There is a long line of anime characters who have hidden the fact that they are powerful enough to defeat most people with ease. There is an equal number of characters on the opposite end of the spectrum. These characters like to brag about their supposed sky-high power level, even though they aren't nearly as strong as the major protagonists.
By continuing to boast about their own strength, they begin to believe that they really are as powerful as they say, which often leads to them experiencing some kind of misfortune as a result. These characters are usually the comedic relief in the series and can be vastly entertaining to watch.
