Who are the closest DC Comics equivalents to the four main characters?
I read that collectively, the Fantastic Four as a unit was meant to be Marvel's answer to the Justice League:

The Baxter Building is their take on the Fortress of Solitude, i.e. a home that has technology and gizmos and stuff and portals into other dimensions (Phantom Zone/Negative Zone). Likewise, Reed Richards and Doctor Doom are very much based on Superman and Luthor being a rivalry where The Cape opposes a Mad Scientist who wants to Take Over the World with the latter having an Irrational Hatred for the hero.
Or more directly, the Challengers of the Unknowns:
