Cracked article time. Be warned about language and a few suggestive themes, kiddies.
Personally, I think Zhukov (Yes, Supreme Commander Zhukov, WWII.) is a generally awesome last name, but I think something along the lines of: Cl'kru'dak Mhle'nurod, Devourer of Worlds would be good enough. It would certainly solve the "My dad could beat up your dad" debates. :b
Not joking around this time.. I really don't know. I'm not a huge fan of my given name, but it's part of what made me who I am, even if I don't particularly identify with it now.
Plugging away in a random name generator doesn't seem to help.. I'd probably just find a word that suits me, translate it a few hundred different ways, and butcher the spelling.
Or, just take Cl'kru'dak Mhle'nurod, Devourer of Worlds. That's a possibility also.
