In The Wolverine (2013), the aging Yashida wishes to make contact with Logan so that he can try to persuade the mutant to voluntarily relinquish his healing powers to Yashida or, if Logan refuses, to steal those powers.
When Logan refuses, Yashida arranges for Logan to be weakened so that his healing factor can be stolen, then fakes his own death and secretly transfers himself to an enormous robot body. Why? In what way was his plan advanced by being thought of as dead?
