Peacocks are known in real life for their extravagant feathers with colorful patterns. Because of how ostentatious these feathers appear, these birds tend to be depicted in fiction as characters who are vain, prideful, or self-centered. While some of them may still be mostly kind characters who are just fond of attention, others can be straight-up villainous.
Please note that the long, colored feathers are not the peacock's tail. Rather, it's called a "train", and the feathers are actually attached to the peacock's back. The peacock's real tail feathers are short and brown, and can be found under the train. Also note that, while some examples involve female characters (i.e. peahens), the big, colorful feathers associated with this trope are exclusive to male peacocks in real life.
This trope is the origin of the old saying "proud as a peacock," as well as the fact that a group of peacocks is called an "ostentation." The peacock is also one of animal symbols of the Seven Deadly Sins, i.e Pride (the other is the lion).
