Dragons are commonly portrayed as serpentine or reptilian, hatching from eggs and possessing extremely large, typically scaly, bodies; they are sometimes portrayed as having large eyes, a feature that is the origin for the word for dragon in many cultures, and are often (but not always) portrayed with wings and a fiery breath. Some dragons do not have wings at all, but look more like long snakes. Dragons can have a variable number of legs: none, two, four, or more when it comes to early European literature. Modern depictions of dragons are very large in size, but some early European depictions of dragons were only the size of bears, or, in some cases, even smaller, around the size of a butterfly.
Although dragons (or dragon-like creatures) occur in many legends around the world, different cultures have varying stories about monsters that have been grouped together under the dragon label. Chinese dragons and Eastern dragons generally, are usually seen as benevolent, whereas European dragons are usually malevolent (there are of course exceptions to these rules). Malevolent dragons also occur in Persian mythology and other cultures.
Dragons are particularly popular in China. Along with the phoenix, the dragon was a symbol of the Chinese emperors. Dragon costumes manipulated by several people are a common sight at Chinese festivals.
