During the first season, corrupt industrialist Norman Osborn targets Spider-Man in the shadows in hopes of collecting his DNA to create a spider-soldier army to sell to the government. To do this, he uses Doctor Octopus as his pawn, having him send numerous supervillains after Spider-Man and use a sample of Spidey’s blood to create the Venom symbiote, which ends up bonding with Harry Osborn, Norman’s son and Peter’s best friend. In the two-part season finale, Spider-Man learns that it was Norman who was the mastermind behind Doctor Octopus’ schemes and Venom’s creation, just in time to see Doctor Octopus take his revenge on Norman for the way he treated him by turning him into the Green Goblin.Marvel’s Ultimate Spider-Man Season 1-2 Download
In the second season, following the fight with the Green Goblin which resulted in the destruction of the S.H.I.E.L.D. Helicarrier, Spider-Man’s team ends up staying at Peter Parker’s house. In the season premiere, after learning that Spider-Man got his powers from one of Oscorp’s genetically altered spiders at the end of last season, Doctor Octopus creates a bunch of serums with animal DNA in hopes of re-creating the process, and S.H.I.E.L.D. scientist Dr. Curt Connors, still dealing with the aftermath of the Helicarrier’s destruction after injuring his right arm and having it amputated, injects himself with one of these serums to become the Lizard. Later, Doctor Octopus controls Lizard so that he can join him, Electro, Rhino, Kraven the Hunter, and Beetle as a member of the Sinister Six. While Spider-Man and his team are able to defeat the Sinister Six, Lizard gets away, and Spider-Man swears to find and cure him. Later the Sinister Six reappears in the penultimate episode with Beetle replaced by Scorpion. During the season, Spider-Man learns more about his teammates’ origins: Ava Ayala having assumed the mantle of White Tiger after her father Hector was killed by Kraven, Sam Alexander being the last member of the Nova Corps since former member Titus wiped the rest out trying to get another helmet and was recruited by the Guardians of the Galaxy, Danny Rand having assumed the mantle of Iron Fist after training in K’un-L’un and Luke Cage had received his powers from a S.H.I.E.L.D. version of the Super Soldier Formula developed by his parents.
