Invincible Iron Man, Vol. 1 #20A

Tony Stark is gone. His body still persists in a vegetative state, but his mind is completely empty. As his last gambit to defy Norman Osborn, in his living will he gave power of attorney to Dr. Donald Blake... also known as The Mighty Thor. Now, Captain America, Thor, the Black Widow, Maria Hill and Pepper Potts meet to decide the final fate of Tony Stark. He's got a plan to restore himself, but he acknowledges that his colleagues will have to decide whether he deserves to.
