisher text to capture search traffic. The wording changes, the facts do not.
Questions People Ask About the Joker's Official Profile
Is the Joker's real name known?
No. DC has left the name unrevealed in canon since the character debuted. Names used in films (Arthur Fleck) or in one-off comics belong to that version alone.
What is the Joker's first appearance?
Batman #1, published in 1940. DC's own profile credits that issue as the debut, and licensed reference books repeat it.
Is any Joker origin canon?
The Killing Joke (1988) offers one, and the story itself says the memory may be false. DC has kept the question open, which is why the profile lists no origin.
Does the Joker have an official age?
No fixed age is listed for the comics version. Film profiles give Arthur Fleck an age because the script requires one.
Why do different sites list different team affiliations?
Because the character has run for more than eighty years across many titles. Each era added and dropped teams. The stable facts stay the same across all of them: first appearance, creators, and an unnamed lead.
Why the Profile Stays Short
A character defined by an unknown past works better without a record. DC's profile reflects that choice: it documents what the publisher will confirm and stops there. Read it as the floor, not the ceiling, and treat any page that fills in the blanks as someone's version rather than the official one.
