Keith Giffen does mainstream crossover event, and does it well. Here we cover the 2006 epic war story that is Annihilation. The brainchild of editor Andy Schmidt along with Giffen, this story features the "cosmic characters" in the Marvel lineup. Galactus and Silver Surfer? You know it. Thanos. Of course. Rohan? Yep. And a star turn for the main villain, who is not much of a surprise when you think about the title of this series. This series also leads very directly to the creation of the modern Guardians of the Galaxy. But back to cosmic folks: Giffen's writing is fun and crisp and tells an epic tale. But for the real gem, we suggest the Drax mini-series that preceded the main event.
