The main differences can lie in plot details. Sometimes adaptations might simplify or expand certain storylines for better presentation on the new medium.
Such comics usually have bold and graphic depictions, often crossing moral and ethical boundaries. They might focus on themes of excess and lack the depth or storylines found in more mainstream comics.
The image of a bear with a Christmas hat in a cartoon is usually very cute and festive. The bear might have a big smile and be surrounded by Christmas decorations.
Perhaps it's a story of adventure and survival, with the farmer's life turned upside down by the presence of the evil dragon. The farmer might have to use their wits and skills to protect their land and family.
The similarities could include similar character archetypes, similar use of visual cues for emotions or plot points, and similar overall tone and mood. Plus, the way the story builds tension and resolves conflicts might have some resemblance.
