About the title
When Zzzax, a seemingly invulnerable electricity-fed monster, begins to threaten life on the planet, humanity's only hope lies in an unlikely alliance between two very different Avengers — Iron Man and Hulk. Alone, neither of them can handle Zzzax's limitless power, but together they have a chance — if they can get along and learn to work as a team before life on Earth is extinguished!
