"The real character of the gang," Dally was arrested his first time at the age of ten. He spent three years on the "wild side" of New York and likes to blow off steam in gang fights. He is the most dangerous member of the bunch—not even Darry wants to tangle with him—but he is still a part of their greaser "family." The local police have a large file on him, and he has just gotten out of jail at the opening of the novel. While "the fight for self-preservation had hardened him beyond caring," there are two things that have meaning for him: jockeying on ponies (the "only thing Dally did honestly") and Johnny.
In Tulsa, lacking a rival gang, Dally hates the Socs. Fighting them is frustrating, however, because he knows that beating them doesn't take away any of their social advantages. During fights he takes particular care to look out for Johnny, and so he helps the boys after the murder even though it could return him to prison. Johnny returns Dally' s care with a devoted admiration. Consequently, Johnny views him as a heroic gentleman of courage, like those in Gone with the Wind When Johnny is dead the rest of the gang realizes he was Daily's breaking point. Having lost the one thing he really cared about, Dally sets himself up for death. After robbing a store, he threatens the pursuing cops with an empty gun. He dies in front of his friends in a hail of bullets.
