Yeah, Sinestro was one of the wild guesses. Not even my wild guess, but i didn't have anything better. Kobra might possibly be L-7, I guess, hadn't considered that.

As for the others, Queen Bee and Ocean Master are pretty much dead certs, given their voices actors and the context of the episodes in which L-4 and L-5 appeared. The Brain is fairly obvious, given the accent of L-6. Ra's al Ghul is pretty likely as L-2, also mainly from the context of his episode. I've guess Lex as L-1 because, frankly, who else would be L-1? Grodd is the other wild guess, but seems reasonable given his MO and as an enemy of the Flash (since we've already got enemies of Superman, Batman, Aquaman and more).
