Your favorite decapitations

Mine would have to be:
1.) Anakin killing Dooku in Yoda's vision (I like this one more than the RotS one; it captures the demise of Dooku and Anakin's growth in power better for me).

2.) Maul killing Pre-Vizsla: twas an honorable death

What are yours?

The decapitation of Commander Appo, and Vader musing that he had been fond of him

The ones where the guys are speaking Arabic and the condemned are wearing orange suits

Duh.

Damn respect

The decapitations of Dooku and Sirak primarily as how they serve as transformative moments for the decapitators. Sirak secondarily because the decapitator was Bane and because of the line "Those who beg for mercy are too weak to deserve it." Dooku secondarily because of the line "DEW IT" and because of the derpy face Anakin makes while he's doing it.

The decapitation of Pre Vizsla as well primarily because it demonstrates Pre Vizsla's honor and gives the character the closure of getting decapitated by Maul and the very same blade that would go on to kill Dutchess Satine. Secondarily because Maul is a badass and his takeover of Mandalore was where he peaked in TCW.
