Collects Avengers (2018) #46-50.

World War She-Hulk! The planet has become more fractured and volatile than ever — especially for the Avengers. And when She-Hulk is declared a global menace, Russia’s mightiest heroes, the Winter Guard, are tasked with bringing her to justice! Now, Jen Walters will face a fate that not even a Hulk could hope to endure. The Red Room is the secret furnace where some of the world’s greatest assassins and super-killers have been forged — and it will transform Jen into something terrifying. The Winter Hulk is about to be unleashed on the world — including a dark and bloody mission beneath the waves in Atlantis! And the only one who may be able to stop her is…Gorilla-Man? No matter who wins, She-Hulk and the Avengers will be changed forever!
