"Ben Grimm, Killer!"
The Thing has been captured by Skrulls and transported to the Andromeda Galaxy world of Kral to compete in the gladiatorial Great Games.
Unique to this Skrull planet is that the landscape and social mores are all inspired from the 1920's American Gangster era.
Ben is kept captive due to the Skrulls mental conditioning, which prevents him lifting a hand against his "masters". But he has plenty of fighting to do in training for the Games against other alien slaves.
Back on Earth, Reed Richards is busy modifying a captured Skrull spaceship to carry the Fantastic Four across the infinite reaches of space to find Ben.
