Punk Leader is a male Tau'ri and the leader of a punk gang. He also has one sister, Allyson Martin. He encountered Teal'c when he came to Colorado Springs to find a place 'to get ready'. He asked Teal'c where he got his tattoo. At first Teal'c didn't answer, but when he persisted Teal'c took his throat and told him how it was done. When Teal'c left, he told his sister to leave because he claimed no one wanted her around. (SG1: "Bane")
