About the Groo Hell On Earth #4

Here's where all hell breaks loose. Groo has caused destruction before, but will he be responsible for wiping out all of mankind? Given that this story features dinosaurs, volcanoes, earthquakes, tornados, floods, droughts and the biggest threat of all (Groo), it seems imminently possible. Brought to you by the same people who've been bringing you Groo for twenty-five years now: Sergio Aragones, Mark Evanier, Stan Sakai, and Tom Luth.
