 Shortly thereafter, the series would be incorporated in the series' second crossover with the "Sonic the Hedgehog" comic lines from Archie, "Worlds Unite".The plot of this crossover centers around Sigma forming an alliance with various other villains-including the Deadly Six from "Sonic Lost World"-from different dimensions in a bid to take control of the multiverse.This prompts the Maverick Hunters-whose membership includes X, Zero, and Axl due to the story being set between the events of X7 and X8-to join forces with Mega Man and the Robot Masters-shortly after the conclusion of the "Mega Man 3" adaptation-and other heroes, including Sonic the Hedgehog and his various allies.
