Best “Head” Character?
- May not be – or is probably not – an actual Head character.
I think Baltar’s head-Six is the best.
She has so many dimensions, such a range of emotions and motives.
head baltar (ZZZZZ) are the best in my opinion and head six was great an episode ago with more guns 
Got to go with Head Six here…
Now does this mean that her father was a human??? or could he still have been the number seven Cylon?
Head Lance of course.
I think all the head characters are great, in an extra-consciousness, make you look at things from a different perspective kind of way, but head!Lance was incredibly tragic and compelling and gave us such incredible insight into the tortured soul of Romo. Head!Dreilide is a close second for me.
I have loved Head Six since the beginning. But I voted for Non-Creepy Leoben because he led Starbuck straight to annihilation as part of some greater plan. To me, that makes him really, really mysterious and slightly cooler than Head Six.
Now, I have always thought both appearances of Head Baltar were of the same entity, one appearing to Baltar himself and then the other appearing to Caprica Six of course. They were the same suit after all! 
Head Baltar. I love his British-accent cynicism.
Baltar’s Head Baltar - “You slay me, you really do, Gaius.”
Even his own head character is arrogant regarding himself.
