Joker is the known call sign for at least two pilots on Galactica:
- A restored Viper Mark II, Viper 1104,has a nameplate for a Lieutenant Pete Hickey, who was likely a Viper pilot assigned to Galactica during the first Cylon War (TRS: "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 (TRS: "Miniseries, Night 1"). He apparently survives, as he is visible on the pilot's roster during "Act of Contrition".
- Name and rank confirmed based on Official Battlestar Galactica Props & Costumes Auction Archive listing for Lt. Pete "Joker" Hickey's nameplate.
