Drawn for an Ask Caesar answer but I kind of like it enough to put it here too.
I imagine all Bethesda characters went to the same classes to learn how to be antagonists and heroes and suchlike. Caesar isn't jealous of Ulfric's swag. Honest.
While ulfric in my mind is a protagonist I think Cesar and him are similar. Both of their right-hand men like to where animals for hats and their arch-rivals are idiotic generals.
Now that I think on it, one could have made a case for Ariovistus, given the Gallic predisposition for epic mustaches at the expense of beards...and now I want a sandbox set in that time period...
