Being a GERMAN shepherd, he has a German accent. As for temperament and ‘voice’ (like how a character is written, not his actual vox), he is echoed here:
Peter Sellers’ role as Dr. Strangelove–particularly note how he fights against the ‘former’ Nazi part of himself (anthropomorphised by a Nazi Arm).
This is Acey.
-if you’ve never seen Dr. Strangelove, get over yourself and watch it. You don’t need to be of an age to enjoy the ridiculousness and if you are, it’s all the better for its parodiacal (fair-certain that’s not English) humour!
