whatever happened to the man of tomorrow?all-star superman?strange visitor story from adventures of superman?......ETC
i personally most prefer is all-star superman.i thought this story has summarize superman's essential elements.and give he a seemingly martyrdom ending(but it's also suggest he has been sccessfully repaired sun,and became a cosmic entity,this made story fitting to superman's optimistic personality)
and strange visitor is my second favourite ending story
whatever happened to the man of tomorrow ending it's a bit disappointed,IMO.
welcome to posts your most preferable ending story,those story didn't need to be complete no other comics related,other stories could complementory to those stories
