If nobody is using their powers then Professor X can't assault Johan's mind. That is of course assuming nobody uses their powers because Johan would be beneath their notice. Anyway, I think some of these guys are beyond Johan's ability to manipulate in one encounter. With enough encounters he could probably break them all, but with a single one I doubt it. Obito though would be easy. I think Itachi would be possible as well give that he was willing to obey orders to murder his family. All Johan would have to do is switch his sense of duty and he may get him to kill himself and/or others. Aizen, no. He is the troll of manipulators. Batman is too smart and has an engrained sense of justice. I think Xavier would be possible. His mind has slipped before with some influence. L would be possible but Light maybe not. He's also a manipulater first and foremost. And Izaya I don't know. Again I think Johan could probably get them all if he had more than one encounter with them but everyone here outside of Obito are of abnormal mental capability. They would take a few tries to crack.
