>>99811698It helps that Doc is a very skilled voice actor, his portrayal of Doctor Mrs. Monarch is built around his doing a very feminine voice (using pitch instead of volume for emphasis, ending statements softly rather than with a hard ending, that sort of thing) but in the lowest register he can do. It's a very weird combination, but he's able to pull it off to the point where after becoming accustomed to it it really does register as "unnaturally deep-voiced woman" rather than "man doing woman's voice".
