I'm trying to find a word that describes someone who has all at once the qualities solemn, aloof, and stoical -- a word that one would use when looking at a sort of dark and brooding but admirable hero character. He/she doesn't necessarily exude these qualities all the time, but there are moments where the only way to describe them in one shot is with a word like this.
Unfortunately the most relevant example that comes to mind is Batman. Something like the image I've included below. Another character that comes to mind is Draco from Dragonheart (if you've seen it).
I don't really like asking thesaurus-like questions here, but I've been searching extensively and can feel the madness setting in (haha).
Update: Some of the words I've considered so far have been stoic/stoical, stern, austere.
Thanks for the tag modifcations. I was unaware there was a specific tag for this type of question.
