Thane is an aggressive, virtually uncontrollable member of Commander Croft's team. With Croft, he was in on keeping the plunders of the Cylon's platinum mine to themselves, and is responsible for killing a higher unnamed commander. He is an expert in any variety of alien environments, and brags as such to anyone who would listen, and this is the reason he is selected for the mission to Arcta to destroy the Ravishol Pulsar.
Even before leaving Galactica, Thane attacks Sergeant Vickers and uses a knockout capsule on the warrior, thus paralyzing him.
He is in on the plot to ditch the expedition when the right opportunity occurred, and knocks out a Ser Theta to obtain his clothing. However, the Cylons capture Thane, though he manages to reveal nothing of their mission. To his credit, he takes several Cylons with him by passing off a hand mine as a recording device that would tell the Cylons all they need to know about The Fleet (Gun on Ice Planet Zero).
