Gunther

All I can think of is Gunther from Friends. He is in love with Rachel and has a creepy deep voice and bright white hair. A recurring character, Gunther often appears at Central Perk as the coffee house's manager. He usually is in the background staring at Rachel and getting jealous of her male lovers, and is fluent in Dutch. I didn't even know this was a real name - I had never heard it before and thought it must be made up. Anyway, just sounds a tad bit sketchy to me, but that's just my opinion.

Great middle name material, in my opinion. German jock name.

I really like the German ending of this tough, strong name.

The name Gunther seems very grey in my opinion, but it is still a stand-out name.
