Collects Avengers: Season One, Avengers (2016) #1.
The early days of the Avengers — as you've never seen them before! A hidden foe manipulates the newly assembled team from the shadows, meticulously sowing the seeds of discord and mistrust — and causing the new allies to question the very ties that bind them together as they hunt for the fugitive Hulk. Thor — a shape-shifting alien with a secret agenda? Captain America — a hoax? Iron Man — an enemy conspirator? Their confidence in each other shattered, will the heroes destroy each other before the enemy is revealed? Only the smartest among them will see through the deception...and it's not whom you think! Plus: The modern-day Avengers come together to stand against their deadliest foe! Captain America, Thor, Vision, Wasp, Spider-Man and Hercules face Kang War One.
