Sonic the Hedgehog
Return to the Death Egg is a complete story written by Ed Reynolds with art by James Kennedy Whitaker and Stephen Davis. The Freedom Fighters visit the Death Egg crash site so Porker can look over the systems. Unfortunately for them, it's still relatively active, and crawling with Badniks...
Knuckles the Echidna
Horror in the Haunted Hill Zone concludes, Ed Reynolds writing and Mike Corker on art duties. Knuckles and Tikal rescue Porker, but Rouge has other ideas. She summons the local ghosts' leader King Boom Boo, in hopes that Knuckles will give her the code for the Chaos Emeralds' box. Can the friends make it out in one piece? And what's happened to Big and Buddy?
