Fan Casting Large and in Charge in Sort by Tropes

The tendency to visually depict leaders of an organization as large, physically intimidating people. This could be because people are more likely to follow orders from a big guy than a small one (because of the physically intimidating height). Exactly what flavor of "big" he (or she) will be depends chiefly on the character's personality, or sometimes species. He could be an Adipose Rex to symbolize his greed and decadence, but could instead be a towering seven-foot-tall man complete with a Heroic Build.
