History
ColossalCon was started in 2002 and began as a one-day convention in Strongsville, Ohio. In 2003, it became a three-day convention and moved to the Holiday Inn Cleveland South Independence in Independence, Ohio where it remained until 2007, except for 2005 when it was located in the Embassy Suites. The convention for 2008 moved to the Hilton Cleveland East / Beachwood in Beachwood, Ohio, and moved again in 2009 to the Kalahari Resorts and Conventions Sandusky in Sandusky, Ohio where the convention has been located since. During the 2010 convention a tornado hit the area surrounding the venue, hotel and convention guests were sent to the basement for shelter, and the venue suffered no damage. The convention is considering an attendance cap due outgrowing Sandusky's hotel room capacity. In 2017, the water-park remained open extra hours for the convention. Nostalgiaconventions.com LLC (ColossalCon) filed a complaint against Colossus Con in 2017 for using a name too close to ColossalCon.
ColossalCon 2020 was moved from June to September due to the COVID-19 pandemic, but was later cancelled.
