Franchise history 
The Monsters, originally known as the Kentucky Monsters, were created due to a dispute with the Northern Kentucky River Monsters, who played the UIFL's inaugural season in Highland Heights until the team and the UIFL agreed to part ways. The latter Monsters were created in an attempt to retain the UIFL's rights on the Bank of Kentucky Center and to prevent the original tenants from using the arena. (The UIFL also secured the rights to the Cincinnati market, via the Cincinnati Commandos, to keep the River Monsters from taking root there as well.) The Monsters said they would maintain the River Monsters' prior records. With the objective of forcing the River Monsters out of the Northern Kentucky market having succeeded, the team never made it beyond the naming of a head coach; the Kentucky Monsters quietly folded prior to the 2012 season without playing any games in the UIFL.
Its intellectual property rights were transferred to a proposed 2013 expansion team set to play in St. Charles, Missouri, a suburb of St. Louis. John Parker, was named head coach. On March 8, 2013, the Missouri Monsters opened their season with a game against the Corpus Christi Fury, losing 74-37 in front of a crowd of 4,092 
On March 26, 2013 Head Coach John Parker was fired, and Martino Theus was named Head Coach effective immediately.
