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 for Galactica during "Act of Contrition". This is likely the same Joker who pilots Viper 1104 during the first Cylon attack on Galactica (Miniseries)
