"Kaiju G'nort" from JLA Classified #9 (DC, 2005) by Keith Giffen, J.M. DeMatteis, Kevin Maguire and Joe Rubinstein
Specifically, from "I Can't Believe It's Not the Justice League", the sequel to the Formerly Known as the Justice League mini-series. JLA Classified ran for 54 issues, publishing contained arcs by a variety of creative teams (some of these arcs were originally meant to be mini-series), and about a variety of eras of the Justice League. Most were set in the the post-Morrison JLA, but they occasionally catered to fans of other periods. There was even a Detroit JLA story! Personally, I would have liked it better if it had done more of that, perhaps alternating more steadily between Silver Age, Satellite, Detroit, JLI and JLA eras, but that's the comic book nerd in me talking.
