Upon being brought to K'un-L'un by Iron Fist, Spider-Man and Kid Arachnid meet with Nick Fury, Doctor Strange, and Madame Web who states that the shattering of the Siege Perilous scattered its fragments to many dimensions, and if they are not collected in time, many universes will crash onto another, and eventually, all of the universes would be destroyed. Using the shard of the Siege Perilous, Spider-Man and Kid Arachnid are sent on a trip to the different dimensions to collect the shards. Their first stop is a Victorian era-themed world that's currently infested with vampires. Spider-Man and Kid Arachnid must help the vampire-hunting superhero Blood Spider get the first shard from the Lizard King (a Victorian version of the Lizard) and his most trusted hunter Wolf. The Lizard King plans to use the Siege Perilous shard to block the sun so the vampires can rule the Earth. Although Spider-Man and Kid Arachnid are able to save the day and revert all the vampires back to normal, they find out that Wolf is a spider-based villain himself called Wolf Spider and is from a different parallel world. Wolf Spider is collecting the shards in order to rule the multiverse and he knows Spider-Man's identity of Peter Parker.
