The Incredible Hulk #4

In "The Monster and the Machine!", Bruce Banner, trapped in the Hulk's monstrous form, uses his own gamma-powered machinery to regain control—only to find himself dangerously weakened. Taking a bold risk, he reactivates the device, merging his mind with the Hulk’s body, unlocking a new, shared control over the transformation. The story explores the fragile balance between man and monster, with the machine now the key to their uneasy coexistence.

In "The Gladiator from Outer Space!", the Hulk faces off against a mysterious alien warrior claiming to represent an invading force demanding Earth's surrender through combat. When the green giant accepts the challenge, he soon discovers the battle was a trap orchestrated by the Russians, who seek to exploit his strength and create a new army of hulks.
