I finally got the book, and I'm kinda scratching my head over the Parasite's appearance here.
He doesn't seem to have his monster teeth anymore, and he appears to have regained his nose somehow.
I don't know why he's gotten rid of the white stripes that he was sporting before his death (presumably not a costume, but a product of his shapeshifting abilities), but to return to his green speedo and his pre-crisis chest stripe seems like a real step backwards. Of course, you could say that the green undies, again, might be a result of his shapeshifting, but to go from the numerous stripes to a lone speedo once more seems kind of a pointless change, going back in time for the sake of it.
And finally, the way he spoke... well, his speech just seemed a tad too sophisticated for Rudy, IMO. If I were to guess, based simply off of my first impression from his small appearance here, I'd say that Rudy Jones isn't calling the shots with the Parasite's body at this very moment. My bet is that Doctor Torval Freeman is in the driver's seat again. [EDIT]In fact, with all of the pre-crisis elements being so
stealthily snuck into current continuity, I wouldn't put it passed Meltzer to have this Parasite be Max. And, of course, none of the heroes will notice a thing has changed.[/EDIT]
Much remains to be revealed...
