I tried finding info on this in other threads and came up empty handed, so I don't know if this has been covered. So, like, spoilers or somethin' ahead, I don't know....
I was re-reading my IC tie-ins the other day and I got to thinking....(a dangerous pastime, I know).
Supposedly, the Villian's United Mockingbird is the REAL Lex Luthor (he also admits to being a liar, so we can't really take his word).
We also know that a Lex Luthor calling himself Mockingbird first appeared way back in the first several issues of the latest Teen Titans series dropping info on Superboy's origins.
Would it be safe to assume that these are the same Lex Luthor?
If we are to assume this, would this have been the same Luthor that teamed up with the Braniacs, said the magic words that makes Superboy shave his head, and nearly took out the Titans and Outsiders?
If, the answer to the above is yes, why would Mockingbird Luthor try to take out Superheroes? Why not turn the Braniacs and Luthorboy at the Secret Society Lex?
My thoughts on this:
Both Mockingbirds are the same, but it wasn't Mockingbird Luthor that sicced Luthorboy on the Titans.
"The Real" Luthor comes up with the Mockingbird persona to get rid of "SS" Luthor, by striking from the shadows.
He emails Robin re: Superboy's two daddies, in hopes that the boy trained by the World's Best Paranoid, would actually do something about it and take away that weapon from "SS" Luthor. However, he did not count on Robin keeping it secret, and "SS" Luthor decided the time was right to launch his plan ("Take out the sidekicks/former sidekicks and the Heroes will fall") mainly to distract the heroes and solidfy his society.
Mockingbird Luthor, seeing his previous plan fail, swings his "Six" plan into full gear.
Having said all that, I think we'll end up seeing that both "MB" Luthor and "SS" Luthor are actually the SAME Luthor, and that he has a split personality as a result of the events of the 1st 6 issues of Superman/Batman....
Or am I thinking too much?
