Left Cover (Standard Edition): Features classic 90s-era X-Men characters including Wolverine, Jubilee, Cyclops, Storm, Jean Grey, Professor X, and others. The cover art is by Pepe Larraz and Jim Charalampidis.
Right Cover (Variant Edition): This is the highly sought-after "X-Gwen" variant cover, drawn by Ryan Stegman and colored by Sonia Oback. It features Gwen Stacy in an X-Men-themed costume with other characters in the background, making it a popular collector's item.
The series was developed to capture the tone and feeling of the classic X-Men: The Animated Series from the 1990s, and Marvel officially placed it in the same universe as the cartoon.
