I had to vote Swamp Thing. I was a fan of Image Comics when they started and bought every title released the first 3-4 years. There were gems and there were some junk titles but I liked being on the ground floor for a new universe and throwing my financial support to titles which were creator-owned. WildCATs was a favorite back then. Jim Lee’s pencils were gorgeous.
The CATs would be my second choice. The old cartoon was not good, as I recall, so seeing a new one would be very cool. Grifter’s appearance in Flashpoint kind of made the movie for me. It was a really good movie aside from that and then, BOOM!, Grifter is on screen. For me, total fanboy moment there.
Swamp Thing, though, I think it was a totally bad decision to cancel the new DCU Original series. It didn’t even get to the second episode and it was cancelled? Boo! Hiss! Maybe it will get a second shot soon.
