A year after Otto Octavius' demise,[b] Peter Parker plans to propose to Mary Jane Watson, who has just made her Broadway musical debut. While the two stargaze in Central Park, a meteorite lands nearby, and an extraterrestrial symbiote follows Peter to his apartment by attaching to his moped. Harry Osborn, knowing Peter's true identity, seeks to avenge his father Norman's death. Using his father's performance-enhancing gas and Green Goblin technology, he battles Peter to a stalemate, hitting his head and developing partial amnesia. Meanwhile, police pursue escaped convict Flint Marko, who visits his wife and sick daughter before fleeing again. Falling into an experimental particle accelerator that fuses his body with the surrounding sand, he gains the ability to control sand and reform his body with it.
