Comparing these gangs, we can see that the greasers were initiated by Darry and Sodapop. This band fought mainly in Dallas. And the Tim Shepard Gang was mainly composed of teenagers, they used all kind of weapons to fight. Finally, the Brumly was created specially by illiterate guys but they were very brave.
The greasers are more of a family than a gang, they fight only when they need to, and they prefer skin over weapons, they are more of a family and they don’t just listen to one leader. When one of the group needs help the others will do almost anything to help, as shown when Dally pulls Jonny out of the burning church. Tim Shepard’s gang is made up of guys ranged from fifteen to nineteen and are a bunch of thugs who are ruled by Tim, they will fight for fun and are rowdier than the greasers, they prefer to use any weapon they can get including broken bottles and switchblades. Brumly’s gang is similar to Shepard’s, a group of guys who would “just get worse as they got older, not better.” Ponyboy thinks this gang is made up of illiterate hoods. He doubts that “half of them can read a newspaper or spell much more than their names.” Brumly’s gang members have “weird vocabularies,” likely because they are not educated.
