If i were a hero, I'd be Martin Luther (Part 4620)....

 Superhero Anydays

Today, by someone named Darryl Young, we have what can only be called a group of D-List DC heroes.  Since they're all youngish and/or sidekicks (and three of them were part of the Teen Titans in the 70s) perhaps they're main team Teen Titan wannabees? 

Supergirl, Element Girl, Golden Eagle

Lilith, Guardian, and Airwave

And today we also have cosplayers doing the Earth-2 Alan Scott Green Lantern with the Earth-2 John Stewart Green Lantern. 

And the second one could even be doing a cosplay of Idris Elba portraying John Stewart?
