Poor David Banner.
Poor Dr. Green.
These characters from two popular television shows get more than their fair share of getting messed with. (Spiderman is another example, though perhaps to a lesser extent). From a cpaes perspective, I think all the players who play them are against them to create dramatic tension at every moment.
If I put out a goal: <my hulk character> avoids hulking out and end up winning the conflict; do I have to narrate that he was successful or can I merely explain how he failed?
I get the impression I can narrate whatever I want as long as it resolves the goal; whether or not it is in "my" character's best interests.. Am I wrong?
If you win the conflict, you can narate ANY resolution of it.
Yup. I once had a character that was really beginning to annoy Tony, so he slapped down a Goal to kill her -- and I thought, "yeah, this one's really done," so I fought vigorously to win the Goal, narrating how she was getting chopped to pieces, and when I won it, I narrated her dying, just in the way I wanted it instead of letting him control her last words and so on.
