Superman/Batman: Vengeance may be he fourth volume in the series, but the story is easily self-contained, kind of. My monthly Comic Bento box brought me volume 4 and I hadn't read any of the other installments yet, so I was a little apprehensive. Beyond some vague Darksied event that I hadn't read, nothing really necessitated any background knowledge to get the main story. We open with Superman and Batman in an alternate universe fighting the Maximums. After killing one of the Maximums, Superman and Batman head back to their own dimension, leaving the Maximums seeking revenge. From here, Jeph Loeb embraces the multiverse of DC and has a stream of heroes and villains from other universes filter in. This includes Bizarro and Batzarro, who try to help Batman and Superman. They are fun characters that can bring some comic relief, but their weird reverse speak in confusing, mainly because not everything is opposite, but you get kind of used to it. As with any multiverse story, Vengeance is convoluted and often confusing. I still enjoyed the story, but it wasn't entirely clear what was happening some of the time. While the story was pretty solid, the art left some to be desired, mainly in the artwork for Superman and Batman; they both look like relatives of The Crimson Chin from Fairly Odd Parents. They have strangely elongated chins with bizarre clefts. They look really blocky and angular, especially when other characters look so normal. Everyone looks to bulky and muscular and has these big anime eyes and most of them do have cleft chins, but Batman and Superman look so bad that I almost didn't notice their terrible take on how The Joker should look. Darksied looks fine, but everyone else has some weird caricature like feature that just throws it off. The art isn't terrible and overly distracting like Dark Knight returns, but it wasn't good. Vengeance was a decent story that had good pacing and I didn't feel like I was missing too much buy jumping in at volume 4, but the sub-par art and confusing story (which seems to be the trademark of a multiverse story) were big negatives.
