Apparently at Comic-Con, decks of Young Justice playing cards were given to people that ended up revealing some new characters set to appear on the show. One of them is Rocket, the heroine from Dwayne's Icon series!
I apologize for the low quality, but Rocket is next to Zatanna

Does this mean that the Milestone characters aren't off-limits for DC's animation department?
