#1/most powerful DC Hero BEFORE Superman
With the floating timeline, Superman was born in the late 20th, but didnt come into his own until the early 21st, century, where he's definitely the #1, most powerful hero in DCs heroic community.
I'm asking, prior to that, in the 20th century, what hero claimed those spots?
Was it two heroes (As an example, at Marvel, Captain America can lay claim to a Superman like #1 hero spot, but not the most powerful spot)?
Was it Martian Manhunter, who'd been on earth for some time? Allan Scott or some other JSAer?
Someone else entirely?
Its Hero VS Hero for the top DC spots in your opinion.
This is strictly in universe (no sales figure nonsense), and doesnt include the DCnu; Post Crisis up to just before the 2011 reboot.
