It's probably just for the cover. I don't see this as indicative of Salvador Larroca's work and we've seen his Alien already from the variant covers. No indication of the tongue but it looks like he might go for the "drone".
Very good call. An ongoing series could be an interesting experience given we've never had that before.IS there a site where you can keep track of all comics/volumes in order for these kind of things? Because I tried to follow darth vader comics and star wars but is completely lost with marvel and which order to read them, most annoying is their darth vader: two comic series but uses the same namne, confuses the hell out of me.
Marvel Database keeps track of new releases as well as giving a plot summary of an issue or volume.
In the case of Darth Vader, the first series picks up after ANH, the second right after ROTS, and the current one is after ESB leading into ROTJ. The first and third series tie in a bit with the other books but aren't required reading.
