Steve (400 Days)

Steve is a character mentioed by Russell in 400 Days. He was a leader of group of seven people, including Russell, teacher and his wife, father and her daughter and one another survivor.

Post-Apocalypse
Steve was the leader of a tiny group, and he didn't allow anyone else to the group as the thought seven was a "magic number". Steve presumably killed a lot of survivors and took their equipment due to this, and made Russell leave the group. Steve's fate is left unknown.
