Each year, Marcon hosts special events during the convention. Many of these are directly run by Marcon, such as the Masquerade, some are run by Marcon in conjunction with other organizations, such as the Blood Drive with the American Red Cross, and the Charity Auction, which raises funds for various good causes each year. Still others may be mini-cons within the framework of Marcon, as fan groups, writing groups and others make Marcon their annual gathering of fans.
These events will change from year to year, and some may appear one year, and not appear in others.
Special events scheduled for 2019 will be announced over the course of the year.
