Superman and Clark Kent behave differently, but Clark is the real personality. He is often portrayed as the quintessential all-American boy-next-door type, as well as a simple (as in a minimalist, not stupid) farm-boy — equally a jock who enjoys playing sports like football and baseball, and a bit of a nerd who enjoys reading and writing.

The most common description of Clark used for decades is ‘mild mannered’ — meaning ‘gentle and not given to extremes of emotion’.
