Marion Comic Con was held in Marion's new Municipal Event Center (MEC) on March 4, 2018. More than 1400 people from around the region attended to enjoy visiting with industry celebrities from shows such as AMC's The Walking Dead. They also enjoyed shopping and chatting with vendors providing comic books, collectibles and memorabilia.

In addition, many attendees came as their favorite character from anime, comics, science fiction and more and competed in costume contests based on age categories. The event marked the inaugural event in the MEC. Organizers are already planning for next year's show.
