If I were a hero, I'd be Martin Luther (Part 2173)...

 Superhero Anydays

Today, by the great John Byrne, we have the cover of Fantastic Four #236.  He was writing and drawing the team at the time.

I'm gonna try to get all these, clockwise, from upper right: Stan Lee, Black Panther, Doctor Strange, Willy Lumpkin (the mailman at the Baxter Building, the FF's headquarters), Spider-Man, Namor, Dardevil, Colossus, Sprite, Wolverine, Angel, Captain America, Yellowjacket, The Wasp , Iceman, Storm The Impossible Man, Cyclops, Beast, Vision, Scarlet Witch, Nightcrawler, Hawkeye, Valkyrie, Hulk, Iron Man, Thor, Ghost Rider, Iron Fist, Power Man, Nighthawk, Hellcat, Shang-Chi, She-Hulk, and Silver Surfer.  

In the middle, we have the Fantastic Four themselves; Human Torch, Mr. Fantastic, The Thing, and Invisible Woman, beneath her and Thing's arm, Franklin Richards (the son of Mr. F and the Invisible Woman), and his governess Agatha Harkness.

And today we also have a genderbent Catwoman.
