You might remember that the internet broke in half when Steve Wacker jumped from DC to Marvel back in September. The big deal was that Wacker was editor of 52, but it didn't get much mention that he was also the editor of the Legion.
What you might not recall is that just before that happened, Mike Marts surprised everyone when he jumped from Marvel to DC. Over at Marvel, he was a Senior Editor and group editor over the entire X-Men line. At DC, he's still a Senior Editor but I don't know what's in his portfolio besides the Legion (the Newsarama link only mentions the All-Star line, so he's not busy). Last month's issue 24 was his first DC credit.
(Also gone with issue 24 is Wacker's assistant/associate editor Harvey Richards, replaced by Jeanine Schaefer. What does an assistant/associate editor do these days, anyway?)
Newsarama interviewed Marts after the announcement and gave him a DC pop quiz:
Newsarama: Can you name Batman's butler?
Mike Marts: Jarvis. Now wait – Alfred!
NRAMA: Who founded the Legion of Super-Heroes?
MM: Paul Levitz
NRAMA: Where does Wonder Woman come from?
MM: Joss Whedon.
Okay – a pass for now (counting extra credit on #2, and a near waffle on #1).
While I think Marts being on the Legion is a coincidence because he's just taking over one of Wacker's former books, I also think it's a nice coup to get a strong, well-respected editor with a good reputation. Now if he can just get sales up to X-levels...
