What are the characteristics of the characters in the novel 'The Outsiders'?

All the Greasers in The Outsiders are extremely loyal.  If
someone starts a fight with one member then they all fight, they are true to one another
and have created a family for themselves.  Loyalty is a key characteristic of the
Greasers.  When Johnny killed Bob, Ponyboy ran away with him, because he knew he was the
reason Johnny did this and was loyal to his friend.  While they look tough on the
outside, on the inside they are loving and loyal to their “family”.  All members of the
gang love each other, but it is most evident between Ponyboy’s love for Sodapop, Dally’s
love for Johnny and of course between Ponyboy and Johnny.  While Darry doesn’t seem to
love Ponyboy throughout the boy, we discover that he does love him and the reason he
works so hard and is tough on Pony is to make sure that they get to stay together as a
family, again enforcing the importance of family.  The Greasers are tough and get into
many rumbles, but the rumbles are not what prove that they are courageous.  The fire is
the best example to prove that the Greaser are courageous, even the reluctant hero,
Dally, joins Johnny and Ponyboy in going back into the fire to save the kids.  Johnny
was brave enough to knowingly risk his life to save the kids and never regretted this
heroic act.  Loyalty, love, courage and bravery are some of the Greasers characteristics
in The Outsiders.  These characters are much deeper than they appear on the outside,
often in stories, the label of, ‘greaser’, ‘hood’ or  ‘outsider’ is as deep as these
tough guys goes, painting them as the rough and tough villain.  The Outsiders is
refreshing because it gives us the opportunity to see that ‘greasers’ are so much more
than slicked back hair and a leather jacket.
