Beatty is a indirectly characterized as intimidating in "Fahrenheit 451".one example of this is when Montag and Mildred are afraid of him:"Montag lay back against the wall and then slowly sank to a crouching position and began to nudge the books,bewilderingly with his thumb and his forefinger."He was shivering and he wanted above all to shove the books back in the ventilator again. But he could not face Beatty."This shows indirect characterization because this passage does not come out and tell us specifically that he is intimidating.
Beatty was indirectly characterized as captain. One example of this is when all the fireman were talking about a past fire: "Captain Beatty there...."(Fahrenheit 451 pg.33). This is an example of direct characterization because the words are being quoted by the characters in the story;the audence does not have to assume he is a captain.
