Can your character be affected by mind control? Yes, but he might eventually be aware that something like that is happening. Is there anything he just CAN'T make them do? It would be hard to make him do something that would effect the balance of demons/earth and other dimensions/etc. It's not entirely impossible, especially since the City doesn't really have anything like that. However, Strange is programmed to value that kind of thing above all else, even if it isn't strictly his "job" anymore. Are you open to him pushing your character's mind? Yes. If so, in what ways would they be most vulnerable to manipulation? Personal relationships and anything regarding his failures as the Sorcerer Supreme. Are you open to him erasing/implanting memories (if so, what kind?)? Yes. The above would also work pretty well for this. Is there anything you don't want him pushing for/mentioning ever? No, everything's good. Are you open to him pushing other characters for information on your character? Yes.
