what happened to alfred in the dark knight returns
The Dark Knight Returns Superman tries to reason with Batman, but Batman uses his technological inventions and mastery of hand-to-hand combat to fight him. During the battle, Superman compromises Batman's exoframe, while Queen shoots a kryptonite-tipped arrow to greatly weaken Superman. Batman reveals that he intentionally spared Superman's life by not using a more powerful kryptonite mix; the fight and near-death experience was meant as a warning to Superman to stay out of Batman's way. Before he can fully defeat Superman, Batman suddenly has a heart attack, apparently dying. Alfred destroys the Batcave and Wayne Manor before dying of a stroke, exposing Batman as Bruce Wayne, whose fortune has disappeared. After Wayne's funeral, it is revealed that his death was staged using his own chemical concoction that can suspend his vital life signs. Clark Kent attends the funeral and winks at Robin after hearing Wayne's heartbeat resume. Some time afterward, Bruce Wayne leads Robin, Queen, and the rest of his followers into the caverns beyond the Batcave and prepares to continue his war on crime.
