I'm guessing that its members include Queen Bee, Ocean Master and The Brain.

Queen Bee because Greg Weisman said that Marina Sirtis would be voicing her, and since she voiced L-4, it's very unlikely that they would cast her to say 4 lines in one episode if both won't be one and the same character.

The Brain because of his trademark French accent, but it could be another, though the list is short.

And Ocean Master because L-5 and Prince Orm have the same voice actor, so same as with Queen Bee, and it is VERY unlikely that, even if we disregard the shared voice, Prince Orm would not be a villain in this iteration. Especially since the whole episode was a ploy to extricate Starro from Atlantis, which they sort of did. Also, L-5 seems to have spikes on his head, which may very well be from Ocean Master's trademark helmet.

Can't wait to see the mystery solved, even though once it is, I'll wish for more.
