世界コスプレサミット
The February 11–17, 2014 North American winter storm occurred on the days before the convention, causing travel disruptions for attendees. The convention did not share the Gaylord with other events in 2014 and made the dealers' room larger. Registration experienced significant delays due to staff and organization issues. Katsucon again held events for the World Cosplay Summit. The dress code was changed by the convention and hotel for 2016. Katsucon 2021 was cancelled due to the COVID-19 pandemic.
