User blog comment:Olórin The White/Who are the members of the Light?/@comment-1635895-20110920062757/@comment-64.247.102.95-20110922182200

L-1 has the same voice actor as Vandal Savage. L-2 has the same voice actor as Ra's al Ghul. L-3 has the same voice actor as Lex Luthor. L-4 has the same voice actress as Queen Bee. L-5 has the same voice actor as Prince Orm AKA Ocean Master. L-6 has a French accent and is shaped like a dome. So probably The Brain. L-7 is the only real mystery. The person is an existing supervillain in comics. If you think that all of the members of the Light were on the Young Justice playing cards, then Klarion the Witch Boy was just below Brain in rank.
