Green Goblin (MCU)

Doctor Norman Virgil Osborn is a scientist and the founder and former CEO of Oscorp who, after taking an experimental serum, developed the crazed dual personality that became known as the Green Goblin who wreaked havoc on his city. He had clashed with the Spider-Man native to his reality and was ultimately defeated by him, and died. However, when he was transported through the Multiverse to a parallel universe due to a failure in Doctor Strange's spell he was brought back to life. Lost in this reality, Osborn would seek refuge at F.E.A.S.T., meeting that universe's Spider-Man and his aunt May Parker. As the two sought to cure him from his disassociative personality disorder, the Goblin retook control and murdered May with his Glider. At Liberty Island, the Goblin would have one last showdown with Spider-Man who, in his rage, nearly tore him apart, but was stopped by his native Spider-Man. With an anti-serum provided by him and another Spider-Man, Spider-Man eradicated the Goblin from within Osborn, who would later be returned to his home universe by Strange as a reformed man.
