Synopsis

Returning to his own reality, Spider-Man discovers a terrifying transformation: the Green Goblin has spliced himself with the DNA of Spider-Men from across the multiverse, becoming the monstrous Spider-Goblin. With the aid of Electro, who draws power from the Siege Perilous, the Spider-Goblin summons all the Web-Warriors – the myriad Spider-Men of other worlds – to confront them and safeguard New York, even as Electro plots its destruction.
