Finished issue 27, and my goodness...did I just see the Smallville version of Gorilla Grodd? Yes, yes I believe I did. Also this is the best the art has been in this book since we started.
Just got around to reading the issue. That's not Grodd, it's Monsieur Mallah (and The Brain), old Doom Patrol villains. Even less likely to appear than Grodd.
It's kind of sad that the best Superman comic put out by DC is the Smallville tie-in.
