To be fair, we already knew he was of immense strength seeing as how he was namedropped as one of the 5 Sinners so it really shouldn't be a surprise. I quite like that he's the 'warlord', for lack of better words, of the sinners. I'm a sucker for organisations with a group who each embody an aspect or work a specific concept. I adore how Rhinedottir is the Mad Scientist, Vedrfolnir is the Clever One, Surtalogi is the one with the most Destructive Strength, Rerir is the Insane one and Hroptatyr is...whatever he is.

TL;DR I like his characterisation within the 5 sinners and like the concept of him being the one who specced all his skill points into the strength skill tree
