And here we are, folks!
The Guardians of the Galaxy appearing in Avengers Assemble #4!
You can read Byron's advanced review for more, but hopefully we will learn the why's and how's in subsequent issues.
While I haven't been big on what Marvel is doing with their cosmic stable, Avengers Assemble has been generally pretty good.
September also seems some more(?!) cosmic goodness with Jim Starlin Ron Lim reprints, in addition to Thanos and the Guardians appearing in Avengers Assemble #7 by Bendis and Bagley.
Looks like a new era of Marvel Cosmic is here.
For better — or worse!
