If Vel'Koz is...

When Vel'Koz is happy he is Well'Koz When Vel'Koz is on a 7-in-a-row killing spree he is Vel'God When Vel'Koz is tanky he is Well'Protected When Vel'Koz looses his contact lenses he is Sad'Koz When Vel'Koz is doing what he's best he is Nerd'Koz

And if Vel'Koz would be in a certain other universe he'd be Hermaeus Mora. http://vignette1.wikia.nocookie.net/elderscrolls/images/1/12/Hermaeus_Mora_Concept_Art.jpg
