Character Identity Across Worlds

Problem This Solves

When fictional characters appear across multiple adaptations and media — Sherlock Holmes in Conan Doyle's stories, BBC's Sherlock, Guy Ritchie's films, CBS's Elementary — their details often contradict each other radically. Watson changes gender, the setting jumps a century, parentage is rewritten. Yet audiences still recognize "the same character." Standard philosophical frameworks fail here: Meinong's nonexistent-object theory treats characters like round squares, and David Lewis's possible-world semantics ties character identity to the properties of a single fictional world. Neither explains how a character persists across worlds with irreconcilable properties.

Transmedia creators face a practical version of this puzzle every time they adapt a character: which traits are essential, which are expendable, and how far can you push changes before the character becomes someone else entirely?

Key Principle

Lapointe (Ch. 3) proposes that fictional characters are quasi-existent — "neither existent in the real world (i.e. as people), nor only existent within the delimitations of their fictional contexts (i.e. true by virtue of their inter-fictional carry-over). Rather, they occupy a middle-position that is best designated as quasi-existent." They are "more than the sum of their textual iterations and achieve continuity of identity independently of their attendant worlds."

Character identity across iterations follows a family resemblance model (Wittgenstein), not a checklist of essential properties. "Any seemingly defining aspect of a fictional character may be subject to radical change. A character, via her multiple iterations, would be identifiable more in terms of 'family resemblances' than by any shortlist of necessary/sufficient conditions." There is, however, a tipping point: "Sherlock Holmes can only withstand so many changes — in profession, in character, even in name — beyond which he is transformed into a categorically different character."

Pearson (Ch. 6) operationalizes this with six components of character: (1) psychological traits/habitual behaviours, (2) physical traits/appearance, (3) speech patterns, (4) biography, (5) interactions with other characters, (6) environment/setting. The presence, absence, or modification of these components signifies link strength across iterations and drives canonicity debates.

Good Examples

• BBC's Sherlock: Holmes and Watson are displaced from Victorian England to modern London. Watson keeps his name, military background, and role as chronicler; the address stays 221B Baker Street. Hereditary dependence (how did they end up a century later?) is never explained because it doesn't need to be — "it does not carry over into fiction, and it is never specified otherwise." The family resemblance cluster is strong enough.
• Superman: Red Son: Superman is reimagined as a descendant of Lex Luthor sent from the future, not the son of Jor-El from Krypton. Total genetic and biographical overhaul, yet the character remains recognizably Superman because the core persona — the powers, the moral weight, the cultural role — persists.
• CBS's Elementary: John Watson becomes Joan Watson; Moriarty is recast as a woman who adopts the persona of Irene Adler. Gender, one of the most seemingly fixed attributes, changes without destroying identity — demonstrating that quasi-existence frees creators from biological consistency.

Bad Examples

• Overloading change past the tipping point: Lapointe warns that "one can imagine a retelling of Sherlock Holmes in which he never became a famous detective living at 221B Baker Street, but solely devoted his life to beekeeping, away from London." At that point, too many components of the family resemblance cluster have been stripped. The character ceases to be Holmes in any meaningful sense.
• Treating names as rigid designators: Assuming a character must keep their exact name to remain themselves. Maurice Leblanc's "Herlock Sholmes" recapitulates Holmes's plots and persona — "stipulating a necessary and exclusive link between fictional name and identity... would here seem meagre and doctrinaire."
• Reducing characters to property lists: Lewis's inter-fictional carry-over is useful but "need not stamp out quasi-existence, nor does it address all the thorny issues that quasi-existence ably encompasses." Treating a character as merely the collection of facts stated about them in a single narrative misses the quasi-existent dimension that audiences actually respond to.

Key Quotes

• "We ascribe attributes to fictional entities and thereafter imagine them as looking and acting in a certain way. Conversely, we establish boundaries and limitations within which we accept a range of varied portrayals." — Lapointe, Ch. 3
• "Too often do we recall fictional characters vividly, yet not a single word of the text in which they came alive." — Chatman (1978), quoted in Pearson, Ch. 6
• "Fictional characters are more than the sum of their properties as evoked in fictional worlds." — Lapointe, Ch. 3
• "When an ostensibly imaginary object appears within a culturally sanctified representational context, it achieves a different status from 'beingless object.'" — Lapointe, Ch. 3

Rules of Thumb

1. Use the six-component test. When adapting a character, map which of Pearson's six components (psychological traits, appearance, speech, biography, relationships, setting) you are preserving, modifying, or discarding. The more you discard, the weaker the link.
2. Preserve the family resemblance cluster, not a checklist. No single trait is strictly necessary. But enough overlapping traits must survive to maintain recognition. Think of it as a centre of gravity, not a set of load-bearing walls.
3. Names are not identity. Characters can change names across iterations (Milverton to Magnussen, "Herlock Sholmes") without losing identity, and sharing a name does not guarantee identity.
4. Biology is not identity. Fictional characters lack hereditary dependence — they "do not benefit from any genetic/chromosomal stability but still remain who they are as fictional constructs." Gender, parentage, era, and even species can shift.
5. There is always a tipping point. Quasi-existence is permissive but not unlimited. At some threshold of accumulated change, the character becomes categorically different. Respect the boundary even if you cannot draw it precisely.
6. Audiences carry knowledge forward. Lewis's inter-fictional carry-over is real: audiences import character knowledge from prior texts. New installments should build on rather than silently contradict the accumulated portrait.
