Thumper is a callsign for at least one pilot in the Fleet following the Fall of the Twelve Colonies.

A pilot with this callsign is assigned to Galactica (TRS: "Bastille Day"), while another pilot is assigned to Pegasus (TRS: "Pegasus").


  • The number of pilots with this call sign is nebulous, as no evidence exists to definitively either prove or disprove the existence of two pilots with this callsign.
  • To wit, it is entirely possible that only one Thumper exists in the Fleet, and is reassigned to Pegasus after the arrival of Admiral Helena Cain, who effectively assumes command of the Fleet and transfers personnel between the two extant battlestars in Re-imagined Series' "Pegasus".
