Yeah Sand was the original Sandman's sidekick 'Sandy the Golden Boy' after the Sandman took up wearing purple and yellow spandex rather than a gasmask and coat. He's Sanderson Hawkins and also had the ability to become sand, something his mentor never did. 

I only say him once or twice in the background of the show, I noticed in the group pic up top just how many of those characters are Justice Society... Stargirl, STRIPE, Dr. Mid-Nite, Dr. Fate, Hourman, Wildcat, Atom Smasher, and Obsidian. If you count the JSA reserves and include past members of alt Earths, the 7 Soldiers of Victory, etc... like they did in the comics... you'd also include the Ray, Vigilante, Shining Knight, and Huntress. 

So... suffice to say if there's a DCU character not usually associated with the Justice League you want to apply with... let's see it. Constantine, Etrigan the Demon, Azrael, Starfire, a timelost Legion of Superheroes member like Cosmic Boy or Saturn Girl, Grifter [Wildstorm characters could still be used in this], Icon [Milestone characters too, he was only a member in the YJ toon], etc. Instead of Atom Smasher... what if Giganta reformed?!? What if Capt. Cold got League status [he did in the comics for like 5 minutes along with Lex Luthor but nothing came of it...]?! 

[h3]EDIT: And everybody applying remember... if there's more than one hero on your mind and we still need to build the ranks, after two missions you can have a secondary character.[/h3]
