The Spider-Verse, Part 4

First Aired: March 26th, 2015

Synopsis: Spider-Man returns to his own world and finds that his communicator has conveniently broken. Since he doesn't have the time to visit SHIELD he goes directly to the Hellcarrier, where he finds the Green Goblin powering himself up with a serum made from the DNA of all the alternate universe Spider-Men. Spider-Man sabotages it but it's too late - the Goblin has gained more powers, and to make things worse, he now knows Spidey's real identity. As the fight with Spider-Man continues the Goblin mutates further into the Spider-Goblin, sporting extra limbs and acidic spit. Spider-Man manages to find the Siege Perilous with Electro still trapped inside it. He gets Electro to summon all of the Spider-Men he met over the last few episodes to help defeat the Green Goblin. By working together the spiders are able to hold down the Goblin, and Spider-Man then uses Electro to de-ionise the serum, turning the Goblin back into Norman Osborn.

Synopsis: The next universe Spider-Man ends up in takes him to York, a medieval village. As Spider-Man approaches he sees a figure called the Alchemist extorting money from the citizens in return for protecting them, but Spider-Man's soon spotted and captured, having been mistaken for a witch. He's saved from being burned at the stake by this universe's Spider-Man, an armoured figure called Spyder-Knight, but the Green Goblin soon appears, grabs Spyder-Knight's DNA, and leaves through a portal. Spider-Man wants to follow but a giant steampunk octopus called the Kraken appears out of a nearby lake, which Spyder-Knight has to fight. As much as Spider-Man wants to leave through the portal he stays to help Spyder-Knight, and in battle Spyder-Knight mentions that the Kraken is what the Alchemist protects the people from. Once the Kraken is defeated it's revealed that the Alchemist, this universe's version of Doctor Octopus, was controlling it all along. Although the portal closes, Spyder-Knight takes Spider-Man to Merlin, this universe's Doctor Strange equivalent, and he's able to reopen it.
