Roar

Roar (trademarked as ROAR) is the name of a wooden roller coaster at Six Flags America located near Upper Marlboro, Maryland. There were originally two roller coasters, with the first one built in 1998 at Six Flags America followed by the second one which was built in 1999 at Six Flags Discovery Kingdom. Both rides were designed and built by Great Coasters International (GCI). In 2015, Discovery Kingdom announced the retirement of Roar at its theme park, but the park later revealed that it was being renovated and transformed into The Joker with I-Box track technology from Rocky Mountain Construction.
