I'm not sure specifically what the 'coco bear true story' is without more context. It could be about a bear named Coco and some real - life events related to it, like its adventures in the wild, or how it was rescued perhaps.
The key elements of the 'coco bear true story' could vary greatly. It might be centered around the bear's family. If Coco has cubs, then the story could be about how it raises them, protects them from predators. Another key element could be any threats to Coco's existence, such as habitat loss due to deforestation or human encroachment. How Coco overcomes or is affected by these threats could be central to the true story.
Disney Coco isn't directly based on a specific true story. Instead, it takes inspiration from Mexican culture and themes related to family, memory, and the afterlife to craft a compelling fictional narrative.
