Action Comics #9
Superman of Earth 23 fights off a Superman from another universe. Pretty great done in one tale, and with it being Morrison it'll be interesting to see where it plays into the rest of the run.
Amazing Spider-Man #685
Doc Ock finally reveals his true intentions (really like the one last grasp/begging spider-man displays on the first page).
Ultimate Comics Spider-Man #10
, Love the art in this issue. Marquez really brought his game to this issue, and this two page spread is pretty fantastic (also really shows off Mile's amazement at the Ultimates). Man Bendis really made Uncle Aaron just a giant creepo.
