All depends on what Robin. I'd say that Tim is probably an INFJ for sure. He can be social but is far more to himself than Dick was. He has a private life and seems to withhold a lot of personal torment from others. He feels for the people in his life very deeply (to the point of attempted cloning) and recently Ra's said that Tim has so much potential because of his ability to work very accurately through his lightning fast intuition. Damn, now I realize why I like Tim so much.
I'd say Dick is an ESxJ honestly. A lot more social (for being a member of the bat family), he lives through his senses (with ladies, acrobatics, etc), the T/F function is tricky depending on the writer, and if he wasn't a crime fighter I'd say he was a P, but organization is sort of required of and forced upon him and it's his life 24/7.
Jason is too much of a mess to sort out... Damian is the same, though I'd assume ST for him.
we're definitely ALL superheroes. And I'm surprised no one has had the brilliant idea to all move into a tree fort together.
Is it that by its indefiniteness it shadows forth the heartless voids and immensities of the universe, and thus stabs us from behind with the thought of annihilation, when beholding the white depths of the milky way?
