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 first Cylon War (Miniseries).
- Another Joker is on board Galactica during the Cylon attack and is launched in the first sortie against the Cylons before jumping to Ragnar Anchorage (Miniseries, Night 1). He apparently survives, as he is visible on the pilot's roster during "Act of Contrition".
