Batman as an owl basically… Grant Morrison 1999 redesign of Owlman for JLA: Earth 2
The Owlman character was revived (along with his teammates) in the late 1990s for modern DC continuity in the graphic novel JLA: Earth 2. This Owlman was developed to be reflective of the modern readers with a far darker attitude and background than either of the two Earth-Three depictions.
Writer Grant Morrison and artist Frank Quitely brought the Crime Syndicate of America back to DC continuity in JLA: Earth 2. The Crime Syndicate was a twisted mirror image of the Justice League and had first appeared in Justice League of America #29 in August 1964.
