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).
Subtrope of Animal Stereotypes. May overlap with Peacock Girl. Compare Cocky Rooster for another bird that is commonly depicted as arrogant. Not to be confused with Agent Peacock, though that trope's name does come from the stereotypical association between peacocks and vanity.
- Kung Fu Panda 2: Lord Shen, the Big Bad, is a peacock whose ego leads him to attempt to take over China and commit genocide against the pandas.

At one point, Shen declares it "Year of the Peacock" effective immediately. His lackey, Boss Wolf, points out that it's the middle of the year. Shen simply glares at Boss Wolf, and Boss Wolf quickly agrees that it's the Year of the Peacock.

C'mon, baby, let me see what you hiding underneath
I wanna see your peacock-cock-cock

I assure you, I'm no sissy
I'm a man, I wear the plumage of a man.
