|Missed him, Fartseid!|
Believe it or not, somebody thought it would be a good idea to portray the Elongated Man fighting Darkseid (the ultimate and most powerful villain of the DC Universe) for the Justice League Unlimited promotional art. If that wasn't odd enough, Ralph seems to have the upper hand, and we could only assume that if he decided to attack the most powerful being is because he his brilliant detective mind determined that he has the advantage.
This odd match never actually happened in the comics. There are few degrees between them: The Elongated Man inspired Mr. Fastastic, who was created by Jack Kirby, who also created Darkseid. Even shorter, Darkseid is enemy of the Justice League, of which the Elongated Man is a member. However, they never met and Kirby never even drew the Elongated Man.
I might be wrong, but I don't believe that kind of promotional art comes from Bruce Timm (creator of Batman: The Animated Series, Justice League Unlimited , and the rest of the series in that continuity), the quality does not match his pin ups. At least I don't think he does more than rough sketches, completed by other people. However, this is still a pretty good pic. Darkseid's body looks odd, but Ralph looks awesome. It's rare to find great poses for him, but they just hit the right spot with this one.
