Mirage continued to work independently, distancing herself from villainous activities and eventually aiding superheroes.
After the events of “The Incredibles,” Mirage’s character arc took a turn away from her initial role as Syndrome’s assistant. Her disillusionment with Syndrome’s disregard for human life, particularly when he was willing to let Mr. Incredible die without remorse, led to a change of heart. Following Syndrome’s defeat, Mirage was no longer associated with his nefarious plans. She did not appear in “Incredibles 2,” which suggests that she may have chosen to keep a low profile.
In the broader Incredibles universe, including comics and other media, Mirage has been portrayed as using her skills and intelligence for more positive purposes. She has been shown to assist superheroes, using her espionage talents to gather intelligence on supervillains and to help protect the public. Her character development implies that she seeks redemption for her past actions and wants to make amends by contributing positively to society. While her exact activities post-“The Incredibles” are not explicitly detailed in the films, it is clear that Mirage has moved on from her life with Syndrome and has embarked on a new path, possibly continuing to work behind the scenes in support of superheroes.
