Spider-Man: The Animated Seriesremains one of the most faithful adaptations of the web-slinger’sMarvelhistory, often foreshadowing events that would later unfold in live-actionSpider-Manfilms. Whether it was Peter Parker’s struggles with the Venom symbiote or his encounters with the multiverse, the animated series tackled many iconic moments years before Sam Raimi, Marc Webb, orthe MCU timelinebrought them to the big screen.
