Regarding the topic of dragons:
The mythology of Dragons has become so expansive that I don't think there is a 'true' Dragon. If you explore European media with dragons in them, you'll notice that some actually have two legs (mostly used to make roaming the lands viable) and wings as arms. This is seen in Skyrim and, I believe, the movie Reign of Fire. Haven't watched that for a loooong time though.
But at the same time, you also have the common 4 legs with wings dragons that are seen commonly in media such as the game RuneScape.
Other iterations include the term 'Dragon' used as a whole species of dangerous reptiles, alike to how the word 'Dinosaurs' is used. This is seen in, for example, the movie, "How to train your Dragon". The variety in that movie is a bit too broad for my liking, but it still helps prove the point.
We then have the Chinese iteration of dragons, which I believe aren't commonly evil creatures but instead used as a genuine positive symbol. They also are more similar to snakes and serpents instead of creatures such as the Komodo Dragon as they represent a long, slithering body while still having legs for some odd reason. And I'm sure different cultures have different perspectives on what a 'dragon' is.
Because of how people despise repitition and clichés, the media market has to be very careful when touching the concept of these fire-breathing reptilian beasts. Films and games have to try to make them unique to set it apart from others in terms of lore, characteristics and the obvious one, what they actually are. Some media take a whole different approach altogether and don't try to name a creature they are featuring as a dragon at all, but take similarities from it. That way, the only thing the audience can do is call it one. It's kind of what I'm doing with something I'm working on. I'm very fearful of just being repetitive, so I'm trying to make it stand out while carefully mixing in different concepts.
