You could honestly look at any character that suffers from a split personality or one that has a side that is odd and crazy and someone in their life that is slightly more level headed... You could also look at any superhero with a secret identity.
For my example, you could use Joker and Harlequin. While they are both, well, crazy, Joker has a lot more issues, while Harlequin keeps him in line at times.
Another one that is more probable and casual use is someone like Batman. He goes around the day as a playboy billionaire and at night a masked crime fighting crusader. The fact that he has this split, it can be compared with the story of Dr. Jekyll and Mr. Hyde.
I hope this helps!

P.S., i'm not a die hard DC fan, but they have good examples in this case XD
