Thunderhawk is an inverted roller coaster located at Michigan's Adventure amusement park in Muskegon, Michigan. Designed and built by Vekoma, the roller coaster originally debuted in 1998 as Serial Thriller at Geauga Lake in Aurora, Ohio. It was renamed Thunderhawk in 2004 following Cedar Fair's acquisition of the park. After Geauga Lake's permanent closure in 2007, Thunderhawk was dismantled and moved to Michigan's Adventure, where it reopened in 2008.
