Justice is a health doctor working for the WHO, who travels around the world, defending just causes while breaking a few legs and jaws(he is a Judo master).
Fun fact: Pif Gadget was edited by the French communist party, so Justice never ever travelled to the eastern block or fought evil communists, even if with a few exceptions, Dr Justice was not a political comic.

It's a very masculine universe, GID dominated, and you have to wait the mid-80s to see ONE DID.
