Rule needs clarification

[Draaka]

Me and my friends are having a debate about whether special powers are optional?

Example:

My emperor possesses a friends Vader, when Vader gets killed and his window is white, can I choose not to stand him up again?

The rules on the hasbro website aren't clear on this.

Indeed it isn't clear, and as a family we'd always had them optional. The committee ruling is as follows:

Are Special Powers Mandatory?
3. All powers are mandatory other than those that could be passed on during normal play.

Cool, thanks!
