Sidney "Sissy" Fess is a member of Bad Bessie's gang.
Red travels to Rogue Valley to hunt down Bad Bessie, and battles with her men. "Sissy" Fess is one of the bandits that Red fights. He attempts to kill Red by hurling boulders at him. As with many NPCs in Red Dead Revolver, there is more than one of him. The player will encounter three or more instances of Sidney in Rogue Valley, including one who duels with Red.
The player can unlock Sidney as a playable character in Showdown Mode by successfully completing the mission "Rogue Valley" on Bounty Hunter Mode or by purchasing the Bloody Rock from the Shop interface at the start of the mission "Fort Diego".

- Sidney will either appear in green colored clothes, or white clothes.
- His nickname "Sissy", combined with his last name "Fess", as well as his preferred method of attack, might be a tongue-in-cheek reference to the ancient Greek legend of Sysiphus; a king who was punished by Hades, to roll a heavy stone up a hill that would roll back down when he was finished, for all eternity.
