I think they should bring in the guy that does the voice of the futurama charater Morbo.

IMHO Morbo would make a great DK:

DK looks down on humans
Morbo => puny human number one puny human number 2...
DK want to destroy things
Morbo (talking about his wife)=> I WILL DESTROY HER
DK planning to conquer the <img src="/ubbthreads/images/graemlins/div.gif" alt="" /> universe with all the forces of evil
Morbo => Humans have weak knees my race will find this interesting MUHAHAHAHA

So I think Morbo would make a great DK. Probably not going to happing But thats what I tought how the voice of the DK would sound like before the demo was released.

Just listen to this sample (first quote.). I just love the emotion in the voice, the sarcasm,...

I had something like this in mind on how the DK would use emotion and intonation the voice needs to change a bit offcource (a bit deeper,...).

Not in the mood for cheese?
That excuse has more holes than a slice this fine Gorgombert!
