The previous volume of World's Finest ended with a prologue issue that sets up the next big arc. Whilst it would have made more sense to have that issue to open this volume, the very first page of #26 sets the wacky tone of this arc, which opens with a splash page featuring Batman, Superman, Robin, Mister Mxyzptlk and Bat-Mite wearing shades whilst walking with a fiery explosion behind them.
As the two fifth-dimensional imps seek the help of the two Super Friends, a new evil has emerged by the name of Doom-Mite from the sixth dimension, wreaking havoc with DC's iconic villains getting their own imp counterpart. With many of Earth's heroes clashing against this trippy army by Doom-Mite, who visually looks like a cross between the Joker and Marvel's Mojo, the unlikely champion that is chosen to compete for the claim of the third dimension is Jimmy Olsen.
Created by Jerry Siegel and Joe Shuster, Mister Mxyzptlk is seen more as a comical villain who uses his reality-warping powers to torment Superman. In the case of Bat-Mite, created by Bill Finger and Sheldon Moldoff, he is the ultimate fanboy who has worshipped Batman to the point of just being a nuisance. In recent years, if not decades, both these characters have been used to acknowledge and poke fun of certain aspects of DC's media history, whether it is Adam West-starred campiness or Frank Miller grittiness.
The comical nature of the fifth-dimensional imps, as well as the winking acknowledgement of DC's history is very apparent throughout this arc. Known for his encyclopaedic love of all things superhero-related, Waid throws in imaginative sequences that sees the titular heroes being transported into multiple dimensions, whilst unlikely heroes like the aforementioned Jimmy Olsen being split off into multiple incarnations, thanks to the impish magic. As unwieldy as the storytelling can be, especially with the amount of Easter Eggs sprinkled throughout, it manages to find an emotional core, surprisingly from Bat-Mite who is trying to learn what it means to be a hero and not just gushing over the Caped Crusader.
Arguably the busiest artist currently working in comics, it is surprising that Dan Mora never feels like he is not giving 100% to his work. While his style is perhaps looser here with the cartoonish designs of the imps, who are placed into Looney Tunes-like situations, the amount of other characters being presented in nearly every page is just outstanding. However, one should not negate the work by Travis Mercer, whose art is displayed when Batman and Superman are plunged into the other dimensions, where their appearance change, most notably a humourous reference to the 70s Super Friends cartoon.
Concluding this volume is #30, which marks the first adventure for DC's holy trinity as Batman and Superman (and Robin) arrive at Themiscyra to help Wonder Woman, solving a murder mystery. With striking art by Gleb Melnikov who maintains that retro aesthetic that defines the series, as well as showcasing the world of the Amazons, but the story itself feels unsubstantial, similar to the two-part storyline that Waid wrote about the initial pairing for Batman and Superman.
Despite the unwieldy nature of this volume, it gives you an idea about what Waid and Mora have in store with Justice League Unlimited. As for the volume itself, it embodies the fun Silver Age antics of this series.
