Region Specific Continuity
The mythology of a series, or the characterization of its characters, change depending on the country
Most series have a set continuity that never change. However, some series keep their continuity rather ambiguous. This often leads to various areas having their own take on the characters and story. Compare to Depending on the Writer and Alternate Universe.
- Marvel's Transformers comic had a separate UK edition which came out more often, where half the issues were reprints of the American version and half were new material. So the UK continuity included more stories than the US continuity, and some of the stories they had in common were changed in meaning (for instance, there was a story arc where the extra material added for the UK version revealed that the central villain was an imposter, because otherwise it would have contradicted earlier UK-only stories with that villain).
- Back in The '80s My Little Pony had a a clear split between the UK and American continuities. Most of the characterization was the same as the toys but several characters had different personalities in the cartoons (most noticeably Wind Whistler being The Spock instead of The Ditz) than in the toys and comics. The general plot was different between the cartoons and UK comics was different as well
- Sonic the Hedgehog used this trope in its early years. Back before Sonic Adventure canonized the Japanese interpretation, the main three continuities were the Japanese, British, and American continuities. Each had different characterizations and their own changes to the plot (though the British and American ones were mostly identical). The changes are most noticeable in the the adaptations, particularly if you compared the Archie comics with the Fleetway comics. One large change was to the setting itself. In Japan, Sonic always lived on Earth amongst humans. In the Americas and UK, Sonic lived on an alien planet called "Mobius" populated with nothing but anthropomorphic animals. Adventure killed Mobius, however the Archie's adaptation and Fleetway adaptation kept using the setting due to both revolving around Mobius (to create a middle ground, Archie revealed that Mobius was Earth All Along. Another change was Sonic's personality. Sonic had a laidback carefree personality in Japan but a cocky attitude elsewhere. The games abandoned the western portrayal until Sonic Colors added it back. Unusually, both the Japanese Sonic X and Sonic the Hedgehog: The Movie take inspiration from the American canon (Sonic living on an alien planet in the former and Sonic's attitude in the latter).
