Leoben Conoy is a fictional male Cylon in the Battlestar Galactica series. The character was portrayed on screen by Callum Keith Rennie. Leoben is a Number Two model Cylon.
In the miniseries, a Number Two Clone is found hiding in a secret weapon storage known as the Ragnar Anchorage. The clone is sick from radiation poisoning. The Anchorage is located in a cloud which is deadly to Cylons but this one is on the verge of death. The Clone holds Commander William Adama captive in order to barter for a spaceship off the space station. In the ensuing battle to recover Adama, the clone is killed. It is this moment on that Galactica discover that the Cylons have taken on a human form and anyone could be a Cylon.
Leoben models seem to have a fascination with Kara Thrace for some reason. When the Leoben model was captured and interrogated on the Galactica, he expressed an interest in Kara Thrace.
On New Caprica, a Leoben clone pretended with Kara that they were married. Every so often, the Leoben model would be killed by Kara. The Leoben would resurrect into the body of another clone and the cycle would repeat itself. Kara would kill and he be regenerated.
Leoben fooled Kara into thinking that Kara had a daughter. Kara rejected the child but when the child hurt herself, Kara showed concern. After the rescue of the civilians on New Caprica, the real mother of the small child came forward and Kara felt sad to see her to leave.
When they landed on New Caprica, Kara was accompanied by a Leoben as she surveyed the surrounding area. Kara came across remains of a person on bike, that person had the dog tag of her name. The Leoben walked away, looking worried and scared.
