Never talks, socially inept. Comes off as cool because he never talks and just gets the job done, but he doesn't talk often because he knows that the second he does things go downhill pretty fast and that mystique he built up suddenly shatters as its revealed he's an idiot. Occasionally he thinks he trusts someone enough to speak up, but it goes downhill pretty fast regardless. So mainly just goes along with the mysterious costume and persona so he has an excuse to never talk that often.
Very methodical and good at solving mysteries, but if he was ever framed for some villains activities, its unlikely he could clear himself due to sucking at social norms and explaining himself.
