Hannibal Tatu, occassional comics commentator, co-devised the Black Hero Origin Algorithm, which basically states the following cliches concerning MOST black heroes you see in DC and Marvel Comics.
Black heroes are inspired by white heroes.
Example: John Henry Irons, Steel (Superman), John Stewart (Green Lantern), James Rhodes, War Machine (Iron Man), Isaiah whasisname and Josiah X (Captain America), J.J. (Thunderbolt), Monica Whasername (Captain Marvel), Goliath (Giant Man)…
Black heroes have been in the Olympics.
I know Black Lightning. Are there more? Who?
Black heroes have a criminal background.
Storm (pickpocket), Falcoln (pimp), Luke Cage (convicted murderer), Cyborg (petty thief)…
Black heroes grew up in poverty.
Damn near half of everyone I’ve already named… and also Death The Black Racer, Vixen, Bronze Tiger, Icon…
I’ll also note:
Most black superheroes DON’T have their own secret headquarters-- or if they do, it’s part of their group affiliation.
Most black superheroes can’t fly.
Most black superheroes have poorly established secret IDs.
…Which brings me to my gripe about black villains.
Black villains operate strictly on a citywide scale as dope dealers, hired killers and young thugs. They are never the bombastic, world-conquering, time-travelling, space-faring, masterminds-with-evil-henchman that are the banes of most superhero teams and individual archetypes. (Even Black Manta is a stretch.)
Black villains are NEVER major villains.
