Badass Cylons
From Wiki Frakr
When the series started, all kind of Cylons seemed to be badass, especially the schizophrenic Boomer. But unfortunately, they badass-ness has been overrun somewhere in the end of the second season, where Caprica-Six and the resurrected Boomer realized, peace must be sought with the humans.
This was a great choice, because that way they failed their first, most badass goal, to erase humankind, so the show didn't come to an end in the second season.
When the The Cylon Civil War started, they managed to kill some Religious Cylons.
Badasses are: Number One, Number Four, and someone else.
Note that Rummy is also a badass, but he is not that way Cavil is.
