This set continued the tradition set by Series IV in that it had some larger nine card artwork panels. However, these focused on specific comic book crossovers such as Fatal Attractions and Maximum Carnage. The backs of the cards summarized the progression of the plot of the crossover, sometimes related to the character on the front of the card, sometimes not. However, only 81 of the base set cards (200 cards total) were of this style. The majority of the cards were simply an alphabetic organization of heroes and villains (including Marvel 2099 cards, which played a more prominent role here).
