Sonic the Hedgehog is the fastest thing alive. Mega Man is a super-fighting robot. Together they are the coolest, bluest heroes ever! Blue Blur and Blue Bomber meet for the first time in the crossover event When Worlds Collide ! Dr. Eggman and Dr. Wily have crafted a twisted pocket dimension--the Skull Egg Zone! Sonic, Mega Man, Tails, Proto Man and Rush have found their way into the zone, but how will they find the Doctors in this nightmare world? To make matters worse, Sonic's friends have been turned into the eight menacing Roboticized Masters! Can Sonic and Mega Man overcome these fearsome robot warriors? Can Sonic's friends be saved? And what new weapons can Mega Man gain from this fusion of Eggman and Wily technology?
Volume two of this crossover amps up the action, as Sonic and Mega Man explore the new zone created by Wily and Robotnik, and their companions come into the picture, usually in a roboticized fashion (which the creators seemed to have a lot of fun with). Lots of battles as Sonic and Mega Man learn how to free their friends, and Wily & Robotnik further their nefarious plans. The volume raises the intensity with lots of action, but doesn't really move much plot along. It's a good bridge point, but doesn't stand on its own at all. Fortunately, it doesn't really need to.
Part two of three. It's a shame that tween me never got a chance to read this, because I would have loved it! Bonus: the paper of this volume is better than Volume 1's paper quality.
