Who is Dampierre's voice actor?

[RWB]

It kinda sounds like Dave Whittenberg(Kefka from Dissidia), but someone told me it's Patrick Warburton... who has a distinctly different voice.

Does anyone know? The Wiki just says ????.

Yeah, I'm pretty sure it is Kefka from Dissidia. I've never heard differently.
