So who is Calvin Ellis? Calvin Ellis first appeared in Final Crisis #7 as an African-American version of Superman who is the President of the United States as President Calvin Ellis (Kalel). Like Clark Kent, he escaped Krypton’s destruction as a baby and was raised by human parents on Earth. He was created by Grant Morrison as an homage to Barack Obama (Obama’s influence in comics will be someone’s academic paper one day, if it isn’t already).
The Earth this happens on is Earth-23, where Black superheroes are the dominant heroes, with Nubia (a character who exists on Earth-1) being the Wonder Woman and the Justice League filled out by The Guardian, Vixen, Green Lantern (John Stewart), Black Lightning, Mister Miracle, and Batman, who is the token white teammate.
Ellis was featured pretty heavily in The Multiversity and is a pretty cool character, abet just an alternate version of Superman.
I don’t think that at this point DC would think to revamp Superman as a non-Clark Kent persona. But after watching Into The Spider-Verse and reading the Ironheart and Naomi comics, I’m really interested in Black superheroes—legacy, alternative or original, who get to lead their own stories and get to be their own people outside of just diversity for good PR’s sake. I enjoy the idea of Riri Williams, but it has been through the Ironheart comics and Eve Ewing’s writing that she has really become a full character.
Frankly, if we are going to introduce into the live-action or animated world alternate versions of Superman (which has been done before), especially non-white variants, I just want it to be done respectfully and with the purpose of telling good stories. Spider-Verse did that for Miles and I’d love for that same effort to be put into another legacy/alt-character.
