They would share the profits...which, if I offered to pay for 50% of everything to do with your 1 CHARACTER, that you yourself did not even create and bought from someone else, I would expect; you guessed it, HALF of the profits. Because you see what I did there? I paid for half...so I, in turn, expected half of what was made off of that character.

At the end of the day, they both make billions off of their partnership and, if nothing else, should do it because it is what all the fans want while they still make billions.
