Joker is the known call sign for at least two pilots on Galactica:
- A restored Viper Mark II has a nameplate for a Lieutenant Pete Mickey, who was likely a Viper pilot assigned to Galactica during the Cylon War (Miniseries).
- Another Joker is visible on the pilot's roster during "Act of Contrition". This is likely the same Joker who pilots Viper 1104 during the first Cylon attack on Galactica (Miniseries).
