Spider-Man: The Clone Saga

Ben Reilly has spent his life believing he knows who he is — until a violent encounter exposes an impossible truth buried inside his DNA. Somewhere else in the city, Kaine Parker is searching for answers of his own, plagued by fragmented memories, extraordinary abilities and the growing suspicion that his entire existence has been manufactured. When their paths finally collide, Ben and Kaine discover that they share more than the same spider-like powers. They are genetic copies of the same man, created as part of a secret experiment whose true purpose has remained hidden for years.
