A timeless threat! Kang the Conqueror, the time-traveling despot determined to rule the timestream, has menaced the Avengers and Fantastic Four for years. But when the Vision tries a new strategy against their longtime nemesis, he ignites a temporal war - and Kang's first strike is a killer! Can a team of Avengers gathered from across time save history? Plus: Kang sends Kamala Khan back to the Avengers' earliest days; battles symbiotic threats with Spider-Man, Rocket Raccoon, the Black Knight and Monica Rambeau; and targets Moon Knight's patron, Khonshu! And can the FF survive when Kang's many personas - from Rama-Tut to Immortus - unite against them?
