My super mammal man will fight crime and evil while bringing joy and happiness to all he encounters.
To add depth and intrigue the main character will have a hidden identity forcing him to live two very separate lives - one in the public eye and one in his hidden man-cave of light and love. A cave from which he only emerges to make uplifting changes in the world around him.
I am of the opinion that the world could do with even more light and love and stories on the subject...
