Reminder that Superman is everyone’s dad when he needs to be.(r/TwoBestFriendsPlay)
All-Star Superman is considered one of the best, really highlights what makes Superman great showing his strength and morality.
Superman Red Son is a “what if” story where Superman landed in Soviet Russia instead of the US. It does an excellent job of addressing the nature vs nurture question and if growing up in the Stalin regime would still lead to the Superman we all know.
Kingdom Come, kinda cheating for this list but I couldn’t help it. It’s so fucking good. More of a Justice League story, but Superman is such a central part of the story. Some of the best art ever in a comic, and is a self contained story dealing with the future generation of heroes and what happens when it’s old vs new.
