User blog:Ankit09/Info on Members of the Light and their Arch Nemesis

There are seven members of The Light, who are designated by codenames from L-1 to L-7.
 * L-1 is Vandal Savage in continutes he is a Immortal.
 * L-2 is Ra's al Ghul greatest enemy of Batman.
 * L-3 is Lex Luthor greatest enemy of Superman
 * L-4 is Queen Bee is the ruler of Bialya.
 * L-5 is Ocean Master archenemy of Aquaman.
 * L-6 is The Brain archenemy of Doom Patrol.
 * L-7 is Klarion archenemy of Doctor Fate.

So Doom Patrol with Beast Boy will probably appear is this season.

I believe Ocean Master is Prince Orm as they are both voiced by Roger Craig Smith. In other continuities, Prince Orm is also known as the villain Ocean Master. In this series, no connection has been made as yet between Orm and Ocean Master.
