After evading an entire battalion of security at Area 51, Dr. Quest, Race Bannon, Jan, and Jace finally figure out how to get a signal through to Space Ghost. The good news is that the Guardian of the Spaceways is able to use it to open a portal that takes the Phantom Cruiser back to Earth. The bad news is that the portal also brings one of Dr. Nightmare's mechanical beasts with it! Grown-up adventurers JOE CASEY and SEBASTI N P RIZ pull out all the stops for the thrilling finale of their cosmos-spanning crossover in Space Ghost/Jonny Quest: Space Quest #4 commemorated by carefully curated covers from MARK SPEARS, JOSHUA MIDDLETON, DERRICK CHEW, BEN OLIVER, and CHAD HARDIN!
