Event Details in the Series
While this series is a reboot to The Avengers: Earth's Mightiest Heroes! and Avengers Assemble, the show also features an original story which the episodes, unlike most of the ones in Avengers: EMH!, are not adaptations to comic book arcs published for Marvel, although some elements in both Marvel and DC Comics are used.


 * Aunt May is married to Gwen's father George Stacy, making Peter and Gwen step-cousins.
 * Ultron is created by Arnim Zola during World War II era instead of Hank Pym or Tony Stark in modern era. The villain becomes depicted as a Dark Lord who was sealed away for decades waiting for revenge on humanity.
