Among the thousands of fictional characters listed in film, comic book, and animation encyclopedias, those whose names start with B hold a unique place. Batman, Bambi, Barbie, Bluey: these names transcend decades, media, and legal boundaries. Rather than providing an alphabetical inventory, this article compares their trajectories from the perspective of legal status and commercial longevity, two data points rarely intersected in typical lists.
Legal Status of Fictional Characters Starting with B: Public Domain and Intellectual Property
The question of the public domain reshapes the landscape of these famous characters. Not all benefit from the same level of protection, and the disparities are considerable from one character to another.
| Character | First Appearance | Public Domain Status (United States) | Residual Protection |
|---|---|---|---|
| Buck Rogers | 1929 | Public domain (copyright not renewed) | Possible trademark |
| Betty Boop | 1930 | Public domain since 2026 (first appearances only) | Later versions and trademark protected |
| Batman | 1939 | Due in 2035 (original version) | Features added after 1939 protected longer |
| Bambi | 1942 (Disney film) | Not yet reached | Disney trademark and design protected |
| Barbie | 1959 | Not yet reached | Active Mattel trademark |
| Bluey | 2018 | Not yet reached | Expanding multi-brand licenses |
This table highlights a specific phenomenon: the transition to public domain only frees a historical version of the character. The 1930 version of Betty Boop has been in the public domain in the United States since 2026, according to the Duke Law Center for the Study of the Public Domain. Her modernized silhouette, merchandise, and name as a trademark remain protected.
For fictional characters starting with b, this distinction between expired copyright and active trademark radically changes what an independent creator can or cannot do.
Buck Rogers and Betty Boop: What the Public Domain Changes for Creators
Buck Rogers is already freely exploitable in the United States. His comic book copyright was not renewed, placing him in a rare situation among popular fictional characters. An illustrator, independent publisher, or video game studio can take up the original character without a license.
Betty Boop, on the other hand, illustrates the complexity of the system. Her first appearances from 1930 entered the American public domain in 2026. Her redesigned versions in the following decades remain protected by copyright, and some elements of trademark persist independently of copyright.
This overlap of protections explains why characters theoretically “free” are never completely so. A creator who faithfully reproduces the 1930 version of Betty Boop acts legally. Those who reproduce the marketed version on contemporary merchandise expose themselves to trademark infringement actions.
Batman in 2035: A Case Study to Anticipate
The first version of Batman, published in 1939, is set to enter the American public domain in 2035, according to the Duke Law Center for the Study of the Public Domain. This only concerns the original Batman: gray and purple costume, absence of sophisticated gadgets, a more brutal personality than later versions.
Features added after 1939 will remain protected well beyond 2035. The Batmobile as we know it, the Joker in his successive incarnations, the extended universe of Gotham: all of this falls under distinct layers of rights. DC Comics will maintain tight control over the majority of what constitutes Batman in the current collective imagination.
Bluey and Barbie: Fictional Characters Turned Commercial Ecosystems
At the opposite end of the spectrum, Bluey represents a contemporary model where the fictional character becomes a licensing platform. In September 2026, Mattel and BBC Studios announced a multi-year global agreement integrating Bluey into several brands of the group: Barbie, Hot Wheels, Fisher-Price, Polly Pocket, and UNO.
This cross-licensing strategy distinguishes Bluey from older characters that developed linearly (series, then merchandise, then adaptations). Here, the character simultaneously fits into existing brand universes, accelerating its commercial spread.
- Barbie took several decades to transition from toy to blockbuster film, relying on a gradual accumulation of merchandise and animated adaptations since the 1980s.
- Bluey achieved multi-brand franchise status in less than ten years, thanks to a comprehensive licensing agreement covering multiple product categories simultaneously.
- Batman has generated licensing revenue since the 1960s, but the fragmentation of his rights among publisher, studio, and trademark holder complicates each negotiation.
Television Fame and Off-Screen Expansion
The trajectory of Bluey confirms that the fame of an animated character no longer relies solely on its television broadcast. Integration into existing toy lines (Fisher-Price, Hot Wheels) offers shelf visibility that far exceeds the audience of the series itself.
In contrast, a character like Bambi, despite its global recognition, has never been developed into a comparable licensing ecosystem. Cultural longevity does not guarantee commercial diversification.
Disney Heroes, Comic Book Heroes, and Recent Animation Heroes: Three Distinct Logics
Fictional characters starting with B can be divided into three families with very different logics:
- Disney characters (Bambi, Belle from Beauty and the Beast) benefit from extended legal protection and centralized exploitation by a single studio, which controls the entire chain.
- Comic book heroes (Batman, but also Batgirl or Black Panther) accumulate layers of rights over the decades, making their legal status increasingly fragmented.
- Recent animation characters (Bluey, Ben 10) are born in an environment where multi-brand licensing agreements sometimes precede the narrative maturity of the character.
This distinction clarifies why comparing Batman and Bluey solely based on their popularity makes little sense. Their business models, legal horizons, and distribution strategies have almost nothing in common.
The common denominator remains the initial letter and the ability to transcend formats. A durable fictional character is one that survives its original medium, whether through the public domain, cross-licensing, or periodic reinvention by a dominant studio.
